Why Your Heat Pump Heats When in Cooling Mode

Under normal operation, you expect a heat pump in Spotsylvania, VA, to provide cooling during the hot summer months and heating during the cold winter months. However, you’ll notice that your heat pump sometimes produces warm air instead of cool air when it’s set to cooling mode. Here are some reasons your heat pump may heat when in cooling mode:

Incorrectly Set Thermostat

The thermostat should be set according to the season and comfort level. In cooling mode, the thermostat should be set lower than the temperature inside your home. If it’s set higher than that, it won’t turn on because it won’t detect a need for cooling.

Ensure your service technician double-checks your thermostat settings before trying any other troubleshooting steps. They may notice the settings are incorrect and can reset them for you.

Refrigerant Leak

Heat pumps rely on refrigerant to transfer heat in and out of your home. A leak in the refrigerant line can cause warm air to blow through your vents. Contact experts to locate and fix the leak and to perform other necessary AC repairs.

Clogged Air Filter

Clogged air filters hinder airflow through the system, causing it to run inefficiently. As a result, your heat pump may produce warm instead of cool air when it’s in cooling mode. Regular maintenance and filter changes can help keep your system running efficiently. As a result, you’ll avoid higher than necessary cooling bills.

Dirty Evaporator Coils

Heat pumps pull heat from inside your house and transfer it outside. Over time, dirt and dust accumulate on the evaporator coils, which restricts airflow. A service technician will be able to clean the coils, restoring efficient operation.
