Sean showed up with a total product knowledge of both my systems. He was quickly able to diagnose the problem which others had overlooked. Not only was he able to provide a definite solution but took the time to explain to me, in layman's terms,what was wrong, what it would take to provide a solution and time line to completion. Very rare these days. He was extremely knowledgeable, polite, professional, thorough, and complete through clean up process. He also went the extra step to adjust my system to new advances that had occurred since installation years ago. It was a pleasure to know someone of his caliper was handling one of my household's primary and expensive components. Thank you again to Sean.
