Southwest Air Conditioning and Heating came out to fix my air conditioning. The first HVAC technician was respectful, professional, and worked hard, but he could not find the problem. The next day another HVAC technician came out taking about 45 minutes to diagnose the issue and he was able to get it fixed. I think with the first technician there might have been a lack of experience, which is no big deal other than they had to come back another day. I have been using this company since they originally installed this HVAC unit. I will continue to use them.
