Homeowners often prefer heat pumps over other HVAC systems due to their ability to heat and cool their homes. However, for a variety of reasons, your heat pump may start warming your house when you need it to blow cool air, leaving you hot and frustrated. Below, we will explore why your heat pump system in Fortson, GA blows hot air in cooling mode.
The first problem that may cause your heat pump to blow hot air when you need cool air is the most obvious one: you forgot to set the thermostat to “Cool.” As a result, the heat pump continues to bring in more heat from outside.
You may have also used the “On” fan setting instead of “Auto.” When you use the “On” setting, the thermostat prompts the fan to continue running continuously, even after the cooling cycle has ended. As a result, the fan may circulate warm air throughout your house.
Consider using the “Auto” fan setting. When you enable this setting, your fan will only run when a cooling cycle is in progress, thus distributing cold air evenly throughout your house.
A Faulty Reversing Valve
A reversing valve is a component that enables a heat pump to both heat and cool your home. The heat pump achieves this objective by altering the direction of the refrigerant flow.
During the cold months, the valve prompts the fluid to bring in heat from the outdoor unit to the indoor unit. When the warm months set in and you change your thermostat to its cooling mode, the component makes the refrigerant move heat from the indoor unit to the outdoor unit.
If the valve malfunctions, it does not change the direction of refrigerant flow; thus, the fluid continues to bring in heat from outside. A technician can easily repair a faulty reversing valve.
A Clogged Air Filter
A blocked air filter creates a barrier that prevents your heat pump from drawing in air from your house. The system can only cool as much air as it draws in. Therefore, if it does not draw sufficient air, your house will remain warm, hence why you should make sure your filter is clean and clear.
