I initially called champion to come out to service my AC because it was not cooling. The first technician that came out made some repairs that got the system running. After a week our AC was not cooling again. I called champion with our complaint and requested a more experienced technician. They sent out Aaron Christianson and he did a great job. He was very knowledgeable and explained everything that was wrong in detail. He offered all the options and helped us make the best decision for our home. Aaron's great service has made champion the only company that I will use or recommend for AC repair.
