I like using Southwest Air Conditioning and Heating because their staff is easy to work with, they can schedule appointments quickly and around the time frame that works for me and their pricing is reasonable. I had them come out recently and the technician was prompt, polite and professional. He was able to assess the unit quickly then explain his findings from the assessment to me. He said we need to replace the motherboard to the unit to control the heat. He explained everything to me then asked if I had any questions. With my approval, he ordered the part. It took two days to come in and he came back to install it yesterday. Everything is working fine now. The technicians are always prompt, polite and professional. They are knowledgeable and respectful. They are courteous and friendly. I like working with the people at Southwest Air Conditioning and Heating.
