Angi’s Seattle part figures cover HVAC repairs in general, not only heat pumps. Third-party figures are estimates, not our prices.
Compressor
The most expensive repair: $650 to $2,400 nationally (Angi, October 2026), $900 to $2,900 in Seattle (Angi, May 2026) and $800 to $3,500 (HomeAdvisor, June 2026). Angi suggests considering replacement when the compressor fails on a system over 12 years old. Check the parts warranty first; see the warranty section below. The usual symptom is an outdoor fan that runs while no heat comes out, or a breaker that keeps tripping.
Reversing valve
Angi puts reversing valve replacement at $200 to $650 nationally. The valve switches the heat pump between heating and cooling, so a stuck valve shows up as a system stuck in one mode. Replacing it means opening the refrigerant circuit, so refrigerant recovery and a recharge are part of the job. If your heat pump blows cold air in heating mode, read why a heat pump blows cold air.
Capacitor and contactor
Seattle: $110 to $280 for a capacitor (Angi); $120 to $400 nationally for a capacitor or contactor (Angi); $150 to $250 for a capacitor (HomeAdvisor). The sign is an outdoor unit that hums but whose fan doesn’t spin. A failed capacitor is a small part, not a sign the heat pump is dying. Capacitors store a charge, so this isn’t a do-it-yourself job.
Defrost board and outdoor fan motor
HomeAdvisor puts a heat pump that won’t defrost at $90 to $650 to fix, a defrost control board at $200 to $650 and a condenser fan motor at $250 to $650. The sign is ice on the outdoor unit that doesn’t clear. Before winter, see how to winterize a heat pump.
Refrigerant leaks
Seattle: $280 to $1,670 to repair a leak and $110 to $555 for a recharge (Angi, May 2026). Refrigerant doesn’t get used up, so a low charge means a leak. EPA advises asking technicians to locate and repair the leak instead of just topping it off.
By system size
| System size | Repair cost range |
|---|---|
| 1.5 to 2 tons | $175 to $800 |
| 2.5 to 3 tons | $250 to $1,000 |
| 4 to 5 tons | $350 to $1,500 |
National estimate, Angi, October 2026.
Ducted vs ductless (mini split) repair costs
HomeAdvisor puts air-source heat pump repairs at $200 to $1,600 and ductless mini split repairs at $100 to $1,500 (national estimate, June 2026). Angi’s Seattle estimate for mini split repair is $330 to $610 (May 2026). Common ductless repairs are clogged condensate lines, dirty indoor coils and blower wheels, sensor or communication errors and leaks at the line set. On a multi-zone system, one outdoor unit serves several indoor heads, so an outdoor failure affects every room. Home Comfort Alliance is a Mitsubishi Electric Diamond Dealer and services all major ductless brands; see ductless systems and our Seattle mini split cost guide.
Will your warranty cover the repair?
Often the part, rarely the labor. Angi notes that most warranties do not cover labor. What the manufacturers say:
- Carrier: 5 years of parts coverage if the system isn’t registered within 90 days; 10 years of parts if it is, or 5 years of parts plus 3 years of labor through participating dealers.
- Lennox: the factory warranty covers parts only; with registration, owners can choose up to 3 years of labor coverage.
- Mitsubishi Electric: 12 years of parts and compressor coverage for single-family homes when a Diamond Contractor or Ductless Pro installs it and it is registered within 90 days.
We support the manufacturer’s warranty on covered parts for the brands we sell and service. Home Comfort Club members with a new system installed by Home Comfort Alliance get extended labor coverage for up to 5 years from installation. More on warranty types: decoding heat pump warranties.
Refrigerant: R-22 and R-410A heat pumps
EPA says production and import of R-22 ended January 1, 2020. Existing R-22 systems can still be serviced with reclaimed and older supply, and EPA does not require homeowners to replace their equipment. Under EPA’s newer rules, new home systems must use refrigerants with a lower global warming potential, but EPA states that components used to repair existing systems are not subject to these restrictions, so an R-410A heat pump can still be repaired.
An R-22 system is often old enough that a big repair is worth comparing with replacement; a small repair can still make sense.
What drives the price
- The part: OEM parts run $100 to $700 and aftermarket parts $75 to $500 (Angi).
- System size and whether it is ducted or ductless, and how many indoor heads it has.
- Refrigerant work: anything that opens the refrigerant circuit adds recovery and recharge.
- Access: roof-mounted units, crawlspaces and tight side yards take longer.
- Warranty status of the part.
- Time of the call: after-hours visits cost more.
- Labor: Angi puts Seattle HVAC labor at $80 to $150 an hour, and labor is 40% to 90% of a typical bill.
After-hours heat pump repair cost
Our phones are answered and bookings are accepted 24/7. Heating and cooling technicians work during business hours and are available after hours for qualifying emergencies, such as a heat pump that has stopped heating in cold weather. The after-hours fee is $330, stated before we come. Angi puts emergency HVAC labor in Seattle at $150 to $275 an hour (May 2026). See emergency heat pump repair for what to check first.
Is it worth repairing a 10-year-old heat pump?
Usually yes for a small repair, and worth a second look for a big one. ENERGY STAR suggests considering replacement once a heat pump is more than 10 years old, especially if it needs frequent repairs and bills are rising. Angi says repair is usually best under 10 years, and to consider replacement past 12 years or when the compressor fails. HomeAdvisor puts average heat pump life at about 14 years, with newer models lasting 20 years or more.
The $5,000 rule, worked out
Multiply the system’s age by the repair cost; if the result is over $5,000, get a replacement quote too. A 10-year-old heat pump needing a $280 capacitor (the top of Angi’s Seattle range): 10 × $280 = $2,800, so repair it. The same heat pump needing a $900 compressor (the low end of Angi’s Seattle range): 10 × $900 = $9,000, so price a replacement too. It is a rule of thumb, not a verdict.
The 50% rule
Angi recommends replacement when a repair costs more than half the price of a new system. For a replacement price, get a range in about 30 seconds with our free instant quote tool, and see our heat pump installation cost guide.
Rebates change the math for PSE customers
Repairs aren’t rebated. But if your ducted, all-electric heat pump is out of its original manufacturer’s warranty and you replace it with a qualifying cold-climate heat pump, PSE offers a $1,500 rebate, plus a $2,400 Efficiency Boost for income-qualified customers. Ductless heat pumps aren’t eligible, and the rebate is only available through a PSE Trade Ally or Recommended Energy Professional. Home Comfort Alliance is a PSE Trade Ally and handles PSE rebate paperwork. Other utilities: see rebates. The federal 25C credit ended for equipment placed in service after December 31, 2025.
When replacement usually wins
- A compressor failure on an older system
- Repeated repairs
- An R-22 system that needs a major repair
- Rising bills
- Parts that are no longer made
If your heat pump is safe and the fix is a small part, repairing it is usually the cheaper choice, and we’ll tell you so. See also signs your heat pump may be failing.

Heat pump repair cost FAQ
How much does it cost to fix a heat pump?
Most heat pump repairs cost $161 to $661, and most homeowners pay about $410 (national estimate, Angi, updated October 2026). In the Seattle area, Angi’s regional estimate for heat pump repair is $220 to $2,220 (May 2026). At Home Comfort Alliance, the dispatch fee is $119 and a standard diagnostic is $72, listed separately, and you approve an upfront price before any work begins.
What is the most expensive heat pump repair?
A compressor replacement usually costs the most: $650 to $2,400 nationally (Angi, October 2026) and $900 to $2,900 in Seattle (Angi, May 2026). Coil replacements and large refrigerant leaks come next. On an older system, a failed compressor is usually the point to compare replacement.
How much does a reversing valve replacement cost?
Angi puts reversing valve replacement at $200 to $650 nationally (October 2026). The valve switches your heat pump between heating and cooling, so a stuck valve often shows up as a system stuck in one mode. Our technician confirms the cause before quoting.
How much does a heat pump capacitor cost to replace?
Angi’s Seattle estimate is $110 to $280 (May 2026), and HomeAdvisor’s national estimate is $150 to $250 (June 2026). A failed capacitor is a common, small repair. Capacitors hold a charge, so leave this one to a technician.
How much does mini split repair cost?
HomeAdvisor puts ductless mini split repairs at $100 to $1,500 nationally (June 2026), and Angi’s Seattle estimate for mini split repair is $330 to $610 (May 2026). Clogged condensate lines, sensor errors and refrigerant leaks at the line set are common causes.
Is it worth repairing a 10-year-old heat pump?
For a small repair, usually yes. ENERGY STAR suggests considering replacement once a heat pump is more than 10 years old, especially with frequent repairs and rising bills, and Angi suggests weighing replacement past 12 years or when the compressor fails. We’ll give you the repair price so you can compare.
How long do heat pumps last?
HomeAdvisor puts the average heat pump at about 14 years, and says newer models can last 20 years or more (June 2026). Yearly maintenance, clean filters and a clear outdoor unit help a heat pump reach the upper end.
Does the manufacturer warranty cover heat pump repairs?
It often covers the part, but usually not the labor. Carrier, for example, gives 10 years of parts coverage when the system is registered within 90 days and 5 years when it isn’t. Lennox’s factory warranty covers parts only, with labor coverage available through registration.
Can an R-22 heat pump still be repaired?
Yes. EPA says R-22 production ended January 1, 2020, but existing systems can still be serviced with reclaimed refrigerant, and EPA doesn’t require you to replace them. Because these systems are older, a large repair is worth comparing with replacement.
Is there a fee to diagnose my heat pump?
Yes. Our dispatch (trip) fee is $119, a standard diagnostic is $72, and a deeper diagnostic is $130 (September 2026). Each fee is listed on its own, and you see the repair price before we start.
Do rebates help pay for heat pump repairs?
Generally no. Utility rebates go to new equipment, and the federal 25C credit ended for equipment placed in service after December 31, 2025. If your ducted, all-electric heat pump is out of its manufacturer’s warranty, PSE offers a $1,500 rebate (plus a $2,400 Efficiency Boost for income-qualified customers) to replace it with a qualifying cold-climate model.
How can I lower my heat pump repair costs?
Get a yearly tune-up ($230, or $180 for Home Comfort Club members), keep filters clean and the outdoor unit clear, and approve repairs only after you see an upfront price. Financing is available from $179/month* (Salal Credit Union or Synchrony, subject to credit approval).
