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. "

"On Saturday, my water heater spewed lots of water in the utility portion of my garage. Unfortunately, my furnace was soaked. After my call to Hartman Bros., Darian arrived within the hour and dried out the furnace and re-started it. Hartman Bros. has been servicing my heating and cooling systems for over 30 years and have always been "johnny-on-the-spot" when I have had problems. I highly recommend them."

"The serviceman was on time, did a very thorough job, and helped me with a couple of other small issues with the thermostat and A/C at the same time."
