While I have fortunately not required their support beyond routine service appointments, I am confident in their ability to provide exceptional assistance should the need arise."

"A heating unit in my barn had stopped working. This unit was originally installed by Harman Brothers years ago. Josh opened the unit up and within 30 minutes he found the problem and had it repaired."

"Hartman Bros provides professional service always, all weather. My family has used them for more than 16 years - installation, repair and maintenance of air conditioning and furnace. Today (and always) Josh was on time, knowledgeable, professional and kind. Thank you again!"

"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!"
