"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."

I inquired about the root cause of this recurring problem and he kindly explained what was occurring to prevent the furnace from igniting, and what he had done to resolve the current issue, which I appreciated very much! As always, I remain a happy Hartman Bros. customer!"
