Depending on which mode it’s in, your heat pump may either heat or cool your home. However, if you find that warm air comes out when it’s meant to be cooler, it can cause major discomfort for you this summer in Hanahan, SC. Here are a few reasons your heat pump may be heating while in cooling mode:
Issues With the Reversing Valve
The reversing valve controls the direction in which refrigerant flows through your heat pump. When refrigerant evaporates in the indoor coils and condenses in the outdoor coils, the system is in cooling mode. When refrigerant moves in the opposite direction, the system is in heating mode.
Thus, whenever there’s a mismatch between your heat pump’s mode and the temperature of the air it releases into your home, it’s natural to suspect issues with the reversing valve. Ask our NATE-certified technicians to examine the valve, clean it and possibly replace it if it’s faulty. They can inspect it as part of a routine heat pump tuneup.
Low Refrigerant Levels
No matter which mode your heat pump is in, it’ll use refrigerant to move heat into or out of your home. To produce either hot or cold air in the appropriate quantities, the system needs a certain amount of refrigerant. However, if your heat pump ever loses refrigerant while it’s in cooling mode, it may seem like it’s expelling warm air.
Dirty Evaporator Coils
If too much debris covers your heat pump’s evaporator coils, it can prevent the system from absorbing heat from the surrounding air. This can interfere with its ability to produce cold air. Consequently, the system may start pushing out warm air instead.
If, despite being in cooling mode, your heat pump begins heating your Hanahan, SC, home, it can swiftly create an untenable situation. Call Berkeley Heating & Air Conditioning to schedule our HVAC repair services today.
