"Brian showed me what was wrong with my air conditioning unit and explained everything so I could understand. He spoke to Vicki at the office regarding a needed part that would have to be ordered. They could have slapped a generic part on, but it would have only been a short-term fix. Instead of taking the easy way out, they are getting the part made for my unit so it will stay fixed, and they are coming back to finish the job as soon as they have the part. Hartman Brothers is ethical, knowledgeable, friendly, and they do the job right! I highly recommend them!"

"Josh was very courteous and professional. He took the time to explain to me and show me what was going on inside the furnace. I felt really bad that we needed to call him out on a Sunday but with the inside of the furnace iced up our air just wasnt working and he got us up and running in no time"

"Ked came on time for my semi-annual scheduled appointment, checked out the furnace and changed the filter. He spent a considerable amount of time trying to track and fix a problem with my smart hub, but stayed with it until we think it is fixed. This is the third HVAC system I have purchased from Hartman Brothers over the past 40 years and I have always been pleased with their service, product and personnel. That is why I still use them. Took them awhile to convince me the annual maintenance program is a good deal, but with all the electronics in the new systems, the system needs care and feeding from a professional! I am glad I finally listened!"

"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."
