Opening script to send contractors
Hi, I'm in Los Angeles, CA and planning a project that includes Heat Pump HVAC, Heat Pump Water Heater, EV Charger Installation, Solar Panels, Battery Storage, Electrical Panel Upgrade. I am looking for a quote that includes: 1. Heat Pump HVAC 2. Heat Pump Water Heater 3. EV Charger Installation 4. Solar Panels 5. Battery Storage 6. Electrical Panel Upgrade Please tell me: - Will you perform a formal load calculation (Manual J for HVAC, Article 220 for electrical)? - Are you familiar with Los Angeles permits and any local rebate programs? - Can you give line-item pricing and separate confirmed incentives from assumed incentives? - Who handles permits, inspections, and rebate paperwork?
Technical basics in plain English
Panel size: 100A, 125A, 150A, 200A
Your electrical panel is the main entry point for electricity into your house. The 'A' means amps. More amps means more total electrical capacity. 100A is older and may not support adding heat pump + water heater + EV charger together without an upgrade or smart load management. 125A/150A is middle ground; could work with efficient equipment and a real load calculation. 200A is usually the cleanest path, but not guaranteed.
Ask: What is my panel size, and can you show me the load calculation that proves this setup is safe?
Load calculation
A load calculation is not the same as guessing. It is a code-based calculation that estimates whether your panel and service can safely carry all major electrical loads. A qualified electrician or contractor should be able to explain whether you need a panel upgrade, a service upgrade, or smart load management instead.
Ask: Are you doing a formal electrical load calculation, or just eyeballing the panel?
120V vs 240V
Normal outlets are usually 120V. Large appliances often use 240V, like a dryer or EV charger. Many heat pump HVAC systems, EV chargers, and some water heaters need 240V.
Ask: Which parts of this project require 240V?
Smart load management
Smart load management lets devices avoid running at full power at the same time. For example, the EV charger may slow down while the heat pump or water heater is running. This can sometimes avoid an expensive panel or service upgrade.
Ask: Can smart load management avoid a service upgrade while still supporting future loads?
Manual J load calculation (HVAC)
Manual J is the standard HVAC sizing calculation. It accounts for home size, insulation, windows, orientation, and ductwork. A good HVAC contractor performs Manual J before sizing the equipment; bad contractors just match the existing furnace tonnage.
Ask: Will you perform a Manual J load calculation before sizing the equipment?
Battery backup: whole-home vs essential-loads
Whole-home backup tries to power almost everything during an outage. Essential-loads backup powers selected circuits (refrigerator, internet, lights, some outlets). Whole-home backup costs more and drains batteries faster. Essential-loads backup is usually more economical.
Ask: Are you quoting whole-home backup or essential-loads backup? Which specific circuits will be backed up?
Specific questions to ask
Questions for HVAC contractors
| Question | Good response | Bad response |
|---|---|---|
| Will you perform a Manual J load calculation before sizing the heat pump? | Yes. We calculate heating and cooling load based on home size, insulation, windows, orientation, ductwork, and infiltration. | We just replace the existing furnace with the same tonnage system. |
| Will you inspect ducts before specifying the heat pump? | Yes. We inspect duct size, leakage rate, return air paths, and airflow because heat pumps need good airflow at moderate static pressure. | Ducts are always fine; no need to check. |
| How do you decide system size in tons or BTU? | We explain tons and BTU using Manual J inputs, not just square footage. | We use 1 ton per 500 square feet as a rule of thumb. |
| What refrigerant does the system use, and is it compliant with current EPA rules? | We specify the refrigerant (R-454B or R-32 for new systems after the EPA A2L transition) and confirm it meets current code. | Refrigerant does not affect homeowners. |
| Are you a TECH Clean California enrolled contractor, and is the program currently funded for heat pump HVAC? | We verify current TECH Clean California program status (single-family Phase I has been fully reserved since November 2025) and explain whether it applies before signing. | TECH always pays out; assume the rebate is yours. |
| Does my household income make us eligible for HEEHRA, and what does that involve? | We confirm income eligibility (below 80 percent AMI or 80 to 150 percent AMI), explain pre-approval is required, and verify program status (Phase I single-family is currently fully reserved per CEC as of 2026-02-24). | HEEHRA covers everyone; you qualify automatically. |
| LA has very different climate by neighborhood. How do you size for our specific area? | LA microclimates split coarsely into coastal (Santa Monica, Venice, Pacific Palisades) with mild summers and ASHRAE 99% heating design temps near 44-46F, basin / mid-city (Hollywood, Mid-Wilshire, Koreatown) which run warmer in summer, San Fernando Valley (Van Nuys, Sherman Oaks, Encino, Burbank-border) with hot summers above 100F and design heating near 38-42F, and San Gabriel Valley / Foothills (Pasadena, Eagle Rock, Highland Park) intermediate. We run Manual J using the ASHRAE 99% station closest to your address and document the assumption; cooling load drives sizing far more than heating in most LA neighborhoods. We share the Manual J output. | LA is all the same climate; one ton per 500 square feet. |
| Our 1940s LA bungalow has a wall furnace and no central ducts. Ducted or ductless? | A large share of older LA single-family stock (Spanish, Craftsman bungalow, mid-century) was built with wall or floor furnaces and no central ductwork. Retrofitting central ducts means losing closet or attic depth and meeting Title 24 duct-leakage requirements; ductless multi-split is often the more honest path: one outdoor unit, one indoor head per zone, low static-pressure losses, and zone-by-zone control. The LADWP CRP rebate tier differs between ducted and ductless; we model both and share the cost-benefit. Ductless typically wins on cost and time for no-ducts retrofits. | We always recommend ducted central; that is what families want. |
| Do LA's seismic requirements affect how the outdoor unit or indoor air handler is mounted? | Yes. California Building Code Chapter 16A and LADBS seismic detailing require that outdoor condensers, indoor air handlers, and any rooftop equipment be anchored to resist seismic acceleration appropriate for the LA seismic design category. We use anchor sizes per the manufacturer install manual and the LADBS seismic detail, including snubbers or restraint straps for ductless wall units in earthquake bracing for the wall mount. We document the anchor schedule in the permit set. Older LA homes with unreinforced masonry or soft-story conditions may need additional engineering input. | Seismic strap requirements only apply to water heaters in California. |
| Our home is in the Hollywood Hills CAL FIRE Very High Fire Hazard Severity Zone. Does that affect equipment siting? | Addresses in the CAL FIRE Very High FHSZ (much of the Hollywood Hills, Brentwood, Bel Air, Pacific Palisades, Topanga, Sherman Oaks Hills) fall under California Residential Code Chapter R337 for wildfire-resistant construction. Outdoor condenser siting in zone-0 (the first 5 feet of defensible space) needs ignition-resistant placement; intake louvers may need spark-arrestor screening; combustible landscaping must be cleared per defensible-space rules. We verify the FHSZ designation against the address through the CAL FIRE viewer, document the citation, and site the equipment accordingly. | WUI rules only apply to new construction. |
| Which refrigerant are you specifying and what does A2L safety mean for an LA install? | Effective January 1, 2025, AIM Act-driven federal rules require new residential heat pumps to use R-454B or R-32 (both A2L mildly-flammable refrigerants) instead of R-410A. Manufacturers have shifted accordingly. A2L refrigerants are safe when installed per the manufacturer install manual; indoor charge limits, leak-detection sensor requirements on ducted systems, and equipment-room ventilation rules apply. We document the refrigerant, the charge, and any required leak-detection sensor in the proposal and confirm LADBS will sign off. | R-410A is fine; we'll just use what we have in the truck. |
| If we go all-electric, what happens to the gas furnace and the gas line? | When the gas furnace is removed and the home does not need gas service for water heating, cooking, or laundry, the gas line to the furnace is capped, labeled, and pressure-tested per California Plumbing Code. Full meter removal (a SoCalGas service request) is the homeowner's choice and saves the monthly SoCalGas service charge. We document the cap location and capping detail in the permit set. We do not yank the gas line without a permit and inspection. | We just disconnect the gas; SoCalGas does not care. |
| Do you run Manual S and Manual D in addition to Manual J, and do I get the outputs? | Manual J sets the load; Manual S selects equipment to meet that load (capacity at design conditions, modulation range, defrost behavior); Manual D sizes ducts to deliver airflow without static-pressure penalties. Many older LA homes inherit undersized return ducts that throttle airflow no matter the equipment. We run all three and share the outputs, including any required duct modifications as a separate line item. Skipping Manual S or D is how a right-sized system underperforms by 20-30 percent. | Manual J is enough; everything else is overkill. |
| Where will the outdoor unit go and is there an LA noise ordinance to worry about? | Los Angeles Municipal Code Chapter 11.12 (Citywide Noise Ordinance) limits residential property-line noise to 50 dBA at night in most R-1 zones. A modern inverter outdoor unit runs 55-65 dBA at 3 feet; with setback distance, sound-isolation pads, and orientation away from neighbor bedrooms it generally meets the ordinance. We document the unit sound rating, the proposed setback, and any sound-isolation hardware in the proposal. We do not place the unit somewhere we have not verified meets the ordinance. | Just put it wherever; LA does not enforce the noise rule. |
| What does commissioning look like at the end of the job and do I get the report? | At commissioning we verify static pressure with a manometer (target around 0.5 in.w.c. on most residential ducted systems), set airflow via measurement at each register, verify charge by superheat or subcooling per manufacturer spec for R-454B or R-32, log compressor amp draw, and confirm thermostat communication. We provide a signed commissioning sheet with measured values. Without commissioning even a right-sized system can underperform 20-30 percent. The LADBS final inspection card is separate from the commissioning sheet. | Commissioning is an upsell; modern equipment self-tunes. |
| What warranty terms apply and does our coastal address affect equipment lifespan? | Typical residential warranties on R-454B / R-32 heat pumps run 10 years parts and 1-2 years labor when registered with the manufacturer within 60 days; some platforms (Mitsubishi Diamond Contractor, Daikin Comfort Pro) extend labor to 10-12 years when installed by certified contractors. Outdoor units within roughly 1-2 miles of the Pacific (Santa Monica, Venice, Pacific Palisades, Palos Verdes side of LA) see salt-air exposure; we either specify the manufacturer coastal package (corrosion-resistant coil and fins) or document why standard equipment is appropriate. We register the warranty on your behalf and share confirmation. | Warranty is automatic; the salesperson handles it. |
| We are in the San Fernando Valley and summers regularly hit 105F. Does that affect sizing? | Yes. San Fernando Valley addresses (Van Nuys, North Hollywood, Burbank-border, Encino, Sherman Oaks, Northridge) have ASHRAE 1% summer design temps in the 95-100F range, with extreme days touching 105-110F. Heat pumps lose some capacity above 95F outdoor, so equipment selection at the cooling-design point is what matters. We confirm the rated cooling capacity at your specific ASHRAE 1% design temp from the manufacturer extended performance data, not just at the AHRI nominal 95F. We also confirm the refrigerant charge band at high ambient. We document both in the proposal. | AHRI 95F rating is all you need to look at. |
Questions for water-heater contractors
| Question | Good response | Bad response |
|---|---|---|
| Where will the heat pump water heater go, and does the location have adequate air volume? | We assess garage and utility room candidates (heat pump water heaters need roughly 700 to 1000 cubic feet of conditioned air around the unit, or a ducted exhaust path), evaluate noise impact, and confirm clearance per the manufacturer's install manual. | Any closet works for a heat pump water heater. |
| How will you handle the condensate drain? | We route a gravity drain to an approved disposal location or use a condensate pump; we explain freeze risk and overflow safety per CPC, and itemize the work in the quote. | Condensate isn't really an issue. |
| How will you size the tank, 50, 65, or 80 gallons? | We size from household occupancy, peak-hour fixture demand (showers, dishwasher, clothes washer simultaneity), and recovery preferences. A typical 3-to-4-person household lands on a 65 or 80 gallon unit to compensate for slower heat pump recovery vs gas. | Match the gallons of whatever tank is there now. |
| What is the first-hour rating of the proposed unit, and is it sufficient for our peak demand? | We provide the manufacturer's first-hour rating (gallons delivered in the first hour of peak use) and compare it to your typical morning or evening peak demand. We may suggest a larger tank or a mixing valve strategy when the rating runs tight. | First-hour rating isn't really relevant. |
| What is the Uniform Energy Factor (UEF) of the proposed unit, and how does it affect rebate eligibility? | We document the UEF on the spec sheet (modern heat pump water heaters typically range 3.0 to 4.0+ UEF). Many rebates require UEF at or above a threshold (often 3.0) or a NEEA Advanced Water Heater Specification tier rating; we confirm the eligible tier before submitting. | UEF doesn't matter for rebates. |
| Will the install be ambient (drawing from the room) or ducted? | Ambient installs are simplest and cheapest in a garage or large utility room. Conditioned-space installs may need ducted intake or exhaust to avoid cooling the living space; ducting adds labor and material cost. We model the tradeoff in the quote. | Ducting is always required. |
| What operating modes does the unit support, and which one do you recommend by default? | Most modern units offer heat-pump-only (most efficient), hybrid (heat pump plus resistance backup on high demand), and resistance-only (emergency or cold-snap) modes. We recommend hybrid as a default and explain how mode choice changes runtime and operating cost. | Modes are a gimmick; leave it on resistance. |
| What is the manufacturer warranty on the tank, the heat pump compressor, and labor? | Most residential heat pump water heaters carry a 10-year tank warranty and a separate compressor warranty (often shorter). We provide the spec sheet and itemize our labor warranty separately so they aren't confused. | Lifetime warranty; no fine print. |
| If we are switching from gas, how will you decommission the gas line? | We cap and label the abandoned gas line per CPC, pressure-test or visually verify the cap, and remove the abandoned T&P discharge pipe if it conflicts with the new install. The work is itemized in the quote. | Just leave the old gas line where it is. |
| What is your post-install commissioning checklist? | Commissioning includes pressure testing the plumbing, verifying the T&P relief valve and discharge routing, confirming the condensate drain runs free, setting the default operating mode, and walking through the app and any user controls. | We turn it on and leave. |
| What is the expected recovery time after a high-demand event, like back-to-back showers? | In heat-pump-only mode, recovery is slower than gas (typically 2 to 3 hours to reheat a depleted tank). Hybrid mode shortens that. We explain mode tradeoffs and may recommend a larger tank or a mixing valve strategy when recovery is a concern. | Recovery is the same as gas; no tradeoff. |
| Our gas water heater is in the garage. Can the HPWH go in the same spot? | Yes typically. HPWHs work fine in unconditioned LA garages (especially in basin / Valley summer heat where the HPWH actually helps cool the garage). The HPWH does pull about 700-1500 CFM through the unit's intake; small or sealed garages may need vent louvers or ducted intake / exhaust per the manufacturer install manual. Cold-weather performance drops below about 40F ambient (rare in LA garages but possible in foothill / canyon addresses). Hybrid models with heat-pump-only and electric-resistance modes mitigate that. We size the garage volume, confirm clearance, and document the install configuration. | HPWH only works in conditioned space. |
| What tank size do we need for our LA household? | Sizing uses First Hour Rating (FHR), not tank capacity alone. For a typical LA two-bath family of 4 with morning shower peaks, FHR target is 60-80 gallons. A 50-gallon HPWH typically delivers 65-80 gallon FHR; a 65-gallon delivers 80-95; an 80-gallon delivers 95-110. We size from your household pattern (number of showers, dishwasher / clothes washer usage), not from the previous water-heater capacity. Right-sized HPWH avoids running electric-resistance mode unnecessarily, which is what makes HPWH actually save energy. | Same size as your existing water heater; that's it. |
| How is the HPWH seismically strapped in LA? | California Plumbing Code requires water heaters to be strapped at the upper and lower thirds of the tank to the structural framing, resisting horizontal and vertical seismic load. For LA seismic detailing the strap material, anchor pattern, and connection to wood studs (or masonry anchors for stucco-on-block) follows the manufacturer's seismic schedule. We document the strap detail in the LADBS permit set. Inadequate strapping is a top-three water-heater inspection failure; we get this right. | One strap in the middle is enough. |
| Where does the HPWH condensate go? | HPWHs produce condensate during the heat-pump cycle (typically 2-10 gallons per day in LA's humidity range). Options: gravity drain to a nearby floor drain or laundry sink, gravity drain to the building's plumbing waste system through an air gap, or a condensate pump to lift the condensate to a higher drain. We assess the install location, pick the path that meets CPC and LADBS, and document the routing on the permit drawings. We do not let the condensate drip onto the garage floor. | Just let it drip; it's only a little water. |
| Which HPWH refrigerant and brand do you recommend? | Common 2026 HPWH choices: Rheem ProTerra (R-134a, also a plug-in 120V variant), A.O. Smith Voltex AL (R-454C, A2L low-GWP), Bradford White AeroTherm (R-134a), Stiebel Eltron Accelera 300 (R-134a, German engineering, premium price), Sanden SANCO2 (CO2 / R-744, split-system, highest efficiency, premium price, well-suited to cooler ambient). We compare on: First Hour Rating, recovery rate, UEF or HPWH efficiency rating, warranty (tank, parts, labor), refrigerant GWP, and local service availability in LA. We do not push one brand; we share the comparison. | Rheem is the only option; nothing else is worth considering. |
| What happens to the gas line when we swap to HPWH? | When the gas water heater is removed and the home still has gas for cooking or the furnace, we cap and label the gas line at the water-heater location per California Plumbing Code, pressure-test the cap, and document in the permit set. If the HPWH is the last gas appliance, full meter removal is your choice (a separate SoCalGas service request); decommissioning the meter saves the monthly SoCalGas service charge. We do not yank the line without a permit and inspection. | Just disconnect the gas; SoCalGas does not care. |
| What warranty terms apply on the HPWH and on labor? | Typical HPWH warranties: tank 10 years (most brands; A.O. Smith Vertex AL 10, Rheem ProTerra 10, Bradford White 10, Stiebel 10), heat-pump components 10 years (some brands 6 years on the compressor specifically; we read the fine print), labor 1-2 years from the installer. Registration within 60-90 days of install is required for most manufacturer warranties. We register on your behalf and share the confirmation. We list our labor warranty in the proposal separately. | Warranty is whatever the box says. |
| How do you commission the HPWH and what modes do you set? | At commissioning we set the operating mode (heat-pump-only, hybrid, electric-resistance, or vacation), the temperature setpoint (typically 120-125F for legionella prevention plus burn safety), confirm the condensate drain flows, verify the seismic strap, log the unit's serial number and warranty registration, and walk through the app or wall-panel together. The signed commissioning sheet lists the measured values. The LADBS final inspection card is separate. We recommend heat-pump-only mode for normal LA operation; hybrid mode kicks in electric resistance during high demand which is what makes HPWH less efficient than advertised. | Commissioning is just turning it on. |
| Our home is in Santa Monica near the ocean. Does that affect HPWH selection? | Salt-air corrosion within roughly 1-2 miles of the Pacific can shorten the outdoor or garage-mounted compressor coil life. Split-system HPWHs (Sanden CO2 in particular) site the compressor outdoors, which makes salt-air mitigation important. Integrated HPWHs (Rheem, A.O. Smith, Bradford White, Stiebel) have the compressor inside the unit's top housing in a conditioned garage, which is less exposed but still factors in. We confirm the install ambient with you and either pick an integrated unit (often the simpler answer for coastal LA) or document the manufacturer's corrosion-warranty exclusions for the coastal install. | Corrosion does not affect water heaters. |
| What is the recovery rate and why does it matter? | Recovery rate is the gallons of cold water the unit can heat to setpoint per hour at steady state. For typical HPWH 50-65 gallon units recovery is 18-30 gallons per hour on heat-pump-only mode (slower than gas tanks, which is why FHR matters for peak demand). LA households with morning shower peaks may need higher FHR (more storage) than recovery to handle the peak. We size for both: FHR for peak demand, recovery for resilience after long use. We share the math. | Recovery rate is the same on all water heaters. |
Questions for solar + battery installers
| Question | Good response | Bad response |
|---|---|---|
| How will you size the solar array for our future electric load (heat pump HVAC, EV, water heater)? | We model expected future usage including planned heat pump, EV miles, and water heater, then size the array to offset that load under NEM 3.0 export economics. | We size the system from last year's utility bill only. |
| How does NEM 3.0 change the economics versus older interconnections? | NEM 3.0 cut export compensation by ~75 percent versus NEM 2.0, which makes battery storage important for self-consumption. We model expected savings under NEM 3.0 specifically. | NEM 3.0 is the same as NEM 2.0 economically. |
| Is my roof suitable for solar, and what is its remaining lifetime? | We inspect the roof condition, slope, orientation, and shade pattern; we recommend roof replacement first if the roof is near end of life. | Any roof works. |
| Which panel and inverter brands do you recommend, and why? | We name the specific panel model (wattage, efficiency, temperature coefficient, degradation curve) and inverter brand (string vs microinverter), explain the tradeoffs for our roof, and provide the manufacturer datasheets. | We use whatever is cheapest in stock this month. |
| Will the array use string inverters, microinverters, or DC optimizers, and why? | We choose based on roof shading patterns and orientation: microinverters or optimizers for shaded or multi-orientation roofs, string inverters for unshaded uniform arrays. We explain the cost and monitoring tradeoff. | Microinverters are always best. |
| What does the shade analysis show for our roof across the year? | We run a shade analysis tool (HelioScope, Aurora, or similar) using a site survey and roof imagery, and we share the annual production estimate per panel with shade losses called out. | Shade is not significant. |
| Do you offer a production guarantee, and how is it enforced? | We offer an annual production guarantee in kWh based on the design model, and we explain the remediation path (true-up payment or system correction) if actual production falls below the threshold. | Production guarantees are a marketing gimmick. |
| What monitoring platform comes with the system, and are there subscription fees? | We name the monitoring platform (Enphase Enlighten, SolarEdge mySolarEdge, or similar), describe what data is visible per panel or per string, and disclose any optional or recurring fees. | Monitoring is included; do not worry about the details. |
| If we add a battery later, can we still apply for SGIP at that time? | Yes — SGIP applications are tied to the battery install, not the solar install. As of 2026, only the AB 209-funded RSSE (Residential Solar and Storage Equity) tier remains open to new applications, and that budget is fully reserved with new apps on a waitlist served via attrition; ratepayer-funded General Market / Equity / Equity Resiliency budgets are no longer accepting new applications. We verify current SGIP budget status at selfgenca.com when the battery is added and explain that pre-approval is required before equipment is delivered. | SGIP only counts if solar and battery are installed together. |
| Who handles the PG&E interconnection paperwork, and what is the typical timeline? | We submit the PG&E interconnection application on your behalf, file the city permits, and coordinate Permission to Operate (PTO). Typical PG&E PTO timelines range from 2 to 6 weeks after the city sign-off; we document the expected window in the quote. | Interconnection happens automatically. |
| What is your post-install commissioning checklist? | Commissioning includes verifying each panel reports correctly in the monitoring platform, checking inverter firmware, confirming production matches the design model on a clear day, and walking us through reading the monitoring app. | We turn it on and leave. |
| How will you confirm the roof structure supports the array? | We perform a structural assessment including rafter sizing, spacing, and condition; for older or unusual roofs we may engage a licensed structural engineer to provide a letter for the permit submittal. | Roofs always handle solar. |
| How will the array meet California fire-setback rules? | We design the array to meet the California Residential Code fire access pathway requirements: ridge setbacks, hip-to-eave pathways, and emergency egress clearances, and we document compliance in the permit submittal. | Fire setbacks are optional. |
| What ongoing maintenance does the system need? | Typical maintenance is light: annual visual inspection, occasional rinse if local dust or pollen reduces production, and inverter firmware updates pushed by the manufacturer. We explain the warranty implications of skipping recommended maintenance. | Solar is install-and-forget; no maintenance ever. |
| What warranties cover the panels, inverter, and labor? | Panels typically carry a 25 year product warranty plus a 25 year linear production warranty; inverters carry 10 to 12 years standard (extendable); we provide a 5 to 10 year labor warranty separately. We document what voids each. | Lifetime warranty on everything. |
| Does NEM 3.0 apply to a rooftop solar install on our LADWP service? | No. NEM 3.0 (the CPUC's Net Billing Tariff) applies to PG&E, SCE, and SDG&E. LADWP is a municipal utility and is not subject to NEM 3.0; LADWP runs its own net metering policy that credits exports at or near the full retail rate, with bill credits typically between $0.22 and $0.37 per kWh depending on tier and season. That makes LADWP solar economics materially better than IOU NEM 3.0 economics for the same roof: payback usually runs 2-3 years faster on LADWP. We confirm your service is LADWP versus SCE before modeling and document the assumption. | All California utilities are on NEM 3.0 now. |
| Is the old LADWP Solar Incentive Program still paying out in 2026? | The LADWP residential Solar Incentive Program ran out of funds in late 2018 and has not reopened broadly for new applications. The LADWP Solar Rooftops program (a separate offering that leased rooftop space to LADWP) was suspended at the start of the COVID-19 pandemic and is working through a backlog. We do not deduct an SIP rebate from your project cost in 2026. The active value path for LA solar is LADWP's favorable net-metering credit at near-retail rates plus possible RSSE (Residential Solar and Storage Equity) eligibility for income-qualified solar-plus-battery customers; we document both honestly. | LADWP has a Solar Incentive Program rebate that pays for half your install. |
| How do you model expected production for our specific LA neighborhood? | We use PVsyst or HelioScope with NREL TMY3 data for the LA-area weather station nearest your address (LAX for west / coastal, Burbank for the Valley, Pasadena for foothills) and apply a microclimate derate where appropriate. We run a 12-month production model with monthly breakdown, sharing it with you. We do not promise specific kWh production; we provide the model and explain the irradiance assumptions, shading inputs, and module-level performance assumptions. Production typically runs 15-20 percent above SF for the same roof, with Valley addresses at the high end and June marine-layer-heavy coastal addresses at the low end. | LA is sunny so production is whatever the panels say. |
| We are income-qualified. Can RSSE help fund the solar plus battery install? | Yes, possibly. RSSE (Residential Solar and Storage Equity, the AB 209 program) is administered by LADWP for City of LA customers and requires that the system include both solar and energy storage, or that you have an existing solar system and add a battery placed in self-consumption mode. Income eligibility is at or below 80 percent of Area Median Income, or enrollment in CARE, FERA, or ESA. As of February 2026 the program is fully reserved but accepting waitlist applications via sgip@ladwp.com. We apply on your behalf, document the waitlist position, and confirm we are not promising a payout that is not yet committed. | RSSE pays for your whole solar plus battery; sign up after install. |
| Our LA Spanish-tile roof is 18 years old. Should we re-roof first? | Solar arrays typically have a 25-year production warranty; if your roof has fewer than 7-10 years of remaining life it usually makes sense to re-roof first to avoid R&R (remove and reinstall) the array later, which costs $2,000-$5,000+ depending on system size. Spanish tile complicates the math: tile-hook attachments are well-understood but tile breakage during install runs 3-7 percent, and re-roofing tile is expensive. We assess at the site visit, share the math on re-roof first versus install now, and let you decide. | Old roofs are fine; we'll work around it. |
| Do older LA Craftsman and Spanish homes need a structural review for the array attachment? | Often yes. Older LA single-family homes (1920s-1950s Craftsman, Spanish, mid-century) may have rafter dimensions or spacing that fall outside SolarAPP+'s standard structural assumptions. LADBS may require a stamped structural engineering review with PSI-tested tie-down details. We assess at the site visit, identify whether structural is required, and itemize the engineering scope separately. We do not bury structural fees in the array price. | Old homes never need a structural review; the panels are light. |
| Our home is in the LA hills WUI zone. How does CRC R337 affect the array layout? | For homes in CAL FIRE Very High FHSZ (Hollywood Hills, Brentwood, Bel Air, Pacific Palisades, Topanga, etc.), CRC R337 governs wildfire-resistant construction. The array layout follows California Fire Code roof-access pathway requirements: a 3-foot setback at ridges and a 3-foot pathway from the eave on a residential roof, with specific exemptions for steep slopes. The panels themselves are Class A fire-rated; conduit penetrations use fire-rated boots; combiner boxes near eaves need ignition-resistant placement. We document the FHSZ designation, the setbacks, and the rated hardware in the permit drawings. | Fire rules do not change solar installs in LA. |
| How does the LA seismic environment affect array mounting and racking choice? | The LA seismic design category is high (Sds in the 1.0-1.5g range for most of the basin). Racking manufacturers publish seismic certifications (UL 2703 plus IBC engineering); we select racking with the appropriate seismic rating, set attachment density per the manufacturer engineering for your rafter geometry, and document the structural calculations in the permit set. Composition-shingle attachments use lag screws into rafters; tile-roof uses tile-hooks with rafter-pinned baseplates. We do not use spec-only fasteners or shortcut attachments. | Seismic does not matter for solar; the array is light. |
| Which inverter topology do you recommend for our LA install: microinverter or string? | Common choices: Enphase IQ8 microinverters (panel-level MPPT, rapid shutdown built-in, 25-year warranty, easier later expansion, premium price), or SolarEdge string inverter with power optimizers (panel-level optimization at lower per-watt price than micros, 12-year inverter warranty extendable to 20-25). For complex LA roofs (multiple orientations, partial shade from neighbor trees, dormer geometry on Spanish or Craftsman roofs) microinverters typically win. For simple single-azimuth large roofs, SolarEdge string usually has the better $/W. We model both and share the cost-benefit. Federal 25D being expired does not change which topology is right; the math now favors slightly lower-cost topologies. | Microinverters are always better; that is the only option. |
| Our home is in a canyon with mature trees. How do you handle shading in the production model? | We do a 3D shading analysis using HelioScope or Aurora with on-site measurements (Suneye or similar) for trees and adjacent structures. Hollywood Hills, Beachwood Canyon, Topanga, and many San Gabriel Foothills properties have meaningful winter shading from mature oaks, eucalyptus, or neighbor structures. The model shows per-month derate and which roof faces are affected. If panel-level mismatch is severe we recommend microinverters or optimizers; if shading is heavy on one face we re-scope the array. We share the shading inputs and the production output. | Shading is fine; modern panels handle it. |
| How do NEC 690 and 705 affect the design and how is rapid shutdown handled? | NEC 690 governs PV system design (conductor sizing, overcurrent protection, equipment listing); NEC 705 governs interconnection (the 120 percent busbar rule for back-fed inverter breakers). For a typical LA install on a 200A panel with a 40A back-fed inverter breaker, we verify 200 + 40 = 240A is under 120 percent of 200 = 240A (right at the limit; we document the calc). Rapid shutdown follows NEC 690.12 with module-level shutdown at the panel for Enphase or SolarEdge platforms. We document the calc, the rapid-shutdown method, and the labeling per NEC 690.56 in the permit set. | NEC compliance is the inspector's problem. |
| What monitoring and commissioning do we get at the end of the install? | Monitoring is the Enphase Enlighten app (panel-level), SolarEdge mySolarEdge (string + optimizer-level), or the inverter manufacturer's platform. We register your account, set up alerts for production faults or under-performance, and confirm the gateway communicates with the cloud before leaving. The commissioning report includes the as-built single-line diagram, the actual production at sunrise / midday / sunset on a clear day, the inverter firmware version, and the LADWP PTO confirmation. We share the report. | Monitoring is optional; you can set it up yourself. |
| What is the warranty stack for the panels, inverter, racking, and labor? | Typical warranties: panels 25 years (production guarantee, declining linearly to ~85 percent of nameplate), microinverters 25 years (Enphase IQ8) or string inverters 12 years extendable to 20-25 (SolarEdge), racking 20 years (UL 2703 platforms), labor 5-10 years (varies by installer). We list each warranty line in the proposal: who provides it, what triggers it, what is excluded (typically acts of God, vandalism, salt-air corrosion in some warranties). We register on your behalf and share confirmation. | Warranties are all 25 years; do not worry about the details. |
| We are planning a heat pump and EV charger in the next 2 years. Should we oversize the array now? | Probably yes. Adding heat pump HVAC, HPWH, and EV charging typically grows annual load by 4,000-8,000 kWh; sizing the array for that future load now costs slightly more incrementally and avoids a second LADBS permit cycle plus a second LADWP PTO. We use your current 12 months of LADWP bill data plus modeled future loads from Manual J and EV mileage, then size the array to that target. LADWP's net-metering credit is favorable, so slightly oversized arrays generally make financial sense in LA. We share the load model. | Always undersize and add later. |
| If we re-roof and install solar together, who coordinates LADBS permits and warranty? | We coordinate or partner with a roofer on a single project schedule: roof replacement first, then solar mount and electrical, with LADBS issuing separate permits for the roofing (typically Express) and the solar electrical (ePlanLA or SolarAPP+). Warranty handoff matters: the roofer warrants the underlayment and the roofing; we warrant the array attachment and the electrical. We document the boundary in writing so a leak in year 5 has a clear owner. We do not blur the warranty boundary. | We do everything; warranty is one phone call. |
| What is the LADWP solar interconnection application process and fee? | LADWP's interconnection application for residential PV under 30 kW is submitted online via ladwp.com after permit issuance. The application includes the single-line diagram, the inverter spec sheet, the array layout, the Class A roof confirmation if in a WUI zone, and the building permit number. An application fee applies (we list the current LADWP rate at quote time); the interconnection agreement is signed before LADWP authorizes meter-side commissioning. We submit on your behalf, share the application number, and track to PTO. We do not energize the system before PTO. | Just flip the breaker once the inspector signs off; LADWP figures it out. |
| Which circuits will be backed up during an outage, and for how long? | We provide a backup-loads list (refrigerator, internet, lights, HVAC controls, well pump if any), estimate runtime in hours at typical and worst-case usage, and explain whether whole-home or essential-loads backup is recommended. | The battery powers the house. |
| Does my install qualify for SGIP (Self-Generation Incentive Program), and at what tier? | We verify current SGIP budget status before quoting: as of December 31, 2025 the ratepayer-funded General Market, Equity, and Equity Resiliency budgets are closed to new applications, and only the AB 209-funded RSSE (Residential Solar and Storage Equity) tier remains open — and that budget is fully reserved with new applications served via an attrition-based waitlist (selfgenca.com). We document the waitlist position rather than promising a rebate, and we explain that pre-approval is required before equipment is delivered. | SGIP always pays out the maximum amount. |
| What is the battery's usable kWh and continuous inverter power, and how do they relate? | We specify both: kWh determines how long the backup lasts; the inverter's continuous AC output determines what can run at once (refrigerator + lights + maybe HVAC vs everything). | kWh is the only number that matters. |
| Is the battery AC-coupled or DC-coupled with the solar array, and why? | AC-coupled batteries use a separate inverter and are easier to retrofit to existing solar. DC-coupled batteries share an inverter with new solar and are typically more efficient end-to-end. We choose based on whether the solar array is new or existing. | Coupling does not matter. |
| Can we add more battery capacity later, and what are the limits? | Most modern systems support stacking additional units up to a vendor-specified maximum. We document the maximum stack today, what is needed to add capacity later (matching firmware, software update, possible electrical re-work), and whether SGIP can be applied to expansion units. | Buy the biggest battery today; expansion is impossible. |
| What depth-of-discharge limit does the battery use, and how does that affect usable kWh? | We explain the nameplate kWh vs usable kWh: modern LFP batteries reserve very little for cycle life (often 95 to 100 percent of nameplate is usable); older chemistries reserve 10 to 20 percent. We quote usable kWh in the proposal so you can compare like-for-like. | Nameplate kWh is the usable kWh. |
| What is the manufacturer warranty on the battery, and what limits it? | Most residential batteries carry a 10 to 12 year warranty, often paired with a cycle count (e.g. 6,000 to 10,000 cycles) or throughput limit (e.g. 37.8 MWh) - whichever comes first. We provide the spec sheet and explain what voids coverage. | Lifetime warranty; no fine print. |
| Are time-of-use arbitrage cycles counted against the warranty? | Yes. Every charge-discharge cycle counts toward the throughput limit; aggressive daily TOU arbitrage may shorten the years-based warranty window. We model expected cycles per year for your usage pattern. | Cycling does not count against the warranty. |
| How will the battery shift load away from PG&E peak hours? | We program the battery to charge from solar during midday and discharge during the PG&E EV2-A or E-ELEC peak window (typically 4-9pm), saving you the peak-period delta. We tune the schedule for your actual usage and rate plan. | The battery charges and discharges whenever. |
| How does NEM 3.0 change the battery payback? | Under NEM 3.0, export compensation dropped by roughly 75 percent, so self-consumption (using your solar via the battery instead of exporting) is now the primary battery economic driver. We model expected savings under NEM 3.0 with your specific rate plan. | NEM 3.0 has no effect on battery payback. |
| How will the install meet CRC 1207 / R327 fire-setback rules for energy storage? | We design the install per California Residential Code R327 (formerly section 1207): separation from windows, doors, openings into the dwelling, and other batteries; smoke and heat detectors per code; and an exterior wall location where possible. We document compliance in the permit submittal. | Fire setbacks are optional. |
| What is your post-install commissioning checklist? | Commissioning includes verifying battery state-of-charge reporting, testing backup-mode transfer with a simulated outage, walking through the app for backup-only vs TOU modes, and confirming the SGIP system performance metering is functioning if SGIP is part of the project. | We turn it on and leave. |
| Are you an installer certified by the battery manufacturer? | Yes. We provide our certification number for the specific battery brand (Tesla Powerwall, Enphase IQ, LG Chem RESU, FranklinWH, etc.); certification is typically required to preserve full warranty coverage. | Certification does not matter for batteries. |
| Who handles the PG&E interconnection update for the new battery? | We submit the updated PG&E interconnection paperwork to add the battery to your existing or new solar interconnection, and we obtain the updated Permission to Operate before energizing. | PG&E interconnection happens automatically. |
| What panel-side breaker work or interconnection method does the battery require? | We confirm whether the battery interconnects via a back-fed breaker (with sum-of-breakers check per NEC 705.12), a supply-side tap, or a dedicated battery sub-panel; we show the calculation on the permit drawings. | Any spare slot will work. |
| Does SGIP apply for a battery install on LADWP? | Statewide SGIP General Market, Equity, and Equity Resiliency budgets do not apply to LADWP customers; those budgets are CPUC-administered and ratepayer-funded by IOUs (PG&E, SCE, SDG&E, SoCalGas). LADWP runs its own SGIP-equivalent: the Residential Solar and Storage Equity (RSSE, AB 209) program for income-qualified solar plus battery customers, administered through sgip@ladwp.com. As of February 2026 RSSE is fully reserved but accepting waitlist applications. For non-income-qualified LADWP customers there is no comparable statewide-tier general market rebate. We do not promise SGIP payouts that do not apply on LADWP. | Statewide SGIP pays for batteries; sign up after install. |
| Does a battery actually improve payback under LADWP net metering, the way it does on PG&E NEM 3.0? | The economics are different. Under LADWP's near-retail net metering, exported solar already earns close to retail credit, so the self-consumption benefit of a battery is much smaller than under PG&E NEM 3.0 (where exports earn roughly 75 percent less). The case for a battery in LA is more about backup resilience (Santa Ana wind events, PSPS in some hillside neighborhoods, planned LADWP outages for system work) than about bill arbitrage. We model both bill impact and outage resilience and let you decide. We do not pretend the bill savings justify the battery; that math is honest on PG&E and weaker on LADWP. | Adding a battery always cuts your LADWP bill in half. |
| What backup loads should we plan for in an LA outage? | Typical LA residential backup-loads: refrigerator (continuous 100-200W average, 800W startup), interior lighting (LED 50-150W total), Wi-Fi and router (20-30W), TV plus AV (100-200W), phone and laptop charging (50W), and during summer at least one window or mini-split for cooling load (a 1-ton mini-split runs 800-1500W). For Santa Ana wind events or planned LADWP outages running 6-12 hours, a 13.5 kWh battery covers everyday backup; for 24-hour outages with cooling we typically recommend 27 kWh or solar plus battery to recharge mid-day. We size from your specific list, not a generic load. | 13.5 kWh works for everyone in LA. |
| Our wall-mount battery is heavy. How is it seismically anchored in our LA Spanish house? | A Tesla Powerwall 3 weighs about 290 pounds; Enphase IQ Battery 5P weighs about 165 pounds; FranklinWH aPower 2 is about 350 pounds. CBC seismic detailing requires anchoring to structural framing (wood studs, masonry, or concrete) using the manufacturer's published seismic anchor schedule. For LA Spanish stucco-on-wood we drill through stucco into studs with the manufacturer's specified lag size and pattern; for masonry walls we use expansion anchors rated for the seismic load. We include the structural detail in the LADBS permit set. We do not anchor to drywall. | Just hang it on the wall; the wall holds. |
| Our home is on a Hollywood Hills WUI lot. Does CRC R327 affect where the battery goes? | Yes, multiple rules interact. CRC R327 (statewide ESS rules) requires battery siting setbacks from openings, exit pathways, and combustible construction; CRC R337 (WUI zones) adds wildfire-rated construction requirements for adjacent assemblies. Garage installs adjacent to a habitable space need fire-rated separation. Outdoor wall mounts on WUI lots need ignition-resistant placement. We verify the FHSZ designation, walk through the setback measurements on-site, and document everything in the permit set. We do not install the battery in a marginal location and hope it passes inspection. | Just bolt it to the wall; LADBS does not check ESS setbacks closely. |
| Can the battery shift LADWP TOU-charged loads to save on the bill? | For LADWP R-1B TOU customers, a battery can charge during the Base period (8pm-10am weekdays, all weekend) and discharge during High Peak (weekdays 1pm-5pm) and Low Peak (10am-1pm and 5pm-8pm) windows. The arbitrage value is the rate spread between Base and High Peak. We model this against your usage and share the year-1 estimate. For most LA residential homes the arbitrage value is modest (typically a few dollars per month per kWh of battery capacity) because LADWP rate spreads are narrower than PG&E TOU spreads. The case is still primarily resilience, not arbitrage. | Battery pays for itself in 2 years on LADWP TOU. |
| Should we back up the whole house or use a critical-loads sub-panel? | Three options: whole-house backup (battery and inverter sized to carry total connected load including AC compressors and EV charging during outage, more expensive), critical-loads sub-panel (a separate sub-panel with only essential circuits backed up, lower battery capacity needed), or smart-panel-style load management (Span, Lumin, or Schneider Square D Energy Center that disable non-critical loads automatically during outage). For LA homes with central AC, whole-house typically requires 2-3 batteries; critical-loads with a smart-panel typically works with one. We model each and share the cost-benefit. | Whole-house backup is always the right answer. |
| Which battery brands do you install in LA and what are the tradeoffs? | Common 2026 LA installs: Tesla Powerwall 3 (13.5 kWh usable, integrated inverter, supports up to 4 units, AC-coupled with optional DC), Enphase IQ Battery 5P (5 kWh per unit, modular, AC-coupled, pairs with IQ8 microinverters), FranklinWH aPower 2 (15 kWh usable, integrated, often less expensive per kWh), LG Energy Solution RESU PRIME (DC-coupled, paired with compatible inverter). We compare on: usable capacity per dollar, warranty terms (cycles plus throughput), local service availability in LA, monitoring app quality, and compatibility with your existing or planned solar inverter. We do not push one brand; we share the comparison. | Tesla Powerwall is the only option worth considering. |
| Should the battery be AC-coupled or DC-coupled to the solar? | AC-coupled (Tesla Powerwall 3, Enphase 5P, FranklinWH) has its own integrated inverter, works with any existing solar inverter, and is the typical retrofit path. DC-coupled (LG RESU PRIME with SolarEdge or Sol-Ark hybrid inverter) shares the solar inverter and is slightly more efficient when round-tripping solar through the battery, useful for new solar plus battery installs being designed together. For a retrofit on existing solar, AC-coupled almost always wins on cost and simplicity. For a new install, we model both. We document the topology choice and the inverter compatibility in the proposal. | DC-coupled is always the right choice. |
| What UL certifications matter and why? | UL 9540 covers ESS as a system (battery plus inverter plus controls); UL 9540A is the thermal-runaway propagation test that verifies a single-cell failure does not cascade into adjacent units. For LA installs (CRC R327 plus CFC requirements) UL 9540 listing is required and UL 9540A test data informs the setback distances in the permit. We list both certifications in the proposal and provide the cell-pack test data when LADBS requests it for hillside or attached-garage installs. We do not install non-listed equipment. | UL listing is just a sticker; nobody checks. |
| What battery warranty terms should we look at? | Battery warranties have three dimensions: years (typically 10), cycles (typically 5,000-10,000), and throughput (typically 27-40 MWh total energy passed through). Whichever limit is hit first ends the warranty. Tesla Powerwall 3 is 10 years and unlimited cycles for daily use, 70 percent capacity retention; Enphase IQ Battery 5P is 15 years and 6,000 cycles, 60 percent retention; FranklinWH aPower 2 is 15 years and 12,000 cycles. We list each warranty's three dimensions in the proposal, register on your behalf, and share confirmation. We do not let 'warranty' marketing copy substitute for the actual terms. | Warranty is 10 years; that's all you need to know. |
| What monitoring and commissioning do we get? | Monitoring is the brand app (Tesla app, Enphase Enlighten, FranklinWH app, etc.). We register your account, set up outage and low-SOC alerts, confirm the gateway communicates with the cloud, and walk through the app together. Commissioning includes a backup-test (simulate grid outage by opening the main breaker, confirm battery picks up critical loads within the inverter's transfer time, typically 200-500 ms), state-of-charge verification, and a signed commissioning sheet with measured values. Without commissioning the battery may not transfer cleanly during a real outage. The LADBS inspection card is separate from the commissioning sheet. | Push the button at the end; you don't need a backup test. |
| Can a battery work with LADWP Virtual Net Metering on a multifamily property? | LADWP Virtual Net Metering for multifamily property covers the solar export allocation across tenant meters. Adding a battery to a VNM-property complicates the interconnection: the battery's discharge timing affects which meter sees the credit. We confirm LADWP's current VNM-plus-storage rules at quote time (the program has been evolving) and document the configuration. For most single-family LA homes this is not a question; for duplex / triplex / fourplex property owners adding both solar and battery, we walk through the metering implications carefully. | VNM plus battery just works; LADWP figures it out. |
Questions for electricians
| Question | Good response | Bad response |
|---|---|---|
| What is my panel size and service size, and is it adequate for adding a heat pump? | We inspect the panel labels and main breaker on site, explain whether 100A, 125A, 150A, or 200A is adequate, and verify the service drop matches the panel. | We guess from a photo only; no on-site inspection. |
| Can we avoid a service upgrade by using smart load management? | Possibly. We will perform a formal Article 220 load calculation, propose smart load management for HVAC + EV + water heater coordination, and explain the tradeoff vs upgrading. | You always need 200A; no calculation needed. |
| Will the heat pump need a new dedicated circuit, and what breaker size? | Yes, the outdoor unit and air handler each typically need dedicated circuits at the breaker sizes the manufacturer specifies (often 30-50A for outdoor, 15-30A for indoor). | Any spare breaker will work. |
| Our older LA home has a 100A panel. Will it accept the heat pump? | A typical 3-4 ton heat pump needs a 30-50A 240V circuit. Whether a 100A panel handles the new circuit depends on your existing NEC 220 load calc: connected loads minus diversity, range, dryer, water heater, lighting, plus the new HP. If the calc shows the panel is at or over its rated capacity we have three paths: a panel upgrade to 200A through LADBS plus LADWP service-conductor coordination, an NEC 750 load management device that throttles the HP during peak draw to fit the existing panel, or a smart-meter-class energy-monitoring approach. We run the NEC 220 calc, share it, and present the options with costs. | 100A is fine; just install the breaker. |
| Does the install require a dedicated electrical circuit, and what size? | Standard heat pump water heaters typically need a dedicated 30A 240V circuit; some 120V hybrid models can operate on a 15A or 20A circuit at reduced capacity. We size the circuit per the manufacturer's data plate and document conductor gauge and breaker rating in the quote. | Share the circuit with the dishwasher. |
| What electrical circuit does the HPWH need and how does that affect our older LA panel? | Standard 240V HPWH installs use a 30A 240V dedicated circuit (Rheem ProTerra, A.O. Smith Voltex AL, Bradford White AeroTherm, Stiebel Eltron Accelera 300). For 100A LA panels we run an NEC 220 load calc; if the panel is tight, three paths: panel upgrade to 200A through LADBS plus LADWP service-side coordination, NEC 750 load management to fit existing panel, or the 120V plug-in hybrid HPWH variant (Rheem ProTerra Plug-In) which uses a standard 120V circuit and may avoid a panel upgrade entirely. The 120V variant is slower-recovery but a real option. We share the load calc and the options. | Just add the 240V circuit; the panel will handle it. |
| What charger amperage do you recommend, and why? | We size the charger based on your vehicle, expected daily mileage, panel capacity, and future second-EV plans (typically 32-48A continuous draw on a 40-60A circuit). | Always install the biggest charger; bigger is better. |
| Will the charger need a dedicated 240V circuit? | Yes. We run a dedicated 240V circuit sized at 125 percent of the charger's continuous draw, with the correct conductor gauge and conduit per code. | Share a circuit with the dryer. |
| How will you confirm my panel has capacity for the charger? | We perform an Article 220 load calculation on site, consider existing loads and planned heat pump or HVAC additions, and explain whether smart load management can avoid a service upgrade. | Your panel is fine; no calculation needed. |
| Can smart load management let me add a charger without upgrading the panel? | Often yes. Devices like Span panels or charger-side load-share modules may avoid a service upgrade by throttling the charger when other loads (HVAC, water heater) are active. | Load management is unreliable; always upgrade the panel. |
| How would you support a second EV without re-wiring everything later? | We may install a load-sharing charger today, or pre-pull conductors for a second circuit. We document the planned future load in the Article 220 calc. | One charger is plenty for any household. |
| How will you handle grounding and bonding for the new circuit? | We verify the service ground meets code, bond the charger neutral and equipment per Article 250, and confirm the GFCI protection (built in or required separately). | Grounding is standard; nothing to discuss. |
| Where will the conduit run, and what does it cost to extend? | We walk the routing on site (interior wall vs exterior, attic vs trench), specify conduit fill code requirements, and itemize incremental cost per linear foot. | Conduit routing is included; don't worry about it. |
| What labor warranty do you provide on the install, separate from the manufacturer warranty? | We provide a 1-2 year labor warranty on installation; the manufacturer warranty (typically 3-5 years on the charger) is separate. | Lifetime warranty on everything. |
| Should we install a dedicated LADWP EV meter and move to TOU-EV pricing? | LADWP's dedicated EV meter is a separately metered service for the EVSE circuit, billed on an EV-specific rate (the R-1B TOU plan applied to the EV circuit). It carries the $250 Charge Up LA adder. The trade is: separate service charge for the second meter versus EV-specific pricing on only the EV load. We model both options against your charging pattern: dedicated EV meter versus whole-home TOU. Dedicated EV meter usually wins if your annual EV charging is over 4,000-5,000 kWh and you do not want to move whole-home to TOU. We share the model. | Dedicated EV meter always saves money. |
| How do you size the EV circuit given we may add a heat pump and HPWH later? | We run an NEC 220 load calc that adds the EV circuit (continuous 125 percent of nameplate, so a 40A EVSE counts as 50A continuous), plus the future HP HVAC (estimate 30-50A 240V), plus a future HPWH (typically 30A 240V), plus existing range, dryer, and lighting loads with NEC diversity factors. We share the worksheet. If the total exceeds your panel rating, we discuss three paths: panel upgrade to 200A through LADBS plus LADWP service-side coordination, NEC 750 load management to fit existing panel, or oversized service entrance now to avoid later rework. The decision is yours; we present costs for each. | We don't need to load-calc for one EV circuit. |
| Which smart EVSE models do you recommend and why for an LA install? | Common choices for LA installs: Wallbox Pulsar Plus (40A, Wi-Fi, OCPP-capable), ChargePoint Home Flex (50A, Wi-Fi, public-network integration), Tesla Universal Wall Connector (48A, Tesla and J1772-compatible via included adapter), Emporia EV Charger (48A, energy-monitoring), and Enphase IQ EV chargers (integrates with Enphase solar / battery if you have it). For LADWP Charge Up LA eligibility, the unit must appear on LADWP's qualifying products list; we confirm before order. We do not lock you into one brand; we walk through tradeoffs in price, scheduling flexibility, OCPP support for future demand-response, and warranty. | All chargers are the same; pick the cheapest. |
| Our LA condo or duplex has shared parking, no private garage. What are the install paths? | For shared parking we assess three paths: a tenant-installed EVSE on the dedicated parking stall (requires HOA or landlord written approval plus an LADBS electrical permit pulled by the property owner or with their authorization), a shared LADWP EV-charging-station rebate (if the property is a multifamily site, LADWP has multi-unit pathways), or Level 1 home charging plus access to public DC fast-chargers on the LADWP Charge Network. We do not promise a curbside drop; that requires LADOT or LA Bureau of Engineering review and is not a homeowner-led project. We document the path and what needs to happen. | Just run an extension cord from the unit. |
| What does NEC Article 625 require for the EV charger circuit? | NEC 625 governs electric vehicle power transfer systems. Key requirements: the branch circuit must be sized at 125 percent of the EVSE nameplate continuous rating (so a 40A EVSE needs a 50A breaker plus #6 copper conductor minimum), GFCI or equivalent personnel protection is required for cord-and-plug 240V receptacles, the disconnecting means must be within sight of the EVSE for some installs, and the EVSE must be listed (UL 2202 / UL 2594). We follow 625 and document the breaker size, conductor gauge, GFCI provision, and disconnect detail in the permit set. | EVSE circuits follow the same rules as a dryer; no special code. |
| Our LADWP panel is in the back of the house and the parking is at the front. Does that change wire sizing? | For long runs (over 100 feet) voltage drop dominates: NEC recommends keeping total branch-circuit voltage drop under 3 percent. A 40A EVSE on #6 copper, 240V, drops about 1.7 percent at 100 feet but pushes 3 percent at 175-200 feet; for very long runs we upsize to #4 or #2 copper. The proposal lists the conductor gauge, the calculated voltage drop at your run length, and the breaker size. Hidden voltage-drop derating is a common quote omission; we put it on the page. | Wire size is wire size; 100 feet is the same as 10 feet. |
| How is the EVSE grounded and bonded back to the LADWP service? | The EVSE branch circuit is bonded to the existing equipment grounding system at the panel, which is bonded to the LADWP service neutral and to the building's grounding electrode system (NEC 250). Older LA homes sometimes have inadequate or corroded grounding electrodes; we verify the GEC continuity and supplement with a ground rod or chemical electrode if needed. We document the grounding configuration. A poorly grounded EVSE can trip nuisance GFCI faults and is a real safety concern. | Old homes are fine; the building has been grounded forever. |
| What warranty applies to the EVSE and to the install labor? | EVSE manufacturer warranties typically run 3 years (Wallbox) to 5 years (ChargePoint Home Flex) to 4 years (Tesla Universal Wall Connector); some manufacturers extend to 10 years if you register and the install is by an authorized installer. We register on your behalf and share the confirmation. Install labor warranty varies by contractor; we list our labor warranty length (typically 1-2 years) in the proposal. Hidden behind 'lifetime warranty' marketing language often is: lifetime parts but 90-day labor; we read the fine print and call it out. | Warranty is on the box; do not worry about it. |
| If we add solar plus battery later, should we oversize conduit or otherwise prepare now? | Yes, typically. Running a single 1.5 inch or 2 inch conduit between the EVSE location and the panel during the EV install costs a fraction of a separate rework later. The conduit accepts future solar PV string conductors, battery DC bus, or a future load-managed sub-panel. We size for the LADWP Solar Rooftops program eligibility (when that program reopens its application backlog) and for LADWP's NEM program. We note this as an optional adder in the proposal so you can decide. | Oversized conduit is wasted money; never need it. |
| How do you mount the EVSE so it survives an earthquake? | California Building Code seismic detailing applies to wall-mounted electrical equipment. We mount the EVSE to wall studs (not drywall anchors alone) using the manufacturer's seismic anchor schedule where provided; for masonry or stucco walls we use expansion anchors rated for the unit weight and the LA seismic design category. The conduit between EVSE and panel uses flexible whip at the connection to absorb seismic movement. We document the anchor schedule and the flexible connection in the permit set. | Just screw it to the wall; it's not that heavy. |
| How do NEC 706 and 705 apply to the battery interconnection? | NEC Article 706 covers ESS installations (disconnects, overcurrent protection, signage, working clearances). NEC 705.12 covers parallel-source interconnection: for a battery plus solar plus utility on the same busbar, we verify the 120 percent busbar rule, or use a supply-side tap if 120 percent fails. For LADWP service, the disconnect must be accessible to the utility and labeled per LADWP service-rule conventions. We document each NEC citation in the permit set. We do not short-circuit the calc to make it 'fit'. | NEC compliance is the inspector's problem. |
| How do you handle grounding for the battery in an older LA house? | NEC Article 250 requires the ESS to be bonded to the existing grounding electrode system. Older LA Spanish, Craftsman, and bungalow homes sometimes have only a single ground rod, an undersized water-pipe bond, or both; the existing system may not meet current code for a new ESS. We measure the existing grounding electrode resistance, document compliance, and add supplemental electrodes (typically a second 8-foot copper-clad rod 6 feet from the first) if required. We include the grounding work as a line item in the proposal. | Just bond it to the panel; that's enough. |
| Will you perform an NEC Article 220 load calculation before sizing the new panel or service? | Yes. We total existing connected loads, apply Article 220 demand factors, then add expected future loads (heat pump HVAC, heat pump water heater, EV charger, induction range, battery) before recommending a service size. | We size from the existing panel rating. |
| Is this a service upgrade or a panel-only replacement, and how do you decide? | We explain the difference plainly: a service upgrade changes the service drop, meter, and main breaker rating (utility coordination required); a panel-only replacement swaps the breaker box at the existing service rating. We base the recommendation on the Article 220 result, not on a default upsell. | It is the same thing. |
| Who coordinates with the utility for the service upgrade, and what lead time should we expect? | We coordinate with the serving utility (your investor-owned utility such as PG&E, SCE, or SDG&E, or your municipal utility such as LADWP or SMUD) for the service drop, meter swap, and any utility-side work. We document the expected utility lead time in the quote because it often dominates the project schedule. | The utility handles itself. |
| How do you decide between 200A, 225A, or 320A service, and how much headroom should we plan for? | We size to the Article 220 calculated demand plus headroom for the ten-year horizon of electrification projects already on the table. For most California single-family homes adding heat pump HVAC, heat pump water heater, and one or two EVs, a properly sized 200A service is enough; 225A or 320A is only justified when the load calc shows it. | Bigger is always better, so we go 320A. |
| When does a smart panel (Span, Lumin, Eaton EV Choice) make sense versus a standard load center? | A smart panel can avoid a service upgrade when load shedding can keep peak demand under the existing service rating, or when granular per-circuit metering is desired. A standard load center is the right choice when the Article 220 result already fits the service rating, the homeowner does not want app-based controls, or budget is tight. | Smart panels are always the answer. |
| Is a sub-panel addition (for a detached garage, ADU, or workshop) a viable alternative to a full service upgrade? | A sub-panel can serve outbuilding loads without changing the main service rating when the Article 220 calc shows the existing service still has capacity. We size the sub-panel feeder per NEC and run it under permit. | Sub-panels always require a service upgrade. |
| Will you inspect and update the grounding electrode system as part of the panel work? | Yes. We verify the grounding electrode system (ground rods, water-pipe bond, concrete-encased electrode where present), measure resistance where required, and upgrade conductors and connections to the current code edition adopted by your jurisdiction. | Grounding is fine if the panel is bonded. |
| Which circuits in the new panel will require AFCI or GFCI protection, and what code edition are you applying? | We apply the California Electrical Code edition currently adopted by your local AHJ (the California Electrical Code is based on the NEC with California amendments). We itemize AFCI-required and GFCI-required circuits and price the AFCI/GFCI breakers separately so the homeowner sees the cost driver. | AFCI rules are confusing, so we skip them. |
| Will the quote include whole-home surge protection, and which type? | We recommend a Type 2 surge protective device (SPD) integrated with the new panel as a standard line item; Type 1 SPD at the service entrance is an upgrade option for homes with frequent utility-side transients. We explain warranty terms and replacement procedure after a major surge event. | Surge protection is unnecessary. |
| Does the existing panel location meet current code clearances, or do we need to relocate it? | We measure NEC Article 110 working-clearance requirements (depth in front of the panel, clear width, headroom) and confirm the panel is not behind cabinets, in clothes closets, or in other prohibited locations. If the location does not meet current code, we quote the relocation. | The existing spot is fine because the old panel fit. |
| Will you use conduit or NM cable for the new circuits, and how do you decide? | We follow the California Electrical Code wiring methods permitted for residential occupancies. Conduit is required for exterior runs and where physical damage is likely; NM cable is permitted in many concealed interior runs. We size conductors for the future load, not just today's circuit. | Whatever is easiest and cheapest. |
| Who pulls the electrical permit at the local AHJ (city or county permit center), and is the fee itemized in your quote? | We pull the electrical permit at the local AHJ in our own name, attend the inspection, and itemize the permit fee in the quote. We do not ask the homeowner to pull the permit. | We do not pull permits because they slow the job. |
| Walk us through the inspection process: which inspections are required and what does each one check? | We typically schedule a rough-in inspection (panel mounted, grounding electrode system verified, conductors run) and a final inspection (devices terminated, AFCI/GFCI verified under test, labeling complete). The exact sequence depends on the local AHJ. | There is just one inspection at the end. |
| How long will the home be without power during the panel swap, and what time of day will it occur? | A panel-only swap typically takes 6 to 10 hours; a service upgrade with meter swap can take a full day and is constrained by the utility's window. We confirm the exact window and time-of-day with the utility before scheduling. | Will not take long. |
| Will the new panel be sized and labeled for future solar or battery interconnection per NEC Article 705.12? | Yes. We size the busbar and main breaker so the future solar PV and battery interconnection meets NEC Article 705.12 (the 120% rule or supply-side connection, depending on the configuration). We document the headroom available so the future installer can verify quickly. | Solar and battery do not affect panel sizing. |
| If we may add a generator interlock or transfer switch later, what should the new panel design account for? | We can include a generator interlock kit with the panel install, or pre-wire space for a future automatic transfer switch. Interlock is the lowest-cost option for occasional backup; ATS is the right path for whole-home automatic backup. | Generator readiness is a future problem. |
| How are you treating the federal §25C tax credit for panel-upgrade work? | The federal §25C Energy Efficient Home Improvement Credit expired December 31, 2025 under OBBBA (PL 119-21). For panel work performed in 2026 and later, we do not list §25C as an applicable credit and we will not claim eligibility. | You qualify for the 30 percent federal tax credit on panel work. |
| Is panel-upgrade work eligible for HEEHRA (Home Electrification and Appliance Rebates) in California, and what is the current funding status? | Panel-upgrade work, sub-panel additions, and electrical wiring needed to support qualifying electrification projects can be eligible HEEHRA expenses for income-qualified households. CPUC reported HEEHRA funds fully reserved earlier this year, so we do not promise current availability and confirm against the CPUC HEEHRA portal at quote time. | HEEHRA covers all panel upgrades automatically. |
| Are there TECH Clean California, CCA (Community Choice Aggregator), or utility-side incentives that apply to this panel work? | TECH Clean California is statewide for qualifying heat-pump installations; panel-upgrade work tied to a qualifying heat pump may be eligible. Many CCAs (such as MCE, SVCE, CleanPowerSF, SJCE) and IOUs run their own electrification rebates with panel-work eligibility. We confirm the program rules in writing before the quote and list each program with its reservation status. | All rebates are guaranteed if you sign today. |
| What is the manufacturer warranty on the new panel, breakers, and any smart-panel hardware? | We list the manufacturer warranty for the panel and main breaker (typically 10 years), branch-circuit breakers (typically 1 to 10 years), and smart-panel hardware separately. We explain what voids each. | Warranty is whatever the box says. |
| What is your labor warranty on the panel installation, and does it cover related troubleshooting? | We offer a written labor warranty (typically 1 to 5 years) covering workmanship on terminations, conduit runs, and grounding work. We explain what is covered and what is not. | Our work is good, no warranty needed. |
| Based on the Article 220 result, what do you recommend as the best next action and why? | We propose a single recommended option with the load-calc rationale, list one alternative with the cost delta, and explain what would change our recommendation. We are clear about which costs are firm and which depend on the utility or AHJ. | Whatever you want is fine. |
General questions for every contractor
| Question | Good response | Bad response |
|---|---|---|
| Can you separate confirmed incentives from assumed incentives in the quote? | Yes. We mark each incentive as confirmed (with program ID and current reservation status) versus assumed (subject to verification before contract). | All listed incentives are yours. |
| Does the federal Section 25C tax credit apply to my installation? | Section 25C expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Installations completed in 2026 or later do not qualify for §25C. | You'll get the federal credit on your taxes. |
| Are BayREN Home+ rebates available for this installation? | BayREN Home+ may apply for Bay Area homeowners; we verify the program is currently funded and that the equipment qualifies before submitting. | BayREN always pays out automatically. |
| What is the equipment and labor warranty, and what voids it? | We provide the manufacturer warranty (typically 10 years parts when registered) plus our labor warranty (1-2 years standard); we explain what voids coverage including improper electrical, missing filters, and skipped annual service. | The warranty covers everything forever. |
| What is the best next step before signing a contract? | Schedule a site visit and Manual J load calculation, get a written quote with line-item pricing, verify all incentive reservation requirements, and confirm permit handling. | Sign today to lock in pricing before incentives expire. |
| Our address is in the City of LA on LADWP, not SCE. How does that change the rebate and rate-plan picture for a heat pump? | LADWP is a municipal utility, separate from the IOU stack (PG&E, SCE, SDG&E). That means LADWP runs its own Consumer Rebate Program for HP HVAC, its own EV charger rebate (Charge Up LA), and its own SGIP-equivalent for storage via the LADWP RSSE budget. NEM 3.0 does not apply on LADWP; LADWP runs its own net metering. We verify your meter is on LADWP versus SCE before writing the proposal, because LA County addresses split between LADWP, SCE plus CPA, and a few city-owned utilities (Pasadena Water and Power, Glendale Water and Power, Burbank Water and Power). The rebate stack changes accordingly. | All California utilities work the same. |
| What does the LADWP Consumer Rebate Program pay for a heat pump HVAC install in 2026? | The LADWP Consumer Rebate Program offers up to $2,500 per ton for qualifying central, split, mini-split, or multi-split heat pump HVAC systems, with the rebate amount tied to system type (ducted versus ductless) and to SEER2 / HSPF2 efficiency tiers. Applications must be postmarked within 12 months of purchase, the meter must be active on LADWP, and funding is limited (rebates are not promised). We reserve, document the reservation amount in the proposal, and confirm the tier before equipment is ordered. We confirm via ladwp.com/crp. | LADWP automatically gives you $2,500 per ton. |
| Who pulls the LADBS mechanical and electrical permits and how do I see them? | We pull the mechanical permit at LADBS through ePlanLA or PermitLA (ladbs.org), plus a separate electrical permit if the new circuit requires it. Many residential HP HVAC swaps qualify for the LADBS Express Permit route when the equipment is like-for-like in capacity and no structural change is required; we use Express Permit when eligible. You receive the permit numbers, application copies, the inspection schedule, and final card sign-offs. Permit fees are itemized in the proposal, not bundled into labor. Note the General Plan Maintenance Surcharge increases from 7 to 10 percent effective June 9, 2026, which slightly raises plan-check fees; we use current rates. | LADBS rarely inspects HVAC swaps; we skip the permit. |
| Does the SCAQMD Rule 1146.2 zero-emission rule affect a residential heat pump install? | SCAQMD Rule 1146.2 (adopted June 2024) covers water heaters and boilers rated 75,000 to 2 million BTU/hr (small commercial boilers, large water heaters in multifamily, all tankless), with first compliance dates beginning January 1, 2026. The rule does not apply to residential furnaces of any size, and does not apply to most residential storage water heaters with tanks. For a single-family heat pump HVAC replacement in LA, 1146.2 does not gate the choice. We document the rule citation in the proposal so you can verify; for a separate water-heater scope we revisit applicability for tankless units. | SCAQMD bans gas furnaces statewide. |
| Does adding a heat pump push us onto an LADWP TOU rate plan? | Adding a heat pump does not by itself move you to TOU. LADWP residential TOU options exist (the R-1B TOU plan in particular) with High Peak weekdays 1pm-5pm, Low Peak 10am-1pm plus 5pm-8pm, and Base period 8pm-10am plus all weekend; summer rates apply June through September. The choice depends on your usage shape. We model your 12 months of LADWP bill data on TOU versus the default tier and share the comparison so you can choose. Switching is a customer-initiated request to LADWP. Note LADWP's 2026 rates rose roughly 2.475 cents per kWh versus 2025 for the January-March band, so the model uses current numbers. | TOU is always cheaper if you have a heat pump. |
| We just moved from Glendale to LA. Are we on the same utility? | No, very likely not. Glendale Water and Power is a separate municipal utility from LADWP; Pasadena Water and Power and Burbank Water and Power are also separate municipals. SCE plus Clean Power Alliance covers most LA County unincorporated areas and several incorporated cities (Rolling Hills Estates, South Pasadena, others). The City of LA proper is LADWP. The rebate stack, rate plans, and net-metering rules differ on each. We verify by pulling a recent utility bill and reading the meter service before quoting. | Same county means same utility. |
| Should I expect the federal 25C credit on this heat pump? | The federal Energy Efficient Home Improvement Credit (Section 25C) expired December 31, 2025 under the One Big Beautiful Bill Act (OBBBA, PL 119-21). Installations placed in service in 2026 or later are not eligible. We list the credit as expired in the proposal and do not deduct it from your project cost. If the system was placed in service before December 31, 2025 it may apply; we document the placed-in-service date. | 25C still applies; we deduct it from your quote. |
| What about HEEHRA and TECH Clean California for heat pumps in LA? | Both are statewide California programs that apply to LA addresses regardless of utility. HEEHRA (the federal IRA HOMES rebate, administered by the California Energy Commission) was fully reserved as of February 24, 2026; new applicants are waitlisted with no committed timeline. TECH Clean California was fully reserved on November 14, 2025. We list both at current reservation status (pending or waitlisted), not as confirmed savings, in the proposal. The LADWP Consumer Rebate Program is the active path for LA HP HVAC in 2026. | HEEHRA covers the whole project; just submit after install. |
| Does HEEHRA currently offer a rebate for heat pump water heaters? | Heat pump water heaters are a HEEHRA-eligible category statewide; CPUC reservations for HEEHRA were fully subscribed as of February 2026. We verify current status at energy.ca.gov and may mark HEEHRA as assumed until a reservation is confirmed. | HEEHRA pays out automatically for every install. |
| Does the unit qualify for TECH Clean California, and what is the current status? | TECH Clean California covers qualifying heat pump water heaters statewide; we verify current scope, eligible model lists, and per-unit incentive amount at techcleanca.com before citing a number in the quote. | TECH covers every model on the market. |
| Does the BayREN Home+ program offer a rebate path for heat pump water heaters? | BayREN Home+ has historically offered a heat pump water heater rebate for Bay Area homeowners. We verify current program scope and rebate amount at bayrenhomes.org before submitting. | BayREN funds every Bay Area install at the same amount. |
| Does the federal Section 25C credit apply to the install? | Section 25C expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Heat pump water heater installations completed in 2026 or later do not qualify for the §25C federal tax credit. | The federal credit applies as long as you install before tax day. |
| Who coordinates the plumber and electrician — your team or me? | We coordinate plumber and electrician scheduling under a single project lead, sequence the work so electrical and plumbing don't conflict, and present a unified quote with both trades line-itemed. | You hire and coordinate the electrician separately. |
| Will the quote separate confirmed incentives from assumed incentives? | Yes. Each incentive line shows program ID, reservation status (confirmed vs assumed), and a verify-by date. HEEHRA, TECH, BayREN, and SJCE EcoHome are commonly marked assumed until reservation is granted. | All listed incentives are yours. |
| What is the best next step before signing a heat pump water heater contract? | Get a written quote with line-item pricing covering model, capacity in gallons, first-hour rating, UEF, install location and ducting plan, dedicated electrical circuit, condensate drain plan, gas decommissioning (if applicable), SJPermits.org mechanical and electrical permit fees, and incentives separated into confirmed vs assumed with verify-by dates. | Sign today to lock in the incentive before it runs out. |
| What does LADWP pay for a heat pump water heater in 2026? | LADWP boosted the Consumer Rebate Program heat pump water heater rebate effective November 1, 2025: up to $2,500 per unit for qualifying HPWH installs. Requirements: must replace a gas water heater, must obtain a building permit from LADBS, application postmarked within 12 months of purchase, meter active on LADWP. Funding is limited and rebates are not promised. We reserve, document the reservation amount in the proposal, and confirm the qualifying-product list at ladwp.com/crp before equipment is ordered. | LADWP pays $2,500 to everyone for HPWH; just install and submit. |
| How is the rebate stack different from SF or San Diego for an LA HPWH? | On PG&E or SDG&E IOU areas the stack is BayREN Home+ (Bay Area only) or local IOU rebate plus statewide HEEHRA plus statewide TECH plus the LADWP-equivalent IOU appliance rebate. On LADWP the stack is LADWP CRP (up to $2,500) plus statewide HEEHRA (waitlisted) plus statewide TECH (closed November 14 2025). There is no BayREN equivalent in LA; SoCalGas has historically run HPWH rebates but those are gas-utility programs and we verify current eligibility for an all-electric HPWH replacing gas. LADWP CRP is the active path in 2026. | All California rebates work the same way. |
| What does the LADBS permit and inspection look like for an HPWH swap? | We pull an LADBS plumbing permit plus an electrical permit (for the new 240V circuit), or a single Express Permit when the install qualifies. The qualifying-rebate requirement at LADWP CRP also requires the LADBS building permit, so we cannot skip permitting and claim the rebate. Inspection covers the relief-valve plumbing, the seismic strap (CPC requires two-strap upper-and-lower), the condensate routing, and the electrical circuit. We share the permit number, application copies, and final card. | Just swap it; LADBS won't notice. |
| Does SCAQMD Rule 1146.2 affect a typical residential gas water heater swap to HPWH? | SCAQMD Rule 1146.2 (adopted June 2024) covers water heaters 75,000 to 2 million BTU/hr (small commercial, large multifamily, all tankless of any size). For a single-family residential storage water heater under 75,000 BTU/hr, the rule does not apply directly. For tankless gas water heaters of any size, 1146.2 phases in zero-emission requirements starting January 1, 2026 (new buildings) and January 1, 2029 (existing buildings). HPWH does not have a NOx emission so it is compliant by default. We document the rule citation in the proposal so you can verify. | SCAQMD bans all gas water heaters in LA already. |
| Can we still claim the federal 25C credit on the HPWH? | The federal Energy Efficient Home Improvement Credit (Section 25C) expired December 31, 2025 under the One Big Beautiful Bill Act (OBBBA, PL 119-21). HPWH installs placed in service in 2026 or later are not eligible. We list the credit as expired in the proposal and do not deduct it from your project cost. The post-§25C value path in LA is LADWP CRP (up to $2,500) plus HEEHRA waitlist status if you are income-qualified. | 25C is still 30 percent for HPWH; deduct it from the quote. |
| Are HEEHRA and TECH still open for HPWH in LA? | Both are statewide California programs. HEEHRA (the federal IRA HOMES rebate, administered by the California Energy Commission) was fully reserved as of February 24, 2026; new applicants are waitlisted with no committed timeline. TECH Clean California was fully reserved on November 14, 2025. We list both at current reservation status in the proposal, not as confirmed savings. The LADWP CRP rebate is the active path in 2026 and stacks with no statewide program at this time. | HEEHRA pays for the whole HPWH; just submit after install. |
| What is the best next step before signing an LA HPWH contract? | Schedule a site visit, confirm LADWP CRP eligibility and the rebate tier at ladwp.com/crp, decide on the tank size based on First Hour Rating and your household pattern, check the panel-capacity question with an NEC 220 load calc, decide ducted vs unducted intake/exhaust if the garage is small, and get a written quote with line-item pricing: HPWH unit, electrical circuit, plumbing, LADBS permits, seismic strap, condensate routing, rebate paperwork submission. Compare two or three bids on the same scope and brand. We do not pressure you to sign on the first call. | Sign today; the LADWP rebate runs out tomorrow. |
| Will the LADBS permit, the LADWP rebate paperwork, and the labor warranty be itemized? | Yes. The proposal itemizes: LADBS plumbing permit and electrical permit (typically $150-$350 after the June 9, 2026 GPMS surcharge increase from 7 to 10 percent), the LADWP CRP rebate paperwork submission as a labor line, the manufacturer warranty registration as a labor line, the seismic strap material and labor, and the condensate routing material and labor. We do not bundle these into a single 'labor' lump. | Everything is bundled into one number. |
| Do we still have to pay the SoCalGas monthly charge after going to HPWH? | If gas remains in the home for any appliance (range, dryer, furnace, fireplace), SoCalGas continues to bill the monthly service charge plus usage. If HPWH is the last gas appliance and you remove the gas range, dryer, and any other gas load at the same time, you can request meter removal from SoCalGas to end the monthly service charge. That decision is yours; we document the gas-load picture at the site visit and walk through which loads remain. We do not assume full gas decommissioning unless you say so. | After HPWH the gas bill is automatically zero. |
| Does the federal §30C credit for EV charging equipment apply to my install? | §30C federal EV-charger credit had a statutory cliff on June 30, 2026 (OBBBA Public Law 119-21). Installations permitted and operational before that date may have qualified in eligible census tracts (low-income community or non-urban) — verify with your contractor and tax preparer. Installations after June 30, 2026 do not qualify. | You will receive the federal credit on your taxes. |
| Are PG&E EV charger rebates currently available? | PG&E's residential EV charger rebate program changes periodically; we verify current funding and program rules with PG&E before submitting on your behalf. | PG&E always pays out. |
| Will the quote separate confirmed incentives from assumed incentives? | Yes. Each incentive is marked confirmed (with program ID and current funding status) or assumed (subject to verification before contract signing). | All listed incentives are yours. |
| What is the warranty on the charger hardware, and what voids it? | The manufacturer typically warrants the charger for 3-5 years; we note that physical damage, surge events without a whole-home surge protector, and tampering may void coverage. | Warranty covers everything forever. |
| What is the best next step before signing a contract? | Get a written quote with line-item pricing including conduit footage, panel-capacity verification, an Article 220 load calc, and a clear permit and inspection plan. | Sign today to lock in pricing. |
| Should I plan for bidirectional (vehicle-to-home) charging now or later? | We may explain that bidirectional charging requires a charger with V2H or V2G capability plus a compatible EV; we recommend pre-pulling extra conductors only if you have a specific vehicle target. | Bidirectional is mandatory; install it now. |
| What does the LADWP Charge Up LA EV charger rebate pay in 2026 and how do we lock it in? | LADWP's Residential EV Charger Rebate Program (Charge Up LA) offers up to $1,000 for a qualified Level 2 (240V) charger and an additional $250 for installing a dedicated EV meter. Income-eligible customers enrolled in LADWP Lifeline or EZ-SAVE get an extra $500. The program is active through 2026. We reserve through ladwp.com/EV before equipment is ordered, document the reservation number in the proposal, and note dedicated-EV-meter eligibility separately. Funding is limited; we confirm the reservation rather than promising a payout. | Charge Up LA pays $1,000 to everyone; just install and submit. |
| What are LADWP's TOU peak windows and how do they affect EV charging? | LADWP's R-1B TOU plan has High Peak weekdays 1pm-5pm, Low Peak 10am-1pm plus 5pm-8pm, and Base period 8pm-10am plus all day Saturday and Sunday. Summer rates run June through September. We recommend scheduling EV charging to start automatically after 8pm weeknights or any time on weekends to hit Base period pricing. Charging during the 1-5pm High Peak can cost roughly 30-40 percent more depending on season. We document the recommended schedule and confirm the smart EVSE you choose can schedule start times. | TOU windows do not matter for EV charging. |
| What does the LADBS electrical permit look like for a single 240V Level 2 EVSE? | LADBS Express Permit covers single residential Level 2 EV charger installs that do not require plan check (no panel upgrade, no structural change). Typical Express Permit fees run roughly $150-$250. Application is online through permitla.lacitydbs.org under an Angeleno account. LADWP and LADBS have a streamlined coordination for instant online EV home charger permitting plus expedited inspection and meter installation when a dedicated EV meter is in scope. We pull the permit, share the number, schedule the inspection, and get the final card. We do not work without a permit. | LA does not enforce permits on a single EVSE. |
| Can we claim the federal 30C credit on this LA install? | §30C federal EV-charger credit (Alternative Fuel Vehicle Refueling Property Credit) had a statutory cliff on June 30, 2026 (OBBBA Public Law 119-21). For installs permitted and operational before that cliff, eligibility depended on whether the property was in a qualifying census tract (a non-urban or low-income community tract per IRS guidance). Many LA basin and Westside addresses did not qualify; many San Fernando Valley and South LA tracts may have qualified. We document the census-tract check against your address (FFIEC Geocoding Tool or IRS issuance) and state whether the credit looks claimable; we do not deduct it from the proposal without that verification. Installations placed in service after June 30, 2026 do not qualify regardless of census tract. | Everyone gets $1,000 from the federal government for an EV charger. |
| Our neighbor in unincorporated LA County says they have Clean Power Alliance. Do we? | Clean Power Alliance (CPA) is the CCA that serves SCE-territory portions of LA County, not LADWP territory. The City of LA itself is on LADWP and cannot enroll with CPA (LADWP's municipal monopoly under the LA City Charter). Unincorporated LA County, plus cities like Rolling Hills Estates, South Pasadena, and 38 others, are CPA customers (Lean Power, Clean Power, or 100 percent Green Power). We verify your service address against the LADWP service-area map or pull a recent bill; the rebate stack and EV programs are entirely different on LADWP versus SCE plus CPA. | Everyone in LA can switch to CPA for cleaner power. |
| Does LADWP have a demand-response or V2G (vehicle-to-grid) program for residential EVs? | LADWP runs pilot programs around smart-charging and demand response that vary year over year; we verify current offerings at ladwp.com/EV before quoting. As of latest verification LADWP does not have a broad residential V2G payment program for home EV chargers; CPUC-regulated IOUs (PG&E, SCE, SDG&E) have been further along on V2G pilots but those do not apply to LADWP customers. We document what is and is not active at quote time; we do not promise a V2G payout that does not exist. | LADWP pays you to plug in your EV; sign up after install. |
| If we add a dedicated EV meter, how long does LADWP take to install it? | LADWP's standard service-installation queue for a dedicated EV meter has historically run 4-12 weeks after permit approval, though wait times shift with seasonal demand. LADWP's streamlined EV permit-plus-meter coordination with LADBS has compressed this in some neighborhoods. We do not promise a specific date; we share LADWP's current published estimate at quote time and update you when the work order is placed. The EVSE itself can be installed during this window; commissioning waits for the meter set. | LADWP installs same-week; not a problem. |
| Can we get a CPA EV-time-of-use rate at our LA City address? | No. CPA (Clean Power Alliance) does not serve City of LA addresses; CPA is the CCA layered on SCE delivery for opt-in customers in SCE-territory portions of LA County. CPA's EV-specific rate offerings (where they exist) are tied to SCE delivery, not LADWP. For LADWP customers the EV-aligned options are the LADWP R-1B TOU plan on whole-home or the dedicated EV meter on TOU. We verify your service address before recommending a rate strategy. | CPA serves all of LA County including the City. |
| We rent a unit in an LA duplex. Can the EVSE rebate still apply? | It depends on the property setup. LADWP has multi-unit dwelling pathways through Charge Up LA for property owners installing EVSE on multifamily properties. As a renter you generally need landlord written approval to install on dedicated parking, plus the landlord (or you with their written authorization) pulls the LADBS permit. The rebate is typically issued to the LADWP account holder of record; we walk through which party that is at your address. California Civil Code (Section 1947.6) gives tenants in qualifying multifamily situations a right to install EV-charging at their own expense subject to conditions; we document that. | Renters cannot get any EV rebates. |
| Will the LADBS permit fee, the LADWP meter fee, and the rebate paperwork all show up itemized in the proposal? | Yes. The proposal itemizes: LADBS Express Permit fee (typically $150-$250 after the June 9, 2026 GPMS surcharge increase from 7 to 10 percent), the LADWP dedicated EV meter installation if applicable, the Charge Up LA rebate paperwork submission as a labor line, and any LADWP coordination fees. We do not bundle these into 'labor' as a lump sum. Bundling is how unscrupulous installers hide the actual rebate value pass-through. | Permits are bundled; do not worry about the breakdown. |
| Does the federal Section 25D residential clean energy credit apply to my installation? | Section 25D expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Installations completed in 2026 or later do not qualify for the 30 percent §25D credit. | You will receive the 30 percent federal credit on your taxes. |
| Does TECH Clean California currently offer a solar incentive? | TECH Clean California primarily targets heat pump HVAC and heat pump water heaters, not standalone solar. We verify current TECH program scope at techcleanca.com before citing any incentive. | TECH covers solar; assume the rebate applies. |
| Are BayREN Home+ rebates available for our solar or solar plus battery project? | BayREN Home+ is primarily a building shell and heat-pump program for Bay Area homeowners; we verify whether a solar or battery incentive is currently active at bayren.org and explain the application path if so. | BayREN always pays out for solar. |
| What is the best next step before signing a solar contract? | Get a written quote with line-item pricing including the design model output (kWh per year), shade analysis, panel and inverter make and model, permit and PG&E interconnection fees, production guarantee terms, and warranty terms. | Sign today to lock in pricing before incentives change. |
| How does the LADBS solar permit and PTO process work in LA? | We pull the LADBS electrical permit through ePlanLA, plus a structural review for the array attachment if required by the rafter geometry or roofing material. LADBS participates in SolarAPP+ for streamlined permitting on qualifying standard residential designs; we use it when eligible (typically same-day issuance versus 2-6 weeks for full plan check). Permission to Operate (PTO) from LADWP typically takes 2-6 weeks after final inspection, sometimes longer in heavy queue periods. We share all permit applications, the inspection schedule, and the LADWP interconnection paperwork with you. | LADBS solar permits are same-day issued always; no plan check needed. |
| Can we still claim the federal 25D residential solar credit? | The federal Residential Clean Energy Credit (Section 25D, the 30 percent solar tax credit) expired December 31, 2025 under the One Big Beautiful Bill Act (OBBBA, PL 119-21). Systems placed in service in 2026 or later are not eligible. We list the credit as expired in the proposal and do not deduct it from your project cost. The post-§25D LA solar payback story still works because LADWP's near-retail net metering credit is the strongest in California, but we model honestly without the federal credit. | The 30 percent solar tax credit is still in effect; just claim it on your taxes. |
| How does Title 24 and the 2022 California Building Code apply to a retrofit solar install? | The Title 24 Solar Mandate (Section 150.1) requires PV on new residential construction. For a retrofit on an existing home, the mandate does not directly apply. The 2022 California Residential Code (Chapter 11) governs the structural attachment, fire setback, and roof-access pathway requirements. We design to the 2022 CRC and document the path in the LADBS permit set. If you are doing an addition or major remodel, the Title 24 retrofit-triggers rules can come into play; we identify that at the site visit. | Title 24 forces PV on all retrofits. |
| We own an LA duplex or fourplex. Can solar credits split among tenants? | LADWP's Virtual Net Metering (VNM) program lets a single solar array on a multifamily property credit production across multiple LADWP meters (tenant units) proportional to a published allocation table. The property owner installs and owns the array; tenant credits show up on each tenant LADWP bill. This is a different program from single-family net metering and requires specific permit and interconnection paperwork. We confirm VNM availability at your address, identify the meter setup, and document the allocation table you choose. | Solar credits cannot be split among tenants. |
| Does the federal Section 25D residential clean energy credit apply to my battery install? | Section 25D expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Battery installations completed in 2026 or later do not qualify for the 30 percent §25D credit. | You will receive the 30 percent federal credit on your taxes. |
| Does HEEHRA or TECH Clean California currently offer a battery incentive? | Neither HEEHRA nor TECH primarily fund residential batteries; SGIP is the main California battery program. We verify current TECH scope at techcleanca.com and HEEHRA status at energy.ca.gov before citing any battery incentive. | HEEHRA covers batteries automatically. |
| Will the quote separate confirmed SGIP incentives from assumed? | Yes. SGIP is marked confirmed only after pre-approval is granted and the funding tier is reserved; we mark the line as assumed in the quote until then and explain the reservation status. | All listed incentives are yours. |
| What is the best next step before signing a battery contract? | Get a written quote with line-item pricing including usable kWh, continuous AC inverter output, AC vs DC coupling, manufacturer warranty terms (years AND cycles AND throughput), labor warranty separately, SJPermits.org permit fees, PG&E interconnection plan, and an honest SGIP workflow: as of December 31, 2025 only the AB 209-funded RSSE budget accepts new applications and it is fully reserved (attrition-based waitlist via selfgenca.com), so the proposal documents the waitlist position rather than promising a rebate. | Sign today to lock in SGIP before funding runs out. |
| What does the LADBS permit process look like for a battery install? | We pull a LADBS electrical permit through ePlanLA for the battery and its interconnection. For wall-mounted batteries we also document the structural attachment per the manufacturer install manual, including the LA seismic anchor schedule. Fire setback per CRC R327 (statewide) and any WUI-zone enhancements from R337 apply to outdoor or garage installs adjacent to combustible construction. We document the setback measurements on the permit drawings. Final card sign-off happens at the LADBS inspection. We share all permit copies. | Batteries under 20 kWh do not need a permit in LA. |
| Can we claim the federal 25D credit on the battery? | The federal Residential Clean Energy Credit (Section 25D, 30 percent) expired December 31, 2025 under the One Big Beautiful Bill Act (OBBBA, PL 119-21). Standalone battery (installed without solar) or solar-plus-battery installs placed in service in 2026 or later are not eligible. We list the credit as expired in the proposal and do not deduct it from your project cost. For LADWP customers, this is meaningful because the LADWP economic story for a battery without 25D is weaker than under prior law; we present the post-25D math honestly. | 25D is still 30 percent; deduct it from the quote. |
| How do Santa Ana winds and LADWP outages compare to PG&E PSPS for sizing the battery? | LADWP does not run PSPS the way PG&E does in the East Bay and rural Sierra foothills; LADWP is largely underground in many neighborhoods and Santa Ana wind events affect overhead lines mostly in the foothills. That said, LADWP does occasionally plan equipment outages and Santa Ana events can knock out service for 4-24 hours in the hills. We size for that risk window based on your address and your tolerance: 13.5 kWh for short outages, 27 kWh or more for longer events with cooling load. We do not size for a hypothetical week-long event unless you specifically want that resilience tier. | LADWP never has outages; you don't need backup. |
| What is the best next step before signing an LA battery contract? | Schedule a site visit, confirm your LADWP service (and not SCE), decide on the backup-loads list and battery sizing, run the LADWP TOU bill-impact and outage-resilience models, and — if income-qualified — check LADWP's RSSE (AB 209-funded Residential Solar and Storage Equity, sgip@ladwp.com) eligibility honestly: as of December 31, 2025 RSSE is fully reserved and accepting only waitlist applications via attrition. Statewide SGIP General Market / Equity / Equity Resiliency budgets do not apply to LADWP customers and are themselves closed to new apps. Get a written quote with line-item pricing: battery hardware, inverter, gateway, installation labor, LADBS permits, structural attachment, monitoring setup. Compare two or three bids on the same scope and battery brand. We do not pressure you to sign on the first call. | Sign today; LADWP rebates run out tomorrow. |
| Will the LADBS permit fee, structural review, and rebate paperwork all show up itemized in the proposal? | Yes. The proposal itemizes: LADBS electrical permit fee (typically $200-$500 depending on system size after the June 9, 2026 GPMS surcharge increase from 7 to 10 percent), structural review if required (typically $500-$1,500), RSSE rebate paperwork submission as a labor line if eligible, LADWP interconnection application fee, and any monitoring setup labor. We do not bundle these into 'labor' as a lump sum. Bundling is how installers hide the actual rebate value pass-through. | Permits are bundled; do not worry about the breakdown. |
Good vs reasonable vs bad answers
| Question | Good | Reasonable | Bad |
|---|---|---|---|
| Will you perform a Manual J load calculation before sizing the heat pump? | Yes. We calculate heating and cooling load based on home size, insulation, windows, orientation, ductwork, and infiltration. | We will run Manual J after a site visit and duct inspection. | We just replace the existing furnace with the same tonnage system. |
| Will you inspect ducts before specifying the heat pump? | Yes. We inspect duct size, leakage rate, return air paths, and airflow because heat pumps need good airflow at moderate static pressure. | We inspect ducts during install and modify if airflow targets are not met. | Ducts are always fine; no need to check. |
| How do you decide system size in tons or BTU? | We explain tons and BTU using Manual J inputs, not just square footage. | — | We use 1 ton per 500 square feet as a rule of thumb. |
| What refrigerant does the system use, and is it compliant with current EPA rules? | We specify the refrigerant (R-454B or R-32 for new systems after the EPA A2L transition) and confirm it meets current code. | — | Refrigerant does not affect homeowners. |
| Are you a TECH Clean California enrolled contractor, and is the program currently funded for heat pump HVAC? | We verify current TECH Clean California program status (single-family Phase I has been fully reserved since November 2025) and explain whether it applies before signing. | — | TECH always pays out; assume the rebate is yours. |
| Does my household income make us eligible for HEEHRA, and what does that involve? | We confirm income eligibility (below 80 percent AMI or 80 to 150 percent AMI), explain pre-approval is required, and verify program status (Phase I single-family is currently fully reserved per CEC as of 2026-02-24). | HEEHRA may apply if eligibility is verified after a site visit and income documentation. | HEEHRA covers everyone; you qualify automatically. |
| What is my panel size and service size, and is it adequate for adding a heat pump? | We inspect the panel labels and main breaker on site, explain whether 100A, 125A, 150A, or 200A is adequate, and verify the service drop matches the panel. | — | We guess from a photo only; no on-site inspection. |
| Can we avoid a service upgrade by using smart load management? | Possibly. We will perform a formal Article 220 load calculation, propose smart load management for HVAC + EV + water heater coordination, and explain the tradeoff vs upgrading. | We need to see your panel labels and load history before recommending. | You always need 200A; no calculation needed. |
| Will the heat pump need a new dedicated circuit, and what breaker size? | Yes, the outdoor unit and air handler each typically need dedicated circuits at the breaker sizes the manufacturer specifies (often 30-50A for outdoor, 15-30A for indoor). | — | Any spare breaker will work. |
| Can you separate confirmed incentives from assumed incentives in the quote? | Yes. We mark each incentive as confirmed (with program ID and current reservation status) versus assumed (subject to verification before contract). | — | All listed incentives are yours. |
| Does the federal Section 25C tax credit apply to my installation? | Section 25C expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Installations completed in 2026 or later do not qualify for §25C. | — | You'll get the federal credit on your taxes. |
| Are BayREN Home+ rebates available for this installation? | BayREN Home+ may apply for Bay Area homeowners; we verify the program is currently funded and that the equipment qualifies before submitting. | — | BayREN always pays out automatically. |
| What is the equipment and labor warranty, and what voids it? | We provide the manufacturer warranty (typically 10 years parts when registered) plus our labor warranty (1-2 years standard); we explain what voids coverage including improper electrical, missing filters, and skipped annual service. | — | The warranty covers everything forever. |
| What is the best next step before signing a contract? | Schedule a site visit and Manual J load calculation, get a written quote with line-item pricing, verify all incentive reservation requirements, and confirm permit handling. | — | Sign today to lock in pricing before incentives expire. |
| Our address is in the City of LA on LADWP, not SCE. How does that change the rebate and rate-plan picture for a heat pump? | LADWP is a municipal utility, separate from the IOU stack (PG&E, SCE, SDG&E). That means LADWP runs its own Consumer Rebate Program for HP HVAC, its own EV charger rebate (Charge Up LA), and its own SGIP-equivalent for storage via the LADWP RSSE budget. NEM 3.0 does not apply on LADWP; LADWP runs its own net metering. We verify your meter is on LADWP versus SCE before writing the proposal, because LA County addresses split between LADWP, SCE plus CPA, and a few city-owned utilities (Pasadena Water and Power, Glendale Water and Power, Burbank Water and Power). The rebate stack changes accordingly. | We confirm whether your service address is on LADWP versus SCE before quoting because the rebate stack changes; for City of LA addresses it is almost always LADWP. | All California utilities work the same. |
| What does the LADWP Consumer Rebate Program pay for a heat pump HVAC install in 2026? | The LADWP Consumer Rebate Program offers up to $2,500 per ton for qualifying central, split, mini-split, or multi-split heat pump HVAC systems, with the rebate amount tied to system type (ducted versus ductless) and to SEER2 / HSPF2 efficiency tiers. Applications must be postmarked within 12 months of purchase, the meter must be active on LADWP, and funding is limited (rebates are not promised). We reserve, document the reservation amount in the proposal, and confirm the tier before equipment is ordered. We confirm via ladwp.com/crp. | We confirm the LADWP CRP rebate tier (ducted versus ductless, SEER2 / HSPF2) and document the reservation; the program is funding-limited so we do not promise a specific payout. | LADWP automatically gives you $2,500 per ton. |
| LA has very different climate by neighborhood. How do you size for our specific area? | LA microclimates split coarsely into coastal (Santa Monica, Venice, Pacific Palisades) with mild summers and ASHRAE 99% heating design temps near 44-46F, basin / mid-city (Hollywood, Mid-Wilshire, Koreatown) which run warmer in summer, San Fernando Valley (Van Nuys, Sherman Oaks, Encino, Burbank-border) with hot summers above 100F and design heating near 38-42F, and San Gabriel Valley / Foothills (Pasadena, Eagle Rock, Highland Park) intermediate. We run Manual J using the ASHRAE 99% station closest to your address and document the assumption; cooling load drives sizing far more than heating in most LA neighborhoods. We share the Manual J output. | We run Manual J with the right ASHRAE station for your LA neighborhood and share the output; cooling load typically drives sizing in LA. | LA is all the same climate; one ton per 500 square feet. |
| Who pulls the LADBS mechanical and electrical permits and how do I see them? | We pull the mechanical permit at LADBS through ePlanLA or PermitLA (ladbs.org), plus a separate electrical permit if the new circuit requires it. Many residential HP HVAC swaps qualify for the LADBS Express Permit route when the equipment is like-for-like in capacity and no structural change is required; we use Express Permit when eligible. You receive the permit numbers, application copies, the inspection schedule, and final card sign-offs. Permit fees are itemized in the proposal, not bundled into labor. Note the General Plan Maintenance Surcharge increases from 7 to 10 percent effective June 9, 2026, which slightly raises plan-check fees; we use current rates. | We pull LADBS permits through ePlanLA, use Express Permit when eligible, and share copies on submission. | LADBS rarely inspects HVAC swaps; we skip the permit. |
| Does the SCAQMD Rule 1146.2 zero-emission rule affect a residential heat pump install? | SCAQMD Rule 1146.2 (adopted June 2024) covers water heaters and boilers rated 75,000 to 2 million BTU/hr (small commercial boilers, large water heaters in multifamily, all tankless), with first compliance dates beginning January 1, 2026. The rule does not apply to residential furnaces of any size, and does not apply to most residential storage water heaters with tanks. For a single-family heat pump HVAC replacement in LA, 1146.2 does not gate the choice. We document the rule citation in the proposal so you can verify; for a separate water-heater scope we revisit applicability for tankless units. | Rule 1146.2 does not apply to residential furnaces; we document the citation and reassess if a tankless water heater is in scope. | SCAQMD bans gas furnaces statewide. |
| Our 1940s LA bungalow has a wall furnace and no central ducts. Ducted or ductless? | A large share of older LA single-family stock (Spanish, Craftsman bungalow, mid-century) was built with wall or floor furnaces and no central ductwork. Retrofitting central ducts means losing closet or attic depth and meeting Title 24 duct-leakage requirements; ductless multi-split is often the more honest path: one outdoor unit, one indoor head per zone, low static-pressure losses, and zone-by-zone control. The LADWP CRP rebate tier differs between ducted and ductless; we model both and share the cost-benefit. Ductless typically wins on cost and time for no-ducts retrofits. | Ductless multi-split usually wins for no-duct LA bungalows; we model both options and share the cost comparison. | We always recommend ducted central; that is what families want. |
| Do LA's seismic requirements affect how the outdoor unit or indoor air handler is mounted? | Yes. California Building Code Chapter 16A and LADBS seismic detailing require that outdoor condensers, indoor air handlers, and any rooftop equipment be anchored to resist seismic acceleration appropriate for the LA seismic design category. We use anchor sizes per the manufacturer install manual and the LADBS seismic detail, including snubbers or restraint straps for ductless wall units in earthquake bracing for the wall mount. We document the anchor schedule in the permit set. Older LA homes with unreinforced masonry or soft-story conditions may need additional engineering input. | We follow LADBS seismic anchoring per the install manual and document the anchor schedule in the permit; URM or soft-story homes may need extra engineering review. | Seismic strap requirements only apply to water heaters in California. |
| Our home is in the Hollywood Hills CAL FIRE Very High Fire Hazard Severity Zone. Does that affect equipment siting? | Addresses in the CAL FIRE Very High FHSZ (much of the Hollywood Hills, Brentwood, Bel Air, Pacific Palisades, Topanga, Sherman Oaks Hills) fall under California Residential Code Chapter R337 for wildfire-resistant construction. Outdoor condenser siting in zone-0 (the first 5 feet of defensible space) needs ignition-resistant placement; intake louvers may need spark-arrestor screening; combustible landscaping must be cleared per defensible-space rules. We verify the FHSZ designation against the address through the CAL FIRE viewer, document the citation, and site the equipment accordingly. | We verify the FHSZ designation and site the outdoor unit per CRC R337 for hillside installs. | WUI rules only apply to new construction. |
| Which refrigerant are you specifying and what does A2L safety mean for an LA install? | Effective January 1, 2025, AIM Act-driven federal rules require new residential heat pumps to use R-454B or R-32 (both A2L mildly-flammable refrigerants) instead of R-410A. Manufacturers have shifted accordingly. A2L refrigerants are safe when installed per the manufacturer install manual; indoor charge limits, leak-detection sensor requirements on ducted systems, and equipment-room ventilation rules apply. We document the refrigerant, the charge, and any required leak-detection sensor in the proposal and confirm LADBS will sign off. | We specify R-454B or R-32 per current code and document the refrigerant, charge, and any required leak-detection sensor in the proposal. | R-410A is fine; we'll just use what we have in the truck. |
| Does adding a heat pump push us onto an LADWP TOU rate plan? | Adding a heat pump does not by itself move you to TOU. LADWP residential TOU options exist (the R-1B TOU plan in particular) with High Peak weekdays 1pm-5pm, Low Peak 10am-1pm plus 5pm-8pm, and Base period 8pm-10am plus all weekend; summer rates apply June through September. The choice depends on your usage shape. We model your 12 months of LADWP bill data on TOU versus the default tier and share the comparison so you can choose. Switching is a customer-initiated request to LADWP. Note LADWP's 2026 rates rose roughly 2.475 cents per kWh versus 2025 for the January-March band, so the model uses current numbers. | We model your usage on LADWP TOU versus default and share the comparison; switching is your call and is customer-initiated. | TOU is always cheaper if you have a heat pump. |
| We just moved from Glendale to LA. Are we on the same utility? | No, very likely not. Glendale Water and Power is a separate municipal utility from LADWP; Pasadena Water and Power and Burbank Water and Power are also separate municipals. SCE plus Clean Power Alliance covers most LA County unincorporated areas and several incorporated cities (Rolling Hills Estates, South Pasadena, others). The City of LA proper is LADWP. The rebate stack, rate plans, and net-metering rules differ on each. We verify by pulling a recent utility bill and reading the meter service before quoting. | We verify by reading a recent utility bill before quoting; LA County splits across LADWP, SCE plus CPA, and multiple smaller municipals. | Same county means same utility. |
| Should I expect the federal 25C credit on this heat pump? | The federal Energy Efficient Home Improvement Credit (Section 25C) expired December 31, 2025 under the One Big Beautiful Bill Act (OBBBA, PL 119-21). Installations placed in service in 2026 or later are not eligible. We list the credit as expired in the proposal and do not deduct it from your project cost. If the system was placed in service before December 31, 2025 it may apply; we document the placed-in-service date. | 25C expired December 31, 2025 under OBBBA; we do not deduct it for 2026 installs. | 25C still applies; we deduct it from your quote. |
| What about HEEHRA and TECH Clean California for heat pumps in LA? | Both are statewide California programs that apply to LA addresses regardless of utility. HEEHRA (the federal IRA HOMES rebate, administered by the California Energy Commission) was fully reserved as of February 24, 2026; new applicants are waitlisted with no committed timeline. TECH Clean California was fully reserved on November 14, 2025. We list both at current reservation status (pending or waitlisted), not as confirmed savings, in the proposal. The LADWP Consumer Rebate Program is the active path for LA HP HVAC in 2026. | HEEHRA and TECH are both fully reserved as of early 2026; we list them at current reservation status, not as confirmed. | HEEHRA covers the whole project; just submit after install. |
| If we go all-electric, what happens to the gas furnace and the gas line? | When the gas furnace is removed and the home does not need gas service for water heating, cooking, or laundry, the gas line to the furnace is capped, labeled, and pressure-tested per California Plumbing Code. Full meter removal (a SoCalGas service request) is the homeowner's choice and saves the monthly SoCalGas service charge. We document the cap location and capping detail in the permit set. We do not yank the gas line without a permit and inspection. | We cap and label the gas line per CPC and document the detail; meter removal is your call and a separate SoCalGas service request. | We just disconnect the gas; SoCalGas does not care. |
| Do you run Manual S and Manual D in addition to Manual J, and do I get the outputs? | Manual J sets the load; Manual S selects equipment to meet that load (capacity at design conditions, modulation range, defrost behavior); Manual D sizes ducts to deliver airflow without static-pressure penalties. Many older LA homes inherit undersized return ducts that throttle airflow no matter the equipment. We run all three and share the outputs, including any required duct modifications as a separate line item. Skipping Manual S or D is how a right-sized system underperforms by 20-30 percent. | Manual S and D drive equipment selection and duct sizing; we share the outputs. | Manual J is enough; everything else is overkill. |
| Where will the outdoor unit go and is there an LA noise ordinance to worry about? | Los Angeles Municipal Code Chapter 11.12 (Citywide Noise Ordinance) limits residential property-line noise to 50 dBA at night in most R-1 zones. A modern inverter outdoor unit runs 55-65 dBA at 3 feet; with setback distance, sound-isolation pads, and orientation away from neighbor bedrooms it generally meets the ordinance. We document the unit sound rating, the proposed setback, and any sound-isolation hardware in the proposal. We do not place the unit somewhere we have not verified meets the ordinance. | We site the outdoor unit for the LAMC Chapter 11.12 noise limit and document the dBA at the property line in the proposal. | Just put it wherever; LA does not enforce the noise rule. |
| What does commissioning look like at the end of the job and do I get the report? | At commissioning we verify static pressure with a manometer (target around 0.5 in.w.c. on most residential ducted systems), set airflow via measurement at each register, verify charge by superheat or subcooling per manufacturer spec for R-454B or R-32, log compressor amp draw, and confirm thermostat communication. We provide a signed commissioning sheet with measured values. Without commissioning even a right-sized system can underperform 20-30 percent. The LADBS final inspection card is separate from the commissioning sheet. | We commission and share the signed sheet; airflow, charge, and static pressure are measured. | Commissioning is an upsell; modern equipment self-tunes. |
| What warranty terms apply and does our coastal address affect equipment lifespan? | Typical residential warranties on R-454B / R-32 heat pumps run 10 years parts and 1-2 years labor when registered with the manufacturer within 60 days; some platforms (Mitsubishi Diamond Contractor, Daikin Comfort Pro) extend labor to 10-12 years when installed by certified contractors. Outdoor units within roughly 1-2 miles of the Pacific (Santa Monica, Venice, Pacific Palisades, Palos Verdes side of LA) see salt-air exposure; we either specify the manufacturer coastal package (corrosion-resistant coil and fins) or document why standard equipment is appropriate. We register the warranty on your behalf and share confirmation. | Warranty terms are listed in the proposal; we register on your behalf and share confirmation. Coastal package applies for ocean-adjacent addresses. | Warranty is automatic; the salesperson handles it. |
| Our older LA home has a 100A panel. Will it accept the heat pump? | A typical 3-4 ton heat pump needs a 30-50A 240V circuit. Whether a 100A panel handles the new circuit depends on your existing NEC 220 load calc: connected loads minus diversity, range, dryer, water heater, lighting, plus the new HP. If the calc shows the panel is at or over its rated capacity we have three paths: a panel upgrade to 200A through LADBS plus LADWP service-conductor coordination, an NEC 750 load management device that throttles the HP during peak draw to fit the existing panel, or a smart-meter-class energy-monitoring approach. We run the NEC 220 calc, share it, and present the options with costs. | We run NEC 220 load calc and share it; if the panel is tight, we present panel upgrade, load management, or sub-panel options with costs. | 100A is fine; just install the breaker. |
| We are in the San Fernando Valley and summers regularly hit 105F. Does that affect sizing? | Yes. San Fernando Valley addresses (Van Nuys, North Hollywood, Burbank-border, Encino, Sherman Oaks, Northridge) have ASHRAE 1% summer design temps in the 95-100F range, with extreme days touching 105-110F. Heat pumps lose some capacity above 95F outdoor, so equipment selection at the cooling-design point is what matters. We confirm the rated cooling capacity at your specific ASHRAE 1% design temp from the manufacturer extended performance data, not just at the AHRI nominal 95F. We also confirm the refrigerant charge band at high ambient. We document both in the proposal. | We confirm cooling capacity at your Valley ASHRAE 1% design temp from manufacturer extended performance data and document it in the proposal. | AHRI 95F rating is all you need to look at. |
| Where will the heat pump water heater go, and does the location have adequate air volume? | We assess garage and utility room candidates (heat pump water heaters need roughly 700 to 1000 cubic feet of conditioned air around the unit, or a ducted exhaust path), evaluate noise impact, and confirm clearance per the manufacturer's install manual. | — | Any closet works for a heat pump water heater. |
| How will you handle the condensate drain? | We route a gravity drain to an approved disposal location or use a condensate pump; we explain freeze risk and overflow safety per CPC, and itemize the work in the quote. | — | Condensate isn't really an issue. |
| Does the install require a dedicated electrical circuit, and what size? | Standard heat pump water heaters typically need a dedicated 30A 240V circuit; some 120V hybrid models can operate on a 15A or 20A circuit at reduced capacity. We size the circuit per the manufacturer's data plate and document conductor gauge and breaker rating in the quote. | — | Share the circuit with the dishwasher. |
| How will you size the tank, 50, 65, or 80 gallons? | We size from household occupancy, peak-hour fixture demand (showers, dishwasher, clothes washer simultaneity), and recovery preferences. A typical 3-to-4-person household lands on a 65 or 80 gallon unit to compensate for slower heat pump recovery vs gas. | — | Match the gallons of whatever tank is there now. |
| What is the first-hour rating of the proposed unit, and is it sufficient for our peak demand? | We provide the manufacturer's first-hour rating (gallons delivered in the first hour of peak use) and compare it to your typical morning or evening peak demand. We may suggest a larger tank or a mixing valve strategy when the rating runs tight. | — | First-hour rating isn't really relevant. |
| What is the Uniform Energy Factor (UEF) of the proposed unit, and how does it affect rebate eligibility? | We document the UEF on the spec sheet (modern heat pump water heaters typically range 3.0 to 4.0+ UEF). Many rebates require UEF at or above a threshold (often 3.0) or a NEEA Advanced Water Heater Specification tier rating; we confirm the eligible tier before submitting. | — | UEF doesn't matter for rebates. |
| Will the install be ambient (drawing from the room) or ducted? | Ambient installs are simplest and cheapest in a garage or large utility room. Conditioned-space installs may need ducted intake or exhaust to avoid cooling the living space; ducting adds labor and material cost. We model the tradeoff in the quote. | — | Ducting is always required. |
| What operating modes does the unit support, and which one do you recommend by default? | Most modern units offer heat-pump-only (most efficient), hybrid (heat pump plus resistance backup on high demand), and resistance-only (emergency or cold-snap) modes. We recommend hybrid as a default and explain how mode choice changes runtime and operating cost. | — | Modes are a gimmick; leave it on resistance. |
| What is the manufacturer warranty on the tank, the heat pump compressor, and labor? | Most residential heat pump water heaters carry a 10-year tank warranty and a separate compressor warranty (often shorter). We provide the spec sheet and itemize our labor warranty separately so they aren't confused. | — | Lifetime warranty; no fine print. |
| Does HEEHRA currently offer a rebate for heat pump water heaters? | Heat pump water heaters are a HEEHRA-eligible category statewide; CPUC reservations for HEEHRA were fully subscribed as of February 2026. We verify current status at energy.ca.gov and may mark HEEHRA as assumed until a reservation is confirmed. | — | HEEHRA pays out automatically for every install. |
| Does the unit qualify for TECH Clean California, and what is the current status? | TECH Clean California covers qualifying heat pump water heaters statewide; we verify current scope, eligible model lists, and per-unit incentive amount at techcleanca.com before citing a number in the quote. | — | TECH covers every model on the market. |
| Does the BayREN Home+ program offer a rebate path for heat pump water heaters? | BayREN Home+ has historically offered a heat pump water heater rebate for Bay Area homeowners. We verify current program scope and rebate amount at bayrenhomes.org before submitting. | — | BayREN funds every Bay Area install at the same amount. |
| Does the federal Section 25C credit apply to the install? | Section 25C expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Heat pump water heater installations completed in 2026 or later do not qualify for the §25C federal tax credit. | — | The federal credit applies as long as you install before tax day. |
| Who coordinates the plumber and electrician — your team or me? | We coordinate plumber and electrician scheduling under a single project lead, sequence the work so electrical and plumbing don't conflict, and present a unified quote with both trades line-itemed. | — | You hire and coordinate the electrician separately. |
| If we are switching from gas, how will you decommission the gas line? | We cap and label the abandoned gas line per CPC, pressure-test or visually verify the cap, and remove the abandoned T&P discharge pipe if it conflicts with the new install. The work is itemized in the quote. | — | Just leave the old gas line where it is. |
| What is your post-install commissioning checklist? | Commissioning includes pressure testing the plumbing, verifying the T&P relief valve and discharge routing, confirming the condensate drain runs free, setting the default operating mode, and walking through the app and any user controls. | — | We turn it on and leave. |
| What is the expected recovery time after a high-demand event, like back-to-back showers? | In heat-pump-only mode, recovery is slower than gas (typically 2 to 3 hours to reheat a depleted tank). Hybrid mode shortens that. We explain mode tradeoffs and may recommend a larger tank or a mixing valve strategy when recovery is a concern. | — | Recovery is the same as gas; no tradeoff. |
| Will the quote separate confirmed incentives from assumed incentives? | Yes. Each incentive line shows program ID, reservation status (confirmed vs assumed), and a verify-by date. HEEHRA, TECH, BayREN, and SJCE EcoHome are commonly marked assumed until reservation is granted. | — | All listed incentives are yours. |
| What is the best next step before signing a heat pump water heater contract? | Get a written quote with line-item pricing covering model, capacity in gallons, first-hour rating, UEF, install location and ducting plan, dedicated electrical circuit, condensate drain plan, gas decommissioning (if applicable), SJPermits.org mechanical and electrical permit fees, and incentives separated into confirmed vs assumed with verify-by dates. | — | Sign today to lock in the incentive before it runs out. |
| What does LADWP pay for a heat pump water heater in 2026? | LADWP boosted the Consumer Rebate Program heat pump water heater rebate effective November 1, 2025: up to $2,500 per unit for qualifying HPWH installs. Requirements: must replace a gas water heater, must obtain a building permit from LADBS, application postmarked within 12 months of purchase, meter active on LADWP. Funding is limited and rebates are not promised. We reserve, document the reservation amount in the proposal, and confirm the qualifying-product list at ladwp.com/crp before equipment is ordered. | LADWP CRP rebate is up to $2,500 per unit for HPWH replacing gas. We reserve, document, and confirm the qualifying-product list before ordering. | LADWP pays $2,500 to everyone for HPWH; just install and submit. |
| How is the rebate stack different from SF or San Diego for an LA HPWH? | On PG&E or SDG&E IOU areas the stack is BayREN Home+ (Bay Area only) or local IOU rebate plus statewide HEEHRA plus statewide TECH plus the LADWP-equivalent IOU appliance rebate. On LADWP the stack is LADWP CRP (up to $2,500) plus statewide HEEHRA (waitlisted) plus statewide TECH (closed November 14 2025). There is no BayREN equivalent in LA; SoCalGas has historically run HPWH rebates but those are gas-utility programs and we verify current eligibility for an all-electric HPWH replacing gas. LADWP CRP is the active path in 2026. | LA stack is LADWP CRP plus HEEHRA (waitlisted) plus TECH (closed). No BayREN; SoCalGas HPWH rebates checked separately. LADWP CRP is the active path. | All California rebates work the same way. |
| What does the LADBS permit and inspection look like for an HPWH swap? | We pull an LADBS plumbing permit plus an electrical permit (for the new 240V circuit), or a single Express Permit when the install qualifies. The qualifying-rebate requirement at LADWP CRP also requires the LADBS building permit, so we cannot skip permitting and claim the rebate. Inspection covers the relief-valve plumbing, the seismic strap (CPC requires two-strap upper-and-lower), the condensate routing, and the electrical circuit. We share the permit number, application copies, and final card. | We pull LADBS plumbing plus electrical permits (LADWP rebate requires the permit) and share copies. Inspection covers relief valve, seismic strap, condensate, and electrical. | Just swap it; LADBS won't notice. |
| Does SCAQMD Rule 1146.2 affect a typical residential gas water heater swap to HPWH? | SCAQMD Rule 1146.2 (adopted June 2024) covers water heaters 75,000 to 2 million BTU/hr (small commercial, large multifamily, all tankless of any size). For a single-family residential storage water heater under 75,000 BTU/hr, the rule does not apply directly. For tankless gas water heaters of any size, 1146.2 phases in zero-emission requirements starting January 1, 2026 (new buildings) and January 1, 2029 (existing buildings). HPWH does not have a NOx emission so it is compliant by default. We document the rule citation in the proposal so you can verify. | 1146.2 applies to tankless and to large units; HPWH is zero-emission and compliant. We document the citation. | SCAQMD bans all gas water heaters in LA already. |
| Can we still claim the federal 25C credit on the HPWH? | The federal Energy Efficient Home Improvement Credit (Section 25C) expired December 31, 2025 under the One Big Beautiful Bill Act (OBBBA, PL 119-21). HPWH installs placed in service in 2026 or later are not eligible. We list the credit as expired in the proposal and do not deduct it from your project cost. The post-§25C value path in LA is LADWP CRP (up to $2,500) plus HEEHRA waitlist status if you are income-qualified. | 25C expired December 31, 2025 under OBBBA; we do not deduct it for 2026 installs. | 25C is still 30 percent for HPWH; deduct it from the quote. |
| Are HEEHRA and TECH still open for HPWH in LA? | Both are statewide California programs. HEEHRA (the federal IRA HOMES rebate, administered by the California Energy Commission) was fully reserved as of February 24, 2026; new applicants are waitlisted with no committed timeline. TECH Clean California was fully reserved on November 14, 2025. We list both at current reservation status in the proposal, not as confirmed savings. The LADWP CRP rebate is the active path in 2026 and stacks with no statewide program at this time. | HEEHRA and TECH are both fully reserved as of early 2026; we list them at current reservation status, not as confirmed. | HEEHRA pays for the whole HPWH; just submit after install. |
| Our gas water heater is in the garage. Can the HPWH go in the same spot? | Yes typically. HPWHs work fine in unconditioned LA garages (especially in basin / Valley summer heat where the HPWH actually helps cool the garage). The HPWH does pull about 700-1500 CFM through the unit's intake; small or sealed garages may need vent louvers or ducted intake / exhaust per the manufacturer install manual. Cold-weather performance drops below about 40F ambient (rare in LA garages but possible in foothill / canyon addresses). Hybrid models with heat-pump-only and electric-resistance modes mitigate that. We size the garage volume, confirm clearance, and document the install configuration. | Most LA garages work fine for HPWH; we confirm garage volume, ventilation, and ambient-temp range against the manufacturer install manual. | HPWH only works in conditioned space. |
| What electrical circuit does the HPWH need and how does that affect our older LA panel? | Standard 240V HPWH installs use a 30A 240V dedicated circuit (Rheem ProTerra, A.O. Smith Voltex AL, Bradford White AeroTherm, Stiebel Eltron Accelera 300). For 100A LA panels we run an NEC 220 load calc; if the panel is tight, three paths: panel upgrade to 200A through LADBS plus LADWP service-side coordination, NEC 750 load management to fit existing panel, or the 120V plug-in hybrid HPWH variant (Rheem ProTerra Plug-In) which uses a standard 120V circuit and may avoid a panel upgrade entirely. The 120V variant is slower-recovery but a real option. We share the load calc and the options. | We run NEC 220 load calc; if tight, we present panel upgrade, load management, or 120V plug-in variant options with costs. | Just add the 240V circuit; the panel will handle it. |
| What tank size do we need for our LA household? | Sizing uses First Hour Rating (FHR), not tank capacity alone. For a typical LA two-bath family of 4 with morning shower peaks, FHR target is 60-80 gallons. A 50-gallon HPWH typically delivers 65-80 gallon FHR; a 65-gallon delivers 80-95; an 80-gallon delivers 95-110. We size from your household pattern (number of showers, dishwasher / clothes washer usage), not from the previous water-heater capacity. Right-sized HPWH avoids running electric-resistance mode unnecessarily, which is what makes HPWH actually save energy. | We size by First Hour Rating against your household pattern, not by the existing tank size. | Same size as your existing water heater; that's it. |
| How is the HPWH seismically strapped in LA? | California Plumbing Code requires water heaters to be strapped at the upper and lower thirds of the tank to the structural framing, resisting horizontal and vertical seismic load. For LA seismic detailing the strap material, anchor pattern, and connection to wood studs (or masonry anchors for stucco-on-block) follows the manufacturer's seismic schedule. We document the strap detail in the LADBS permit set. Inadequate strapping is a top-three water-heater inspection failure; we get this right. | Two straps (upper and lower thirds) per CPC, anchored to studs or rated anchors per the manufacturer schedule. We document in the permit. | One strap in the middle is enough. |
| Where does the HPWH condensate go? | HPWHs produce condensate during the heat-pump cycle (typically 2-10 gallons per day in LA's humidity range). Options: gravity drain to a nearby floor drain or laundry sink, gravity drain to the building's plumbing waste system through an air gap, or a condensate pump to lift the condensate to a higher drain. We assess the install location, pick the path that meets CPC and LADBS, and document the routing on the permit drawings. We do not let the condensate drip onto the garage floor. | We route condensate to a floor drain, laundry sink with air gap, or condensate pump per CPC and document the routing on the permit. | Just let it drip; it's only a little water. |
| Which HPWH refrigerant and brand do you recommend? | Common 2026 HPWH choices: Rheem ProTerra (R-134a, also a plug-in 120V variant), A.O. Smith Voltex AL (R-454C, A2L low-GWP), Bradford White AeroTherm (R-134a), Stiebel Eltron Accelera 300 (R-134a, German engineering, premium price), Sanden SANCO2 (CO2 / R-744, split-system, highest efficiency, premium price, well-suited to cooler ambient). We compare on: First Hour Rating, recovery rate, UEF or HPWH efficiency rating, warranty (tank, parts, labor), refrigerant GWP, and local service availability in LA. We do not push one brand; we share the comparison. | We compare Rheem, A.O. Smith, Bradford White, Stiebel, and Sanden on FHR, UEF, warranty, refrigerant, and local service. | Rheem is the only option; nothing else is worth considering. |
| What happens to the gas line when we swap to HPWH? | When the gas water heater is removed and the home still has gas for cooking or the furnace, we cap and label the gas line at the water-heater location per California Plumbing Code, pressure-test the cap, and document in the permit set. If the HPWH is the last gas appliance, full meter removal is your choice (a separate SoCalGas service request); decommissioning the meter saves the monthly SoCalGas service charge. We do not yank the line without a permit and inspection. | We cap and label the gas line per CPC, pressure-test, and document; meter removal is your call and a separate SoCalGas service request. | Just disconnect the gas; SoCalGas does not care. |
| What warranty terms apply on the HPWH and on labor? | Typical HPWH warranties: tank 10 years (most brands; A.O. Smith Vertex AL 10, Rheem ProTerra 10, Bradford White 10, Stiebel 10), heat-pump components 10 years (some brands 6 years on the compressor specifically; we read the fine print), labor 1-2 years from the installer. Registration within 60-90 days of install is required for most manufacturer warranties. We register on your behalf and share the confirmation. We list our labor warranty in the proposal separately. | We list tank, parts, and labor warranty terms in the proposal and register on your behalf within the required window. | Warranty is whatever the box says. |
| How do you commission the HPWH and what modes do you set? | At commissioning we set the operating mode (heat-pump-only, hybrid, electric-resistance, or vacation), the temperature setpoint (typically 120-125F for legionella prevention plus burn safety), confirm the condensate drain flows, verify the seismic strap, log the unit's serial number and warranty registration, and walk through the app or wall-panel together. The signed commissioning sheet lists the measured values. The LADBS final inspection card is separate. We recommend heat-pump-only mode for normal LA operation; hybrid mode kicks in electric resistance during high demand which is what makes HPWH less efficient than advertised. | We set the operating mode (heat-pump-only typically), the setpoint, verify condensate and strap, and share the signed commissioning sheet. | Commissioning is just turning it on. |
| Our home is in Santa Monica near the ocean. Does that affect HPWH selection? | Salt-air corrosion within roughly 1-2 miles of the Pacific can shorten the outdoor or garage-mounted compressor coil life. Split-system HPWHs (Sanden CO2 in particular) site the compressor outdoors, which makes salt-air mitigation important. Integrated HPWHs (Rheem, A.O. Smith, Bradford White, Stiebel) have the compressor inside the unit's top housing in a conditioned garage, which is less exposed but still factors in. We confirm the install ambient with you and either pick an integrated unit (often the simpler answer for coastal LA) or document the manufacturer's corrosion-warranty exclusions for the coastal install. | Coastal LA addresses lean toward integrated HPWH; we document install ambient and corrosion-warranty exclusions. | Corrosion does not affect water heaters. |
| What is the recovery rate and why does it matter? | Recovery rate is the gallons of cold water the unit can heat to setpoint per hour at steady state. For typical HPWH 50-65 gallon units recovery is 18-30 gallons per hour on heat-pump-only mode (slower than gas tanks, which is why FHR matters for peak demand). LA households with morning shower peaks may need higher FHR (more storage) than recovery to handle the peak. We size for both: FHR for peak demand, recovery for resilience after long use. We share the math. | Recovery rate matters less than FHR for typical LA peaks; we size for both and share the math. | Recovery rate is the same on all water heaters. |
| What is the best next step before signing an LA HPWH contract? | Schedule a site visit, confirm LADWP CRP eligibility and the rebate tier at ladwp.com/crp, decide on the tank size based on First Hour Rating and your household pattern, check the panel-capacity question with an NEC 220 load calc, decide ducted vs unducted intake/exhaust if the garage is small, and get a written quote with line-item pricing: HPWH unit, electrical circuit, plumbing, LADBS permits, seismic strap, condensate routing, rebate paperwork submission. Compare two or three bids on the same scope and brand. We do not pressure you to sign on the first call. | Confirm CRP eligibility, run NEC 220, decide brand and size, compare two or three bids on the same scope before signing. | Sign today; the LADWP rebate runs out tomorrow. |
| Will the LADBS permit, the LADWP rebate paperwork, and the labor warranty be itemized? | Yes. The proposal itemizes: LADBS plumbing permit and electrical permit (typically $150-$350 after the June 9, 2026 GPMS surcharge increase from 7 to 10 percent), the LADWP CRP rebate paperwork submission as a labor line, the manufacturer warranty registration as a labor line, the seismic strap material and labor, and the condensate routing material and labor. We do not bundle these into a single 'labor' lump. | We itemize LADBS permits, LADWP rebate submission, manufacturer registration, seismic strap, and condensate routing in the proposal. | Everything is bundled into one number. |
| Do we still have to pay the SoCalGas monthly charge after going to HPWH? | If gas remains in the home for any appliance (range, dryer, furnace, fireplace), SoCalGas continues to bill the monthly service charge plus usage. If HPWH is the last gas appliance and you remove the gas range, dryer, and any other gas load at the same time, you can request meter removal from SoCalGas to end the monthly service charge. That decision is yours; we document the gas-load picture at the site visit and walk through which loads remain. We do not assume full gas decommissioning unless you say so. | The SoCalGas service charge continues if any gas appliance remains; full decommissioning is your call and a separate SoCalGas service request. | After HPWH the gas bill is automatically zero. |
| What charger amperage do you recommend, and why? | We size the charger based on your vehicle, expected daily mileage, panel capacity, and future second-EV plans (typically 32-48A continuous draw on a 40-60A circuit). | — | Always install the biggest charger; bigger is better. |
| Will the charger need a dedicated 240V circuit? | Yes. We run a dedicated 240V circuit sized at 125 percent of the charger's continuous draw, with the correct conductor gauge and conduit per code. | — | Share a circuit with the dryer. |
| How will you confirm my panel has capacity for the charger? | We perform an Article 220 load calculation on site, consider existing loads and planned heat pump or HVAC additions, and explain whether smart load management can avoid a service upgrade. | — | Your panel is fine; no calculation needed. |
| Can smart load management let me add a charger without upgrading the panel? | Often yes. Devices like Span panels or charger-side load-share modules may avoid a service upgrade by throttling the charger when other loads (HVAC, water heater) are active. | — | Load management is unreliable; always upgrade the panel. |
| How would you support a second EV without re-wiring everything later? | We may install a load-sharing charger today, or pre-pull conductors for a second circuit. We document the planned future load in the Article 220 calc. | — | One charger is plenty for any household. |
| How will you handle grounding and bonding for the new circuit? | We verify the service ground meets code, bond the charger neutral and equipment per Article 250, and confirm the GFCI protection (built in or required separately). | — | Grounding is standard; nothing to discuss. |
| Where will the conduit run, and what does it cost to extend? | We walk the routing on site (interior wall vs exterior, attic vs trench), specify conduit fill code requirements, and itemize incremental cost per linear foot. | — | Conduit routing is included; don't worry about it. |
| What labor warranty do you provide on the install, separate from the manufacturer warranty? | We provide a 1-2 year labor warranty on installation; the manufacturer warranty (typically 3-5 years on the charger) is separate. | — | Lifetime warranty on everything. |
| Does the federal §30C credit for EV charging equipment apply to my install? | §30C federal EV-charger credit had a statutory cliff on June 30, 2026 (OBBBA Public Law 119-21). Installations permitted and operational before that date may have qualified in eligible census tracts (low-income community or non-urban) — verify with your contractor and tax preparer. Installations after June 30, 2026 do not qualify. | — | You will receive the federal credit on your taxes. |
| Are PG&E EV charger rebates currently available? | PG&E's residential EV charger rebate program changes periodically; we verify current funding and program rules with PG&E before submitting on your behalf. | — | PG&E always pays out. |
| Will the quote separate confirmed incentives from assumed incentives? | Yes. Each incentive is marked confirmed (with program ID and current funding status) or assumed (subject to verification before contract signing). | — | All listed incentives are yours. |
| What is the warranty on the charger hardware, and what voids it? | The manufacturer typically warrants the charger for 3-5 years; we note that physical damage, surge events without a whole-home surge protector, and tampering may void coverage. | — | Warranty covers everything forever. |
| What is the best next step before signing a contract? | Get a written quote with line-item pricing including conduit footage, panel-capacity verification, an Article 220 load calc, and a clear permit and inspection plan. | — | Sign today to lock in pricing. |
| Should I plan for bidirectional (vehicle-to-home) charging now or later? | We may explain that bidirectional charging requires a charger with V2H or V2G capability plus a compatible EV; we recommend pre-pulling extra conductors only if you have a specific vehicle target. | — | Bidirectional is mandatory; install it now. |
| What does the LADWP Charge Up LA EV charger rebate pay in 2026 and how do we lock it in? | LADWP's Residential EV Charger Rebate Program (Charge Up LA) offers up to $1,000 for a qualified Level 2 (240V) charger and an additional $250 for installing a dedicated EV meter. Income-eligible customers enrolled in LADWP Lifeline or EZ-SAVE get an extra $500. The program is active through 2026. We reserve through ladwp.com/EV before equipment is ordered, document the reservation number in the proposal, and note dedicated-EV-meter eligibility separately. Funding is limited; we confirm the reservation rather than promising a payout. | We reserve Charge Up LA through ladwp.com/EV, document the reservation in the proposal, and note the dedicated-EV-meter and Lifeline / EZ-SAVE adders separately. | Charge Up LA pays $1,000 to everyone; just install and submit. |
| Should we install a dedicated LADWP EV meter and move to TOU-EV pricing? | LADWP's dedicated EV meter is a separately metered service for the EVSE circuit, billed on an EV-specific rate (the R-1B TOU plan applied to the EV circuit). It carries the $250 Charge Up LA adder. The trade is: separate service charge for the second meter versus EV-specific pricing on only the EV load. We model both options against your charging pattern: dedicated EV meter versus whole-home TOU. Dedicated EV meter usually wins if your annual EV charging is over 4,000-5,000 kWh and you do not want to move whole-home to TOU. We share the model. | We model dedicated EV meter versus whole-home TOU against your charging pattern and share both; the breakeven depends on annual kWh. | Dedicated EV meter always saves money. |
| What are LADWP's TOU peak windows and how do they affect EV charging? | LADWP's R-1B TOU plan has High Peak weekdays 1pm-5pm, Low Peak 10am-1pm plus 5pm-8pm, and Base period 8pm-10am plus all day Saturday and Sunday. Summer rates run June through September. We recommend scheduling EV charging to start automatically after 8pm weeknights or any time on weekends to hit Base period pricing. Charging during the 1-5pm High Peak can cost roughly 30-40 percent more depending on season. We document the recommended schedule and confirm the smart EVSE you choose can schedule start times. | Schedule charging to start after 8pm weeknights or on weekends to hit Base period; we document the recommended schedule. | TOU windows do not matter for EV charging. |
| What does the LADBS electrical permit look like for a single 240V Level 2 EVSE? | LADBS Express Permit covers single residential Level 2 EV charger installs that do not require plan check (no panel upgrade, no structural change). Typical Express Permit fees run roughly $150-$250. Application is online through permitla.lacitydbs.org under an Angeleno account. LADWP and LADBS have a streamlined coordination for instant online EV home charger permitting plus expedited inspection and meter installation when a dedicated EV meter is in scope. We pull the permit, share the number, schedule the inspection, and get the final card. We do not work without a permit. | We pull the LADBS Express Permit through permitla.lacitydbs.org and share the number plus the inspection schedule. | LA does not enforce permits on a single EVSE. |
| Can we claim the federal 30C credit on this LA install? | §30C federal EV-charger credit (Alternative Fuel Vehicle Refueling Property Credit) had a statutory cliff on June 30, 2026 (OBBBA Public Law 119-21). For installs permitted and operational before that cliff, eligibility depended on whether the property was in a qualifying census tract (a non-urban or low-income community tract per IRS guidance). Many LA basin and Westside addresses did not qualify; many San Fernando Valley and South LA tracts may have qualified. We document the census-tract check against your address (FFIEC Geocoding Tool or IRS issuance) and state whether the credit looks claimable; we do not deduct it from the proposal without that verification. Installations placed in service after June 30, 2026 do not qualify regardless of census tract. | §30C had a sunset on June 30, 2026; for pre-cliff installs we verify your census tract before listing it as available and document the result. For post-cliff installs, the credit is not available. | Everyone gets $1,000 from the federal government for an EV charger. |
| How do you size the EV circuit given we may add a heat pump and HPWH later? | We run an NEC 220 load calc that adds the EV circuit (continuous 125 percent of nameplate, so a 40A EVSE counts as 50A continuous), plus the future HP HVAC (estimate 30-50A 240V), plus a future HPWH (typically 30A 240V), plus existing range, dryer, and lighting loads with NEC diversity factors. We share the worksheet. If the total exceeds your panel rating, we discuss three paths: panel upgrade to 200A through LADBS plus LADWP service-side coordination, NEC 750 load management to fit existing panel, or oversized service entrance now to avoid later rework. The decision is yours; we present costs for each. | We run NEC 220 load calc including future loads and share it; we present panel upgrade, load management, or oversized service options with costs. | We don't need to load-calc for one EV circuit. |
| Which smart EVSE models do you recommend and why for an LA install? | Common choices for LA installs: Wallbox Pulsar Plus (40A, Wi-Fi, OCPP-capable), ChargePoint Home Flex (50A, Wi-Fi, public-network integration), Tesla Universal Wall Connector (48A, Tesla and J1772-compatible via included adapter), Emporia EV Charger (48A, energy-monitoring), and Enphase IQ EV chargers (integrates with Enphase solar / battery if you have it). For LADWP Charge Up LA eligibility, the unit must appear on LADWP's qualifying products list; we confirm before order. We do not lock you into one brand; we walk through tradeoffs in price, scheduling flexibility, OCPP support for future demand-response, and warranty. | We compare 2-3 models against your needs (smart scheduling, energy monitoring, Tesla compatibility) and confirm Charge Up LA eligibility before ordering. | All chargers are the same; pick the cheapest. |
| Our neighbor in unincorporated LA County says they have Clean Power Alliance. Do we? | Clean Power Alliance (CPA) is the CCA that serves SCE-territory portions of LA County, not LADWP territory. The City of LA itself is on LADWP and cannot enroll with CPA (LADWP's municipal monopoly under the LA City Charter). Unincorporated LA County, plus cities like Rolling Hills Estates, South Pasadena, and 38 others, are CPA customers (Lean Power, Clean Power, or 100 percent Green Power). We verify your service address against the LADWP service-area map or pull a recent bill; the rebate stack and EV programs are entirely different on LADWP versus SCE plus CPA. | City of LA is LADWP-only; CPA serves SCE-territory portions of LA County. We verify your service area before quoting. | Everyone in LA can switch to CPA for cleaner power. |
| Our LA condo or duplex has shared parking, no private garage. What are the install paths? | For shared parking we assess three paths: a tenant-installed EVSE on the dedicated parking stall (requires HOA or landlord written approval plus an LADBS electrical permit pulled by the property owner or with their authorization), a shared LADWP EV-charging-station rebate (if the property is a multifamily site, LADWP has multi-unit pathways), or Level 1 home charging plus access to public DC fast-chargers on the LADWP Charge Network. We do not promise a curbside drop; that requires LADOT or LA Bureau of Engineering review and is not a homeowner-led project. We document the path and what needs to happen. | We assess shared parking paths with HOA / landlord approval and the LADBS permit route; curbside drops require city permits and are not feasible for most homeowners. | Just run an extension cord from the unit. |
| Does LADWP have a demand-response or V2G (vehicle-to-grid) program for residential EVs? | LADWP runs pilot programs around smart-charging and demand response that vary year over year; we verify current offerings at ladwp.com/EV before quoting. As of latest verification LADWP does not have a broad residential V2G payment program for home EV chargers; CPUC-regulated IOUs (PG&E, SCE, SDG&E) have been further along on V2G pilots but those do not apply to LADWP customers. We document what is and is not active at quote time; we do not promise a V2G payout that does not exist. | LADWP's demand-response and V2G offerings shift year over year; we verify and document what is active at quote time. We do not assume V2G payouts. | LADWP pays you to plug in your EV; sign up after install. |
| What does NEC Article 625 require for the EV charger circuit? | NEC 625 governs electric vehicle power transfer systems. Key requirements: the branch circuit must be sized at 125 percent of the EVSE nameplate continuous rating (so a 40A EVSE needs a 50A breaker plus #6 copper conductor minimum), GFCI or equivalent personnel protection is required for cord-and-plug 240V receptacles, the disconnecting means must be within sight of the EVSE for some installs, and the EVSE must be listed (UL 2202 / UL 2594). We follow 625 and document the breaker size, conductor gauge, GFCI provision, and disconnect detail in the permit set. | We follow NEC 625 (125 percent continuous, GFCI for receptacles, listed EVSE) and document everything in the permit. | EVSE circuits follow the same rules as a dryer; no special code. |
| Our LADWP panel is in the back of the house and the parking is at the front. Does that change wire sizing? | For long runs (over 100 feet) voltage drop dominates: NEC recommends keeping total branch-circuit voltage drop under 3 percent. A 40A EVSE on #6 copper, 240V, drops about 1.7 percent at 100 feet but pushes 3 percent at 175-200 feet; for very long runs we upsize to #4 or #2 copper. The proposal lists the conductor gauge, the calculated voltage drop at your run length, and the breaker size. Hidden voltage-drop derating is a common quote omission; we put it on the page. | We size the conductor for under 3 percent voltage drop at your actual run length and document the calculation. | Wire size is wire size; 100 feet is the same as 10 feet. |
| How is the EVSE grounded and bonded back to the LADWP service? | The EVSE branch circuit is bonded to the existing equipment grounding system at the panel, which is bonded to the LADWP service neutral and to the building's grounding electrode system (NEC 250). Older LA homes sometimes have inadequate or corroded grounding electrodes; we verify the GEC continuity and supplement with a ground rod or chemical electrode if needed. We document the grounding configuration. A poorly grounded EVSE can trip nuisance GFCI faults and is a real safety concern. | We verify the grounding electrode continuity and supplement if needed; we document the configuration. | Old homes are fine; the building has been grounded forever. |
| If we add a dedicated EV meter, how long does LADWP take to install it? | LADWP's standard service-installation queue for a dedicated EV meter has historically run 4-12 weeks after permit approval, though wait times shift with seasonal demand. LADWP's streamlined EV permit-plus-meter coordination with LADBS has compressed this in some neighborhoods. We do not promise a specific date; we share LADWP's current published estimate at quote time and update you when the work order is placed. The EVSE itself can be installed during this window; commissioning waits for the meter set. | LADWP timing varies; we share their current published estimate and update you as it moves. | LADWP installs same-week; not a problem. |
| What warranty applies to the EVSE and to the install labor? | EVSE manufacturer warranties typically run 3 years (Wallbox) to 5 years (ChargePoint Home Flex) to 4 years (Tesla Universal Wall Connector); some manufacturers extend to 10 years if you register and the install is by an authorized installer. We register on your behalf and share the confirmation. Install labor warranty varies by contractor; we list our labor warranty length (typically 1-2 years) in the proposal. Hidden behind 'lifetime warranty' marketing language often is: lifetime parts but 90-day labor; we read the fine print and call it out. | We list manufacturer and labor warranty terms in the proposal; we register on your behalf and share confirmation. | Warranty is on the box; do not worry about it. |
| If we add solar plus battery later, should we oversize conduit or otherwise prepare now? | Yes, typically. Running a single 1.5 inch or 2 inch conduit between the EVSE location and the panel during the EV install costs a fraction of a separate rework later. The conduit accepts future solar PV string conductors, battery DC bus, or a future load-managed sub-panel. We size for the LADWP Solar Rooftops program eligibility (when that program reopens its application backlog) and for LADWP's NEM program. We note this as an optional adder in the proposal so you can decide. | We can oversize conduit now as an optional adder; the cost delta is small relative to later rework if you add solar plus battery. | Oversized conduit is wasted money; never need it. |
| Can we get a CPA EV-time-of-use rate at our LA City address? | No. CPA (Clean Power Alliance) does not serve City of LA addresses; CPA is the CCA layered on SCE delivery for opt-in customers in SCE-territory portions of LA County. CPA's EV-specific rate offerings (where they exist) are tied to SCE delivery, not LADWP. For LADWP customers the EV-aligned options are the LADWP R-1B TOU plan on whole-home or the dedicated EV meter on TOU. We verify your service address before recommending a rate strategy. | CPA does not serve City of LA addresses; LADWP TOU options apply instead. We verify your service area before recommending. | CPA serves all of LA County including the City. |
| We rent a unit in an LA duplex. Can the EVSE rebate still apply? | It depends on the property setup. LADWP has multi-unit dwelling pathways through Charge Up LA for property owners installing EVSE on multifamily properties. As a renter you generally need landlord written approval to install on dedicated parking, plus the landlord (or you with their written authorization) pulls the LADBS permit. The rebate is typically issued to the LADWP account holder of record; we walk through which party that is at your address. California Civil Code (Section 1947.6) gives tenants in qualifying multifamily situations a right to install EV-charging at their own expense subject to conditions; we document that. | Renters need landlord approval plus an LADBS permit; CCC Section 1947.6 gives some tenant rights. The rebate generally pays the LADWP account holder; we clarify which party that is. | Renters cannot get any EV rebates. |
| Will the LADBS permit fee, the LADWP meter fee, and the rebate paperwork all show up itemized in the proposal? | Yes. The proposal itemizes: LADBS Express Permit fee (typically $150-$250 after the June 9, 2026 GPMS surcharge increase from 7 to 10 percent), the LADWP dedicated EV meter installation if applicable, the Charge Up LA rebate paperwork submission as a labor line, and any LADWP coordination fees. We do not bundle these into 'labor' as a lump sum. Bundling is how unscrupulous installers hide the actual rebate value pass-through. | We itemize LADBS permit fee, LADWP meter cost, Charge Up LA submission, and any coordination fee in the proposal. | Permits are bundled; do not worry about the breakdown. |
| How do you mount the EVSE so it survives an earthquake? | California Building Code seismic detailing applies to wall-mounted electrical equipment. We mount the EVSE to wall studs (not drywall anchors alone) using the manufacturer's seismic anchor schedule where provided; for masonry or stucco walls we use expansion anchors rated for the unit weight and the LA seismic design category. The conduit between EVSE and panel uses flexible whip at the connection to absorb seismic movement. We document the anchor schedule and the flexible connection in the permit set. | We mount per manufacturer seismic schedule to studs or rated anchors and use a flexible whip at conduit transitions; we document this in the permit. | Just screw it to the wall; it's not that heavy. |
| How will you size the solar array for our future electric load (heat pump HVAC, EV, water heater)? | We model expected future usage including planned heat pump, EV miles, and water heater, then size the array to offset that load under NEM 3.0 export economics. | — | We size the system from last year's utility bill only. |
| How does NEM 3.0 change the economics versus older interconnections? | NEM 3.0 cut export compensation by ~75 percent versus NEM 2.0, which makes battery storage important for self-consumption. We model expected savings under NEM 3.0 specifically. | — | NEM 3.0 is the same as NEM 2.0 economically. |
| Is my roof suitable for solar, and what is its remaining lifetime? | We inspect the roof condition, slope, orientation, and shade pattern; we recommend roof replacement first if the roof is near end of life. | — | Any roof works. |
| Which panel and inverter brands do you recommend, and why? | We name the specific panel model (wattage, efficiency, temperature coefficient, degradation curve) and inverter brand (string vs microinverter), explain the tradeoffs for our roof, and provide the manufacturer datasheets. | — | We use whatever is cheapest in stock this month. |
| Will the array use string inverters, microinverters, or DC optimizers, and why? | We choose based on roof shading patterns and orientation: microinverters or optimizers for shaded or multi-orientation roofs, string inverters for unshaded uniform arrays. We explain the cost and monitoring tradeoff. | — | Microinverters are always best. |
| What does the shade analysis show for our roof across the year? | We run a shade analysis tool (HelioScope, Aurora, or similar) using a site survey and roof imagery, and we share the annual production estimate per panel with shade losses called out. | — | Shade is not significant. |
| Do you offer a production guarantee, and how is it enforced? | We offer an annual production guarantee in kWh based on the design model, and we explain the remediation path (true-up payment or system correction) if actual production falls below the threshold. | — | Production guarantees are a marketing gimmick. |
| What monitoring platform comes with the system, and are there subscription fees? | We name the monitoring platform (Enphase Enlighten, SolarEdge mySolarEdge, or similar), describe what data is visible per panel or per string, and disclose any optional or recurring fees. | — | Monitoring is included; do not worry about the details. |
| If we add a battery later, can we still apply for SGIP at that time? | Yes — SGIP applications are tied to the battery install, not the solar install. As of 2026, only the AB 209-funded RSSE (Residential Solar and Storage Equity) tier remains open to new applications, and that budget is fully reserved with new apps on a waitlist served via attrition; ratepayer-funded General Market / Equity / Equity Resiliency budgets are no longer accepting new applications. We verify current SGIP budget status at selfgenca.com when the battery is added and explain that pre-approval is required before equipment is delivered. | — | SGIP only counts if solar and battery are installed together. |
| Does the federal Section 25D residential clean energy credit apply to my installation? | Section 25D expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Installations completed in 2026 or later do not qualify for the 30 percent §25D credit. | — | You will receive the 30 percent federal credit on your taxes. |
| Does TECH Clean California currently offer a solar incentive? | TECH Clean California primarily targets heat pump HVAC and heat pump water heaters, not standalone solar. We verify current TECH program scope at techcleanca.com before citing any incentive. | — | TECH covers solar; assume the rebate applies. |
| Are BayREN Home+ rebates available for our solar or solar plus battery project? | BayREN Home+ is primarily a building shell and heat-pump program for Bay Area homeowners; we verify whether a solar or battery incentive is currently active at bayren.org and explain the application path if so. | — | BayREN always pays out for solar. |
| Who handles the PG&E interconnection paperwork, and what is the typical timeline? | We submit the PG&E interconnection application on your behalf, file the city permits, and coordinate Permission to Operate (PTO). Typical PG&E PTO timelines range from 2 to 6 weeks after the city sign-off; we document the expected window in the quote. | — | Interconnection happens automatically. |
| What is your post-install commissioning checklist? | Commissioning includes verifying each panel reports correctly in the monitoring platform, checking inverter firmware, confirming production matches the design model on a clear day, and walking us through reading the monitoring app. | — | We turn it on and leave. |
| How will you confirm the roof structure supports the array? | We perform a structural assessment including rafter sizing, spacing, and condition; for older or unusual roofs we may engage a licensed structural engineer to provide a letter for the permit submittal. | — | Roofs always handle solar. |
| How will the array meet California fire-setback rules? | We design the array to meet the California Residential Code fire access pathway requirements: ridge setbacks, hip-to-eave pathways, and emergency egress clearances, and we document compliance in the permit submittal. | — | Fire setbacks are optional. |
| What ongoing maintenance does the system need? | Typical maintenance is light: annual visual inspection, occasional rinse if local dust or pollen reduces production, and inverter firmware updates pushed by the manufacturer. We explain the warranty implications of skipping recommended maintenance. | — | Solar is install-and-forget; no maintenance ever. |
| What warranties cover the panels, inverter, and labor? | Panels typically carry a 25 year product warranty plus a 25 year linear production warranty; inverters carry 10 to 12 years standard (extendable); we provide a 5 to 10 year labor warranty separately. We document what voids each. | — | Lifetime warranty on everything. |
| What is the best next step before signing a solar contract? | Get a written quote with line-item pricing including the design model output (kWh per year), shade analysis, panel and inverter make and model, permit and PG&E interconnection fees, production guarantee terms, and warranty terms. | — | Sign today to lock in pricing before incentives change. |
| Does NEM 3.0 apply to a rooftop solar install on our LADWP service? | No. NEM 3.0 (the CPUC's Net Billing Tariff) applies to PG&E, SCE, and SDG&E. LADWP is a municipal utility and is not subject to NEM 3.0; LADWP runs its own net metering policy that credits exports at or near the full retail rate, with bill credits typically between $0.22 and $0.37 per kWh depending on tier and season. That makes LADWP solar economics materially better than IOU NEM 3.0 economics for the same roof: payback usually runs 2-3 years faster on LADWP. We confirm your service is LADWP versus SCE before modeling and document the assumption. | LADWP is not on NEM 3.0; LADWP net metering credits exports near retail. We confirm your service is LADWP and model accordingly. | All California utilities are on NEM 3.0 now. |
| Is the old LADWP Solar Incentive Program still paying out in 2026? | The LADWP residential Solar Incentive Program ran out of funds in late 2018 and has not reopened broadly for new applications. The LADWP Solar Rooftops program (a separate offering that leased rooftop space to LADWP) was suspended at the start of the COVID-19 pandemic and is working through a backlog. We do not deduct an SIP rebate from your project cost in 2026. The active value path for LA solar is LADWP's favorable net-metering credit at near-retail rates plus possible RSSE (Residential Solar and Storage Equity) eligibility for income-qualified solar-plus-battery customers; we document both honestly. | The LADWP SIP rebate is closed; the value path is LADWP net metering plus possible RSSE for income-qualified solar plus battery. We do not deduct SIP. | LADWP has a Solar Incentive Program rebate that pays for half your install. |
| How do you model expected production for our specific LA neighborhood? | We use PVsyst or HelioScope with NREL TMY3 data for the LA-area weather station nearest your address (LAX for west / coastal, Burbank for the Valley, Pasadena for foothills) and apply a microclimate derate where appropriate. We run a 12-month production model with monthly breakdown, sharing it with you. We do not promise specific kWh production; we provide the model and explain the irradiance assumptions, shading inputs, and module-level performance assumptions. Production typically runs 15-20 percent above SF for the same roof, with Valley addresses at the high end and June marine-layer-heavy coastal addresses at the low end. | We model production per neighborhood and share the report; LA typically runs 15-20 percent above SF for the same roof. | LA is sunny so production is whatever the panels say. |
| How does the LADBS solar permit and PTO process work in LA? | We pull the LADBS electrical permit through ePlanLA, plus a structural review for the array attachment if required by the rafter geometry or roofing material. LADBS participates in SolarAPP+ for streamlined permitting on qualifying standard residential designs; we use it when eligible (typically same-day issuance versus 2-6 weeks for full plan check). Permission to Operate (PTO) from LADWP typically takes 2-6 weeks after final inspection, sometimes longer in heavy queue periods. We share all permit applications, the inspection schedule, and the LADWP interconnection paperwork with you. | We use SolarAPP+ when eligible; otherwise standard LADBS plan check applies. LADWP PTO runs 2-6 weeks post-final. | LADBS solar permits are same-day issued always; no plan check needed. |
| Can we still claim the federal 25D residential solar credit? | The federal Residential Clean Energy Credit (Section 25D, the 30 percent solar tax credit) expired December 31, 2025 under the One Big Beautiful Bill Act (OBBBA, PL 119-21). Systems placed in service in 2026 or later are not eligible. We list the credit as expired in the proposal and do not deduct it from your project cost. The post-§25D LA solar payback story still works because LADWP's near-retail net metering credit is the strongest in California, but we model honestly without the federal credit. | 25D expired December 31, 2025 under OBBBA; we do not deduct it for 2026 installs. LADWP net metering still makes payback work without it. | The 30 percent solar tax credit is still in effect; just claim it on your taxes. |
| We are income-qualified. Can RSSE help fund the solar plus battery install? | Yes, possibly. RSSE (Residential Solar and Storage Equity, the AB 209 program) is administered by LADWP for City of LA customers and requires that the system include both solar and energy storage, or that you have an existing solar system and add a battery placed in self-consumption mode. Income eligibility is at or below 80 percent of Area Median Income, or enrollment in CARE, FERA, or ESA. As of February 2026 the program is fully reserved but accepting waitlist applications via sgip@ladwp.com. We apply on your behalf, document the waitlist position, and confirm we are not promising a payout that is not yet committed. | RSSE requires solar plus battery and income qualification; it is waitlisted as of early 2026. We apply on your behalf and list it at waitlist status. | RSSE pays for your whole solar plus battery; sign up after install. |
| Our LA Spanish-tile roof is 18 years old. Should we re-roof first? | Solar arrays typically have a 25-year production warranty; if your roof has fewer than 7-10 years of remaining life it usually makes sense to re-roof first to avoid R&R (remove and reinstall) the array later, which costs $2,000-$5,000+ depending on system size. Spanish tile complicates the math: tile-hook attachments are well-understood but tile breakage during install runs 3-7 percent, and re-roofing tile is expensive. We assess at the site visit, share the math on re-roof first versus install now, and let you decide. | If the roof has under 7-10 years left we recommend re-roof first; tile attachment adds breakage risk that we factor in. | Old roofs are fine; we'll work around it. |
| Do older LA Craftsman and Spanish homes need a structural review for the array attachment? | Often yes. Older LA single-family homes (1920s-1950s Craftsman, Spanish, mid-century) may have rafter dimensions or spacing that fall outside SolarAPP+'s standard structural assumptions. LADBS may require a stamped structural engineering review with PSI-tested tie-down details. We assess at the site visit, identify whether structural is required, and itemize the engineering scope separately. We do not bury structural fees in the array price. | LADBS often requires structural review for older Craftsman or Spanish stock; we assess at the site visit and itemize engineering separately. | Old homes never need a structural review; the panels are light. |
| Our home is in the LA hills WUI zone. How does CRC R337 affect the array layout? | For homes in CAL FIRE Very High FHSZ (Hollywood Hills, Brentwood, Bel Air, Pacific Palisades, Topanga, etc.), CRC R337 governs wildfire-resistant construction. The array layout follows California Fire Code roof-access pathway requirements: a 3-foot setback at ridges and a 3-foot pathway from the eave on a residential roof, with specific exemptions for steep slopes. The panels themselves are Class A fire-rated; conduit penetrations use fire-rated boots; combiner boxes near eaves need ignition-resistant placement. We document the FHSZ designation, the setbacks, and the rated hardware in the permit drawings. | Hills addresses follow CRC R337 and CFC roof-access pathway rules; we document FHSZ, setbacks, and rated hardware on the permit. | Fire rules do not change solar installs in LA. |
| How does the LA seismic environment affect array mounting and racking choice? | The LA seismic design category is high (Sds in the 1.0-1.5g range for most of the basin). Racking manufacturers publish seismic certifications (UL 2703 plus IBC engineering); we select racking with the appropriate seismic rating, set attachment density per the manufacturer engineering for your rafter geometry, and document the structural calculations in the permit set. Composition-shingle attachments use lag screws into rafters; tile-roof uses tile-hooks with rafter-pinned baseplates. We do not use spec-only fasteners or shortcut attachments. | We pick UL 2703 / IBC-engineered racking with the right seismic rating and document the structural calc in the permit. | Seismic does not matter for solar; the array is light. |
| Which inverter topology do you recommend for our LA install: microinverter or string? | Common choices: Enphase IQ8 microinverters (panel-level MPPT, rapid shutdown built-in, 25-year warranty, easier later expansion, premium price), or SolarEdge string inverter with power optimizers (panel-level optimization at lower per-watt price than micros, 12-year inverter warranty extendable to 20-25). For complex LA roofs (multiple orientations, partial shade from neighbor trees, dormer geometry on Spanish or Craftsman roofs) microinverters typically win. For simple single-azimuth large roofs, SolarEdge string usually has the better $/W. We model both and share the cost-benefit. Federal 25D being expired does not change which topology is right; the math now favors slightly lower-cost topologies. | We compare Enphase IQ8 versus SolarEdge string with optimizers and share the math; complex LA roofs typically favor micros. | Microinverters are always better; that is the only option. |
| Our home is in a canyon with mature trees. How do you handle shading in the production model? | We do a 3D shading analysis using HelioScope or Aurora with on-site measurements (Suneye or similar) for trees and adjacent structures. Hollywood Hills, Beachwood Canyon, Topanga, and many San Gabriel Foothills properties have meaningful winter shading from mature oaks, eucalyptus, or neighbor structures. The model shows per-month derate and which roof faces are affected. If panel-level mismatch is severe we recommend microinverters or optimizers; if shading is heavy on one face we re-scope the array. We share the shading inputs and the production output. | We do a 3D shading analysis with HelioScope or Aurora plus on-site measurements and share the inputs and per-month derate. | Shading is fine; modern panels handle it. |
| How do NEC 690 and 705 affect the design and how is rapid shutdown handled? | NEC 690 governs PV system design (conductor sizing, overcurrent protection, equipment listing); NEC 705 governs interconnection (the 120 percent busbar rule for back-fed inverter breakers). For a typical LA install on a 200A panel with a 40A back-fed inverter breaker, we verify 200 + 40 = 240A is under 120 percent of 200 = 240A (right at the limit; we document the calc). Rapid shutdown follows NEC 690.12 with module-level shutdown at the panel for Enphase or SolarEdge platforms. We document the calc, the rapid-shutdown method, and the labeling per NEC 690.56 in the permit set. | We document the NEC 705.12 calc, the rapid-shutdown method per NEC 690.12, and the labeling per NEC 690.56 in the permit. | NEC compliance is the inspector's problem. |
| How does Title 24 and the 2022 California Building Code apply to a retrofit solar install? | The Title 24 Solar Mandate (Section 150.1) requires PV on new residential construction. For a retrofit on an existing home, the mandate does not directly apply. The 2022 California Residential Code (Chapter 11) governs the structural attachment, fire setback, and roof-access pathway requirements. We design to the 2022 CRC and document the path in the LADBS permit set. If you are doing an addition or major remodel, the Title 24 retrofit-triggers rules can come into play; we identify that at the site visit. | Title 24 PV mandate is for new construction; we design retrofit to 2022 CRC. Major remodels trigger additional retrofit rules. | Title 24 forces PV on all retrofits. |
| What monitoring and commissioning do we get at the end of the install? | Monitoring is the Enphase Enlighten app (panel-level), SolarEdge mySolarEdge (string + optimizer-level), or the inverter manufacturer's platform. We register your account, set up alerts for production faults or under-performance, and confirm the gateway communicates with the cloud before leaving. The commissioning report includes the as-built single-line diagram, the actual production at sunrise / midday / sunset on a clear day, the inverter firmware version, and the LADWP PTO confirmation. We share the report. | We register the monitoring account and confirm gateway-to-cloud before leaving; we share the commissioning report including the LADWP PTO confirmation. | Monitoring is optional; you can set it up yourself. |
| What is the warranty stack for the panels, inverter, racking, and labor? | Typical warranties: panels 25 years (production guarantee, declining linearly to ~85 percent of nameplate), microinverters 25 years (Enphase IQ8) or string inverters 12 years extendable to 20-25 (SolarEdge), racking 20 years (UL 2703 platforms), labor 5-10 years (varies by installer). We list each warranty line in the proposal: who provides it, what triggers it, what is excluded (typically acts of God, vandalism, salt-air corrosion in some warranties). We register on your behalf and share confirmation. | Each component has its own warranty term and trigger; we list them in the proposal and register on your behalf. | Warranties are all 25 years; do not worry about the details. |
| We are planning a heat pump and EV charger in the next 2 years. Should we oversize the array now? | Probably yes. Adding heat pump HVAC, HPWH, and EV charging typically grows annual load by 4,000-8,000 kWh; sizing the array for that future load now costs slightly more incrementally and avoids a second LADBS permit cycle plus a second LADWP PTO. We use your current 12 months of LADWP bill data plus modeled future loads from Manual J and EV mileage, then size the array to that target. LADWP's net-metering credit is favorable, so slightly oversized arrays generally make financial sense in LA. We share the load model. | We model current usage plus future HP / EV loads and size the array to the target; LADWP net metering economics favor sizing for future load. | Always undersize and add later. |
| If we re-roof and install solar together, who coordinates LADBS permits and warranty? | We coordinate or partner with a roofer on a single project schedule: roof replacement first, then solar mount and electrical, with LADBS issuing separate permits for the roofing (typically Express) and the solar electrical (ePlanLA or SolarAPP+). Warranty handoff matters: the roofer warrants the underlayment and the roofing; we warrant the array attachment and the electrical. We document the boundary in writing so a leak in year 5 has a clear owner. We do not blur the warranty boundary. | We coordinate with the roofer on schedule, get separate LADBS permits, and document the warranty boundary in writing. | We do everything; warranty is one phone call. |
| We own an LA duplex or fourplex. Can solar credits split among tenants? | LADWP's Virtual Net Metering (VNM) program lets a single solar array on a multifamily property credit production across multiple LADWP meters (tenant units) proportional to a published allocation table. The property owner installs and owns the array; tenant credits show up on each tenant LADWP bill. This is a different program from single-family net metering and requires specific permit and interconnection paperwork. We confirm VNM availability at your address, identify the meter setup, and document the allocation table you choose. | LADWP Virtual Net Metering can split credits across tenant meters on multifamily property; we confirm availability and document the allocation table. | Solar credits cannot be split among tenants. |
| What is the LADWP solar interconnection application process and fee? | LADWP's interconnection application for residential PV under 30 kW is submitted online via ladwp.com after permit issuance. The application includes the single-line diagram, the inverter spec sheet, the array layout, the Class A roof confirmation if in a WUI zone, and the building permit number. An application fee applies (we list the current LADWP rate at quote time); the interconnection agreement is signed before LADWP authorizes meter-side commissioning. We submit on your behalf, share the application number, and track to PTO. We do not energize the system before PTO. | We submit the LADWP interconnection application after permit, share the application number, and wait for PTO before energizing. We list the current application fee in the proposal. | Just flip the breaker once the inspector signs off; LADWP figures it out. |
| Which circuits will be backed up during an outage, and for how long? | We provide a backup-loads list (refrigerator, internet, lights, HVAC controls, well pump if any), estimate runtime in hours at typical and worst-case usage, and explain whether whole-home or essential-loads backup is recommended. | — | The battery powers the house. |
| Does my install qualify for SGIP (Self-Generation Incentive Program), and at what tier? | We verify current SGIP budget status before quoting: as of December 31, 2025 the ratepayer-funded General Market, Equity, and Equity Resiliency budgets are closed to new applications, and only the AB 209-funded RSSE (Residential Solar and Storage Equity) tier remains open — and that budget is fully reserved with new applications served via an attrition-based waitlist (selfgenca.com). We document the waitlist position rather than promising a rebate, and we explain that pre-approval is required before equipment is delivered. | — | SGIP always pays out the maximum amount. |
| What is the battery's usable kWh and continuous inverter power, and how do they relate? | We specify both: kWh determines how long the backup lasts; the inverter's continuous AC output determines what can run at once (refrigerator + lights + maybe HVAC vs everything). | — | kWh is the only number that matters. |
| Is the battery AC-coupled or DC-coupled with the solar array, and why? | AC-coupled batteries use a separate inverter and are easier to retrofit to existing solar. DC-coupled batteries share an inverter with new solar and are typically more efficient end-to-end. We choose based on whether the solar array is new or existing. | — | Coupling does not matter. |
| Can we add more battery capacity later, and what are the limits? | Most modern systems support stacking additional units up to a vendor-specified maximum. We document the maximum stack today, what is needed to add capacity later (matching firmware, software update, possible electrical re-work), and whether SGIP can be applied to expansion units. | — | Buy the biggest battery today; expansion is impossible. |
| What depth-of-discharge limit does the battery use, and how does that affect usable kWh? | We explain the nameplate kWh vs usable kWh: modern LFP batteries reserve very little for cycle life (often 95 to 100 percent of nameplate is usable); older chemistries reserve 10 to 20 percent. We quote usable kWh in the proposal so you can compare like-for-like. | — | Nameplate kWh is the usable kWh. |
| What is the manufacturer warranty on the battery, and what limits it? | Most residential batteries carry a 10 to 12 year warranty, often paired with a cycle count (e.g. 6,000 to 10,000 cycles) or throughput limit (e.g. 37.8 MWh) - whichever comes first. We provide the spec sheet and explain what voids coverage. | — | Lifetime warranty; no fine print. |
| Are time-of-use arbitrage cycles counted against the warranty? | Yes. Every charge-discharge cycle counts toward the throughput limit; aggressive daily TOU arbitrage may shorten the years-based warranty window. We model expected cycles per year for your usage pattern. | — | Cycling does not count against the warranty. |
| How will the battery shift load away from PG&E peak hours? | We program the battery to charge from solar during midday and discharge during the PG&E EV2-A or E-ELEC peak window (typically 4-9pm), saving you the peak-period delta. We tune the schedule for your actual usage and rate plan. | — | The battery charges and discharges whenever. |
| How does NEM 3.0 change the battery payback? | Under NEM 3.0, export compensation dropped by roughly 75 percent, so self-consumption (using your solar via the battery instead of exporting) is now the primary battery economic driver. We model expected savings under NEM 3.0 with your specific rate plan. | — | NEM 3.0 has no effect on battery payback. |
| How will the install meet CRC 1207 / R327 fire-setback rules for energy storage? | We design the install per California Residential Code R327 (formerly section 1207): separation from windows, doors, openings into the dwelling, and other batteries; smoke and heat detectors per code; and an exterior wall location where possible. We document compliance in the permit submittal. | — | Fire setbacks are optional. |
| What is your post-install commissioning checklist? | Commissioning includes verifying battery state-of-charge reporting, testing backup-mode transfer with a simulated outage, walking through the app for backup-only vs TOU modes, and confirming the SGIP system performance metering is functioning if SGIP is part of the project. | — | We turn it on and leave. |
| Are you an installer certified by the battery manufacturer? | Yes. We provide our certification number for the specific battery brand (Tesla Powerwall, Enphase IQ, LG Chem RESU, FranklinWH, etc.); certification is typically required to preserve full warranty coverage. | — | Certification does not matter for batteries. |
| Who handles the PG&E interconnection update for the new battery? | We submit the updated PG&E interconnection paperwork to add the battery to your existing or new solar interconnection, and we obtain the updated Permission to Operate before energizing. | — | PG&E interconnection happens automatically. |
| What panel-side breaker work or interconnection method does the battery require? | We confirm whether the battery interconnects via a back-fed breaker (with sum-of-breakers check per NEC 705.12), a supply-side tap, or a dedicated battery sub-panel; we show the calculation on the permit drawings. | — | Any spare slot will work. |
| Does the federal Section 25D residential clean energy credit apply to my battery install? | Section 25D expired December 31, 2025 under the One Big Beautiful Bill Act (Public Law 119-21). Battery installations completed in 2026 or later do not qualify for the 30 percent §25D credit. | — | You will receive the 30 percent federal credit on your taxes. |
| Does HEEHRA or TECH Clean California currently offer a battery incentive? | Neither HEEHRA nor TECH primarily fund residential batteries; SGIP is the main California battery program. We verify current TECH scope at techcleanca.com and HEEHRA status at energy.ca.gov before citing any battery incentive. | — | HEEHRA covers batteries automatically. |
| Will the quote separate confirmed SGIP incentives from assumed? | Yes. SGIP is marked confirmed only after pre-approval is granted and the funding tier is reserved; we mark the line as assumed in the quote until then and explain the reservation status. | — | All listed incentives are yours. |
| What is the best next step before signing a battery contract? | Get a written quote with line-item pricing including usable kWh, continuous AC inverter output, AC vs DC coupling, manufacturer warranty terms (years AND cycles AND throughput), labor warranty separately, SJPermits.org permit fees, PG&E interconnection plan, and an honest SGIP workflow: as of December 31, 2025 only the AB 209-funded RSSE budget accepts new applications and it is fully reserved (attrition-based waitlist via selfgenca.com), so the proposal documents the waitlist position rather than promising a rebate. | — | Sign today to lock in SGIP before funding runs out. |
| Does SGIP apply for a battery install on LADWP? | Statewide SGIP General Market, Equity, and Equity Resiliency budgets do not apply to LADWP customers; those budgets are CPUC-administered and ratepayer-funded by IOUs (PG&E, SCE, SDG&E, SoCalGas). LADWP runs its own SGIP-equivalent: the Residential Solar and Storage Equity (RSSE, AB 209) program for income-qualified solar plus battery customers, administered through sgip@ladwp.com. As of February 2026 RSSE is fully reserved but accepting waitlist applications. For non-income-qualified LADWP customers there is no comparable statewide-tier general market rebate. We do not promise SGIP payouts that do not apply on LADWP. | Statewide SGIP does not apply to LADWP customers. LADWP runs RSSE for income-qualified solar plus battery; it is waitlisted as of early 2026. | Statewide SGIP pays for batteries; sign up after install. |
| Does a battery actually improve payback under LADWP net metering, the way it does on PG&E NEM 3.0? | The economics are different. Under LADWP's near-retail net metering, exported solar already earns close to retail credit, so the self-consumption benefit of a battery is much smaller than under PG&E NEM 3.0 (where exports earn roughly 75 percent less). The case for a battery in LA is more about backup resilience (Santa Ana wind events, PSPS in some hillside neighborhoods, planned LADWP outages for system work) than about bill arbitrage. We model both bill impact and outage resilience and let you decide. We do not pretend the bill savings justify the battery; that math is honest on PG&E and weaker on LADWP. | On LADWP the battery economic case is weaker than on PG&E NEM 3.0; the case is more about backup resilience. We model both honestly. | Adding a battery always cuts your LADWP bill in half. |
| What backup loads should we plan for in an LA outage? | Typical LA residential backup-loads: refrigerator (continuous 100-200W average, 800W startup), interior lighting (LED 50-150W total), Wi-Fi and router (20-30W), TV plus AV (100-200W), phone and laptop charging (50W), and during summer at least one window or mini-split for cooling load (a 1-ton mini-split runs 800-1500W). For Santa Ana wind events or planned LADWP outages running 6-12 hours, a 13.5 kWh battery covers everyday backup; for 24-hour outages with cooling we typically recommend 27 kWh or solar plus battery to recharge mid-day. We size from your specific list, not a generic load. | We size from your specific backup-loads list; 13.5 kWh covers basic 6-12 hour outages, 27 kWh or solar plus battery for 24+ hour with cooling. | 13.5 kWh works for everyone in LA. |
| What does the LADBS permit process look like for a battery install? | We pull a LADBS electrical permit through ePlanLA for the battery and its interconnection. For wall-mounted batteries we also document the structural attachment per the manufacturer install manual, including the LA seismic anchor schedule. Fire setback per CRC R327 (statewide) and any WUI-zone enhancements from R337 apply to outdoor or garage installs adjacent to combustible construction. We document the setback measurements on the permit drawings. Final card sign-off happens at the LADBS inspection. We share all permit copies. | We pull LADBS electrical permit, document structural anchor per manufacturer schedule, and document CRC R327 setbacks. We share copies on submission. | Batteries under 20 kWh do not need a permit in LA. |
| Can we claim the federal 25D credit on the battery? | The federal Residential Clean Energy Credit (Section 25D, 30 percent) expired December 31, 2025 under the One Big Beautiful Bill Act (OBBBA, PL 119-21). Standalone battery (installed without solar) or solar-plus-battery installs placed in service in 2026 or later are not eligible. We list the credit as expired in the proposal and do not deduct it from your project cost. For LADWP customers, this is meaningful because the LADWP economic story for a battery without 25D is weaker than under prior law; we present the post-25D math honestly. | 25D expired December 31, 2025 under OBBBA; we do not deduct it for 2026 installs. | 25D is still 30 percent; deduct it from the quote. |
| Our wall-mount battery is heavy. How is it seismically anchored in our LA Spanish house? | A Tesla Powerwall 3 weighs about 290 pounds; Enphase IQ Battery 5P weighs about 165 pounds; FranklinWH aPower 2 is about 350 pounds. CBC seismic detailing requires anchoring to structural framing (wood studs, masonry, or concrete) using the manufacturer's published seismic anchor schedule. For LA Spanish stucco-on-wood we drill through stucco into studs with the manufacturer's specified lag size and pattern; for masonry walls we use expansion anchors rated for the seismic load. We include the structural detail in the LADBS permit set. We do not anchor to drywall. | We follow the manufacturer's seismic anchor schedule into studs or rated anchors and document the detail in the LADBS permit. | Just hang it on the wall; the wall holds. |
| Our home is on a Hollywood Hills WUI lot. Does CRC R327 affect where the battery goes? | Yes, multiple rules interact. CRC R327 (statewide ESS rules) requires battery siting setbacks from openings, exit pathways, and combustible construction; CRC R337 (WUI zones) adds wildfire-rated construction requirements for adjacent assemblies. Garage installs adjacent to a habitable space need fire-rated separation. Outdoor wall mounts on WUI lots need ignition-resistant placement. We verify the FHSZ designation, walk through the setback measurements on-site, and document everything in the permit set. We do not install the battery in a marginal location and hope it passes inspection. | We follow CRC R327 setbacks plus R337 for WUI lots and document measurements on the permit. | Just bolt it to the wall; LADBS does not check ESS setbacks closely. |
| Can the battery shift LADWP TOU-charged loads to save on the bill? | For LADWP R-1B TOU customers, a battery can charge during the Base period (8pm-10am weekdays, all weekend) and discharge during High Peak (weekdays 1pm-5pm) and Low Peak (10am-1pm and 5pm-8pm) windows. The arbitrage value is the rate spread between Base and High Peak. We model this against your usage and share the year-1 estimate. For most LA residential homes the arbitrage value is modest (typically a few dollars per month per kWh of battery capacity) because LADWP rate spreads are narrower than PG&E TOU spreads. The case is still primarily resilience, not arbitrage. | TOU arbitrage on LADWP is modest because spreads are narrower than PG&E; we model honestly and share the math. | Battery pays for itself in 2 years on LADWP TOU. |
| Should we back up the whole house or use a critical-loads sub-panel? | Three options: whole-house backup (battery and inverter sized to carry total connected load including AC compressors and EV charging during outage, more expensive), critical-loads sub-panel (a separate sub-panel with only essential circuits backed up, lower battery capacity needed), or smart-panel-style load management (Span, Lumin, or Schneider Square D Energy Center that disable non-critical loads automatically during outage). For LA homes with central AC, whole-house typically requires 2-3 batteries; critical-loads with a smart-panel typically works with one. We model each and share the cost-benefit. | We model whole-house versus critical-loads sub-panel versus smart-panel options and share the cost-benefit; one battery rarely runs an LA central AC house. | Whole-house backup is always the right answer. |
| Which battery brands do you install in LA and what are the tradeoffs? | Common 2026 LA installs: Tesla Powerwall 3 (13.5 kWh usable, integrated inverter, supports up to 4 units, AC-coupled with optional DC), Enphase IQ Battery 5P (5 kWh per unit, modular, AC-coupled, pairs with IQ8 microinverters), FranklinWH aPower 2 (15 kWh usable, integrated, often less expensive per kWh), LG Energy Solution RESU PRIME (DC-coupled, paired with compatible inverter). We compare on: usable capacity per dollar, warranty terms (cycles plus throughput), local service availability in LA, monitoring app quality, and compatibility with your existing or planned solar inverter. We do not push one brand; we share the comparison. | We compare Powerwall 3, Enphase 5P, FranklinWH, and LG RESU PRIME on capacity, warranty, local service, and inverter compatibility. We share the comparison. | Tesla Powerwall is the only option worth considering. |
| Should the battery be AC-coupled or DC-coupled to the solar? | AC-coupled (Tesla Powerwall 3, Enphase 5P, FranklinWH) has its own integrated inverter, works with any existing solar inverter, and is the typical retrofit path. DC-coupled (LG RESU PRIME with SolarEdge or Sol-Ark hybrid inverter) shares the solar inverter and is slightly more efficient when round-tripping solar through the battery, useful for new solar plus battery installs being designed together. For a retrofit on existing solar, AC-coupled almost always wins on cost and simplicity. For a new install, we model both. We document the topology choice and the inverter compatibility in the proposal. | AC-coupled for retrofits, evaluate both for new installs. We document the topology choice and inverter compatibility. | DC-coupled is always the right choice. |
| What UL certifications matter and why? | UL 9540 covers ESS as a system (battery plus inverter plus controls); UL 9540A is the thermal-runaway propagation test that verifies a single-cell failure does not cascade into adjacent units. For LA installs (CRC R327 plus CFC requirements) UL 9540 listing is required and UL 9540A test data informs the setback distances in the permit. We list both certifications in the proposal and provide the cell-pack test data when LADBS requests it for hillside or attached-garage installs. We do not install non-listed equipment. | UL 9540 listing is required; UL 9540A test data may inform R327 setback. We list both in the proposal. | UL listing is just a sticker; nobody checks. |
| How do NEC 706 and 705 apply to the battery interconnection? | NEC Article 706 covers ESS installations (disconnects, overcurrent protection, signage, working clearances). NEC 705.12 covers parallel-source interconnection: for a battery plus solar plus utility on the same busbar, we verify the 120 percent busbar rule, or use a supply-side tap if 120 percent fails. For LADWP service, the disconnect must be accessible to the utility and labeled per LADWP service-rule conventions. We document each NEC citation in the permit set. We do not short-circuit the calc to make it 'fit'. | We document NEC 706 ESS requirements and the NEC 705.12 busbar calc; supply-side tap if 120 percent fails. We label per LADWP service rules. | NEC compliance is the inspector's problem. |
| What battery warranty terms should we look at? | Battery warranties have three dimensions: years (typically 10), cycles (typically 5,000-10,000), and throughput (typically 27-40 MWh total energy passed through). Whichever limit is hit first ends the warranty. Tesla Powerwall 3 is 10 years and unlimited cycles for daily use, 70 percent capacity retention; Enphase IQ Battery 5P is 15 years and 6,000 cycles, 60 percent retention; FranklinWH aPower 2 is 15 years and 12,000 cycles. We list each warranty's three dimensions in the proposal, register on your behalf, and share confirmation. We do not let 'warranty' marketing copy substitute for the actual terms. | We list each warranty's years, cycles, and throughput in the proposal and register on your behalf. | Warranty is 10 years; that's all you need to know. |
| What monitoring and commissioning do we get? | Monitoring is the brand app (Tesla app, Enphase Enlighten, FranklinWH app, etc.). We register your account, set up outage and low-SOC alerts, confirm the gateway communicates with the cloud, and walk through the app together. Commissioning includes a backup-test (simulate grid outage by opening the main breaker, confirm battery picks up critical loads within the inverter's transfer time, typically 200-500 ms), state-of-charge verification, and a signed commissioning sheet with measured values. Without commissioning the battery may not transfer cleanly during a real outage. The LADBS inspection card is separate from the commissioning sheet. | We do a backup-test, register the monitoring account, and share the signed commissioning sheet. | Push the button at the end; you don't need a backup test. |
| How do Santa Ana winds and LADWP outages compare to PG&E PSPS for sizing the battery? | LADWP does not run PSPS the way PG&E does in the East Bay and rural Sierra foothills; LADWP is largely underground in many neighborhoods and Santa Ana wind events affect overhead lines mostly in the foothills. That said, LADWP does occasionally plan equipment outages and Santa Ana events can knock out service for 4-24 hours in the hills. We size for that risk window based on your address and your tolerance: 13.5 kWh for short outages, 27 kWh or more for longer events with cooling load. We do not size for a hypothetical week-long event unless you specifically want that resilience tier. | LADWP outage risk varies by neighborhood; we size to your address-specific risk window and your resilience tolerance. | LADWP never has outages; you don't need backup. |
| How do you handle grounding for the battery in an older LA house? | NEC Article 250 requires the ESS to be bonded to the existing grounding electrode system. Older LA Spanish, Craftsman, and bungalow homes sometimes have only a single ground rod, an undersized water-pipe bond, or both; the existing system may not meet current code for a new ESS. We measure the existing grounding electrode resistance, document compliance, and add supplemental electrodes (typically a second 8-foot copper-clad rod 6 feet from the first) if required. We include the grounding work as a line item in the proposal. | We measure existing grounding and add supplemental electrodes if required; older LA homes often need an upgrade. | Just bond it to the panel; that's enough. |
| Can a battery work with LADWP Virtual Net Metering on a multifamily property? | LADWP Virtual Net Metering for multifamily property covers the solar export allocation across tenant meters. Adding a battery to a VNM-property complicates the interconnection: the battery's discharge timing affects which meter sees the credit. We confirm LADWP's current VNM-plus-storage rules at quote time (the program has been evolving) and document the configuration. For most single-family LA homes this is not a question; for duplex / triplex / fourplex property owners adding both solar and battery, we walk through the metering implications carefully. | VNM plus battery on multifamily property requires careful LADWP interconnection coordination; we confirm current rules and document the configuration. | VNM plus battery just works; LADWP figures it out. |
| What is the best next step before signing an LA battery contract? | Schedule a site visit, confirm your LADWP service (and not SCE), decide on the backup-loads list and battery sizing, run the LADWP TOU bill-impact and outage-resilience models, and — if income-qualified — check LADWP's RSSE (AB 209-funded Residential Solar and Storage Equity, sgip@ladwp.com) eligibility honestly: as of December 31, 2025 RSSE is fully reserved and accepting only waitlist applications via attrition. Statewide SGIP General Market / Equity / Equity Resiliency budgets do not apply to LADWP customers and are themselves closed to new apps. Get a written quote with line-item pricing: battery hardware, inverter, gateway, installation labor, LADBS permits, structural attachment, monitoring setup. Compare two or three bids on the same scope and battery brand. We do not pressure you to sign on the first call. | Compare two or three bids on the same scope after a site visit and a written backup-loads list; check LADWP RSSE if income-qualified — it is waitlisted as of Dec 31, 2025. | Sign today; LADWP rebates run out tomorrow. |
| Will the LADBS permit fee, structural review, and rebate paperwork all show up itemized in the proposal? | Yes. The proposal itemizes: LADBS electrical permit fee (typically $200-$500 depending on system size after the June 9, 2026 GPMS surcharge increase from 7 to 10 percent), structural review if required (typically $500-$1,500), RSSE rebate paperwork submission as a labor line if eligible, LADWP interconnection application fee, and any monitoring setup labor. We do not bundle these into 'labor' as a lump sum. Bundling is how installers hide the actual rebate value pass-through. | We itemize LADBS permit fee, structural review, RSSE submission if eligible, LADWP interconnection fee, and monitoring setup in the proposal. | Permits are bundled; do not worry about the breakdown. |
| Will you perform an NEC Article 220 load calculation before sizing the new panel or service? | Yes. We total existing connected loads, apply Article 220 demand factors, then add expected future loads (heat pump HVAC, heat pump water heater, EV charger, induction range, battery) before recommending a service size. | We perform the Article 220 calculation during the site visit and share the worksheet with the quote. | We size from the existing panel rating. |
| Is this a service upgrade or a panel-only replacement, and how do you decide? | We explain the difference plainly: a service upgrade changes the service drop, meter, and main breaker rating (utility coordination required); a panel-only replacement swaps the breaker box at the existing service rating. We base the recommendation on the Article 220 result, not on a default upsell. | We confirm after the load calc whether the existing service amperage is adequate; if it is, we propose a panel-only replacement. | It is the same thing. |
| Who coordinates with the utility for the service upgrade, and what lead time should we expect? | We coordinate with the serving utility (your investor-owned utility such as PG&E, SCE, or SDG&E, or your municipal utility such as LADWP or SMUD) for the service drop, meter swap, and any utility-side work. We document the expected utility lead time in the quote because it often dominates the project schedule. | We open the utility ticket after permit issuance and update the schedule when the utility confirms its lead time. | The utility handles itself. |
| How do you decide between 200A, 225A, or 320A service, and how much headroom should we plan for? | We size to the Article 220 calculated demand plus headroom for the ten-year horizon of electrification projects already on the table. For most California single-family homes adding heat pump HVAC, heat pump water heater, and one or two EVs, a properly sized 200A service is enough; 225A or 320A is only justified when the load calc shows it. | We present two options with the load-calc deltas so the homeowner can decide between 200A and 225A. | Bigger is always better, so we go 320A. |
| When does a smart panel (Span, Lumin, Eaton EV Choice) make sense versus a standard load center? | A smart panel can avoid a service upgrade when load shedding can keep peak demand under the existing service rating, or when granular per-circuit metering is desired. A standard load center is the right choice when the Article 220 result already fits the service rating, the homeowner does not want app-based controls, or budget is tight. | We model both options against the load calc and present the cost delta plus tradeoffs. | Smart panels are always the answer. |
| Is a sub-panel addition (for a detached garage, ADU, or workshop) a viable alternative to a full service upgrade? | A sub-panel can serve outbuilding loads without changing the main service rating when the Article 220 calc shows the existing service still has capacity. We size the sub-panel feeder per NEC and run it under permit. | We compare a sub-panel addition against a service upgrade with the load-calc results, then recommend the option that fits the future plan. | Sub-panels always require a service upgrade. |
| Will you inspect and update the grounding electrode system as part of the panel work? | Yes. We verify the grounding electrode system (ground rods, water-pipe bond, concrete-encased electrode where present), measure resistance where required, and upgrade conductors and connections to the current code edition adopted by your jurisdiction. | We inspect the grounding electrode system during the rough-in and bring it to current code if any element is deficient. | Grounding is fine if the panel is bonded. |
| Which circuits in the new panel will require AFCI or GFCI protection, and what code edition are you applying? | We apply the California Electrical Code edition currently adopted by your local AHJ (the California Electrical Code is based on the NEC with California amendments). We itemize AFCI-required and GFCI-required circuits and price the AFCI/GFCI breakers separately so the homeowner sees the cost driver. | We apply AFCI and GFCI rules per the current adopted code edition and confirm exact requirements during permit submittal. | AFCI rules are confusing, so we skip them. |
| Will the quote include whole-home surge protection, and which type? | We recommend a Type 2 surge protective device (SPD) integrated with the new panel as a standard line item; Type 1 SPD at the service entrance is an upgrade option for homes with frequent utility-side transients. We explain warranty terms and replacement procedure after a major surge event. | We include a Type 2 SPD with the panel and price a Type 1 SPD upgrade separately. | Surge protection is unnecessary. |
| Does the existing panel location meet current code clearances, or do we need to relocate it? | We measure NEC Article 110 working-clearance requirements (depth in front of the panel, clear width, headroom) and confirm the panel is not behind cabinets, in clothes closets, or in other prohibited locations. If the location does not meet current code, we quote the relocation. | We verify clearance during the site visit and quote relocation only if the current spot does not meet code. | The existing spot is fine because the old panel fit. |
| Will you use conduit or NM cable for the new circuits, and how do you decide? | We follow the California Electrical Code wiring methods permitted for residential occupancies. Conduit is required for exterior runs and where physical damage is likely; NM cable is permitted in many concealed interior runs. We size conductors for the future load, not just today's circuit. | We follow code wiring methods and explain any conduit upgrades that affect the price. | Whatever is easiest and cheapest. |
| Who pulls the electrical permit at the local AHJ (city or county permit center), and is the fee itemized in your quote? | We pull the electrical permit at the local AHJ in our own name, attend the inspection, and itemize the permit fee in the quote. We do not ask the homeowner to pull the permit. | We pull the permit at the local AHJ and break out the fee on the quote. | We do not pull permits because they slow the job. |
| Walk us through the inspection process: which inspections are required and what does each one check? | We typically schedule a rough-in inspection (panel mounted, grounding electrode system verified, conductors run) and a final inspection (devices terminated, AFCI/GFCI verified under test, labeling complete). The exact sequence depends on the local AHJ. | We confirm the inspection sequence with the AHJ at permit submittal and update the homeowner on the schedule. | There is just one inspection at the end. |
| How long will the home be without power during the panel swap, and what time of day will it occur? | A panel-only swap typically takes 6 to 10 hours; a service upgrade with meter swap can take a full day and is constrained by the utility's window. We confirm the exact window and time-of-day with the utility before scheduling. | We give a window once the utility confirms the meter swap appointment. | Will not take long. |
| Will the new panel be sized and labeled for future solar or battery interconnection per NEC Article 705.12? | Yes. We size the busbar and main breaker so the future solar PV and battery interconnection meets NEC Article 705.12 (the 120% rule or supply-side connection, depending on the configuration). We document the headroom available so the future installer can verify quickly. | We confirm Article 705.12 compatibility during design and note the calculated headroom on the panel schedule. | Solar and battery do not affect panel sizing. |
| If we may add a generator interlock or transfer switch later, what should the new panel design account for? | We can include a generator interlock kit with the panel install, or pre-wire space for a future automatic transfer switch. Interlock is the lowest-cost option for occasional backup; ATS is the right path for whole-home automatic backup. | We pre-wire space for a future interlock or transfer switch if requested, and note it on the panel schedule. | Generator readiness is a future problem. |
| How are you treating the federal §25C tax credit for panel-upgrade work? | The federal §25C Energy Efficient Home Improvement Credit expired December 31, 2025 under OBBBA (PL 119-21). For panel work performed in 2026 and later, we do not list §25C as an applicable credit and we will not claim eligibility. | We confirm the current federal-credit status against the IRS guidance at quote time and update the homeowner. | You qualify for the 30 percent federal tax credit on panel work. |
| Is panel-upgrade work eligible for HEEHRA (Home Electrification and Appliance Rebates) in California, and what is the current funding status? | Panel-upgrade work, sub-panel additions, and electrical wiring needed to support qualifying electrification projects can be eligible HEEHRA expenses for income-qualified households. CPUC reported HEEHRA funds fully reserved earlier this year, so we do not promise current availability and confirm against the CPUC HEEHRA portal at quote time. | We share the current HEEHRA funding status from the CPUC portal and adjust the incentive line items accordingly. | HEEHRA covers all panel upgrades automatically. |
| Are there TECH Clean California, CCA (Community Choice Aggregator), or utility-side incentives that apply to this panel work? | TECH Clean California is statewide for qualifying heat-pump installations; panel-upgrade work tied to a qualifying heat pump may be eligible. Many CCAs (such as MCE, SVCE, CleanPowerSF, SJCE) and IOUs run their own electrification rebates with panel-work eligibility. We confirm the program rules in writing before the quote and list each program with its reservation status. | We confirm current eligibility with each named program and document the reservation status on the quote. | All rebates are guaranteed if you sign today. |
| What is the manufacturer warranty on the new panel, breakers, and any smart-panel hardware? | We list the manufacturer warranty for the panel and main breaker (typically 10 years), branch-circuit breakers (typically 1 to 10 years), and smart-panel hardware separately. We explain what voids each. | We attach the manufacturer warranty documents with the quote. | Warranty is whatever the box says. |
| What is your labor warranty on the panel installation, and does it cover related troubleshooting? | We offer a written labor warranty (typically 1 to 5 years) covering workmanship on terminations, conduit runs, and grounding work. We explain what is covered and what is not. | We include a written labor warranty with the quote and explain the covered scope. | Our work is good, no warranty needed. |
| Based on the Article 220 result, what do you recommend as the best next action and why? | We propose a single recommended option with the load-calc rationale, list one alternative with the cost delta, and explain what would change our recommendation. We are clear about which costs are firm and which depend on the utility or AHJ. | We summarize the recommendation in writing after the site visit and load calc. | Whatever you want is fine. |

- TECH (closed November 14 2025) and HEEHRA (waitlisted as of February 24 2026) listed at current reservation status, not as confirmed savings
Reasonable caveats
- Phased work means multiple LADBS permit cycles
- Site visit cost may not credit toward later phases
- Rebate stacking timing matters (LADWP CRP reservation order; RSSE waitlist; HEEHRA waitlist)
- Older Spanish, Craftsman, and bungalow stock may need rewiring, structural review, or panel upgrade scope that surfaces during site visit
- Per-phase pricing may shift after site visit
- LADWP and LADBS coordination on dedicated EV meter and PTO has historically run 4-12 weeks; we share current estimates
Red flags
- Quotes whole-home lump-sum with no per-phase pricing
- Recommends solar or battery before panel-capacity verification
- Skips Manual J for HVAC sizing
- Promises stacking without confirmed reservations
- Lists §25C or §25D federal credits as applicable for 2026+ work
- Pitches statewide SGIP General / Equity / Equity Resiliency tiers on LADWP service (those do not apply; RSSE is the LADWP path)
- Treats LADWP and SCE service areas as interchangeable

| California Net Billing Tariff (NEM 3.0) — solar export compensation framework | Policy framework, not a direct rebate. Excess solar generation exported to the grid is compensated at a rate reflecting the time-varying grid value of that generation (Avoided Cost Calculator methodology), rather than at the retail electricity rate that NEM 2.0 used. Net export compensation under the Net Billing Tariff is typically materially lower than under NEM 2.0; pairing solar with battery storage may materially affect project economics under this framework. | POLICY IN EFFECT — NOT A REBATE: The Net Billing Tariff (NBT), commonly called 'NEM 3.0,' is the current Net Energy Metering framework for new residential solar interconnections in California, adopted by CPUC Decision 22-12-056 and effective for applications submitted on or after 2023-04-15. It applies to new customer-generator interconnections in the three large investor-owned utility territories: Pacific Gas and Electric (PG&E), Southern California Edison (SCE), and San Diego Gas & Electric (SDG&E). LADWP and other publicly owned utilities operate their own net-metering tariffs and are not covered by NBT. Under NBT, onsite solar generation first offsets the customer's own consumption; excess generation exported to the grid is compensated at a time-varying export rate based on the grid's avoided cost rather than the retail rate. Existing NEM 1.0 / NEM 2.0 customers are generally grandfathered under the legacy tariff for a defined period from their original interconnection date — verify against the customer's utility for the legacy term. Homeowners considering new residential solar in PG&E / SCE / SDG&E territory should model project economics specifically under NBT, with and without paired battery storage, before signing a contract. | Interconnection application required, not a financial preapproval. | high | 2026-05-30 | California Public Utilities Commission (CPUC) |
| California Equitable Building Decarbonization (EBD) Direct Install Program | No-cost direct-install upgrades for income-qualified households — homeowner does not pay out-of-pocket for covered measures. Measures may include heat pump HVAC, heat pump water heater, induction stove, electrical panel upgrade, and weatherization, subject to a per-household scope set by the regional implementer. | Administered by the California Energy Commission (CEC) as the statewide Equitable Building Decarbonization Direct Install Program, with delivery through regional implementers and a separate Tribal Direct Install track. Targets low- and moderate-income households in low-income communities; specific AMI thresholds and per-region eligibility rules are set by the regional implementer rather than statewide. Both single-family homeowners and renters in eligible buildings may qualify, though scope and contractor selection are determined by the implementer (homeowners do not freely choose contractors). The program is funded through California IRA HOMES funding (60% allocation to Direct Install, approximately $130.3M) plus state appropriations. Direct Install retrofits began rolling out in summer 2025. Homeowners interested in EBD should contact the CEC at equitablebuildingdecarb@energy.ca.gov or watch for their regional implementer's launch announcement; the program does not accept open online applications the way TECH or HEEHRA do. | Yes | medium | 2026-05-30 | California Energy Commission (CEC), California Energy Commission (CEC) |
| Section 30C Alternative Fuel Vehicle Refueling Property Credit (residential EV charger) | Had a statutory cliff on June 30, 2026. For property placed in service Jan 1, 2023 – June 30, 2026: 30% of the cost of qualifying residential EV charging property, up to $1,000 per item (per charging port, fuel dispenser, or storage property), claimed on IRS Form 8911. Only homes located in a qualifying low-income community or non-urban census tract may have qualified. Installations placed in service after June 30, 2026 do not qualify. | §30C federal EV-charger credit had a statutory cliff on June 30, 2026 (OBBBA Public Law 119-21, 139 Stat. 72, signed July 4, 2025). Under the statute, the credit 'will not be allowed for any property placed in service after June 30, 2026.' This was a cliff termination with no transition rate — installations placed in service on July 1, 2026 or later do not qualify, regardless of when payment or contracting occurred. For property placed in service Jan 1, 2023 through June 30, 2026, the credit covered 30% of the cost of qualifying alternative fuel vehicle refueling property installed at a U.S. home used by the taxpayer as a main home, capped at $1,000 per item (the cap applied separately to each charging port, fuel dispenser, or storage property). Property had to have original use beginning with the taxpayer. Census-tract eligibility was the load-bearing constraint: per IRS guidance, the property had to be installed in a low-income community census tract or non-urban census tract — 2015 Census Tract boundaries applied to installations placed in service before Jan 1, 2025; 2020 Census Tract boundaries applied to installations placed in service on or after Jan 1, 2025. Many urban high-income census tracts did not qualify even where the homeowner installed an otherwise eligible charger. Homeowners claimed the credit on Form 8911 attached to their federal tax return. Pre-cliff installs may have qualified — verify both the placed-in-service date and the census-tract eligibility of the install address with a qualified tax preparer before relying on this credit. | Verify | high | 2026-06-08 | Internal Revenue Service, Internal Revenue Service |
| SCE Charge Ready Home — residential panel upgrade rebate for EV charging | Income-qualified tier: up to $4,200 (covers 100% of panel upgrade cost). Geographic tier (SB-535 disadvantaged community): up to $2,100 (covers 50% of panel upgrade cost). No general-market tier — homeowners outside both eligibility tiers do not qualify. | As of 2026-05-30 the program is active. Applicants must be active SCE residential electric customers. The income-qualified tier may be available to households at or below 80% of county Area Median Income, or to participants in CalFresh, Medi-Cal, SSI, WIC, or similar assistance programs. The geographic tier may be available to homes located in a top-25% disadvantaged community per the CalEnviroScreen / SB-535 map. The program rebates the panel upgrade itself; an L2 (Level 2) EV charger must be installed within 180 days of panel-upgrade completion to receive the rebate. Applications can be submitted before, during, or up to six months after panel-upgrade completion. The program is structured differently from PG&E's Residential EV Charging Rebate — SCE Charge Ready Home rebates the panel; PG&E's program rebates the charger (with Rebate Plus tier bundling panel+charger). Homeowners should verify current rebate amounts and eligibility against the program page before signing a contract. | Application can be submitted before, during, or up to 6 months after panel upgrade completion; an L2 EV charger must be installed within 180 days of panel-upgrade completion. | high | 2026-05-30 | Southern California Edison, Southern California Edison |
| SCE Energy Savings Assistance Program (ESA) — income-qualified no-cost upgrades | No-cost (program-funded) upgrades for eligible households.

| SCE Heat Pump HVAC Rebate — current status | Not currently available as a standalone universal SCE rebate. Geographic-eligible homeowners may qualify through HPP; income-qualified homeowners may qualify through ESA — see those records for amounts. | As of 2026-05-30 SCE does not advertise a standalone universal residential heat-pump HVAC rebate on its rebates index. Heat-pump HVAC incentives for SCE-served homes flow through four channels: (a) SCE Home Performance Plus (sce-home-performance-plus) — geographic-eligible households in SB-535 disadvantaged communities; (b) SCE Energy Savings Assistance Program (sce-energy-savings-assistance) — income-qualified households; (c) TECH Clean California (single-family fully reserved since November 14, 2025; see ca-tech-heat-pump-hvac); (d) HEEHRA-CA (single-family fully reserved since February 24, 2026; see ca-heehra-single-family). Homeowners who don't qualify for HPP or ESA must wait for TECH or HEEHRA to reopen, or use third-party regional programs. Homeowners may want to verify with SCE and check whether any successor universal-tier program has launched. | Verify | high | 2026-05-30 | Southern California Edison, Southern California Edison |

| LADWP Solar — Net Metering (No Upfront Rebate) | As of 2026-05-30, LADWP does NOT offer a residential upfront solar PV rebate; its legacy Solar Incentive Program for residential customers has been closed. The compensation mechanism for LADWP residential solar is net metering: excess generation exported to the grid is credited at the customer's applicable retail rate (R-1A tier price or R-1B TOU price). System size cap is 1 MW. Important: LADWP customers are NOT subject to CPUC's NEM 3.0 / Net Billing Tariff (NBT) — that framework applies only to PG&E, SCE, and SDG&E customers. Homeowners should verify current LADWP NEM terms before signing a contract, as municipal tariffs can change at LADWP Board action. | LADWP residential electric customer with an active meter. System must meet LADWP interconnection requirements (sizing relative to historical load, equipment on approved list, LA Department of Building and Safety permitting and inspection). For solar paired with battery, separate interconnection rules apply. | Interconnection application required, not a financial preapproval. | medium | 2026-05-30 | Los Angeles Department of Water and Power |
| LADWP Electrical Panel Upgrade — No Direct Rebate | As of 2026-05-30, LADWP does not offer a standalone residential rebate for electrical service panel upgrades. The federal Section 25C credit (historically covered up to $600 for panel upgrades tied to qualifying electrification work) has expired — see federal-25c-electrical-panel for the sunset details. LADWP customers should not assume the CPUC-IOU TECH Clean California or HEEHRA-CA panel-upgrade adders apply to them; those programs are administered for IOU customers and LADWP customers are typically not eligible. Homeowners may still need to budget the full panel-upgrade cost when scoping electrification work. | Not applicable — no LADWP-administered residential panel-upgrade rebate identified as of 2026-05-30. Homeowners should ask their contractor about any active stackable programs and verify with LADWP directly before relying on an incentive. | Verify | medium | 2026-05-30 | Los Angeles Department of Water and Power |
| LADWP Customers and CPUC-IOU Programs — Eligibility Disclosure | As of 2026-05-30, LADWP residential customers are generally NOT eligible for the following CPUC-administered or IOU-funded California incentive programs, which are restricted to investor-owned utility (PG&E, SCE, SDG&E) customers: TECH Clean California (heat pump incentives — fully reserved as of Pass 2 in any case), HEEHRA-CA (single-family heat pump rebates — fully reserved single-family as of Pass 2), the Self-Generation Incentive Program (SGIP — battery storage), Golden State Rebates (IOU joint program), and the CPUC NEM 3.0 / Net Billing Tariff for new solar interconnections. LADWP runs its own parallel rebate portfolio (Consumer Rebate Program for HVAC / water heating / cool roofs, Charge Up LA! for EV chargers, and its own net-metering tariff). Homeowners served by LADWP should look to the LADWP CRP rather than CPUC-IOU programs when scoping incentives. | Applies to all LADWP-served residential addresses. Homeowners who are unsure whether they are served by LADWP or SCE should check the utility name printed on their most recent electric bill — the eligible program set differs materially between the two utilities even within LA County. | Verify | high | 2026-05-30 | Los Angeles Department of Water and Power |
