Air Care, Inc., provides geothermal (GeoExchange) heating and air conditioning systems for residential and commercial applications from their headquarters on Beaver Dam's southeast side...entirely conditioned with geothermal technology. Our geothermal experience began in 1994 with a residential installation in rural Horicon which has been operating trouble-free for 21 years. Scores of geothermal installations in homes and commercial buildings since have expanded our geothermal service radius northeast to Manitowoc, east to Port Washington, southeast through Milwaukee to Kenosha, south of Interstate 94 and west through Madison to Black Earth.
