                                                          Geo-thermal heat pumps use the constant ground temperature, which is about 52 degrees Fahrenheit, to heat and cool your living space. Piping coils are buried 5 feet underground in your yard, and freon or  water is circulated through the pipes and then through the heating system in your home or business.
