Heat Pump Repair & Replacement in Seattle, WA

Heat pump repairs in Seattle range from $150 for a basic capacitor replacement to $1,500+ for major component repairs (compressor, refrigerant leak repair with significant recharge, defrost board replacement). Most common repairs — capacitors, contactors, sensors — fall in the $150-$500 range. Full replacements run from $11,500 to $18,400 depending on equipment tier and scope. We provide written quotes before any repair work begins.

Yes. The mechanical permit is issued by Seattle Department of Construction & Inspections (SDCI), and Washington State requires one for this work. We handle the whole thing — application, fee, and meeting the inspector for the final — so you never contact the permit desk yourself. In Seattle, exterior equipment may additionally need sign-off from the Seattle Landmarks Preservation Board and the neighborhood historic districts (Ballard Avenue, Columbia City, Pioneer Square, Harvard-Belmont), which we factor into placement before we quote. Every install meets or exceeds the current Washington State mechanical and energy codes.

Most heat pump repairs in Seattle are completed same-day, often within an hour or two of arrival. We carry common failure parts (capacitors, contactors, common sensors) on the truck. Repairs requiring special-order parts (specific control boards, specific compressors) typically take 2-5 days for parts arrival. Full system replacements run 1-2 days.

Use the 50% rule and the age rule. If the repair quote exceeds 50% of replacement cost, replace. If the unit is 12+ years old AND the failure is a major component (compressor, evaporator coil, condenser coil), replace. If the unit uses R-22 (Freon) refrigerant, replace — R-22 is phased out and refilling it is expensive and impractical. Below those thresholds, repair almost always wins.

We install Day & Night, Carrier, Mitsubishi, American Standard, and Daikin as our primary replacement brands — selected for Seattle-climate reliability and strong manufacturer support.

Some ice on the outdoor coil during Seattle's damp winter weather is normal — heat pumps run a defrost cycle every 30-90 minutes to clear it. Constant heavy icing usually points to: a failed defrost board or sensor, low refrigerant charge, restricted airflow (blocked outdoor coil, dirty filter), or a stuck reversing valve. Don't pour hot water on it — that can crack the coil. Call us for a diagnostic.

The Washington State Energy Code lists Seattle at a 24°F winter design temperature (WAC 51-11C-80100, Table C-1). That is the number a Manual J load calculation for your home is run against, and it is the difference between equipment that carries the house on its own and equipment that leans on expensive backup heat every cold snap. A cold-climate heat pump holds its rated capacity well below that, which is why heat pumps genuinely work here rather than being a compromise. Gas here comes from Puget Sound Energy, and for some homes a hybrid — heat pump for most of the year, gas furnace for the coldest mornings — is the right answer. We will tell you if it is.
