"AMAZING customer service!! My a/c went out this weekend - yes, THIS weekend the hottest weekend of the year. I called the office and they were able to have a service technician out within 5 hours. The truck was a sight for hot and sore eyes for sure.
He did a wonderful job finding and fixing the problem as quickly as possible. 10/10 highly recommend!!"

"Ked came on time for my semi-annual scheduled appointment, checked out the furnace and changed the filter. He spent a considerable amount of time trying to track and fix a problem with my smart hub, but stayed with it until we think it is fixed. This is the third HVAC system I have purchased from Hartman Brothers over the past 40 years and I have always been pleased with their service, product and personnel. That is why I still use them. Took them awhile to convince me the annual maintenance program is a good deal, but with all the electronics in the new systems, the system needs care and feeding from a professional! I am glad I finally listened!"

"I absolutely loved the service we received from Hartman Brothers. They gave us an appointment right away, and the technician knew what our issue was based on my husband's conversation with the scheduler. As a result, he came prepared to fix our problem. The technician was also very nice and courteous. I would recommend everyone to give them a call for all your HVAC needs. Thanks Hartman for a job well done!"

"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.

You can think of refrigerant as the blood of your air conditioning system. When the system runs low on this vital fluid, it can't operate at optimum performance. As a result, you may notice changes to your home's comfort levels. Watch out for these signs of your A/C system having low refrigerant.
