"Extremely pleased with their work! When I say I'm a picky customer, I really mean it (I'm a Training Manager for an HVAC manufacturer). These guys showed up precisely on time, were extremely courteous and professional, and did an outstanding job on my system. They were very careful moving the equipment to my mechanical room (not an easy task), did a very neat job on the install, and cleaned up so that everything was spotless when they left. I even gave them an opportunity to do a "shortcut" on my install, but they refused and said "that's not the way we do it." It was easy to tell that these techs took PRIDE in the work they were doing. I can't even begin to tell you how much I would recommend this small business from New Haven, IN to do any HVAC work. If you want a courteous, professional install at a reasonable price, call Hartman Bros!"

"I've had Hartman's install new Bryant H/Vac systems in 2 houses now and I've been pleased with the outcome at both houses. They are local, on time and reasonably priced. I've had a couple minor problems and Hartman Bros treated me fairly and took care of the issues. You don't buy 2 complete H/Vac systems from someone you don't trust or has treated you unfairly."
