Southwest Air Conditioning and Heating did a great job for us. Technician (Mario) arrived with 1 ½ hours of us placing a service call. He was very friendly and professional. Did diagnostics quickly and discovered problem. Replace part but looked further for reason the part went bad. Discovered a wire chewed by a rodent. Would have required a new wiring harness but Mario was able to pull enough wire that he could splice the wire, saving us a large expense. Total bill was extremely reasonable – in fact lower than I expected. Highly recommend Southwest Air Conditioning and Heating!
