Get the most out of your heat pump with an efficient and reliable heat pump reversing valve. Find out why this essential part is necessary for your heating and cooling system and how to maintain it for optimal performance.

How Does a Heat Pump Work?

Heat pump systems provide efficient heating and cooling by redirecting the refrigerant flow like how an AC works in summer.

How a Reversing Valve on a Heat Pump Works!

The reversing valve allows your heat pump to switch between heating and cooling by using a reversing valve that redirects the refrigerant flow.

Heat Pump Reversing Valve

A reversing valve is made up of three parts. The cylindrical component that directs the flow and the suction and discharge lines that allow for the movement of refrigerant.


Electromagnetic Solenoid

It also has a solenoid, which tell the reversing valve which ports it should use to direct the refrigerant between the indoor and outdoor coils based on whether its heating or cooling.

How the Coils Operate in Winter

The indoor coil becomes the condenser coil in heating mode, which acts as a heat rejector and the outdoor coil is the heat absorber.

How the Coils Operate in Summer

This reverses in summer and your heat pump acts exactly like an AC. It takes heat from inside your home and dumps it outside.
