What is Geothermal HVAC?

Geothermal HVAC (Heating, Ventilation, and Air Conditioning) systems utilize the stable temperatures beneath the Earth’s surface to regulate the temperature inside your home. Unlike traditional air-source systems that rely on fluctuating outdoor air temperatures, geothermal systems tap into the relatively constant temperatures found a few feet underground.

How Does It Work?

The core principle behind geothermal HVAC is pretty straightforward. By circulating a water-based solution through a series of pipes buried in your yard (commonly known as ground loops), the system can absorb heat from the ground or disperse heat into it, depending on whether you need heating or cooling. Think of it as borrowing the Earth’s natural energy to keep your home comfortable.

The Components

To better understand how geothermal HVAC systems operate, let’s break down the essential components:

Component	Function
Ground Loops	These pipes are buried underground and serve as the heat exchanger.
