Your heat pump is an essential piece of HVAC equipment for heating and cooling your Hendersonville, TN home. However, sometimes when you switch to cooling mode, all you feel is hot air. Here are some reasons why this is happening.
Thermostat Problems
The issue with hot air blowing from your heat pump is often as simple as a malfunctioning or incorrectly programmed thermostat. Whether you have a broken thermostat or someone accidentally toggled the switch, this is a fairly straightforward fix. Your comfort care specialist will check the thermostat and replace it if necessary.
Broken Reversing Valve
The reversing valve on your heat pump allows the equipment to function as a heating or cooling system depending on how it directs the flow of the refrigerant. The system won’t function properly when you have a broken reversing valve. You need to have one of our AC service professionals replace the valve.
Dirty Coils
Both outdoor and indoor heat pump coils accumulate dirt, dust and debris that require cleaning the equipment to remove those substances and ensure the appliance works as intended to cool the house. Schedule annual or seasonal HVAC maintenance to take care of the buildup of dirt and debris on the coils.
Lack of Refrigerant
Refrigerant is necessary for your heat pump to blow cold air. Insufficient refrigerant is often due to a leak in its supply line. In this case, the refrigerant line requires repair as well as additional refrigerant to remedy the problem.
If you’re experiencing continuous hot air blowing from your Hendersonville, TN heat pump while it’s in cooling mode, it’s time to contact your HVAC service provider. Give Derryberry’s Heat & Air a call to schedule HVAC maintenance or to repair the system.
