In the “Auto” position, the fan should cycle on only when there is a call for cooling. The fans in the outdoor unit must also run in order to draw the outside air across the coils where the refrigerant absorbs its heat through evaporation and then takes it indoors.

Heat Pump Indoor Fan Runs Continuously When the refrigeration part of the heat pump has a problem the auxiliary heating will kick when the offset temperature is achieved. Other Reasons Your Heat Pump Runs Continuously. While the air flows through the coil with the limited capacity, it lessens the unit’s efficiency.

The heat pump is very efficient so make it do its thing. The problem, as confirmed by the experts, is not that the unit is running longer, but when it literally never stops, the thermostat setting is not reached, and you are not comfortable. You can clean the coils and filters by yourself by washing them down. The HVAC unit will thank you for it too. This is, however, the way heat pumps are designed to … During cold weather, the heat pump’s compressor (which is housed in the outdoor unit) will still run in order to place the refrigerant under high pressure and high heat. In the “On” position, the fan will run continuously. Before you call for service, make sure the heat pump isn’t accidentally set to a/c mode, and that the set temperature is correctly set at the thermostat. HVAC units usually break down because dirt and other debris clog the air filters and coils, and restrict the airflow. But some problems are better off left with HVAC maintenance.
