Although heat pumps provide a number of excellent advantages as home comfort systems, such as energy-efficient performance and low emissions, the #1 benefit they offer is that they operate as both air conditioners and heaters. Two indoor comfort problems solved with one unit!
However, a heat pump can malfunction and become stuck in one mode, either blowing out heat when you want a cooled-down home, or blowing out chilled air when you want to warm up. When this happens, you lose one of the reasons you opted for heat pump installation in the first place. However, professionals can easily solve this problem and restore your heat pump to full power.

Why a heat pump won’t switch modes
The most common reason for a heat pump staying either in cooling or heating mode is a malfunction with the reversing valve. This valve is a crucial component that makes a heat pump different from a standard air conditioner: it sits on the refrigerant line and controls the direction the refrigerant flows through the unit. When the refrigerant changes direction, the heat pump switches from heating to cooling or vice versa. If the reversing valve breaks, the heat pump will remain in one mode (which one depends on the manufacturer’s settings). This is a simple repair for a professional: it only requires exchanging the broken reversing valve for a new one.
Another possibility for a heat pump that will only do half of its job is not a problem inside the heat pump, but in the thermostat. The electrical connections in the thermostat are responsible for signaling the heat pump to move from one mode to the other and to turn its blower on or off. If the thermostat loses that connection, the heat pump could remain fixed in one mode. Heating technician can trace down the source and repair the thermostat.
Heat pumps need trained repairs
Although you may feel tempted to open up the cabinet of your heat pump and tinker with the reversing valve, or unscrew the plate of your thermostat and fiddle with the wires, you are much more likely to cause further damage—unless you are a trained HVAC technician with the right equipment. It’s easy to find people who can do the work: call Air Conditioning Experts, Inc., any time of day or night, and we can take care of your cooling and heating repair in Atlanta, GA.
