In short
What heat pump repair covers
Heat pump repair means finding and correcting the fault in an air source system that won't heat, won't cool, gets stuck in defrost, runs constantly or leans too hard on backup heat. It is for homeowners with an existing heat pump, including dual fuel setups paired with a gas furnace. This site connects callers with independent providers who do the work.
Heat pumps move heat instead of making it. In summer they pull heat out of the house like an air conditioner; in winter they reverse and bring heat in from outdoor air. Because one outdoor unit handles both seasons, it rarely gets a long rest.
Some heat pump behavior surprises homeowners but is normal, like steam rising from the outdoor unit during defrost or air that feels warm rather than hot. For cooling-only systems, see AC repair instead.
Signs homeowners notice
Signs your heat pump may need repair
- The outdoor unit stays covered in thick ice for hours instead of clearing during defrost.
- Air from the vents feels cool in heating mode, not just mildly warm.
- The aux heat light on the thermostat stays on for long stretches, even in mild weather.
- The system won't switch between heating and cooling.
- Outside of a defrost cycle, the outdoor fan stays still while the compressor hums.
- Grinding, screeching or banging comes from the outdoor unit.

What a technician may check
What a technician may check
- The reversing valve and its control, which switch the system between heating and cooling.
- The defrost control and sensors that decide when to melt ice off the outdoor coil.
- Refrigerant pressures and temperature readings in both modes when the weather allows.
- Backup electric heat and the relays or sequencers that switch it.
- Thermostat settings, which differ for heat pumps.
- The indoor air handler, coil and filter for airflow problems.
How a heat pump service call usually goes
The technician typically starts at the thermostat and then watches the system in the mode that is failing. Notes like 'iced over overnight' or 'aux heat on all afternoon' help narrow the cause.
Repairs range from a failed defrost sensor or capacitor to reversing valve or refrigerant work, and refrigerant handling stays with the provider. If your heat pump pairs with a gas furnace, the technician may also check the controls that decide which heat source runs.

Repair or replace a heat pump?
A heat pump that has served well and needs a fan motor, sensor or capacitor is usually worth repairing. These are common parts.
A compressor failure, a major refrigerant leak in an older unit, or repeated breakdowns make replacement worth discussing. Ask the provider to explain the condition of both the indoor and outdoor sections, since they work as a matched pair.

Safe checks a homeowner can make
- Confirm the thermostat mode matches the season and the setpoint makes sense.
- Replace a dirty air filter; heat pumps are sensitive to restricted airflow.
- With the system off at the thermostat, brush away snow, leaves and yard debris piled against the outdoor cabinet.
- Check the breaker and outdoor disconnect, resetting a tripped breaker once only.
When professional help makes sense
Call when the outdoor coil remains iced for hours, the system blows cool air in heat mode, backup heat seems to run constantly, or the breaker trips again. Do not chip ice off the coil or pour hot water on it; that can damage the fins and tubing.
If heat is out completely in freezing weather and vulnerable people are at home, say so on the call. The urgent HVAC repair guide explains what counts as urgent.

Heat pumps in a humid, changeable climate
Heat pumps are a common choice in Kentucky and Southern Indiana, where much of the heating season is fairly moderate. During colder snaps they lean more on defrost cycles and backup heat, which is when control and sensor faults tend to appear.
Some homes in the region pair a heat pump with a gas furnace, while others rely on electric backup strips. A backup heat fault can look a lot like a heat pump problem, so the technician checks both.

Related problems
Some frost on the outdoor unit is expected in cold, damp weather, and the system clears it with periodic defrost cycles. Thick ice that stays for hours, or a unit encased in ice, usually means a defrost or airflow problem worth a service call.
Heat pumps deliver air that is warm but not as hot as a furnace, so it can feel cool even when working properly. If the house falls short of the thermostat setting, or the air feels truly cold, a refrigerant, reversing valve or defrost issue may be involved and a technician should check it.
That setting shuts the heat pump off and relies on backup heat alone. It is meant for times when the heat pump has failed. With electric backup strips, running it for long periods uses a lot of electricity, so if you have switched to it, that is a good moment to call for a repair.
Usually, yes. Independent HVAC providers who work on dual fuel systems handle both the heat pump and the gas furnace that backs it up. Mention both when you call.
