With temperatures cooling in Covington, LA, you depend on your heat pump to keep your home warm. Unfortunately, some issues lead to your systemp blowing cold air even when it’s in heating mode. If your heat pump is cooling when you need heat, consider these three possible causes.
A Malfunctioning Reversing Valve
During summer, the refrigerant transfers heat from the coil inside to the one in your outdoor unit. When winter comes, the reversing valve changes the direction of the refrigerant flow to make the fluid move heat from outside to the coil inside.
If this component malfunctions, it cannot reverse the refrigerant’s flow. As a result, the fluid continues to move heat from the indoor coil to the outdoor coil instead of the other way around. Request a technician to repair the faulty reversing valve to restore your system’s efficiency.
Low Refrigerant Levels
There are other refrigerant-related problems that lead to heat pumps blowing cool air. If you have a refrigerant leak, resulting in an insufficient amount of refrigerant, it’s not possible for your system to warm the air before pushing it into your home.
Wrong Thermostat Settings
Make sure that your thermostat is set to “AUTO” instead of “ON.” When you set the device to “ON,” the fan runs continuously, even when the heat pump has completed a heating cycle.
This means the fan will distribute unheated air if it runs when your system is not actively working to warm up your indoor air. Consider using the “AUTO” setting, as the setting prompts the fan to run only when the heat pump is heating your indoor air.
Fortunately, a technician can resolve the issues making your heat pump fail to warm your house. Contact us at Three Rivers Services, LLC for outstanding heating services whenever you need a technician to inspect your system.
