For several years we have been using Southwest Air Conditioning and Heating. We are very pleased with the quality of their services and the excellent customer service that they provide. This last time they came out for a simple fix. The technician replaced a filter after reviewing some issues we were experiencing. Everything is now running great again! Over the years we have had quite a few problems with our equipment and Southwest Air Conditioning and Heating always seem to be able to find the answer. It is so convenient to set up an appointment and the techs are always prompt. We recommend them to everyone.
