Heat Pumps are becoming increasingly popular for a good reason. Nothing beats the convenience of having an appliance that works to cool your home in the summers and warm it in the winters. Heat Pumps with their dual function also help you save on the costs of buying, maintaining and repair costs of other appliances.  The fact that heat pumps move heat instead of generating it explains why they are so energy efficient.

However, like all good appliances they also require maintenance. As an owner you can look out for some signs that may mean that your friend is having trouble keeping up with the weather. Even if you miss on some of these, with summer approaching it can be a good idea to have it checked out by a professional.

How to Detect

Here are some common signs to look out for when your heat pump starts acting up:

Sudden Lack of Heat

When this happens, the first thing to do is to check the thermostat.

It could be something as simple as someone turning it off and forgetting about it. If your appliance had a thermostat replaces recently then it may not have been the right one. In this case it might be time to call in someone because the wrong thermostat can damage the circuit of your appliance leading to more problems.

Not Enough Heat

If the heat pump performs less efficiently as before then it may be time to get the coils replaced, or you might need to get the filter cleaned out. Dirty parts of the appliance such as fans can prevent airflow in the appliance leading to a decrease in performance. Outdoor parts of the appliance may also need to be cleaned out and any debris removed for optimum functioning.

Freezing Up

In cold weather the heat pump can ice up and this is nothing to worry about because this can easily be the defrost cycle kicking in to melt the ice. IF this seems to go on forever, then you can turn the appliance off to melt it. If this happens more than once call an HVAC professional.


Squealing or grinding is not good. You can take a look and make sure the cover panels are screwed on tight. If they are tight then the noise may be coming from ductwork that has come lose or parts of the air handler. If the sound has been there from day one, a heating repair contractor can install insulation of some sort to prevent the sound.
