Why Is My Heat Pump Blowing Cold Air?

Heat pumps are popular primarily for their ability to switch between heating and air conditioning functions. If the heat pump becomes stuck in one mode, though, it can quickly start to seem like more of a hindrance. If your heat pump can’t seem to switch into heating mode, read on to find out why.

The Reversing Valve

The reversing valve is the part of the heat pump responsible for switching it back and forth between two modes. The valve sits in the refrigerant line, and contains a slide that moves back and forth between two positions. Depending on the position the slide is in, the refrigerant in the system will flow one way or the other. This determines whether the heat pump heats or cools the home. The slide is moved back and forth by the solenoid, which is an electromagnet that’s part of the valve. If your heat pump is stuck in one mode, it’s almost certainly a problem with the reversing valve.

Problems

There are two possible issues that can afflict the reversing valve. The first issue is that the slide simply becomes stuck in the valve. If the slide can’t move, it can’t change the flow of refrigerant to make the system switch modes. You’ll need to have a professional open up the valve and reset the slide if this is the problem.

The second possibility is that your solenoid has lost its charge, making it unable to move the slide. Unfortunately, the only thing that can be done in this case is to replace the solenoid. Call a professional if your heat pump can’t seem to switch modes.
