"Came home from work to find that my furnace wasn't working. Since the temperatures were extremely mild for November, I just left a message for them to call me the next day. Received a call by 7:25 am and told that the repair man would be there in approximately a half hour. He was at my house by 8:30 and he had it back running within 45 minutes. He went the extra step and made sure that there was no other possible issues before he left. I'd recommend Hartman Brothers Heating to anyone, they are courteous, reliable, knowledgeable and won't gouge you like some companies."

"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.

"Hartman Brothers installed the HVAC system before we bought this home, and has always maintained it. When it was time to replace it after 32 years, we selected them to install & maintain this system as well."
