The ground absorbs nearly half of the sun’s energy that reaches the earth. A geothermal HVAC system harnesses that free, renewable energy to provide an economical, eco-friendly way to heat and cool your home. With locations in Exton, PA; King of Prussia, PA; and Wilmington, DE and serving all the surrounding areas; ServiceMark can install and service a geothermal heating system on any new or existing HVAC. Geothermal systems capitalize on the solar energy stored year-round just beneath the earth’s surface. This free geothermal energy is an unlimited, renewable resource. The ground space surrounding a typical suburban home contains 10 times more energy than a home requires over an entire heating season. This resource is constantly being replenished by the sun, the surrounding earth, and the heat that’s rejected while the geothermal system is cooling in the summer.
