Heat pump repair cost
Most heat pump repairs run $150–$650, but a failed compressor can cost far more. Here are typical 2026 prices and how to decide repair vs replace.
Typical heat pump repair prices (2026)
Most service calls land between $150 and $650 including parts and labor. The big exceptions are the compressor and refrigerant leaks.
| Repair | Typical cost |
|---|---|
| Service call / diagnostic | $75–$200 |
| Capacitor | $150–$400 |
| Contactor / relay | $150–$350 |
| Refrigerant recharge + leak repair | $200–$1,500 |
| Defrost control / sensor | $250–$600 |
| Reversing valve | $600–$1,300 |
| Compressor | $1,500–$4,500 |
Repair or replace?
A common rule: if the repair costs more than half the price of a new system and the unit is over 10 years old, replacement usually wins — especially since a new heat pump is far more efficient and may qualify for state/utility rebates. A young unit with a cheap fix is worth repairing. Compare with our cost calculator.
How to keep repair costs down
- Service annually — most failures start as cheap, catchable problems.
- Replace filters regularly to avoid airflow-related breakdowns.
- Keep your warranty valid with registration and professional service.
Frequently asked questions
How much does it cost to repair a heat pump?
Most repairs run $150–$650; a compressor or major refrigerant repair can reach $1,500–$4,500. A diagnostic call is usually $75–$200.
Is it worth repairing an old heat pump?
If the repair exceeds half the cost of a new unit and the system is 10+ years old, replacing is usually the better value — and it qualifies for incentives.
Why is a compressor so expensive?
It is the heart of the system and labor-intensive to swap. On an old, out-of-warranty unit, replacing the whole heat pump often makes more sense.
