Mr. Bowler responded to my request promptly, came by the house at a time that fit my schedule and gave me a very reasonable quote to fix my system, explaining everything in detail. He was back at the exact agreed upon time, again working around my work schedule, to do the repair and done in no time. I am very satisfied, especially appreciated that no question seemed too small. He took the time to explain how my system worked, which my home builder and original installer never had the time to do. Will definitely use his services in the future.
