A geothermal heat pump is the most efficient heating and cooling system available today, using the renewable resources of the earth for heat transfer. The stable temperatures of the earth make it possible for the energy exchange to occur in geothermal systems, keeping you comfortable year-round. In the winter, heat is absorbed from the ground and transferred to the heat pump where it is distributed by the air handler. In summer, hot air in the home is extracted and transferred to the cooler ground. Geothermal systems require only a small amount of electricity to exchange heat with the earth, saving you money on your monthly utility bills. To learn more, visit www.climatemaster.com
