Don’t Ignore Geothermal Heat Pump Noises

Geothermal heating systems were first invented in the 1850s and didn’t become economically viable until the 1970s, but lately this renewable, sustainable alternative climate control technology is being embraced by more and more people. A geothermal system consists of a heating pump attached to a looped element that runs deep underground and then back into a building.

How Geothermal Heat Pumps Work

The pump can either generate heat by cycling it up from the area below the earth’s surface that remains a constant 50-60 degrees, or it can cool a structure by using the ground element as a heat sink to pump heat away.

Why Go Geothermal?

Geothermal heating systems are desirable for their high energy efficiency. Though it is initially more costly to install this type of system than other, more common heating systems, they quickly pay for themselves in lower energy bills, reduced maintenance costs and in some cases, government incentives.

At last estimation, there were over one million geothermal heating systems installed worldwide. If you own one of them, regular maintenance and repairs are important to keep your home or business comfortable year-round. Getting acquainted with your pump’s behavior, including the noises it may occasionally make, will help you determine when heat pump repair in Myrtle Beach, South Carolina may be necessary.

Common Noises Heard From A Working Heat Pump

There are some sounds that your heat pump will make even when it is operating properly:

Whirring

This noise is caused by the fan moving air over the condensing coils.

Whooshing

In the winter months, the shift of the pump’s reversing valve will make a sound as it maintains defrosting operations.

Clicking

After defrosting, the pump’s compressor will click on.

Buzzing

This noise is most often just the reversing valve’s solenoid coil.

Bad Heat Pump Sounds To Listen For

The following sounds are abnormal and may indicate a problem:

Gurgling

A gurgling noise is indicative of low refrigerant levels.

Clanging

This can be caused by damaged or misaligned fan blades. Upon hearing this sound, you should shut off your pump immediately.

Hissing

This means the reversing valve may not be working properly.

Extremely Loud Clicking

Louder-than-average clicking may indicate problems with the pump’s compressor.

If your heat pump is showing any of these signs, contact a trained professional for heat pump repair in Myrtle Beach, South Carolina.
