Common heat pump problems
- Thick ice on the outdoor unit that won't clear: defrost control, sensor or refrigerant issues
- Blowing cool air in heat mode: reversing valve, refrigerant charge or thermostat setup
- Furnace not taking over in deep cold: dual-fuel settings or outdoor sensor
- Unit won't start: capacitor, contactor, breaker or control board
- Loud noises or vibration from the outdoor unit
Some frost is normal
A thin layer of frost in winter is normal, and the unit will run short defrost cycles that may release steam. Heavy ice that stays, or ice on the top of the unit, needs service.
Keep it clear
Keep snow clear of the unit and make sure roof runoff isn't dripping onto it. Never chip ice off the coil.

Heat pump repair FAQs
Still unsure? Call 587-719-5115 and talk to a technician.
Why is my heat pump covered in ice?
Light frost is normal and clears during defrost cycles. Heavy ice that doesn't clear usually points to a defrost control, sensor, airflow or refrigerant problem.
Why is my heat pump blowing cold air in winter?
It may be in a defrost cycle, which is normal and brief. If it lasts, the reversing valve, refrigerant charge or thermostat settings may need attention.
How often should a heat pump be serviced?
Once a year. Because it runs in both seasons, it gets more use than an air conditioner.
