"A heating unit in my barn had stopped working. This unit was originally installed by Harman Brothers years ago. Josh opened the unit up and within 30 minutes he found the problem and had it repaired."

"We installed our new HV/AC and on demand water heater last year.
The result is money saved year around. No huge water heater taking up space.
And a great crew at Hartmans to service our unit in years to come. Great folks to do business with. Thank you!"

"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.

"My toilet was not functioning correctly and i was going to call someone to fix... my son in law said call Hartman...i think they do plumbing, too. I didn't know that! Hartman has taken care of my heating/air since 2001 so i didn't even hesitate to call! Brad was great and was able to remedy the issue quickly. He was polite and knowledgeable! He also showed me where to turn my water off for future reference. Another great experience with Hartman!!"

"I had ample notice of arrival via text. Technician picture was provided for safety and I appreciated that. Kept a clean work area and wore shoe covers inside the house. I had questions about the maintenance plan I had purchased in advance. The technician reached out to the office and clarified for me—the office was prompt with answers and the technician was very friendly, helpful and professional. We will certainly continue to purchase the annual maintenance visits with Hartman Brothers!"
