"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.

"Hartmans installed my HVAC and ducts about 5 yrs ago and I've done the maintenance agreement every year. Every tech that has come out has been informational, professional, and thorough."

"I absolutely loved the service we received from Hartman Brothers. They gave us an appointment right away, and the technician knew what our issue was based on my husband's conversation with the scheduler. As a result, he came prepared to fix our problem. The technician was also very nice and courteous. I would recommend everyone to give them a call for all your HVAC needs. Thanks Hartman for a job well done!"

"Jim went over and above as he identified a problem that other techs had not noted in the 2 years prior and took the time to educate us on the issue. We also had questions about our thermostat settings and while in our home, Jim researched and found the answer. Great service isn’t always knowing it all, but rather assessing situations, thoughtfully problem solving, and seeking answers from others when needed. Jim did all of that and we appreciate the excellent service provided."
