Ground geo-thermal systems balance the internal temperature of a structure with the temperature below the Earth’s surface through the use of heat exchange technology. This process requires considerably less energy than furnace or air conditioning units, and can improve air quality. Ground geo-thermal systems help moderate the internal temperature of your structure, alleviating your heating and air conditioning systems’ workload, and can significantly reduce your energy usage and costs.
