Geothermal Systems
GeoExchange heating and cooling systems (also known as "ground source heat pumps" or "geothermal heat pumps") use the constant temperature of the earth to provide heating comfort in the winter and cooling in the summer. Along with their high level of comfort, they provide the highest levels of efficiency for heating and cooling. In fact, the U.S. Environmental protection Agency performed a study and concluded that GeoExchange systems provided the lowest operating costs and best environmental performance, even when compared to advanced fossil fuel systems. Studies have shown that GeoExchange systems can save homeowners 30 - 70 percent on their heating bills and 20 - 50 percent on their cooling bills, when compared to standard heating and cooling systems. There are now a large number of builders and contractors who have experience with the installation of these systems, along with hundreds of thousands of satisfied homeowners.
