Southwest Air Conditioning and Heating has done a lot of work for us, and in fact, they are the only heating and air company in the area qualified to work on geothermal systems like we have, and the only company that has the necessary equipment. They are friendly and professional people, and they always thoroughly check out the system when they are out here. Most recently, they replaced one of the motors that had gone bad. We highly recommend Southwest Air Conditioning and Heating to everyone. They take the time to do things right and we really appreciate that!
