Why Washington runs above the US average
Heat pump pricing in Washington reflects three factors: licensed HVAC installer wages (BLS), local utility rebate programs that often pay $500-$1,500 on top of the federal credit, and climate-driven equipment selection (cold-climate units are 10-20% more expensive than baseline air-source). The 1.18× factor is calibrated from 2025 HomeAdvisor + ENERGY STAR install cost data.
Local note · Washington: Puget Sound Energy + Avista rebates $400-$2,500; PNW climate well-suited to ductless mini-split.
