Why Is Your Heat Pump Heating in Cooling Mode?

When the temperatures are soaring outside, nothing feels more satisfying than coming home to a cool indoor environment. However, sometimes your heat pump may not blow the cold air you need due to various issues. Here are reasons your heat pump in Miramar, FL, is blowing hot air in cooling mode:
Your Reversing Valve Is Faulty
A reversing valve is the heat pump component that enables your system to conduct both cooling and heating functions. Being able to cool and heat your home is what makes a heat pump stand out from other HVAC systems.
When it’s hot outside, the reversing valve allows the refrigerant to flow from the indoor coil to the outdoor coil to dispose of the excessive heat in your house. When the temperatures dip during winter, the component makes the refrigerant move heat from the outdoor coil to the indoor coil.
When this component develops problems, it cannot alter the direction of the refrigerant flow. Consequently, your system continues to bring in more heat from outside instead of transferring the heat out of your home. A service technician can repair or replace a malfunctioning reversing valve.
Your Air Filter Is Dirty
Your air filter cannot trap contaminants forever. At some point, you’ll need to change it. If you don’t replace it, pollutants accumulate on it and restrict airflow.
Your system only cools the air that it draws from your living space. A clogged air filter restricts the amount of air that enters your heat pump from your living space.
You Have Thermostat Issues
You may have set your thermostat to “HEAT” instead of “COOL,” causing the system to continue bringing in heat from outside. You may have also set your thermostat fan to “ON” instead of “AUTO.” This causes your fan to distribute air even when your heat pump isn’t extracting heat from the air.
