"My experience was excellent. The furnace runs very quietly and before when it would come on and I was sleeping it came on so loud it would wake me up. I'm so pleased with Hartman Brothers.
My AC stopped working I thought it had something to do with my thermostat but Hartman's checked things out and found out someone turned the power off in the garage."

"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.

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.
