My wife and I had trouble finding someone to come out to our area because we live near Pleasanton. Called Champion and on a Monday and they sent a tech out the same day. We upgraded our entire home to a high quality, efficient unit. The technicians were extremely polite, and performed quality work within a timely fashion. I would recommend Champion AC to anyone who is looking for quality work at the right price. I give them an A+. Job well done Champion!!!
