Why Your Heat Pump Blows Warm Air in Cooling Mode in Lakeland, GA
You set your heat pump to cooling mode to prepare for the summer in Lakeland, GA. But during your initial run, it started blowing warm air. If you checked the thermostat for the proper settings, the issue must lie with the heat pump itself. Here are the most common reasons for heat pumps blowing warm air in cooling mode:
Bad Reversing Valve
The reversing valve switches the direction of refrigerant through the heat pump, which determines if the system heats or cools. However, if this device is stuck or has developed a bad solenoid coil, it may never have switched to cooling mode.
Other times, the heat pump may technically be in cooling mode, but it blows warm air on account of some obstruction to airflow. The number one culprit in this regard is a clogged air filter. You may also have furniture or a rug blocking the registers, leading to some rooms remaining hot.
The evaporator coil in the indoor unit absorbs heat from your home when in cooling mode, and the condenser coil outside releases it. Both coils must stay clean or else you won’t get cool air, so check these components or leave the job to a service technician during a maintenance visit.
Lastly, you may experience warm air if your refrigerant charge has dipped below an acceptable level. Usually, this occurs because of a leak in the refrigerant line.
