"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!"

"As always, Hartman Bros does service RIGHT! They are prompt, courteous, professional, clean and fairly priced for all services we've ever had completed. We were introduced to them in 1998 when we first used their services and have been faithfully returning for every Heating and Air need, including the building of 2 new homes. They are stellar performers providing excellence at a time when mediocrity has been touted as the norm in our society. They go well above and beyond in all they do."

"They worked me in early. Inspected and found the problem quickly. Explain the issues thoroughly and did not attempt to see me parts and services I did not need. They got the heat going temporarily and hope to have needed parts in a couple days."

"My experience was excellent. The furnace runs very quietly and before when it would come on and I was sleeping it came on so loud it would wake me up. I'm so pleased with Hartman Brothers."

"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."

Heat ducts in a house are usually installed in the floor or the ceiling. But which one is preferable? Both locations have positives and negatives, depending on a number of variables.
Note: No matter where you place the ducts, fundamental facts of duct design always apply: The size of ductwork must be properly calculated to accommodate the required airflow volume and duct spans should be routed with as few sharp bends as possible.
The average homeowner spends 20 to 30 percent more energy than necessary for cooling and heating bills due to leaky and inefficient ductwork. If you are constructing a new home or 
A smart way to boost energy savings in your Fort Wayne area home is to view it as an entire system, rather than a collection of parts. A weakness in one area compromises the strength and efficiency of others.
