Geothermal heating and cooling, also known as GeoExchange, is a heating and cooling technology that surpasses most traditional and alternative systems by simply moving heat from its source to another area.

In the heating mode, a geothermal or ground-source heat pump extracts energy from the earth—typically using a buried water loop—and moves it indoors. In the summer, the heat pump moves heat from indoors into the relatively cool earth, via the water loop. The result in both seasons is that less energy is needed than with conventional air-to-air heat pumps, natural gas, or oil heating systems. There are two major components to a geothermal system: the heat pump and air-duct portion, and the in-ground water loop well system.

The ground loop may represent an additional approximately 30 percent to 40 percent additional cost compared to a traditional HVAC system…
