Heat pump problems we fix
| Symptom | Usual cause |
|---|---|
| Cools but will not heat (or the reverse) | Reversing valve or its solenoid, thermostat wiring or settings |
| Outdoor unit covered in ice that does not clear | Defrost control or sensor fault, low refrigerant, outdoor fan failure |
| Weak or lukewarm air in heating mode | Low refrigerant from a leak, dirty coil or filter, failing compressor |
| Short cycling, breaker trips | Capacitor, contactor, compressor electrical fault |
| Ductless head dripping or flashing a code | Clogged condensate line, dirty coil, sensor or board fault |
Some steam and a short pause from the outdoor unit in winter is a normal defrost cycle, not a failure.
What to check before you call
- Thermostat in the right mode (heat, cool or auto) and, on heat pump thermostats, not stuck in emergency heat.
- Filter clean; return grilles and outdoor unit not blocked by furniture, leaves or plants.
- Breakers for both the outdoor unit and the indoor air handler on.

Heat pump maintenance
A heat pump works all year, so it wears like two systems. A yearly visit cleans the outdoor and indoor coils, tests the capacitor, contactor and defrost controls, checks refrigerant pressures in both modes and clears the drain. On ductless systems we also clean the indoor heads and their filters.

Repair or replace a heat pump?
A single failed part on a younger system is a repair. A failed compressor on an older system, a system still on R-22 refrigerant, or repeated leaks point to replacement; we price both. See heat pump installation, or for furnace and AC systems, heating repair and AC repair.
What customers say
"If I could give 20 stars I would. 20 stars for customer service alone."
"Honest mechanics in any trade are hard to find; he's definitely one of the good guys!!!"
"Sam was able to diagnose the problem (heat not working since we installed a Nest thermostat) right away..."
Heat pump repair questions
Why is my heat pump blowing cold air in heating mode?
It may be in a defrost cycle (normal for a few minutes), or the reversing valve, refrigerant charge or thermostat setup has a fault. If it does not clear after a short time, call.
Do you repair ductless mini splits?
Yes, including indoor heads that leak water or show error codes.
Is same-day heat pump repair available?
Same-day service is available, and 24/7 emergency heat pump repairs for urgent breakdowns.
