Southwest Air Conditioning and Heating has always provided very good service to us! We were having some problems with the upstairs of our home getting cool, so we asked them to look at it for us. Their tech came out and he went to every ceiling vent in the house to test the air flow, and then to the attic to check the boxes up there. We have a geothermal system, too, so he even checked that. And, he checked all around the outside of the house. He was very thorough, and he took the time to explain everything to us. That really impressed me. Plus, I am impressed by their quick response time. This is summertime, and it is very hot, and they still managed to give us same-day service! Southwest is a good company!
