Why Your Heat Pump Output is Low

If you’re using a heat pump to keep cool this summer, and the output is low, there could be a couple of different reasons why. All of these reasons, though, will require professional repair services. You may not be able to repair these problems yourself, but it still may help you to know how they work. Let’s take a look at some of those problems now.


Refrigerant is the core of your heat pump. The system evaporates refrigerant in one unit to absorb heat, then condenses it in the other unit to release the collected heat. This is how the heat pump cools your home, by recycling refrigerant back and forth between the two units. The initial charge of refrigerant a heat pump gets the first time it is installed should be enough to last for its entire life. The only time the system needs more refrigerant is if a leak develops in the line. This will cause a drop in output, and eventually a full system breakdown. Call for repairs if you notice liquid dripping from your heat pump.

Air Handler Issues

The air handler is the part of the system responsible for circulating air throughout the home during operation. If the air handler is malfunctioning, it will not be able to circulate the air in your ducts and your heat pump will have no way of distributing cool air. If you aren’t getting any airflow from your heat pump at all, it may indicate that you have an air handler problem.

Reversing Valve

If your heat pump is stuck in heating mode, instead of cooling mode, you probably have a reversing valve issue. This is the valve that allows the system to switch between modes. If the valve is broken, the heat pump won’t be able to switch properly.
