Heat pumps work year-round to both heat and cool your home, and when they malfunction the impact is felt in every season. Common issues include reversing valve failures, refrigerant leaks, frozen coils, and auxiliary heat strip problems.
Call Durham HVAC Connect and we'll connect you with an HVAC professional serving Durham Region who can diagnose and repair your heat pump.
Because a heat pump is a two-mode system, the troubleshooting is broader than with a furnace or AC alone. The technician typically checks refrigerant pressures in both heating and cooling modes, tests the reversing valve and defrost control, verifies the outdoor unit’s airflow and coil condition, and makes sure backup/auxiliary heat kicks in properly during cold Ontario temperatures. If you notice ice that does not clear during a defrost cycle, or a heat pump that runs constantly, those are worth mentioning when you call.
