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 had an excellent experience with Hartman Brothers from start to finish. After dealing with an incomplete and frustrating repair from Peterman Brothers, Hartman Brothers was a breath of fresh air. Their technician spent several hours thoroughly troubleshooting my tankless water heater, walking through the issues clearly and professionally. There was no upselling, no pressure, and no shortcuts—just honest, methodical work. Based on their findings, I chose to upgrade to a new tankless water heater, and the decision was entirely mine. At no point did they try to push a sale or steer me toward anything unnecessary. The installation was clean, the communication was excellent, and the entire process felt transparent and trustworthy. It’s clear why they have such a strong reputation in the Fort Wayne area. Their professionalism, responsiveness, and genuine customer‑first approach really stand out. I’m very happy with the new system and with the service I received. "

"I had just called in yesterday for a non-emergency plumbing repair and they were out first thing this morning! Brad was very professional and courteous and he got everything taken care of very promptly. He had to go get a part and was back faster than I thought he could be. Great job and I will call again for my plumbing as well as my HVAC needs."

"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."

"We installed our new HV/AC and on demand water heater last year. The result is money saved year around. No huge water heater taking up space. And a great crew at Hartmans to service our unit in years to come. Great folks to do business with. Thank you!"
