"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.

"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."

If it seems impossible to enjoy a consistently comfortable temperature from room to room, your home's single-zone HVAC system may be to blame. When there's just one thermostat controlling heating and cooling throughout a home, temperature variations and hot or cold spots aren't uncommon. Installing a zoning system can put an end to these issues and let you enjoy a whole new level of comfort.
Not all of the rooms in your Fort Wayne home are created equal — at least, not when it comes to heating and cooling demand. Your bedrooms need more attention during the night, for example, while you may have a guest room that's only in use once in a while, and a home office that needs heating and cooling during daylight hours. With a traditional 
In many homes, the thermostat can become a miniature, wall-mounted battlefield. One person will turn the temperature up, and minutes later a spouse or sibling will turn the temperature down – causing your HVAC system to work overtime, while leaving nobody truly comfortable.
