"Extremely pleased with their work! When I say I'm a picky customer, I really mean it (I'm a Training Manager for an HVAC manufacturer). These guys showed up precisely on time, were extremely courteous and professional, and did an outstanding job on my system. They were very careful moving the equipment to my mechanical room (not an easy task), did a very neat job on the install, and cleaned up so that everything was spotless when they left. I even gave them an opportunity to do a "shortcut" on my install, but they refused and said "that's not the way we do it." It was easy to tell that these techs took PRIDE in the work they were doing. I can't even begin to tell you how much I would recommend this small business from New Haven, IN to do any HVAC work. If you want a courteous, professional install at a reasonable price, call Hartman Bros!"

"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.

"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!"

"Came home from work to find that my furnace wasn't working. Since the temperatures were extremely mild for November, I just left a message for them to call me the next day. Received a call by 7:25 am and told that the repair man would be there in approximately a half hour. He was at my house by 8:30 and he had it back running within 45 minutes. He went the extra step and made sure that there was no other possible issues before he left. I'd recommend Hartman Brothers Heating to anyone, they are courteous, reliable, knowledgeable and won't gouge you like some companies."

Carbon monoxide (CO) is a gas that can leak into your home and cause life-threatening symptoms. Since this gas doesn’t have any color or smell, it can be difficult to detect on your own. Read on to find out more about carbon monoxide poisoning, including how to lower your risk of this dangerous condition.
Everyone's getting into grilling these days. And why not? It's an easy way to cook for company, and you eliminate cooking odors and mess from the indoors. But grilling, as with anything using combustible fuels, should be conducted with care. We're not just talking about preventing fires and explosions, but also eliminating negative effects on IAQ, or indoor air quality.
Your heating system, cooking equipment, and any other appliance that burns fuel create carbon monoxide (CO). Normally, this toxic gas is safely vented outside. A CO leak can be lethal, making it necessary to have a carbon monoxide detector in your home. While manufacturer's instructions for CO detector placement vary, there are some general rules you should remember.
