"Tech was polite, professional, knowledgeable and worked quickly to resolve the issue with my furnace. I inquired about the root cause of this recurring problem and he kindly explained what was occurring to prevent the furnace from igniting, and what he had done to resolve the current issue, which I appreciated very much! As always, I remain a happy Hartman Bros. customer!"

"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!"

"22 years ago Hartman's installed our furnace/AC. When the unit recently started having serious issues Hartman's tried to repair the unit, spending a few hours but the aging unit had given all it could and wouldn't stay fired after the flame sense was cleaned and the rest of the unit examined.
That tech, who's name I have unfortunately lost - possibly Jim, thoroughly explained everything during his inspection so I could relay the information to my husband.
After I discussed financing options with Hartman's for the replacement Rick Hartman cared for every detail and made the transition seamless. Our issue began on 3/10 and the replacement unit was installed on 3/14; a needed part was driven overnight to meet the installation date. Kevin and Jason from the install crew were very knowledgeable, professional and quickly fabricated a 3 in metal base for a perfect fit. This crew comes prepared! Josh set the unit air force specs 4 times until we found my personal preference. Roger Hartman came out during installation to give us our paperwork and check with the install crew. The installation was completed in 7 hrs and the crew never took a break! I would hire Hartman's any day for a red carpet customer service satisfaction experience with a company that has a great reputation, a friendly and professional crew with many years of accumulated experience, all the employees clearly work well together and have excellent knowledge and workmanship and work ethics. I highly recommend Hartman's, you won't be disappointed. They not only arrived on time but we're actually a little early!

"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!"

"Always a tremendous experience with Hartman Brothers. I have used them for more than 25 years and gotten to know their people more like friends/family than vendors... because that's exactly how they treat their customers! Always a pleasure to deal with and their work is exceptional as a bonus. Would give them 6 Stars if it was an option."

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.
