Heat Pump Rebates in Seattle, Washington (2026)

Seattle's mild marine climate is well-suited for air-source heat pumps without specialized cold-climate equipment. Seattle City Light (the municipal electric utility) and Puget Sound Energy (gas + suburban electric) offer heat pump rebates ranging $300–$1,500. Washington state has a 100% sales tax exemption on heat pump equipment (saving ~10% on $14,000 install = ~$1,400). Combined with federal 25C (30% up to $2,000) and HEEHRA for income-qualified, Seattle heat pump installs deliver strong economics despite the absence of a single dominant program like Massachusetts Mass Save. Seattle's heating-dominated climate (winter heating ~85% of energy use, cooling ~5%) makes heat pumps particularly impactful for total energy bill reduction.
