I was really happy with the work that the people over at Champion AC did for me. My air had started doing some weird stuff and so I gave these guys a call and they were able to get someone out to my home that very same day. The technician that came out was very polite and friendly and he really knew what he was doing. He found the problem in my unit, and while he could not fix it right there because he did not have the part, he left and came right back after picking up the part. My unit has been working perfectly since and I have no complaints. Would definitely use these guys again.
