"I had just called in yesterday for a non-emergency plumbing repair and they were out first thing this morning! Brad was very professional and courteous and he got everything taken care of very promptly. He had to go get a part and was back faster than I thought he could be. Great job and I will call again for my plumbing as well as my HVAC needs."

"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.

"They worked me in early. Inspected and found the problem quickly. Explain the issues thoroughly and did not attempt to see me parts and services I did not need. They got the heat going temporarily and hope to have needed parts in a couple days."

All gas furnaces use a heat exchanger to transfer the heat the gas creates. Normally, heat exchangers sit next to the furnace burners and heat up just like a pan on the stove. These parts, made from metal, absorb heat and the air that the blower sends over it warms. It enters the ductwork and heats your home.
When you turn on your fuel-burning heating system for the fall, you have a reasonable expectation that it will operate safely. However, some unforeseen issues could occur that might make your gas or propane furnace a potentially deadly risk. To prevent this danger, you need a 
Carbon monoxide (CO) is a real threat lurking in your Fort Wayne area home. This colorless, odorless gas is hazardous and potentially lethal to humans and animals. It can be emitted from any combustion appliance in your home, including gas-powered water heaters and furnaces, if they're malfunctioning or not venting properly. It is very important to identify CO leaks quickly and address the situation immediately before it endangers your family.
