"The staff is wonderful and the technicians are "top notch" at Hartman Brothers! I have used this company for the past 25+ years for all my regular maintenance checkups and repairs. I have never been disappointed with the quality of work by the Hartman Brothers service technicians. My most recent service tech was "Josh." Josh was very courteous and professional. I will continue to use Hartman Brothers for all my HVAC needs for years to come!"

"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.
