Homes in Watkinsville, GA, rely on traditional HVAC equipment like furnaces and air conditioners for heating and cooling. By contrast, a geothermal system is a single system that uses the temperature of the earth to control the climate in your home. Learn more about geothermal HVAC systems and how they work below.

What Is a Geothermal HVAC System?

Geothermal HVAC systems consist of two parts. An underground loop with a heat-transferring liquid pulls heat from the earth for heating or disperses it into the ground for cooling. An indoor heat pump then transfers heat from the loop into your home.

How Does Geothermal Work?

Geothermal HVAC systems use the near-constant temperature of the earth. Even on the coldest days, the underground temperature in Watkinsville, GA, is around 65 degrees Fahrenheit. The ground warmed by the sun thus becomes a heat source in the winter and a heat sink in the summer.

Installing a Geothermal System

The most expensive part of the geothermal system is the installation. Inside your home, there is minimal work. The heat pump unit is relatively easy to install, and it can push warm or cool air through your existing ductwork.

The outdoor work is more challenging. The most common design is a horizontal loop, which sits in trenches that are 3 to 6 feet underground. On a smaller lawn, the installer may use a deeper, vertical loop to save space.

Benefits of a Geothermal System

Installing a geothermal HVAC system in your Watkinsville, GA, home has several benefits. These systems are extremely efficient. Although the initial installation is more expensive than traditional HVAC systems, the cost of operation is much lower.

A geothermal system is a clean energy system. This system runs on electricity and the natural heat of the earth, so during the heating season, you will not burn fossil fuels to warm your home. The same goes for the cooling season.

In addition, geothermal HVAC systems are durable. Because they are not exposed to the elements, the underground loop can last up to 50 years. Manufacturers expect the indoor equipment to last 20 years with proper care.
