Heat pump repair cost: 2026 price guide
Most heat pump repairs cost $150 to $700. Because a heat pump handles both heating and cooling, a single failed part can knock out comfort year-round, not just one season.
A heat pump is mechanically similar to a central AC system, but it reverses to provide heat in cooler months — meaning it runs more hours per year than an AC-only system and a furnace combined. That extra duty cycle is part of why heat pump repairs, while similar in nature to AC repairs, tend to come up more often.

Price factors
What drives the price up or down
Year-round runtime
Heat pumps run more total hours annually than AC-only or furnace-only systems, accelerating wear on moving parts.
Cold-climate strain
In sub-freezing climates, heat pumps work harder and rely more on the defrost cycle, which is a common failure point.
Reversing valve condition
This is the part that switches between heating and cooling — it’s unique to heat pumps and one of the pricier components to replace.
Age & refrigerant type
Older units using legacy refrigerant cost significantly more to service — see our refrigerant cost guide for specifics.
Common questions
Frequently asked questions
This can be normal briefly during a defrost cycle, but if it’s constant, a stuck reversing valve or low refrigerant is the likely cause — both require a technician.
A thin layer of frost that clears during normal defrost cycles is expected in cold weather. Heavy, persistent ice buildup usually points to a defrost control or sensor issue.
Broadly similar for shared components (capacitors, motors, refrigerant), but heat pumps have a few unique, pricier parts like the reversing valve and defrost board that neither a standalone furnace nor AC has.
