This space conditioning systems can reduce your utility bill up to 70% and the systems typically pay for themselves within just a few years. Heat pumps move heat energy from the ground to your structure and back. Your refrigerator works using the same scientific principle. By using the refrigeration process, geothermal heat pumps remove heat energy stored in the earth and/or the earth's groundwater and transfer it to the home.
