When your heat pump is in cooling mode, it should generate and expel cold air. If it begins doing the opposite, it can create confusion and discomfort in your Wendell, NC, home. To help you handle these difficulties, we’ll discuss a few reasons your heat pump may have started blowing hot air while in cooling mode.
Refrigerant Leak
When it’s in cooling mode, your heat pump should absorb the warm air in your home and pass it over its indoor evaporator coils. The refrigerant that sits in the coils should extract the heat from the air and move into your system’s compressor, which should heat and pressurize it until it reaches a condensable state. Finally, the refrigerant should travel to the system’s outdoor condenser coils and condense and release its heat, thus setting the stage for the cycle to repeat itself.
However, if there isn’t enough refrigerant circulating through your heat pump, this process either won’t occur or will produce weak results. Consequently, your system may end up expelling hot air instead of cold air. You should trust only trained HVAC service technicians to seal refrigerant leaks and refill your system.
Faulty Reversing Valve
Depending on whether your heat pump is in heating or cooling mode, refrigerant may move in one direction or another. The reversing valve controls the direction of this flow and should shift position whenever the system switches modes. If the valve malfunctions, it may remain in heating mode while the system is in cooling mode.
Accumulating debris and physical damage can cause valve malfunctions. During an annual maintenance checkup, service technicians can either clean your valve or replace it.
Malfunctioning Compressor
If your heat pump’s compressor fails to work, the heat transfer process won’t occur at all. You must make sure that this crucial part remains functional.
