We've been using Southwest Air Conditioning and Heating for thirty years. They originally installed the air conditioning unit out at our ranch house, so when the outside part started giving us trouble, I knew who to call. They went all the way out to the boonies to take care of replacing it for us. I can always count on Southwest Air. They are a great company. I usually deal with Russell. He takes good care of me. This time, he brought another fellow with him and he was really nice, too. The guy in the office also takes really good care of us whenever we call. Southwest Air Conditioning and Heating has always done a good job for us and we'll continue using them for our main house and the ranch house. Five stars for a great company!
