Heat pumps should be professionally serviced once a year — ideally in fall before heating season begins. Because heat pumps run year-round (both heating and cooling), they accumulate wear faster than systems that only heat or only cool. Annual maintenance extends unit lifespan and prevents costly breakdowns.
Why Annual Maintenance Matters
A heat pump that isn’t maintained regularly loses efficiency over time. Dirty coils, low refrigerant, and worn electrical components force the system to work harder, increasing energy bills and accelerating wear on the compressor — the most expensive component.
Many manufacturer warranties also require documented annual maintenance. Skipping service can void your warranty coverage.
What’s Included in a Heat Pump Tune-Up
- Coil cleaning (indoor and outdoor)
- Refrigerant level check and leak inspection
- Electrical connection tightening and inspection
- Capacitor and contactor testing
- Thermostat calibration and mode testing
- Air filter replacement
- Defrost cycle verification
- Full system diagnostic and performance report
Signs Your Heat Pump Needs Service Now
- Higher than normal energy bills
- Unusual noises (grinding, squealing, rattling)
- Reduced heating or cooling output
- Frequent short cycling (turns on and off rapidly)
- Ice buildup on the outdoor unit
How often should a heat pump be serviced?
Heat pumps should be professionally serviced once a year. Because they run year-round, annual maintenance is the minimum recommended — some manufacturers require it to maintain warranty coverage.
What does a heat pump tune-up include?
A standard heat pump tune-up includes coil cleaning, refrigerant level check, electrical connection inspection, thermostat calibration, filter replacement, and a full system diagnostic.
What time of year should I service my heat pump?
Fall (September–October) is the best time to service a heat pump before heating season. Spring servicing before cooling season is the second best option.
