You do and you notice that it doesn’t seem to be working quite right, so you call your local technician at Fulmer Heating & Cooling to come over and check out your HVAC in Irmo, SC.

When they mention that your geothermal heating system needs repairs, you become confused. What is a geothermal system and how would someone even fix it?

Not to worry, because we have the answers for you that will get you acquainted with this fantastic heating system. Even better, we can get you connected with a professional technician who will provide efficient maintenance and care for your geothermal system for years to come.

What Is a Geothermal System?

A geothermal systems is a ground-source heat pump (versus air-source heat pump) that uses the temperature of the earth to help provide warm and cool air to a home. Even in the coldest of weather conditions, the temperatures within the earth remain relatively moderate. By using the earth as a heat source, geothermal heat pumps can cut back on a home’s energy use by about 65% compared to a normal HVAC system.

What Do Repairs for This System Entail?

A geothermal heat pump has two main parts to it that can require repairs: its indoor unit, and its ground loop.

The indoor heat pump can develop issues such as loose or broken parts (such as a blower fan), an anti-freeze leak, or a problem with the compressor.

In contrast, the underground part of the system can encounter issues such as leaks in the ground loop system or scaling within the ground loop if it is cycling hard water. Thankfully however, the ground loop system for a geothermal unit often has a long lifespan, making it a worthwhile investment.

Whenever you run into an instance when you need repairs for your geothermal heat pump system, you should always call in a professional for assistance.
