Heat Pump Repair & Replacement in SeaTac, WA
Expert diagnostics and repair for all heat pump brands serving Angle Lake, McMicken Heights, Bow Lake, and all of SeaTac.

Served by Puget Sound Energy or Seattle City Light depending on the address — we confirm which before quoting a rebate.
Your SeaTac Heat Pump Repair Team
SeaTac homeowners in Angle Lake, McMicken Heights, and Bow Lake rely on their heat pumps year-round — for heating from October through April, cooling from June through September, and shoulder seasons in between. When something stops working, you need a fast diagnosis and a straight answer.
SeaTac is the code table station — the 24°F design temperature every neighboring city borrows is measured at the airport here — and many homes were re-insulated under the Port sound-insulation program, which changes the load calculation. Because the boundary runs through SeaTac rather than around it, the first thing we do is read your power bill — quoting a rebate you cannot claim is not a favour.
The Washington State Energy Code lists SeaTac 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. Natural gas here comes from Puget Sound Energy. In SeaTac we most often find electric baseboard and wall heaters in the 1950s–70s ramblers, gas forced air in split-levels, and Port of Seattle sound-insulation-program windows and insulation that changed the original load — so we quote what your house actually has, not what the average Puget Sound home has.

Understand Local Homes
In SeaTac we usually find electric baseboard and wall heaters in the 1950s–70s ramblers, gas forced air in split-levels, and Port of Seattle sound-insulation-program windows and insulation that changed the original load. We size to your house at the 24°F design temperature the state energy code sets for this area — not to a rule of thumb.
Common Heat Pump Issues in SeaTac
Who bills you for power decides what you can claim. SeaTac is served by Puget Sound Energy or Seattle City Light depending on the address. PSE's current heat pump incentive is if PSE is the name on your power bill, up to $4,400 toward a qualifying heat pump replacing an existing electric or fossil-fuel system — the exact amount depends on what you are replacing and the equipment you install. PSE pays $1,500 for an electric-resistance conversion plus a $2,400 income-based boost; Seattle City Light runs its own program. We confirm which one you are on before quoting. Both programs pay only through their own approved installer lists — PSE has required a Trade Ally or Registered Energy Professional since April 2, 2026 — so the utility on your bill decides both the amount and who is allowed to earn it for you.
SeaTac does not share Seattle's weather, and the code says so. The Washington State Energy Code lists SeaTac 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. Kent is 21°F — a real gap for towns this close together. SeaTac is the milder side of that line, and equipment sized for the colder neighbor is equipment you paid too much for.
What we expect to find in a SeaTac home. The local stock runs to 1950s-1970s ramblers and split-levels, apartment complexes, and moderate-density housing near the airport. That usually means electric baseboard and wall heaters in the 1950s–70s ramblers, gas forced air in split-levels, and Port of Seattle sound-insulation-program windows and insulation that changed the original load. Gas service here comes from Puget Sound Energy. Whether repairing or replacing a heat pump is the right answer for your house is something we tell you after we look at it, not before.
The parts of the job that are specific to this address. In SeaTac, the mechanical permit is issued by the City of SeaTac Community & Economic Development Department, and we pull it, pay it and meet the inspector; burn bans and wildfire-smoke advisories here are called by Puget Sound Clean Air Agency, which is the season that makes filtration worth specifying properly.

Heat Pump Questions from SeaTac Homeowners
Heat pump repairs in SeaTac 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 $10,000 to $16,000 depending on equipment tier and scope. We provide written quotes before any repair work begins.
Yes. The mechanical permit is issued by the City of SeaTac Community & Economic Development Department, 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. Every install meets or exceeds the current Washington State mechanical and energy codes.
Most heat pump repairs in SeaTac 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.
Varsity Heating and Cooling services every major heat pump brand sold in SeaTac: Day & Night, Carrier, Mitsubishi, American Standard, Daikin, Trane, Lennox, Rheem, Goodman, and others. We install Day & Night, Carrier, Mitsubishi, American Standard, and Daikin as our primary replacement brands — selected for SeaTac-climate reliability and strong manufacturer support.
Some ice on the outdoor coil during SeaTac'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 SeaTac 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.
