Insulation rebates for PNW homeowners.
Attic, wall, and crawlspace insulation upgrades to current PNW residential code standards (R-49 attic, R-21 walls minimum).
Why it matters
The case for insulation rebates
Insulation is the foundation of any electrification project — heat pumps and HPWH efficiency depend on the building envelope. PNW utility rebates often require insulation as a prerequisite for heat-pump rebates.
Typical install scope
What "insulation" usually involves
Attic blown-in cellulose or fiberglass to R-49; wall fill (blown-in or batt) to R-21; crawlspace under-floor batts; rim joist sealing. Air-sealing pass (caulk + foam at penetrations) usually included.
Pacific Northwest context
What's different about PNW installs
Most PNW homes built before 1990 are under-insulated by current code. Cellulose blown-in is common for attic retrofits — denser, more pest-resistant, and works around obstructions easier than batt. Air-sealing is often more impactful than added R-value alone in older homes.
Install notes
What to confirm with your installer
Get a pre-install blower-door test if your utility requires it — measures air leakage and tells you whether sealing or insulation gives bigger ROI. Some programs require post-install verification by a certified energy auditor.

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.

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.
