"I've used Hartman Brothers for all my HVAC needs across multiple properties and they are always responsive and timely. Dalton was my technician and demonstrated a high degree of both professionalism and helpfulness. Vicky is their jack-of-all trades office and scheduling manager. She always does a phenomenal job and makes you feel valued as a customer in every interaction. You can't go wrong with this company. Strongly recommended!"

"Josh was very knowledgeable! He was able to find the problem with our furnace and fix it. He was not pushy and didn't try to sell us anything we didn't need! We will definitely do business with Hartman's again when needed!"

"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.

"Always a tremendous experience with Hartman Brothers. I have used them for more than 25 years and gotten to know their people more like friends/family than vendors... because that's exactly how they treat their customers! Always a pleasure to deal with and their work is exceptional as a bonus. Would give them 6 Stars if it was an option."
