Common heat pump problems
Common heat pump problems we've fixed this week across Northwest Oregon.
Heat pumps are more complex than furnaces — and most repair shops don't train their techs deeply on the variable-speed inverter side. We do.
Heat pump blows cold air in heat mode
Reversing valve stuck, defrost-mode hung, low refrigerant, or a failed compressor solenoid. We chase the actual cause — not "you need a new system."
Outdoor unit iced over
Defrost cycle isn't triggering. Could be defrost sensor, defrost board, or reversing valve. Common Pacific Northwest winter problem with a known fix.
Heat pump won't turn on
Tripped breaker, blown capacitor, dead contactor, or thermostat issue. We check the cheap stuff first and quote flat-rate before any work.
Auxiliary heat running constantly
Heat pump can't keep up: possibly low refrigerant, dirty coils, or a sizing issue from a previous install. Hidden cause of huge electric bills.
Loud noises (hissing, banging, clicking)
Hissing = refrigerant leak. Banging = compressor or fan. Clicking = relay or capacitor. Any of these is a same-day call.
Inverter board / control board errors
Modern variable-speed heat pumps have inverter boards that throw fault codes. We pull codes, diagnose with manufacturer tools, and order the right part.
How a service call goes
Our heat pump repair process — four steps from no-heat to fixed.
- 01
Same-day diagnosis
Most service calls across the metro are scheduled same-day. We dispatch the closest licensed tech.
- 02
Real diagnostics
Refrigerant pressures by mode, defrost sequence test, reversing valve confirmation, electrical at the contactor. We find the actual fault.
- 03
Flat-rate quote, then repair
You see the part cost and labor before we touch a wrench. Most common parts ride with the truck — capacitors, contactors, defrost boards, reversing-valve solenoids.
- 04
Verify & document
After the repair, we run the system through heat AND cool mode, verify defrost, and re-check refrigerant. You get a written report.
- 100% Satisfaction Guaranteed
- Same-day diagnosis
- All major brands
- Flat-rate quotes
On every call
We know these systems inside and out.
Refrigerant pressures by mode, defrost sequence test, reversing valve confirmation, electrical at the contactor. We chase the actual fault and verify the fix before we leave the driveway.
Wherever your system lives
Attics, crawlspaces, mechanical rooms.
Air handlers don't always sit somewhere convenient. We go where the system goes — drop cloths down, vacuum running, clean exit every time. The same respect for your house whether the unit is in the garage or up a pull-down ladder.
Heat pump repair questions, answered.
- Most heat pump service calls across the metro are scheduled same-day. We answer the phone — even after hours when something breaks.
- Most repairs run $200–$800 depending on the part. Major component swaps (compressor, reversing valve, inverter board) run $1,200–$3,500+. We always quote flat-rate before starting work.
- Heat pumps build a small ice layer in heating mode — that's normal, and a defrost cycle melts it every 30–90 minutes. If the unit is fully encased in ice, the defrost cycle isn't running. Defrost board, defrost sensor, or reversing valve. All known fixes.
- Yes. Trane, Mitsubishi, Carrier, Lennox, Goodman, Bryant, American Standard, and others. We have factory training on the major brands and access to manufacturer fault-code documentation.
- Rule of thumb: if the repair is more than 50% of replacement cost AND the system is over 12 years old, replacement usually wins. Especially since modern heat pumps are dramatically more efficient and qualify for big rebates. We model the math at the call.
- Aux heat is normal during very cold weather (below ~30°F) — that's why it exists. But if it's running on a 45°F day, something is wrong. Often a low refrigerant charge, a stuck reversing valve, or an undersized system. Fixing it usually drops your electric bill significantly.
