"We purchased our home just a few days ago and the heat was not working, and we were in single digit temps in this area. Josh, our tech, came out and checked everything out and discovered it was a programming issue on the digital thermostat. He set it correctly and heat is now working. The level of service of Hartman is phenomenal! Vickie in the office deserves a big thank you as the house was at 45 when I called and she saw to it that we were worked into their busy service request schedule."

"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!"

"We could not be happier with our service, estimate for a new system and most of all offering to but coolant in the system to give us AC until new system is installed."

The ducts that deliver conditioned air to all the rooms in your home are hidden from view, so you may not realize how their condition impacts your comfort. If the ducts are leaky or not properly insulated, as much as 30 percent of your HVAC system's output may not arrive at the registers. Professional duct sealing can eliminate this needless waste and boost your day-to-day home comfort.
The benefit of a central air system is that it allows your entire home's temperature to be controlled from a single thermostat, with a single HVAC installation. But it also comes with a serious drawback: the ducts that deliver air to your living areas can develop leaks or tears that bleed off conditioned air before you can make use of it. When your ducts pass through crawl spaces and other passages outside of your living areas, this can lead to

Duct sealing is one of the easiest and most effective ways to improve your HVAC system's efficiency. In the average Indiana home, around 20 percent of conditioned air is wasted due to leaky ducts.
