"Great first impression with the receptionist who answered my call after the first ring! She was friendly, professional, and genuine... The service repair technician was professional and took time to explain the repair that he recommended to the A/C unit. He fixed the unit on the spot. Not only great service, but great people too. Thank you, Hartman Brothers!"

"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.
