"We could not be happier with our service, estimate for a new system and most of all offering to but coolant in the system to give us AC until new system is installed."

"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.

"Brian showed me what was wrong with my air conditioning unit and explained everything so I could understand. He spoke to Vicki at the office regarding a needed part that would have to be ordered. They could have slapped a generic part on, but it would have only been a short-term fix. Instead of taking the easy way out, they are getting the part made for my unit so it will stay fixed, and they are coming back to finish the job as soon as they have the part. Hartman Brothers is ethical, knowledgeable, friendly, and they do the job right! I highly recommend them!"

"They worked me in early. Inspected and found the problem quickly. Explain the issues thoroughly and did not attempt to see me parts and services I did not need. They got the heat going temporarily and hope to have needed parts in a couple days."

For more than two years, there has been a legal battle between the U.S. Department of Energy (DOE) and several HVAC trade organizations over regional HVAC system efficiency standards. The long-running dispute has come to a close with a recent court decision that accepted a joint settlement agreement that was filed on March 11.
About 40 percent of the energy consumed by the U.S. residential sector is for space heating purposes. That makes raising gas furnace efficiency standards a huge target for
