Geothermal heat pumps are quite popular among residents on Shaw AFB, SC. However, they can develop a few minor issues over time. Some of the most common problems include water leaks, corrosion, uneven heating or cooling and contaminated water.

1. Water Leaks

A geothermal heat pump uses a cooling chemical called refrigerant to do its job, but this chemical can sometimes spill out if everything isn’t sealed. In the same way that a traditional heat pump can spring a leak, a geothermal unit can sometimes leak refrigerant into your yard. Fortunately, leaks from a geothermal heat pump are usually easy to fix.

2. Corroded Metal

Geothermal heat pumps have long life spans, but some parts can corrode over time. The heat exchange coils are especially vulnerable, so it’s important to get a qualified technician to check them regularly. As with most HVAC problems, it’s best to fix corrosion issues before they become more serious.

3. Uneven Heating or Cooling

This isn’t so much a problem with the heat pump as it is with your air ducts, but it can still be a nuisance to deal with. When your air ducts are clean, they can spread out the thermal energy from your geothermal system evenly across your home. If you find that your basement, for example, is much hotter or colder than your living room, check your ducts for dirt or blockages.

4. Contaminated Water

Geothermal heat pumps work on a closed-loop piping system, so any contamination that gets into the system will tend to stay there and keep getting recycled. If your system uses water from an external source, it’s worthwhile to install an extra filter or two just to be on the safe side.
