With a geothermal setup, you’ll enjoy year-round energy savings. That’s because your geothermal system can be used to both heat and cool your home, depending on the season.
In the blazing days of summer, a normal air conditioner works by taking in air from the outside, chilling it, and then dispersing it into your home. That process of chilling warm outside air takes a lot of electricity, sending your energy bills through the roof. Instead, a geothermal setup uses a temperature-sensitive liquid to gather the heat of your home, run it through underground pipes, and emerge with a chilled liquid that can then cool the air around it. Because the ground feet down is far cooler than the surface, this chills the air without major electrical work.
The reverse happens in winter. The cold of your home is sent through the system, where it encounters the warmer temperatures beneath the earth. That liquid then is sent back up to keep your home a comfortable temperature.
