Geothermal Heating & Cooling in South Carolina

Heating and air conditioning systems have the one task to keep us warm in winter and cool in summer. For winter heating, this has been accomplished since ages by burning fossil and other fuels such as wood, coal, gas and electricty to heat our houses. In South Carolina for summer cooling, electricity powered air conditioners are used to pump heat from the inside to the outside, the heat is disposed of in the surrounding air. Pressure by environmental and economical concerns, smarter solutions were developed using the ground or earth as provider for thermal energy, whether for heating and for cooling. Geothermal heating and cooling is the answer.

Thermal energy is available in abundance and is free! Consequently, only the energy to move the energy from or to the energy source Earth needs to be purchased.

The temperature level of the earth is more favorable than the temperature of the surrounding air, which is hotter in summer, when we cool and colder in winter when needed for heating. The earth has a constant temperatur eof about 40 - 80 degree Fahrenheit depending on location and depth below the surface .

SC Geothermal Testimonials

Nancy Briggs from Sumter says:
We intalled our geothermal system in December 2008. Our house is circa 1930 -not built as \"tight\" as new homes. Our electric bills began dropping dramatically from the 1st month. And, the gas hot water bill dropped, too. The indoor termperature remains constant no matter the outdoor temperature. No cold drafts. No outdoor noise. We couldn\'t be more pleased!
