When a Redmond heat pump needs repair
Most heat pump failures start small. These are the warning signs Redmond homeowners describe to us most often:
- The vents blow cool air in heat mode for more than a few minutes.
- A thick layer of ice stays on the outdoor unit after it defrosts.
- The aux heat light stays on, and the PSE bill climbs with no change in use.
- The outdoor unit does not start even though the thermostat is calling.
- New noises: humming from a ductless head, grinding from a fan, or a loud bang at startup.
- The breaker trips more than once.
- A ductless head drips water or flashes a light code.
Safe checks before you call
- Set the thermostat to heat, raise the setpoint a few degrees and check the batteries.
- Look at the breaker and the outdoor disconnect. Reset once only.
- Change a dirty filter.
- Clear fir needles, leaves and snow from the outdoor coil, and give an iced unit time to finish defrosting. Never chip the ice.

Heat pump problems we fix in Redmond
Redmond has a wide mix of homes, from older houses on Education Hill to newer homes and townhomes near Downtown and Overlake, and many use heat pumps, ductless systems or a heat pump paired with a PSE gas furnace. Evergreen debris on outdoor coils and long, damp heating seasons are part of the job here.
| Problem | What usually causes it | What we do |
|---|---|---|
| Outdoor unit will not start | Failed capacitor, contactor or outdoor control board | Trace the low-voltage signal and test each part before replacing anything |
| Ice that will not clear | Defrost board or sensor, low airflow, low refrigerant | Check the defrost cycle, coil and refrigerant charge |
| Cool air in heat mode | Reversing valve, refrigerant leak, thermostat settings | Test the valve and pressures; find and repair leaks |
| Ductless head noise or leak | Indoor fan motor bearings, clogged or unlevel drain | Inspect the blower and drain; order warranty parts when covered |
Ductless and mini-split repair in Redmond
We repair single and multi-head ductless systems, from a head that hums or drips to a system that will not respond. Home Comfort Alliance is a Mitsubishi Electric Diamond Dealer and services all major brands.
Dual-fuel systems with a gas furnace
A dual-fuel system lets the furnace heat the house while the heat pump side is down. We repair the outdoor unit, defrost controls, reversing valve and refrigerant side here; for the furnace side, see furnace repair in Redmond.
After-hours emergency heat pump repair in Redmond
Heat pumps tend to fail on the coldest nights, and we answer the phone when they do. We offer after-hours emergency HVAC service in Redmond, with a $330 after-hours fee stated up front. Call right away for no heat in freezing weather, a burning smell, or a breaker that will not stay on.
Until we arrive, switch the thermostat to emergency heat and keep pets and children away from an iced or noisy outdoor unit. More steps are on our after-hours emergency heat pump repair page.
Should you repair or replace your heat pump?
For a reliable system with one failed part, repair is usually the right call. These point toward replacement:
- A failed compressor or outdoor coil on an older unit.
- An R-22 system, since that refrigerant is no longer made.
- Age times repair cost above $5,000 (the $5,000 rule).
- Repeat repairs, or backup heat running most of the winter.
Repairs are not eligible for rebates. Replacements in Redmond may be: PSE, which supplies electricity and gas here, offers $1,500 to upgrade an out-of-warranty ducted heat pump to a qualifying cold-climate model, $1,500 to convert electric resistance heat, and $1,500 to add a heat pump to a PSE gas furnace, each with a $2,400 income-based Efficiency Boost. Inside Redmond city limits, Energy Smart Eastside adds a $1,000 instant rebate when a heat pump replaces a furnace or electric resistance heat, with an income-qualified bonus for a total of up to $6,000. Amounts read October 2026. We are a PSE Trade Ally and handle the PSE rebate paperwork.
Replacement estimates are free, and our instant quote gives a price range in about 30 seconds. Learn more about heat pump installation in Redmond or our heat pump cost guide. A replacement inside city limits needs a City of Redmond mechanical permit through the Redmond ePermitting Service; Redmond addresses in unincorporated King County are permitted by King County. We pull the permit either way.

A recent Redmond heat pump repair
In September a Redmond homeowner called because the thermostat was calling but the heat pump's outdoor unit never started, and there was no error code. Our technician traced the low-voltage control signal: it reached the outdoor control board but never left it for the contactor, so the board had failed. The home has a dual-fuel system, so the family ran the gas furnace on emergency heat while the part came in. On the return visit he installed a new outdoor control board, which was out of warranty, and tested the system through a full cycle.

Redmond heat pump repair FAQ
How much does heat pump repair cost in Redmond?
Our dispatch fee is $119 and a standard diagnostic is $72; a deeper diagnostic is $130. You get a written price for the repair before any work begins. As a regional estimate, most Seattle-area heat pump repairs cost $220 to $2,220 (Angi, May 2026).
Is there a charge to come out?
Yes. The $119 dispatch fee and the $72 standard diagnostic are separate charges, and after-hours visits add $330. Estimates for a replacement are free.
Do you offer after-hours emergency heat pump repair in Redmond?
Yes. We offer after-hours emergency HVAC service in Redmond, with a $330 after-hours fee. Our office is open Monday to Friday, 8 AM to 5 PM.
Why is my heat pump blowing cold air?
A heat pump blows cooler air than a furnace, and it blows cool air for a short time during a defrost cycle. If it stays cold, check the thermostat mode, the breaker and the filter, then call us to test the reversing valve and refrigerant.
Why is my outdoor unit covered in ice?
Light frost is normal and should clear during defrost. A thick block of ice that stays usually means a defrost control, airflow or refrigerant fault. Do not chip it; switch to emergency heat and call us.
My outdoor unit will not turn on. What could it be?
Common causes are a tripped breaker or disconnect, a failed capacitor or contactor, or a failed outdoor control board. A technician tests the control signal and each part before replacing anything.
Do you repair ductless mini-splits?
Yes. We repair single and multi-head ductless systems. We are a Mitsubishi Electric Diamond Dealer and service all major brands, and we order warranty parts when your system is still covered.
Who fixes a dual-fuel system with a gas furnace?
We do both sides. Our technicians repair the heat pump and the gas furnace, and on a dual-fuel system the furnace can keep the house warm while a heat pump part is on order.
Should I repair or replace my heat pump?
Multiply the age of the unit by the repair cost. If the result is over $5,000, replacement is often the better value. A failed compressor or an R-22 system also points to replacement. We give free estimates on replacements.
What rebates are available if I replace my heat pump in Redmond?
Repairs do not qualify. For a replacement, PSE offers $1,500 to upgrade an out-of-warranty ducted heat pump to a qualifying cold-climate model, plus a $2,400 income-based Efficiency Boost. Homes inside Redmond city limits switching from a furnace or electric heat may also get a $1,000 Energy Smart Eastside instant rebate. Amounts read October 2026.
Do I need a permit to replace a heat pump in Redmond?
Yes. Inside city limits the City of Redmond issues the mechanical permit; Redmond addresses in unincorporated King County get it from King County. We pull the permit on every installation.
Are your technicians licensed?
Yes. Our technicians are NATE-certified, and we are licensed, bonded and insured in Washington: Contractor Reg. #HOMECCA785BD and Electrical Contractor Lic. #HOMECCA782DC.
