When it comes to quality of work the guys over at Champion AC are second to none. I have brought some seriously strange and rare problems to them and each and every time they are able to solve the problem without breaking a sweat. My only issue with them is that I wish they would call ahead of time to let you know they are on their way. Other than that though, the price is great, I have never had to have them come back for the same job, and the technicians are very professional and friendly!
