Signs your Bellevue heat pump needs repair
Bellevue's damp, mild winters keep a heat pump running for long stretches, so small faults show up fast. Call us if you notice any of these:
- Cool or lukewarm air in heat mode that lasts more than a few minutes.
- Ice on the outdoor unit that does not clear after a defrost cycle.
- The system runs nonstop on a mild day, or the aux heat light stays on.
- A PSE bill that jumps with no change in how you use the house.
- A breaker that trips more than once.
- Grinding, buzzing or a loud bang when the outdoor unit starts.
- Water dripping from a ductless head, or a blinking light on it.
Quick checks before you call
- Confirm the thermostat is set to heat and the batteries are good.
- Check both breakers and the outdoor disconnect. Reset once only.
- Replace a dirty filter.
- Clear leaves, fir needles and moss from around the outdoor unit. Never chip ice; give the defrost cycle 10 to 15 minutes.
More troubleshooting is in our heat pump repair guide.
Heat pumps we repair in Bellevue
Bellevue has everything from mid-century ramblers and split-levels with gas furnaces to newer homes, condos and townhomes on ductless systems. We work on all of them.
| Problem | Common cause | What we check |
|---|---|---|
| Outdoor unit will not start | Capacitor, contactor, control board | The control signal and each part, before anything is replaced |
| Ice that keeps building | Defrost board or sensor, low airflow, low refrigerant | The defrost cycle, coil, filter and refrigerant charge |
| Cool air in heat mode | Reversing valve, refrigerant leak, metering device | Pressures, subcooling and superheat, and the valve |
| Short cycling or a high bill | Thermostat setup, sensors, aux heat staging | Thermostat settings and backup heat lockouts |
Ducted heat pumps
We repair capacitors and contactors, defrost boards, reversing valves, expansion valves, refrigerant leaks, fan motors and sensors. Most common parts are on the van.

Repair or replace your heat pump?
For a reliable system with one failed part, repair is usually the better value. These point toward replacing:
- The compressor or outdoor coil fails on an older system.
- The system uses R-22, which is no longer made.
- The age of the unit times the repair cost is more than $5,000.
- Repairs keep coming back, or backup heat carries most of the winter.
Repairs do not qualify for rebates. When a new heat pump replaces a gas furnace or electric resistance heat inside Bellevue city limits, Energy Smart Eastside offers a $1,000 instant rebate through approved contractors, plus a bonus of up to $5,000 for income-qualified, fully electric homes. PSE, which supplies Bellevue's electricity and gas, offers $1,500 for converting electric resistance heat and $1,500 for adding a ducted heat pump to a PSE gas furnace, with a $2,400 income-based Efficiency Boost. Amounts read October 2026. Home Comfort Alliance is an Energy Smart Eastside approved contractor and a PSE Trade Ally. If you are replacing an existing heat pump, ask us which programs apply before you plan around a rebate.

How a Bellevue heat pump repair visit works
Bellevue permits: the City of Bellevue requires a mechanical permit to install or replace a heat pump, and an electrical permit when wiring is part of the job. Part-only repairs do not need a permit. We pull the required permits for every installation. Here is what happens on a repair call.
- Call or book online. Our phones are answered 24/7, and we confirm an arrival window.
- Diagnose. A NATE-certified technician checks heating and cooling modes, refrigerant pressures, electrical parts, the defrost cycle, backup heat and airflow.
- Upfront price. You get a written price, and repair-or-replace advice when it applies, before any work begins.
- Repair. Most common parts are on the van, so many repairs finish on the first visit.
- Test and review. We run a full heating cycle, including a defrost check, and walk you through what we found.
A recent Bellevue heat pump repair: south Bellevue
In early October 2026 our technician returned to a south Bellevue home (98006) to replace a faulty indoor expansion valve on a Carrier heat pump. That valve meters refrigerant into the indoor coil, and when it fails the system cannot heat or cool properly. He recovered the refrigerant, opened the indoor coil cabinet, and purged the lines with nitrogen while removing the old valve and the bi-flow filter drier at the outdoor unit. With the new valve and drier brazed in, he evacuated the system to 250 microns, recharged it and confirmed 13 degrees of subcooling on the test run.

Bellevue heat pump repair FAQ
Who do I call for heat pump repair in Bellevue at night?
Call Home Comfort Alliance. We offer after-hours emergency HVAC service in Bellevue. An after-hours fee of $330 applies.
How much does heat pump repair cost in Bellevue?
It depends on the part that failed. Our dispatch fee is $119 and our standard diagnostic is $72, and you get an upfront price before any work begins. Angi puts most Seattle-area heat pump repairs at $220 to $2,220 (regional estimate, May 2026).
Is there a charge for a heat pump repair visit?
Yes. The dispatch (trip) fee is $119. A standard diagnostic is $72 and a deeper diagnostic is $130. After-hours visits carry a $330 fee. Replacement estimates are free.
Why is my heat pump blowing cold air?
First check that the thermostat is set to heat. In cold, wet weather the unit may be in a defrost cycle, which can blow cool air for a few minutes. If it lasts longer, the cause may be a reversing valve, low refrigerant or a failed expansion valve, and a technician should diagnose it.
Why is my heat pump covered in ice?
Some frost in winter is normal, and the defrost cycle should clear it. Ice that stays or keeps building points to a defrost, airflow or refrigerant problem. Do not chip the ice. Switch to emergency heat and call us.
What is emergency heat or aux heat?
It is your backup heat, usually electric strips or a gas furnace. Aux heat helps the heat pump in very cold weather. Emergency heat runs the backup alone. Use it while you wait for a repair, because backup heat alone costs more to run.
Do you repair ductless mini-splits in Bellevue?
Yes. We repair ductless and mini-split systems, including multi-zone systems with one head not working. We are a Mitsubishi Electric Diamond Dealer and we service all major brands.
Do you repair heat pumps paired with a gas furnace?
Yes. Many Bellevue homes run a heat pump with a PSE gas furnace as backup. We check the heat pump, the furnace and the switchover between them. For a furnace-only problem, see furnace repair in Bellevue.
Should I repair or replace my heat pump?
Repair is usually right if the system has been reliable and the fix is small. Consider replacing if the compressor or coil fails on an older system, it uses R-22, or the age times the repair cost is more than $5,000. We give you both options before work starts, and replacement estimates are free.
Do heat pump repairs qualify for Energy Smart Eastside or PSE rebates?
No. Rebates apply to new equipment, not repairs. Energy Smart Eastside offers a $1,000 instant rebate when a qualifying heat pump replaces an existing furnace or electric resistance heat in Bellevue, plus a bonus of up to $5,000 for income-qualified, fully electric homes. Home Comfort Alliance is an Energy Smart Eastside approved contractor.
Do I need a permit to replace a heat pump in Bellevue?
Yes. The City of Bellevue requires a mechanical permit to install or replace a heat pump, and an electrical permit when wiring is part of the job. Applications go through MyBuildingPermit.com. Part-only repairs, such as a capacitor, control board or fan motor, do not need a permit. We pull the required permits for every installation.
