"Excellent tech, found problem and repaired. Boiler had cracked wire cover, wrapped so it wouldn't arc and proceeded to order replacement. Also checked AC and showed husband where to shut off on outside so unit wouldn't kick on at same time everyday for just a minute or two,, even though AC was off for winter. Great Tech, Great Service! Also checked and placed order for ceiling heating unit for husband 's wood-working shop."

Jim did all of that and we appreciate the excellent service provided."
