"Josh at Hartman Brothers did a good job. He quickly figured out the problem and got it fixed for 1/3 the cost I was expecting! He did not "find" problems or try to get us to upgrade, just did exactly what we needed him to do. I would strongly recommend calling Hartman Brothers for installing or repairing your AC/Heating!"

"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.

If you're tired of high utility bills, but want to stay cool over the summer, it may be time to try out a two-stage cooling system. Unlike traditional air conditioners that only have one setting on their compressor, paired with a variable air handler (or fan), a two-stage cooling system will actually have a variable speed on its compressor. This means with two-stage cooling, you can control how much cold air you're paying to generate at any particular time, as well as how fast it's being disbursed, making the system more energy efficient.
