The #1 Resource for Geothermal Heating and Cooling in Illinois

About Geo

Your own backyard has the potential to be an energy source for heating and cooling comfort. Outdoor air temperatures fluctuate throughout the year with the changing seasons. In contrast, ground temperatures about four to six feet below the Earth’s surface remain relatively moderate and constant all year.

“Owning a geothermal System has been great.”

I've owned a geothermal system for over 7 years now. It has kept my power bills low while keeping my family comfortable. It operates quietly and efficiently all year round. Owning a geothermal system has been a great experience.

Efficient

A single piece of equipment heats and cools your home, while providing some or all of your home’s hot water as well. Geothermal systems can save you 30 percent to 70 percent on your monthly utility bills.

Renewable

 A geothermal system circulates a water-based solution through a buried loop system to take advantage of the Earth’s constant temperatures.

Incentives

The federal government offers tax credits for homeowners who install a geothermal system on their property.
