What is Geothermal Heating and Cooling?   This marvelous technology relies primarily on the Earth's natural thermal energy to heat and cool a house or multi-family dwelling. The only additional energy required is a small amount of electricity to concentrate what Mother Nature provides and circulate high-quality heating and cooling throughout the home. Geothermal heating and cooling is very cost effective because it uses energy so efficiently. This makes it very environmentally friendly, too – and that's why it's endorsed by federal agencies like the Environmental Protection Agency and the Department of Energy.   HOW DOES IT WORK?
