Affordable Energy Technologies is the mid-west distributor of GeoStar and TETCO geothermal equipment.

A GeoStar unit can reduce your annual costs for heating, cooling and hot water by as much as 70% per year. No other gas furnace, air conditioner or heat pump comes close.

Geothermal heat pumps don’t create energy, they simply move it. Only a small amount of electricity is used to circulate heat to and from your home. This allows GeoStar units to provide $5 of heating for every $1 of electricity used, while current “high-efficiency” fossil fuel furnaces provide only 98¢. Our units are far more efficient than any conventional furnace!
