Geothermal Systems

Geothermal systems operate more efficiently than standard systems. We service and install Geothermal systems that combine stored earth energy with electric power resulting in saving of up to 70%.

Geothermal Heat Pumps use the constant temperature of the earth as the exchange medium instead of the outside air temperature. This allows the system to reach fairly high efficiencies (300%-600%) on the coldest of winter nights, compared to 175%-250% for air-source heat pumps on cool days. While many parts of the country experience seasonal temperature extremes from scorching heat in the summer to sub-zero cold in the winter a few feet below the earth’s surface the ground remains at a relatively constant temperature. Depending on latitude, ground temperatures range from 45°F to 75°F This ground temperature is warmer than the air above it during the winter and cooler than the air in the summer. The Geothermal Heat Pump takes advantage of this by exchanging heat with the earth through a ground heat exchanger.

Geothermal System Advantages

The biggest benefit of Geothermal Heat Pump Systems is that they use 25%-50% less electricity than conventional heating or cooling systems. According to the EPA, geothermal heat pumps can reduce energy consumption and corresponding emissions up to 44% compared to air-source heat pumps and up to 72% compared to electric resistance heating with standard air-conditioning equipment. Geothermal Systems also improve humidity control by maintaining about 50% relative indoor humidity, making GHPs very effective in humid areas.

Geothermal heat pump systems allow for design flexibility and can be installed in both new and retrofit situations. The systems also provide excellent “zone” space conditioning, allowing different parts of your home to be heated or cooled to different temperatures.

Because they have no outside condensing units like air conditioners, there’s no concern about noise outside the home.
