When you're in the market for a new HVAC system, look for one that has an electronically commutated motor (ECM) outfitted for variable speeds as part of the furnace or air conditioner. These motors offer significant advantages over permanent split capacitor (PSC) motors because they use less electricity, run more quietly and adapt their speeds to conditions in your home. Also known as a variable-speed blower motor, an ECM with a motor controller can operate at whatever speed is needed to meet the conditioning needs of your home and the specific airflow and filtering factors in your HVAC system. For example, if your air filter is dirty, a variable-speed ECM will ramp up its speed to compensate for the restricted airflow.

"I have called Hartman Bros twice for problems with my home air conditioning. Both times I felt that the pricing was fair. I appreciate that they seem to start with trying to repair and not jump to replace."

"AMAZING customer service!! My a/c went out this weekend - yes, THIS weekend the hottest weekend of the year. I called the office and they were able to have a service technician out within 5 hours. The truck was a sight for hot and sore eyes for sure. He did a wonderful job finding and fixing the problem as quickly as possible. 10/10 highly recommend!!"

"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!"
