"Mario was a friendly, polite technician. He answered my questions to my satisfaction. In my opinion, he fits the profile of all technicians from Hartman’s who we have dealt with— friendly but always professional."

"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.

"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!"

During the cooling months, your air conditioner probably uses more energy than any other system in your Fort Wayne home. Spring maintenance is important to ensure all parts are working correctly. It's also a good idea to familiarize yourself with air conditioner parts to understand energy usage and home cooling.
Despite their initial higher purchase price, higher-efficiency air filters can save you money in the long run, as compared to using standard-quality air filters in your forced-air heating or cooling system. Here are some of the more important ways higher-efficiency filters can do that:
Unless you live in an old farmhouse full of leaks and drafts, shutting a room to save energy is likely to backfire. A study done by the Lawrence Berkeley National Laboratory found that closing off registers in select rooms actually was more likely to increase energy use in energy-efficient homes. How is that possible?
