Benefits of Geothermal

Instead of burning fuel or relying on electricity, geothermal climate control systems use the energy that is already underneath your building.  This means that once your geothermal system is set up, you can heat and cool your building using FREE energy.

How Geothermal Works

• The ground absorbs and holds nearly half of the solar energy that reaches the earth. Your geothermal system will keep your building warm by extracting this energy and distributing it wherever you need it to be.
• Your geothermal system can create a cool environment by extracting the heat energy from your building and returning it to the ground.
