Why Your Heat Pump Is Stuck in Cooling Mode

Answer as fast as you can: What is the great advantage of having a heat pump?

Did you respond “It works as both a heater and an air conditioner?” You most likely did, since the reason most people opt to have a heat pump installed in their home is that is takes care of two installations at once and simplifies their lives.

So if the heat pump in your home loses one of its two modes and starts blowing out cold air when you want warm air, you need to have professionals come to your home and find out what needs repair.

There are a few reasons that a heat pump might become stuck in cooling mode (or heating mode, as is sometimes the case). Most of them will need repairs from trained technicians. Call Boehmer Heating & Cooling when you need heating repair in Pittsburgh, PA for your malfunctioning heat pump. We have live operators standing by 24/7 for emergency service.

Reasons a Heat Pump Won’t Switch Modes

The most common cause for a heat pump to remain fixed in cooling mode is a broken reversing valve. This component sits along the refrigerant line and is responsible for changing the direction that refrigerant moves through the pump. Essentially, the reversing valve is what makes a heat pump different from an air conditioner, and if it breaks down, it will leave you with an air conditioner. (As mentioned above, it could also leave you with it heater. It depends on how the manufacturer set the reversing valve’s “relaxed” state, the one where it doesn’t receive an electric charge.)

Fortunately, a broken reversing valve is a simple fix for a technician. He or she will swap out the old valve for a new one. New reversing valves are a basic part of most technician’s vans when attending to heat pump problems.

Another reason for a heat pump staying in one mode is a thermostat issue. A faulty wiring connection can cause thermostat to lose its connection to the system that signals for it to begin heating. This is a simple wiring fix for a technician, but don’t attempt to pull the unit off the wall and fiddle with the wires yourself; you will probably only cause the problem to get worse.

If the air that comes from the vents isn’t cold but instead feels room temperature, the trouble may be a loss of refrigerant. Check to see if icing has started over the outdoor coils, then call for repairs.

Heat pumps are among the more complex comfort devices available for homes today, and they require a precise balance of components to work properly. Do not trust any repairs to amateurs, and do not go the “do-it-yourself” route. Look to the Pittsburgh, PA heating repair professionals at Boehmer Heating & Cooling.
