"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.

Heat ducts in a house are usually installed in the floor or the ceiling. But which one is preferable? Both locations have positives and negatives, depending on a number of variables.
Note: No matter where you place the ducts, fundamental facts of duct design always apply: The size of ductwork must be properly calculated to accommodate the required airflow volume and duct spans should be routed with as few sharp bends as possible.
The average homeowner spends 20 to 30 percent more energy than necessary for cooling and heating bills due to leaky and inefficient ductwork. If you are constructing a new home or 
A smart way to boost energy savings in your Fort Wayne area home is to view it as an entire system, rather than a collection of parts. A weakness in one area compromises the strength and efficiency of others.
