What Is Geothermal Heating and Cooling and How Does It Work?

Geothermal heating and cooling is one of the most energy-efficient ways to keep your home comfortable year-round. Unlike traditional HVAC systems that rely on outdoor air temperatures, geothermal systems use the stable temperature of the earth to heat and cool your home.
How Geothermal Systems Work
A geothermal system consists of three main components:
- Ground Loop System – Pipes buried underground that circulate a water-based solution
- Heat Pump – Transfers heat between the ground and your home
- Distribution System – Delivers heated or cooled air throughout the building
In winter, heat is drawn from the ground and transferred indoors. In summer, excess heat is pulled from your home and released into the earth.
Why Homeowners Choose Geothermal
- Lower monthly energy bills
- Consistent indoor comfort
- Quiet operation
- Long system lifespan
- Reduced environmental impact
Geothermal systems may have a higher upfront cost, but the long-term savings and efficiency often make them a smart investment.
