Washington has moved faster on building electrification than almost any other state in the country. The combination of an active state HEEHRA rollout, the Clean Buildings Performance Standard, HB 1589's gas-line obligation reform, and utility programs like PSE's HELP and Tacoma Power's rebates means a single heat pump installation in Seattle, Tacoma, or Spokane can pull from four or five funding sources at once.
That stack matters. A cold-climate ducted heat pump that lists at $18,000 to $24,000 installed in the Puget Sound region can often land in the $6,000 to $10,000 range for a low-income household — but only if the application order is right and the programs are layered correctly.
How much can Washington households get from HEEHRA for a heat pump?
Washington's HEEHRA program offers up to $8,000 for a qualifying ENERGY STAR cold-climate heat pump for households at or below 80% of Area Median Income, and up to $4,000 for households between 80% and 150% AMI. Rebates cover up to 100% of project costs for low-income tiers and 50% for moderate-income tiers, administered through the Washington State Department of Commerce.
What Is HEEHRA, And Why Does Washington's Version Look Different?
HEEHRA — the High-Efficiency Electric Home Rebate Act — is the federal IRA-funded rebate program administered state-by-state. Washington's allocation, roughly $156 million per Department of Energy estimates, flows through the Washington State Department of Commerce rather than utilities directly.
That structure matters because it allows HEEHRA dollars to layer on top of existing utility rebates rather than replacing them. Keep in mind that Washington was among the first wave of states to launch its HEEHRA portal, with full statewide rollout phased through 2026.

HEEHRA Washington: Rebate Amounts By Equipment And Income Tier
The Washington Department of Commerce publishes equipment-specific rebate caps that mirror the federal HEEHRA structure with state-level administrative adjustments. The headline numbers below reflect program guidance as of the most recent Commerce publication — verify your exact award letter before signing a contract.
| Equipment | ≤80% AMI (100% covered, up to) | 80–150% AMI (50% covered, up to) |
|---|---|---|
| Heat pump (HVAC) | $8,000 | $4,000 |
| Heat pump water heater | $1,750 | $875 |
| Electric/induction stove | $840 | $420 |
| Heat pump clothes dryer | $840 | $420 |
| Electrical panel upgrade | $4,000 | $2,000 |
| Wiring | $2,500 | $1,250 |
| Insulation, air sealing, ventilation | $1,600 | $800 |
| Project cap (whole home) | $14,000 | $14,000 |
The $14,000 whole-home cap is the binding ceiling for any single household. That means a household replacing a gas furnace, a gas water heater, and adding panel capacity all in one project can stack equipment rebates up to that aggregate limit.
What are Washington's HEEHRA income limits?
Washington uses Area Median Income (AMI) by county, not statewide. In King County for a family of four, 80% AMI is approximately $116,000 and 150% AMI is roughly $217,000. Spokane County thresholds run substantially lower — about $74,000 and $139,000 respectively. Use the Washington Department of Commerce HEEHRA portal to confirm your county-specific threshold.
How The Washington Clean Buildings Act Changes The Calculus
The Washington State Clean Buildings Performance Standard, enacted under HB 1257 and expanded under HB 1390, sets enforceable energy use intensity (EUI) targets for commercial and multifamily buildings over 20,000 square feet. That is a commercial standard, but it ripples into residential decisions in two specific ways.
First, the building code adopted under the State Building Code Council's 2021 cycle effectively requires heat pumps as the primary heating system in most new residential construction. Second, the policy signal has accelerated contractor training, rebate funding, and supply chain depth — meaning installers in Seattle, Bellevue, and Tacoma now quote heat pump retrofits routinely rather than as an exception.
HB 1589 And The Gas-Line Obligation Reform
HB 1589, passed in 2024, fundamentally restructures Puget Sound Energy's obligation to serve new gas connections. The bill allows PSE to file an integrated system plan that prioritizes electrification investment over expanded gas infrastructure.
For Washington homeowners, this matters in a practical way. Replacing a failed gas furnace with another gas furnace is becoming progressively more expensive as utilities reduce gas-line subsidies — while heat pump rebates expand in parallel.
Does HB 1589 ban gas appliances in Washington?
No. HB 1589 does not ban natural gas in existing homes or prohibit gas appliance purchases. It modifies Puget Sound Energy's obligation-to-serve requirements and allows PSE to file integrated system plans that may reduce subsidies for new gas hookups. Existing gas customers retain service; the policy shifts the long-run economics, not legality.
Utility Rebates That Stack On Top Of HEEHRA
Washington's utility rebate landscape is fragmented by service territory, but the major programs are mature and well-funded. Puget Sound Energy, Seattle City Light, Tacoma Power, Snohomish PUD, and Avista all run heat pump incentives that can be claimed alongside HEEHRA.
The general rule: HEEHRA covers a percentage of total project cost net of other rebates, so utility rebates apply first, then HEEHRA fills the gap up to the income-tier cap. Our guide on rebate stacking application order walks through the sequence in detail.
| Utility | Heat Pump Rebate | HPWH Rebate | Notes |
|---|---|---|---|
| Puget Sound Energy | Up to $2,200 (ducted) / $800 (ductless) | $500 | HELP program for income-qualified adds up to $7,500 |
| Seattle City Light | Up to $2,000 | $800 | Income-qualified pathway via Powerful Neighborhoods |
| Tacoma Power | $1,200 ducted / $800 ductless | $500 | Stacks with HEEHRA |
| Snohomish PUD | Up to $1,500 | $300 | Income-qualified tier available |
| Avista (Eastern WA) | $1,200 | $500 | Cold-climate spec required east of Cascades |
Cold-Climate Sizing East Of The Cascades
Washington is two climate zones in one state. West of the Cascades runs marine — 99% design temperatures in Seattle hover around 25°F, which a standard variable-speed heat pump handles without backup.
East of the Cascades is a different conversation. Spokane's 99% design temperature sits closer to 4°F, and Pullman drops lower; that pushes equipment selection toward cold-climate-rated variable-capacity inverters with HSPF2 ≥ 8.5 and capacity retention specs verified at 5°F.
For sizing methodology, see our walkthrough on cold-climate heat pump sizing. Note that Washington HEEHRA equipment lists require ENERGY STAR Cold Climate certification for any unit installed east of the Cascade crest.
Can I stack HEEHRA with the federal 25C tax credit in Washington?
The federal 25C residential energy efficient property credit changed substantially mid-2025. Check our current breakdown at what happened to 25C in July 2025 before assuming stackability. Where 25C remains available, it applies to net cost after HEEHRA and utility rebates — meaning the tax credit base shrinks as rebates grow.
Application Order For Washington Homeowners
The sequence below reflects what Department of Commerce and the major utilities have signaled as the cleanest path. Mistakes here can forfeit thousands in stackable funding.
- Pre-qualify income tier. Submit AMI documentation to the Washington HEEHRA portal before scoping equipment. Award letters are tier-specific.
- Get a Manual J load calculation. Washington HEEHRA, like most state programs, requires properly sized equipment. Rule-of-thumb sizing fails QA review.
- Confirm contractor enrollment. Both your utility's trade ally network and the state HEEHRA contractor registry must list the installer.
- Apply utility rebate first. The utility's pre-approval becomes documentation for the HEEHRA application.
- Submit HEEHRA application. Net project cost (after utility rebate) determines the HEEHRA fill-in.
- File 25C separately if eligible, on the following year's federal return.
Whole-Home Electrification Math For A Seattle Single-Family Home
Consider a 1,800 sq ft Craftsman in Ballard with a gas furnace, gas water heater, and a 100-amp panel. The owner is a single earner at roughly 75% King County AMI.
A representative project: ducted cold-climate heat pump ($19,000), heat pump water heater ($5,500), 200-amp panel upgrade ($3,800), and circuit wiring ($1,400). Total project: $29,700.
Estimated stack for this household (≤80% AMI):
- PSE HELP heat pump rebate: ~$7,500
- PSE heat pump water heater rebate: $500
- HEEHRA heat pump: up to $8,000
- HEEHRA HPWH: up to $1,750
- HEEHRA panel: up to $4,000
- HEEHRA wiring: up to $1,400 (capped at project cap)
- Out-of-pocket estimate: ~$6,550 (varies by exact AMI verification and equipment list)

How Washington Compares To Other HEEHRA States
Washington's program is among the most generous in equipment coverage and contractor depth, but other states have launched ahead on specific equipment lines. Compare neighbors: HEEHRA Oregon launched earlier with a tighter income-qualification process, while HEEHRA Illinois and HEEHRA New York took different administrative paths.
For the running cross-state status board, see HEEHRA state-by-state status.
When does Washington's HEEHRA program end?
Washington's HEEHRA allocation is funded through the federal Inflation Reduction Act and is expected to remain available through 2031 or until the state's $156 million allocation is fully obligated — whichever comes first. High-demand counties may exhaust funds earlier; the Department of Commerce reserves the right to pause intake when allocations near depletion.
Common Pitfalls In Washington HEEHRA Applications
The most frequent rejection reasons cited by Commerce intake reviewers cluster around three issues. Documentation errors stall applications longer than equipment-spec mismatches in our review of public program data.
- Wrong AMI documentation. Self-attestation alone is not sufficient; tax returns, pay stubs, or benefits-program verification are required.
- Unenrolled contractor. Equipment installed by a contractor not on the state registry is ineligible — even if the contractor is fully licensed.
- Equipment off the qualified list. The HEEHRA equipment list is narrower than ENERGY STAR generally; verify the specific AHRI match number.
- Manual J skipped. Rule-of-thumb sizing fails QA. Load calc documentation is increasingly required pre-approval.
- Receipts dated before pre-approval. HEEHRA does not retroactively reimburse projects begun before award.
Frequently Asked Questions
Can renters access HEEHRA in Washington?
Yes, but the application flow runs through the property owner. Washington's HEEHRA framework allows landlord-initiated applications for multifamily and single-family rental properties, with tenant-protection provisions including rent-stabilization commitments for income-qualified properties. Renters interested in heat pump upgrades should approach their landlord with the program details rather than applying directly.
How does HEEHRA interact with Seattle City Light's Powerful Neighborhoods program?
Seattle City Light's Powerful Neighborhoods program targets income-qualified households with deeper incentives that often cover full project cost for qualifying retrofits. Where Powerful Neighborhoods is available, it generally applies first — HEEHRA then fills any remaining gap up to the federal per-equipment cap. Households in Seattle should contact City Light's residential energy team before initiating a HEEHRA application to confirm sequence.
Does Washington HEEHRA cover ductless mini-splits?
Yes. Ductless mini-split heat pumps are eligible under Washington HEEHRA provided they meet ENERGY STAR Cold Climate specifications for installations east of the Cascade crest. West of the Cascades, the standard ENERGY STAR heat pump tier qualifies. For sizing context, see our guide on mini-split vs central heat pump tradeoffs.
What is the Washington HEEHRA timeline for actually receiving rebate funds?
Washington's HEEHRA structure is point-of-sale where possible — meaning the rebate is applied as a discount on the contractor invoice rather than reimbursed after the fact. For equipment lines where point-of-sale is not yet operational, reimbursement typically processes within 60-90 days of project completion documentation. Phased rollout means timing varies by equipment category through 2026.
Can I install a dual-fuel system and still qualify for HEEHRA?
Generally, no. HEEHRA is structured to support full electrification, and dual-fuel hybrid configurations that retain a gas furnace as primary backup typically do not qualify for the heat pump rebate. Cold-climate variable-capacity heat pumps with electric strip backup do qualify. Check our analysis of defrost cycle sizing for backup-heat tradeoffs in marine and inland climates.
The Bottom Line For Washington Homeowners
Washington's electrification stack is among the strongest in the country, particularly for income-qualified households west of the Cascades where mild winters and dense utility programs combine. The HEEHRA program adds meaningful headroom on top of utility rebates that were already moving the needle.
That said, the stack only works if the application order is right and the equipment list match is exact. Verify your county AMI, confirm contractor enrollment, and pull a real Manual J before signing — those three steps eliminate most rejection paths.
