We've been doing business with Champion AC ever since they originally installed our A/C unit for us about a year ago. The initial installation process was a little shaky because we ran into some small problems along the way but they were able to quickly sort things out and everything worked great. Whenever we need help from them we give them a call and they are able to quickly come out to assist us. Most recently we had some maintenance work by them and they were very thorough. I would highly recommend their services to anyone.
