"Josh was very courteous and professional. He took the time to explain to me and show me what was going on inside the furnace. I felt really bad that we needed to call him out on a Sunday but with the inside of the furnace iced up our air just wasnt working and he got us up and running in no time"

"Always a tremendous experience with Hartman Brothers. I have used them for more than 25 years and gotten to know their people more like friends/family than vendors... because that's exactly how they treat their customers! Always a pleasure to deal with and their work is exceptional as a bonus. Would give them 6 Stars if it was an option."

"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.

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
