When you have a heat pump installed, you expect it to perform two different jobs for you: send out warm air during cold weather, and send out cool air during hot weather. This dual function of heat pumps makes them popular options for home comfort, especially in Georgia where their powerful cooling mode makes them as effective as any standalone air conditioner.
But when a heat pump fails to live up to one part of its job—blowing out only cold air when you need warm air—you must call for repairs as soon as possible. Don’t wait and simply hope the heat pump will “warm up” eventually; they don’t work that way, and if a unit gets stuck in one mode, it likely means a malfunction that requires professional repairs.
When you need your heat pump in Atlanta, GA restored to full function, call Air Conditioning Experts, Inc. We have 24-hour emergency service for your convenience and comfort.
Why a Heat Pump May Blow Only Cold Air
A heat pump stuck in cooling mode probably has a failed reversing valve. This component serves to change the direction of the flow of refrigerant through the unit; when the refrigerant changes direction, the heat pump switches from heating to cooling mode or vice versa. If the reversing valve malfunctions, it will trap the heat pump in one mode or the other. A heat pump repair technician must open the cabinet, remove the broken reversing valve, and replace it with the correct unit.
Thermostat troubles constitute another possibility for the heat pump remaining in cooling mode. You should always check the thermostat’s setting when you encounter trouble regulating the temperature from a heat pump, since incorrect setting or programming can cause the system to switch into the wrong mode. A malfunctioning thermostat that loses its connection to the heat pump will also cause it to become stuck in one mode. Professionals can look over the thermostat to see if a malfunction has caused the problem.
Loss of refrigerant due to leaks can also impair the heat pump’s ability to provide warm air. Check the outdoor cabinet to see if you can spot ice developing over the coil. The presence of ice means a loss of refrigerant, and the outdoor coils will struggle to absorb the heat that the indoor coils will release. Scraping the ice off will do no good; you’ll need a technician to find and seal the leak, then recharge the refrigerant to its proper level.
