"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!"

"Josh was very courteous and professional. He took the time to explain to me and show me what was going on inside the furnace. I felt really bad that we needed to call him out on a Sunday but with the inside of the furnace iced up our air just wasnt working and he got us up and running in no time"

"Josh at Hartman Brothers did a good job. He quickly figured out the problem and got it fixed for 1/3 the cost I was expecting! He did not "find" problems or try to get us to upgrade, just did exactly what we needed him to do. I would strongly recommend calling Hartman Brothers for installing or repairing your AC/Heating!"

The concept of HVAC has been around for thousands of years. The ancient Romans and Greeks used channels under marble flooring to distribute heat. However, it was until 1902 that the modern A/C idea was launched by Willis Carrier. Today's systems have experienced tremendous technological upgrades that make them significantly different from the older ones. Let's explore the recent HVAC history that has contributed to that.
