Why Heat Pumps in Middletown, MD, Heat in Cooling Mode

If you live in Middletown, MD, you need to prepare your heat pump for the summer months. But let’s say you tested your heat pump already after switching it to cooling mode and the system blew out only warm air. Only malfunctioning heat pumps would heat in cooling mode. Here are some common problems that can cause this to happen:

Stuck Reversing Valve

Situated on top of the refrigerant line, the reversing valve changes the direction of refrigerant flow, which determines whether your heat pump is in heating or cooling mode. This part can become stuck, or the solenoid coil within it can suffer from a defect. If this is the case, the system stays in the same mode it was in the last time you used it.

Backed-Up Airflow

During a maintenance visit, a service technician can easily identify those areas where you’re hindering the circulation of air. But if you’ve neglected to have professional maintenance done, you may be trying to cool your home with a clogged filter or a blocked vent. Such issues will prevent heat from leaving your home.

Dirt on Coils

Even more pertinent, the evaporator and condenser coils will prevent the transfer and removal of heat if dirt and grime cover them. Dirt build-up on the evaporator coil usually follows when you ignore the filter. Consequently, you’ll receive lukewarm air.

Refrigerant Leak

Your heat pump needs a certain charge of refrigerant to effectively transfer heat. A leak in the refrigerant line can certainly cause the air to become hot, and it can also harm your health.
