Washington Heat Pump Rebates
Stackable incentives available to Washington homeowners installing a qualifying heat pump in 2026.
Rebate data is re-verified against primary sources every two months.
What's available in Washington
Washington's heat pump help comes from utilities: PSE ($1,500, $2,400 income-qualified), Snohomish PUD (up to $2,500), Tacoma Power (up to $2,000), Seattle City Light and Avista ($300-$600 instant discounts), plus Seattle's $2,000 oil-to-heat-pump rebate. The state's IRA HEAR/HOMES rebates are still awaiting DOE launch approval as of mid-2026. Mild climate means standard heat pumps perform well year-round.
HEEHRA in Washington
HEEHRA rebate: Point-of-sale rebate up to $8,000 for households at or below 80% of area median income. Funded by the IRA, administered by each state. Washington HEEHRA is closed as of 2026-09-07 — funding fully exhausted.
How heat pump rebates work in Washington
Washington has strong utility programs, especially in the PSE and Seattle City Light territories, but the state's mild climate means standard heat pumps perform well year-round and the rebate amounts reflect that — fewer 'cold-climate' bonus tiers than New England or the upper Midwest. Puget Sound Energy (PSE) pays single-family residential electric customers $1,500 for replacing electric resistance heat with a qualifying air-source heat pump (ducted or ductless). Income-qualified Energy Boost adds up to $2,400 more for households below the program threshold. Seattle City Light offers a tiered $300 to $600 instant contractor discount on qualifying heat pumps (the top tier requires HSPF2 9.5 and SEER2 16), applied through participating distributors. The City of Seattle Clean Heat program adds a $2,000 instant rebate for converting from oil heat to a heat pump using a participating contractor, with a $4,000 bonus for households at 81-150% of AMI on installs completed by May 30, 2027, and a free heat pump for households at or below 80% AMI. The three programs are mutually exclusive by utility + existing-fuel combination — PSE territory + electric resistance, Seattle + electric resistance, Seattle + oil. WA HEEHRA through the Washington State Department of Commerce has not launched yet: as of mid-2026 Commerce and administrator Guidehouse are awaiting DOE approval, and rebates will not be retroactive. When it opens, households at or below 80% AMI are expected to qualify for up to $8,000 toward a heat pump.
Washington rebate programs
PSE Heat Pump Rebate
$1,500PSE single-family residential electric customers replacing electric resistance heat (electric furnace, baseboard, wall or radiant heat) with a qualifying air-source heat pump, ducted or ductless, get $1,500; homes that already have a heat pump serving the main living area are not eligible. Income-qualified customers get a $2,400 Efficiency Boost rebate instead of the standard amount (PSE publishes a per-county income table), and income-qualified natural gas conversions can get up to $4,000. Must use a PSE Recommended Energy Professional or Trade Ally contractor; one rebate per home.
Seattle City Light Heat Pump Rebate
$600Seattle City Light runs a tiered instant contractor discount on air-source and ductless heat pumps under 5.4 tons: $300 at HSPF2 8.1+, $400 at HSPF2 8.5+ (both SEER2 15.2), and $600 at HSPF2 9.5+ with SEER2 16. The discount comes off the contractor's invoice through participating distributors; DIY installs do not qualify. A separate $750 heat pump water heater rebate is also available.
Seattle Clean Heat Oil-to-Heat-Pump Rebate
$2,000City of Seattle (Office of Sustainability & Environment) $2,000 instant rebate for converting from oil heat to a qualifying Mitsubishi Electric heat pump through a participating contractor. Households at 81-150% of area median income get a $4,000 bonus on top (up to $6,000 total) for installs completed by May 30, 2027; households at or below 80% AMI can get a free heat pump with installation and oil tank decommissioning through the Office of Housing instead.
WA HEEHRA (income-qualified)
$8,000NOT currently claimable. As of Commerce's June 15, 2026 update, Washington's IRA HOMES and Home Appliance Rebate Program (HARP) are in final operations setup with administrator Guidehouse and awaiting DOE approval to launch; no applications are being taken and rebates are not retroactive, so work done before approval will not qualify. Households up to 150% AMI are expected to be eligible when it opens, with up to $8,000 toward a heat pump at or below 80% AMI. Treat the $8,000 as future-state.
Tacoma Power Heat Pump Rebate
$2,000Tacoma Power customers replacing zonal electric or electric forced-air heat get $1,000 for a ducted air-source heat pump or a ductless system (up to 4 indoor units; $650 for 5+ units), and $2,000 for a variable-speed heat pump replacing an electric forced-air furnace. Homes converting from non-electric heat qualify only for $1,000 on a variable-speed system. Must use a Tacoma Power Participating Contractor; electric-heat homes can also get a 0% 7-year loan up to $20,000, and income-qualified households can get a deferred loan with no payments until the home is sold.
Snohomish PUD Ducted Heat Pump Rebate
$2,500Snohomish County PUD electric customers whose primary heat is electric get $1,800 for a ducted heat pump conversion (min 7.5 HSPF2 / 13.8 SEER2) or $2,500 for an inverter-driven ducted heat pump (min 8.5 HSPF2). Applies to owner-occupied single-family, manufactured homes, townhomes and condos in buildings of up to four units. Work must be done by a PUD registered contractor, who takes the rebate off the invoice and files the paperwork; the PUD inspects before paying.
Avista WA Heat Pump Instant Discount
$600Avista Washington electric customers get a midstream instant discount on air-source or mini-split heat pumps under 5.4 tons: $300 (SEER2 15.2 / HSPF2 8.1), $400 (HSPF2 8.5) or $600 (SEER2 16 / HSPF2 9.5). The discount is applied by the contractor through participating distributors, with no customer application; DIY installs are not eligible.

A worked example: oil-to-heat-pump conversion in Seattle
Yelena owns a 1,650 sq ft home in central Seattle, currently heated by a 32-year-old oil-fired furnace. She's a Seattle City Light electric customer. She gets quotes for a 2.5-ton ducted air-source heat pump installed by a Seattle Clean Heat participating contractor at $14,600. Because the install converts from oil heat to a heat pump, she qualifies for the Seattle Clean Heat Oil-to-Heat-Pump Rebate at $2,000 (instant rebate processed through the participating contractor). Seattle City Light's $300-$600 instant heat pump discount is a separate midstream program; her contractor should check whether the distributor discount can be applied alongside Clean Heat — Clean Heat is the right path. Her household income is approximately 88% of King County AMI — above the 80% threshold for WA HEEHRA, so the federal $8,000 doesn't apply. The federal §25C credit is gone. Combined stack: $2,000 against $14,600. Net out-of-pocket: $12,600.
Choosing a contractor in Washington
Washington licenses HVAC contractors through the Department of Labor and Industries — verify Construction Contractor Registration at lni.wa.gov before signing. PSE rebates require a PSE Recommended Energy Professional contractor; the REP list is on pse.com. Seattle Clean Heat rebates require a participating contractor enrolled with the Seattle Office of Sustainability and Environment; the participating contractor list is on seattle.gov/environment. Seattle City Light rebates require an SCL-approved contractor. The three programs maintain separate contractor rosters — confirm enrollment per program.
Common pitfalls for Washington homeowners
- Stacking PSE, Seattle City Light, and Seattle Clean Heat. The three programs are mutually exclusive by utility + existing-fuel combination. A homeowner is in PSE OR Seattle City Light territory, and has electric resistance OR oil as the existing fuel. A single install matches one combination. Aggregator sites that sum 'PSE $1,500 + SCL $600 + Clean Heat $2,000 = $4,100' are misleading because no household is in both PSE and Seattle City Light territory.
- Missing the Seattle Clean Heat 2026 deadline. Seattle Clean Heat's $4,000 moderate-income bonus applies only to installs completed by May 30, 2027; the base $2,000 rebate has no published end date but depends on remaining funding. Schedule oil-conversion installs to complete with margin before the deadline.

How to claim each rebate
- Get pre-approved (where required). Some utility programs require approval before install. Check program details before signing a contract.
- Use a participating contractor. Many programs require a licensed installer from an approved contractor list — especially HEEHRA, which routes through CEC-approved contractors who process the rebate at point of sale.
- Save documentation. AHRI certificate, model numbers, and itemized invoice are required for most utility rebates.
- Submit utility rebate within 60–90 days of install. Some programs are first-come first-served and close mid-year — funding can run out before the calendar year does.
If you can't afford a replacement in Washington
Rebates lower the price, but they still assume you can pay the rest. If your heating system is unsafe or has failed and a new one is out of reach, these programs repair or replace equipment at low or no cost for income-qualified households. Heat Pump Pricing Index is an independent information site — we don't fund, discount, or install equipment — so these are the doors to knock on first:
- Weatherization Assistance Program (WAP). Free energy and health-and-safety repairs — an unsafe furnace is exactly the kind of problem it fixes — for households at or near 200% of the poverty line. Apply through your local community action agency: how to apply (energy.gov).
- LIHEAP. Heating-bill help plus, in most states, a crisis component for broken or dangerous heating equipment. Same local agency; Washington LIHEAP contacts.
- USDA Section 504 Home Repair. For homeowners outside cities: 1% loans up to $40,000, and grants up to $10,000 for homeowners 62 and older to remove health and safety hazards. Program page and state offices (rd.usda.gov).
- Your utility and 211. Most electric and gas utilities run an income-qualified assistance fund — call the number on your bill and ask. Dialing 211 reaches a local specialist who knows which agencies in Washington currently have funds.
Safety first: if a technician has told you a heat exchanger is cracked, stop using the furnace and make sure you have a working carbon monoxide detector before anything else.
