My AC unit stopped working on a 97 degree day.
Called John and he said he would be there the next day. He came, found two issues, fixed them both and only one was under warranty. He did not charge me for anything. This group is very honest and do a great job. Highly recommend Wehn Heating & Air Conditioning.
