A heat pump is an air conditioner that also runs backwards
Many homes in the Valley heat and cool with a heat pump: the same outdoor unit moves heat out of the house in summer and pulls heat in during winter. A reversing valve switches between the two. Because the system works year-round, it builds up more running hours than an AC that rests over the winter.
Problems that are specific to heat pumps include a stuck reversing valve, a defrost control that doesn't clear ice in cold mornings, and backup electric heat strips that run when they shouldn't, which shows up on the power bill. A technician tests each mode, not just the one that is failing today.

Before you call
What to check first
- Check that the thermostat is set to the right mode (Heat, Cool or Auto) and is set for a heat pump.
- Check both breakers: the outdoor unit and the indoor air handler, which may have its own for the heat strips.
- A little frost on a cold morning is normal; the unit should clear it in a defrost cycle. Thick ice that stays is not.
- Replace a dirty filter. Poor airflow causes problems in both modes.
- Note whether your power bill jumped. Heat strips running constantly is a common sign of a fault.
What heat pump repair covers
What a heating and cooling contractor should do, so you know what to expect and what to ask.
Both modes tested
Heating and cooling are checked, since a fault in one often points to a shared part.
Reversing valve
If the system is stuck in one mode, the valve or the solenoid that switches it may have failed.
Defrost controls
The defrost board and sensors clear ice from the outdoor coil. When they fail, the coil ices over.
Backup heat strips
Electric strips help on cold mornings. Running too often wastes power and can mean the heat pump isn't doing its share.
Motors and capacitors
The same electrical failures that stop an AC stop a heat pump.
Refrigerant
Low charge hurts heating as well as cooling. A leak needs finding, not just topping up.

Costs
Heat Pump Repair: typical planning ranges
| Job | Typical planning range | What moves the price |
|---|---|---|
| Defrost board or sensor | $200 – $650 | Part, access, model |
| Reversing valve replacement | $700 – $2,000 | Brazing, recovery and recharge, refrigerant type |
| Compressor replacement | $1,800 – $4,500+ | Size, warranty status, refrigerant |
Typical planning ranges for common jobs, not quotes, local averages or price guarantees. The contractor prices your job after looking at the system; equipment size, brand, refrigerant type and access all change the figure.
Questions
Heat Pump Repair: common questions
Is steam from the outdoor unit in winter normal?
Yes, during a defrost cycle. The unit briefly reverses to melt frost from the coil and the meltwater can steam. It should stop after a few minutes.
Why is my power bill so high in winter?
Electric backup heat strips may be running more than they should, because of a thermostat setting, a defrost fault or a heat pump that isn't keeping up. A technician can check.
Should I repair or replace an old heat pump?
Because it runs all year, a heat pump often wears out sooner than an AC that only cools. Age, repair cost and refrigerant type are the main factors.
