Seattle's mild, marine climate keeps winters wet rather than brutally cold and summers cool compared to most of the country, but warming summer heat waves have made central AC and ductless heat pumps increasingly essential rather than optional in a region that historically relied on heating alone.
Historically many Seattle homes got by without it, but hotter, smokier summers have made cooling — often via ductless heat pumps — increasingly common. Use our HVAC Installation Cost Calculator to estimate adding a system.
Seattle's mild winters and growing cooling needs make heat pumps one of the most efficient options for the region, handling both heating and AC in one system. See potential savings with our Heat Pump Savings Calculator.
Seattle homeowners typically spend $4,500-$9,500 on furnace or heat pump replacement, reflecting regional labor costs. Try our Furnace Replacement Cost Calculator for a closer estimate.
