"My experience was excellent. The furnace runs very quietly and before when it would come on and I was sleeping it came on so loud it would wake me up. I'm so pleased with Hartman Brothers."

"Our AC went out and they sent someone out within a few hours and the problem was fixed quickly. With our service membership we also got a discount so the repair price was reasonable. I was very impressed with how quickly and professionally they fixed the problem especially in the middle of summer when they must get a lot of AC calls. Will definitely continue to use Hartman Bros."

"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."
