"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."

"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.

"Tech was polite, professional, knowledgeable and worked quickly to resolve the issue with my furnace. I inquired about the root cause of this recurring problem and he kindly explained what was occurring to prevent the furnace from igniting, and what he had done to resolve the current issue, which I appreciated very much! As always, I remain a happy Hartman Bros. customer!"
