Geothermal Cooling

The process of cooling a home through geothermal energy may be a little confusing, since the principle of geothermal energy is to extract heat from the ground. But geothermal cooling is a very clever way of cooling a home. In the winter, a geothermal energy system uses water to "collect" heat from the Earth and disperse it through a building. During the summer, the same system uses the same water to extract heat from a building and deposit it back into the Earth.

Saving Space and Reducing Noise

A home or business that needs both heating in winter and cooling in the summer would have to have two separate systems installed. A home or business that uses geothermal energy only has to have one unit for both heating and cooling. The necessity for a loud, outdoor air conditioner that noisily turns on and off throughout the day is eliminated. All the pieces of a geothermal system are under the ground or in the building.

A Clean Cooling System

Traditional air conditioning systems are run with freon, a pollutant that contributes to the depletion of the ozone layer. While a properly functioning air conditioning unit dispenses no freon into the air, old or damaged units release this dangerous substance every time they are used. With geothermal cooling, though, there is very little chance of contaminating the environment.

No environmentally harmful chemicals are used in geothermal cooling systems. Additionally, freon will no longer be manufactured after 2020, in accordance with international treaty. While new, alternative coolants are being researched, geothermal cooling is smart and is available now.
