My experience with the service of Caliber Door systems was very impressive. My 1 remote would not work. When I called Tony, he was wonderful. He was able to diagnose it immediately. He asked me if I had access to the unit, I did as I had stairs up to the attic of my garage. Once he had instructed me on what to press, he insisted that I get down from the attic before he would terminate the call. Professional, knowledgeable and caring!
