AC out, blowing warm, or iced over
Outdoor unit silent · indoor blower running but warm air · ice on the refrigerant lines · short-cycling on/off. Possible causes range from electrical parts (capacitor, contactor) to a refrigerant problem — both need a technician to diagnose.
Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. If you smell gas, leave the building right away without flipping switches or using phones inside, then call 911 or your gas utility’s emergency line from outside.
Banging, screaming, or grinding outdoor unit
Loud bangs · metal-on-metal screaming · grinding or rattling from the outdoor unit. Possible causes include a failing fan motor, a loose blower wheel, or worn compressor bearings. Turn the system off at the thermostat and call a technician.

Seattle's marine coastal climate & your HVAC

Seattle had an estimated 784,777 residents on July 1, 2025. In Seattle, the median home was built in 1974 with a current median value of $912,100. Around 44% of homes are owner-occupied. About 34% of households heat with natural gas vs. 60% electric. The Washington grid averages $0.14/kWh.

HVAC in Seattle, WA: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the Washington licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Seattle-Tacoma International Airport (KSEA) is the NOAA reference station for the city. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00024233), Seattle records an annual mean temperature of 53.7°F, approximately 4,375.8 annual heating degree days against only 265.0 cooling degree days, 39.34 inches of annual precipitation, and 6.3 inches of snowfall. The 16:1 HDD-to-CDD ratio makes Seattle heating-dominated — but the mild marine climate (neither extremely cold in winter nor extremely hot in summer) places it squarely in DOE’s ideal heat-pump territory. Damp near-freezing winter conditions are the dominant HVAC design constraint, not absolute cold.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for Seattle city, Washington) report 353,019 occupied housing units with a median year built of 1974. Heating-fuel distribution is unusual: 59.7% electricity (210,693 units) dominates, with only 33.8% utility natural gas (119,194 units) and 11,421 units on fuel oil. Seattle is one of only a handful of major U.S. cities where electric heating is the majority — the direct consequence of Seattle City Light’s abundant low-cost hydroelectric power. For homeowners, this has a practical implication: converting from electric baseboard to a modern heat pump delivers far greater efficiency gains in Seattle than in gas-dominant cities, because the electric resistance baseline is so energy-intensive.
Washington State Legislature
Every HVAC/refrigeration contractor working in Seattle must hold a current 06A HVAC/Refrigeration specialty license from the Washington State Department of Labor & Industries (L&I). Per Washington Administrative Code Section 296-46B-920, the 06A specialty “is not limited by voltage, phase, or amperage” and covers “installation, repair, replacement, and maintenance of line voltage components within HVAC/refrigeration equipment” as well as “repair, replacement, or maintenance of line voltage flexible supply whips not exceeding six feet in length.” Verifying a contractor’s active 06A credential via L&I’s license-lookup tool before authorizing work is the baseline due-diligence step. Permit fees for residential mechanical work are set by the Seattle Department of Construction & Inspections (SDCI); contact SDCI at (206) 684-8600 for the current mechanical permit fee schedule.
City of Seattle Permitting
Per Seattle City Light’s Home Energy Solutions page, residential heat-pump instant discounts are tiered by HSPF2 efficiency: HSPF2 8.1 or higher: $300 instant discount; HSPF2 8.5 or higher: $400; HSPF2 9.5 or higher: $600. Separately, homeowners can receive “$750 rebate on heat pump water heaters” and a “$50/unit instant rebate courtesy of Seattle City Light” for smart thermostats designed for electric baseboard heaters (through December 31, 2026). For current natural-gas furnace, boiler, and heat pump rebate amounts from Puget Sound Energy (PSE), see pse.com/rebates directly. The federal Section 25C tax credit was terminated for installations after Dec 31, 2025 (OBBBA, P.L. 119-21).
The federal Section 25C Energy Efficient Home Improvement Credit was terminated for installations placed in service after Dec 31, 2025 by the One Big Beautiful Bill Act (Public Law 119-21). Check your state energy office and utility for current rebate programs. See our HVAC financing options for what's still available.
