Common Geothermal Repairs

Geothermal systems are incredibly durable; after all, they have an average lifespan of 25-50 years. As these systems grow in popularity, their uniqueness can make homeowners wonder: what kind of repairs are common with this system? The concern is natural, as the buried ground loop can create images of challenging repair issues. Rest assured that geothermal systems tend to have fewer instances of repairs compared to other more traditional heating systems, and when you do have a need for geothermal repair, you can call the experts at Comfort Flow Heating to meet all your geothermal system repair needs.

Heat Pump Issues

Geothermal systems use heat pumps to facilitate the transfer of heat. During the winter, the heat is moved to your indoors and during the summer the heat is moved to ground or water where the loop resides. Common heat pump issues are anti-freeze leaks, problems with the compressor or condenser and age.


Many geothermal systems use water to help facilitate the transfer of heat. Water contains minerals, and these minerals can create build-up on the inside of the ground loop called scale. Scale is made of mineral deposits that tend to be high in calcium. If there’s enough scale build-up, the flow of the anti-freeze in the ground loop can be restricted. A simple acid flush performed by a professional can clear scale away and restore the flow inside the ground loop.

Issue with the Manifold

The pipes of a ground loop system need a single connection point that carries the fluid into the heat pump that resides in your home; this component is called the manifold. The manifold typically has several valves that correlate to the pipes connecting to it, and sometimes problems can develop with a valve, including scale build-up.

Geothermal systems should always be repaired by those who have experience with the systems because they are not like traditional heating systems, even with the use of heat pumps. The specialists at Comfort Flow Heating have the expertise and training you need for your geothermal system in Eugene, OR, so call us today.
