"Love these people! We bought a brand new furnace and ac a year ago. For some crazy reason something happened to the ac Sunday when it was 91 degrees . I had a service guy here Sunday and Monday... Vicky was fabulous through it all and the guys were wonderful. They ended up working after hours and got it all fixed... Thank you from the bottom of my heart and my puppies. We're cool again!!"

"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.

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.
