Why Your Heat Pump May Not Be Heating Properly

If your heat pump is failing to keep your home warm this winter season, there might be a couple of different reasons why. All of these reasons require professional services in order to be fixed. Still, it doesn’t hurt to know a little bit more about why your heat pump isn’t working the way it’s supposed to. Read on to find out why your heat pump may not be heating properly.

Refrigerant Leak

Your heat pump heats by evaporating refrigerant in the outside unit. This siphons thermal energy from the air surrounding the heat pump. The refrigerant gas is then sent inside to the indoor unit, where it is condensed to vent the collected heat into the home. A leak can develop in the refrigerant line of the system, causing a steady decline in output over time. Once the refrigerant level drops low enough, the system can break down entirely.

Reversing Valve Problems

The reversing valve is a part that sits in the refrigerant line of the heat pump. The valve changes the direction that refrigerant flows through the system, which determines whether or not it is in heating or cooling mode. If a problem occurs in the reversing valve, it can lock the heat pump into one mode. If your heat pump is air conditioning instead of heating, this might be the reason.


Ice can accumulate on the outside of the heat pump in sub-freezing temperatures. If the ice is allowed to cover most of the heat pump coil, it will cut off the system’s access to thermal energy in the surrounding air. The ice will need to be removed to restore the lost output.
