Is Your Heat Pump Ready To Switch To Cooling Mode?

sun-and-snowflake-animationIt’s been a long, cold winter, and while you may be ready for warmer temperatures, that doesn’t necessarily mean your heat pump is.

Many homeowners appreciate the fact that their heat pump has the ability to both heat and cool their home; however, what they may not realize is that this type of system isn’t always able to change modes so seamlessly. In fact, an inability to switch between heating and cooling mode is one of the more common troubles heat pumps can run into.

In this article, we’ll review some common causes of this malfunction, and what you can do to address it.

Broken Reversing Valve

The reversing valve is what allows your heat pump to change between heating and cooling mode. This valve is controlled by a solenoid, which is in turn activated by an electrical signal from your heat pump’s thermostat. If this valve becomes damaged or malfunctions, it can prevent your heat pump from changing modes.

This can require a larger repair, but if you catch it early enough, it may be something that your HVAC technician can clean or adjust.

Thermostat Issues

If your heat pump is having trouble changing modes, it’s possible that the issue lies with the thermostat. The thermostat is responsible for sending the signal to the solenoid that controls the reversing valve. If there is a problem with the thermostat, this signal may not be sent, which can prevent the heat pump from changing modes. 

Checking the thermostat is a relatively easy task that you can do yourself. First, make sure that the thermostat is set to the correct mode (heating or cooling). If it is, then check to see if the batteries need to be replaced. If neither of these solutions works, then you may need to call a professional to take a look at your thermostat.

Clogged Air Filter

A clogged air filter can also prevent your heat pump from changing modes. If the air filter is too dirty, it can restrict airflow to the point where the heat pump isn’t able to function properly. This can cause a number of different problems, one of which is an inability to change modes.

If you suspect that your heat pump’s air filter is the culprit, the best course of action is to replace it. This is a relatively easy task that you can do yourself, and it only takes a few minutes.

Ultimately, if you’re in doubt about your heat pump’s ability to change modes in preparation for this warmer season, the best course of action is to call a professional. They will be able to diagnose the problem and recommend the best course of action.
