25C — Energy Efficient Home Improvement Credit →
Annual cap is $1,200 most categories, $2,000 for heat pumps / HPWH / biomass. Resets each tax year — strategic to split projects across calendar years.
Equipment category · 6 eligible programs
Heat pump rebates for PNW homeowners.
Air-source or ductless heat pump installation — the highest-rebate-eligibility category in the Pacific Northwest by a wide margin.
Why it matters
The case for heat pump rebates
Heat pumps are the centerpiece of WA's residential electrification push. They replace furnaces (gas → electric) and AC units (efficient cooling + heating in one unit) at typical PNW outdoor temperatures. Federal + state + utility programs all stack favorably here.
Typical install scope
What "heat pump" usually involves
Outdoor compressor unit + indoor air-handler / cassette / ducted distribution. Adds dedicated 240V circuit. Often paired with electrical panel upgrade for older homes still on 100A service.
Pacific Northwest context
What's different about PNW installs
PNW climate is ideal for air-source heat pumps — winters rarely drop below the equipment's effective temperature range. Cold-climate variants (CCH-rated) are recommended for higher-elevation or east-of-Cascades installs but unnecessary for most Puget Sound homes.
Install notes
What to confirm with your installer
Look for HSPF2 ≥ 7.5 and SEER2 ≥ 15.2 to qualify for federal 25C tier. Utility rebate tiers go higher. Get the AHRI certificate from your installer — it's the eligibility document for every rebate program.

HEEHRA — Home Electrification & Appliance Rebate →
Each state administers HEEHRA differently. WA's implementation launched 2025; check status before assuming current availability — funding can run out per program-year.
Utility
PSE Energy Efficiency Incentives →
PSE separates electric and gas incentives. If converting from gas to heat pump, you may unlock both gas-side (decommission) and electric-side (install) rebates. Check the contractor finder for PSE Trade Allies.

Tacoma Power Rebates →
Some Tacoma Power rebates have income tiers — moderate-income homeowners get higher rebate amounts. Cross-check with HEEHRA stacking eligibility.

SnoPUD Energy Programs →
SnoPUD's PowerHaul Heat Pump program has specific equipment-tier requirements (HSPF / SEER thresholds). Match your spec sheet to the program tier before purchase.

Seattle City Light Rebates →
Seattle's Building Performance Standards and electrification mandates can stack with SCL rebates for some property types. Check both program tracks before scoping.
