Your Heat Pump Reversing

The Importance of Your Heat Pump Reversing Valve

Monday, April 18th, 2016 at 11:00 am

Heat pumps are gaining in popularity, both for their energy efficiency and their ability to offer both heating and cooling functions. However, few people are actually aware of how a heat pump works. You don't need to know exactly how a system works in order to use it, of course, but it's a good idea to know about certain parts that may require prompt repairs down the line. Let's take a look at the reversing valve in your heat pump, and how to tell when it's in trouble.

What is a Reversing Valve?

The reversing valve is the part of the heat pump that allows it to act as either a heater or an air conditioner. The part is a 4-way valve that sits in the refrigerant line of the system. Inside the valve, a slide is moved between two positions by an electromagnet called the solenoid. Depending on the position the slide is in, the refrigerant will flow one way or another through the system. This determines which coil evaporates refrigerant and which condenses it, thus determining whether the heat pump heats or cools a home.

Problems Related to the Reversing Valve

If the reversing valve malfunctions in some way, it commonly gets the heat pump stuck in one mode or another. There are a couple of ways this could happen. The slide could get stuck in the valve due to an obstruction of some kind, preventing it from moving to change the flow of refrigerant. It's also possible for the solenoid to lose its charge, making it unable to move the slide. You'll need to have a professional examine the valve for you to tell for certain.
