It’s that time of year in Martinez, GA when you want to switch your heat pump to AC mode to cool your home. Sometimes a heat pump blows hot air when you don’t want it to. Let’s explore some reasons why your system seems stuck in heating mode.
Thermostat Isn’t on Cool Mode
While this might seem like an obvious cause for the heat pump to stay in heating mode, it is common for a thermostat to be set to heat or fan-only mode. This usually happens by mistake when someone has accidentally toggled the switch and turned off the cooling option. Simply reset or reprogram the thermostat.
Malfunctioning Thermostat
A malfunctioning thermostat can prevent your system from switching to cooling mode. If your thermostat won’t switch from heating to cooling mode, have our comfort care specialist check the thermostat during seasonal maintenance and replace it.
Faulty Control Board
The control board in an HVAC system manages its operation. When the control board becomes faulty, it might not signal the system to switch from heating to cooling. One of our professionals can diagnose and repair this issue.
Low Refrigerant
Refrigerant is necessary for your heat pump to blow cold air. Lack of sufficient refrigerant can cause it to stay stuck in heating mode. A licensed HVAC professional can add more refrigerant to remedy the problem.
Failed Reversing Valve
An important component of your heat pump system is the reversing valve that allows the equipment to toggle from heating to cooling mode by directing the flow of the refrigerant. The HVAC system won’t function in AC mode if you have a broken reversing valve. This valve requires replacement by a trained professional.
