"Hartman Brothers installed the HVAC system before we bought this home, and has always maintained it. When it was time to replace it after 32 years, we selected them to install & maintain this system as well."

"Our technician arrived as scheduled, was courteous at the door and asked if it was OK to come into the house, after which he put his booties over his work shoes. He (I wish I knew his name) seemed to complete his tasks efficiently, cleaned up his workspace and gave a thorough rendition of the condition of our AC unit. I appreciated his work and glad that we had the service contract. Great Job!"

"Our air conditioning went out today. My husband called Hartman Brothers. They were here within 30 minutes. I can’t remember the guy’s name but he was very nice and did a great job! Hopefully we won’t have any more problems but if we do, we’ll call Hartman’s."

"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.

However, if you notice a loud humming or buzzing noise, your unit is probably malfunctioning. Several issues can cause a humming air conditioner. Let's take a closer look at them along with their solutions.
