Geothermal heating and cooling is a powerful way to take advantage of an overlooked natural resource: the heat underneath your home! While air temperatures fluctuate severely year-round, the temperature of the ground beneath your house remains fairly constant—even when it’s freezing above ground.
Geothermal systems take advantage of this natural phenomenon by circulating heat between your home and the ground. In winter, the system works by taking warmth from the ground and circulating it through your home, similar to a heat pump. In the summer, the system reverses—your geothermal system takes heat from your home and moves it underground, where it stays cooler. The cooler refrigerant (the fluid that allows for heat transfer) then circulates through your home and allows cool air to blow.
