Geothermal heating and cooling is extremely energy
efficient and generally provides the lowest utility bills of
any residential system. It taps into the renewable solar
energy from the sun’s rays that’s stored in the ground and
provides savings up to 70% on utility bills.

The secret to a geothermal heat pump’s amazing efficiency
it that, although it operates similarly to a standard heat
pump, it exchanges heat with the ground instead of the
outdoor unit. The temperature just a few feet below the
earth’s surface stays an average 55-70 degrees F year
round.

To capture the heat energy from the ground in the winter
or disperse heat during summer, a long pipe is usually
buried in the ground or placed at the bottom of a pond. An
environmentally friendly antifreeze/water solution, running
through the pipe, acts as the heat transfer medium.

Geothermal systems are extremely quiet, because there’s
no outdoor equipment. The Environmental Protection
Agency has called geothermal heat pumps the most energy-
efficient, environmentally clean and cost-effective heating
and air-conditioning systems available.
