Heat pumps in Daniel Island, SC, continue growing in popularity because they’re both cost-effective and energy-efficient solutions for heating and cooling homes. Depending on the season, they should provide warm and cool air, but sometimes things go wrong. Read on to understand why a heat pump sometimes heats when in cooling mode.

Thermostat Issues

If your heat pump’s thermostat isn’t programmed correctly, you’ll experience issues with heating even when in cooling mode. Adjust the settings, as this will help to ensure the heat pump is in cooling mode. Ensure the reversing valve is set to cooling mode, too.

Refrigerant Loss

Heat pumps distribute heat to different places with the help of a refrigerant; it extracts heat from a room in the summer, and in the winter, it extracts radiant energy from the outside air and delivers it inside the rooms. A leak in the refrigerant line alters the performance of the heat pump, which can make it heat in cooling mode even if your thermostat is set correctly.

Dirty Heat Pump Coil

The heat pump’s outdoor unit can collect dirt. Too much accumulated dirt affects the heat pump’s performance, reducing its ability to heat or cool when needed.

In some cases, this may lead to the heat pump heating when in cooling mode. Ensure that the outdoor unit is well-cleaned. Avoid high water pressure and use a light brush to scrub off stubborn spots.

Clogged Air Filter

Air filters trap dirt when air passes through them. Allowing this debris to build up blocks airflow, making it challenging for the heat pump to operate effectively. Change your air filters once every one to three months to keep your system running smoothly.
