"We replaced a heat pump hvac system, got pricing from 4 hvac contractors. Lots of choices and levels but Hartman was head and shoulders above the others in cost and quality. They have experienced Technicians and great Owners, we highly recommend them!"

"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.

"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."

Geothermal heating and cooling systems are gaining in popularity in the United States. They provide energy-efficient heating in the summer, by transferred heat energy from a few feet underground into the home, and cool your home in the summer by depositing heat energy from the home back into the ground. They manage this heat-exchange process by transferring the heat via a system of pipes, usually excavated and installed underground.
Geothermal heating and cooling systems are the most energy-efficient home comfort systems you can buy. Rather than burning fossil fuels for heating or using ozone-depleting refrigerants for cooling, a
