Repairs a Geothermal Heating System May Need

Friday, February 20th, 2015

Geothermal systems are built to last – after all, they do have an average lifespan of up to 50 years – but that doesn’t mean they won’t ever have repair issues. There can be some concern over geothermal repairs because parts of the system are so different from more traditional heating systems, but when you hire trained experts, like the ones from Atlantic Refrigeration, you can rest assured that your geothermal heating repairs in Dover, DE, are in good hands.

Types of Repairs

Here are some of the repairs that can develop with a geothermal system:

Issues with the Heat Pump

Geothermal systems use a heat pump to transfer the heat back and forth. The heat pumps will either be water-source or ground-source, depending on the type of geothermal system you’ve installed. One of the most common problems with heat pumps is compressor issues. The compressor pressurizes the anti-freeze in the system, so problems with the compressor can create heating issues. Other issues that can develop are problems with the coils and issues with the condenser.


There are a number of minerals in water, and sometimes these minerals can form a build-up in piping called “scale”. The ground loop of geothermal systems, and even the heat pump, can develop scale, which, if significant enough, can restrict the flow of the anti-freeze in the system. An acid flush performed by a trained professional can remove the scale build-up easily.

Ground Loop Leak

The ground loop developing a leak is one of the top concerns about geothermal systems, but it doesn’t have to be. First, leaks rarely develop and second, technicians use a specific process to pinpoint the leak location before digging. The process involves injecting non-toxic dye into the ground loop and waiting for the dye to bubble to the ground’s surface; the location of the dye on the ground’s surface indicates where the leak has developed. Once the dye appears, digging can begin and the leak can be repaired.

Geothermal systems are the most energy efficient systems available and their long lifespan can mean years of comfortable, very environmentally-friendly heating and cooling.
