Geothermal Heating & Cooling Systems in Madison, WI

Geothermal is an energy-efficient, cost effective space conditioning system that taps into the earth to capture its renewable energy.  The earth absorbs the sun’s energy that reaches it, storing that energy in the ground. A geothermal system extracts that energy for heating during winter. For cooling, the system removes heat from the home and dumps it into the cooler earth. This transferring of heat is accomplished using a series of pipes buried deep in the ground.  Not only is a geothermal system a renewal energy source making it highly energy-efficient, it requires no outdoor unit and is quiet, reliable and durable.
