Common Problems That Can Affect Your Heat Pump

Heat pumps have the occasional problem, just like any other climate control system. Since many of these problems are progressive, it is a good idea to keep an eye out for symptoms so that you can have them fixed as soon as possible. With that in mind, let’s take a look at a few of the more common heat pump problems and the symptoms that they present.

Unit Is Stuck in One Mode

Heat pumps are able to reverse the flow of refrigerant through their systems, which allows them to act as both heating and air conditioning systems as needed. This is part of what makes them so popular. However, it can also cause problems. If your heat pump is stuck in one mode, it means that the reversing valve is malfunctioning. If the reversing valve is stuck for any reason, it causes the heat pump to become stuck in one mode.

Loss of Output

If your heat pump stops blowing warm or cool air, there are a number of possible reasons for it. The first possibility is that you have a leak in your refrigerant line. The refrigerant in your heat pump is what allows it to siphon thermal energy from one place and vent it to another. Without refrigerant, your heat pump is little more than a complicated fan. So if a leak develops in the refrigerant line it could drain your system of the fluid it needs to work. Another possibility is that your evaporator coil is frozen over, which happens when the air flow is cut off or the defrost cycle operates. This prevents the coil from siphoning heat properly and causes a drop in output.
