"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!"

"We didn't have to wait long for them to respond to our call. They fixed the problem, explained to us what happened, and explained to us what to do if the issue should occur again. Also, they have great customer service. We will definitely use them in the future if needed."

"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!"

The return air ducts are a key component of your HVAC system's air distribution network, but it's easy to overlook their importance since they don't send out heated or cooled air. To help you understand the vital role they play in maintaining your comfort and keeping the HVAC system working properly, let's take a closer look at what the return ducts actually do.
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 
Indiana homeowners depend on their HVAC systems to stay warm and comfortable through the heating months. Considering that home heating accounts for 45 to 55 percent of the typical energy budget, there is also financial incentive to maintain a well-operating HVAC system with a seasonal inspection.
