Commercial AAON Rooftop Unit Maintenance and Repair Service

AAON rooftop units are serious pieces of commercial equipment. They're built tough, but they still need regular, skilled attention to keep performing the way your business depends on them. That's exactly what we're set up to do.

Here's what we were working with on this one - a large commercial AAON RTU sitting on a flat commercial roof. When you open one of these units up, you're looking at a dense wall of control boards, fusing, contactors, compressors, and refrigerant lines. It's not a job for someone who just knows the basics. Our certified technicians know this equipment inside and out, and that matters when something goes wrong or when you're trying to prevent it from going wrong in the first place.

This is exactly why we put so much emphasis on our preventive maintenance programs. A PM visit isn't just a quick check - it's a thorough inspection of all the mechanical and electrical components, refrigerant levels, controls, and more. Catching a failing contactor or a refrigerant issue before it becomes a full breakdown saves businesses real money. An unplanned outage in the middle of a busy day costs far more than a scheduled maintenance visit ever will.

We serve businesses across Ann Arbor, Washtenaw County, and all of Southeast Michigan. Whether you need a one-time commercial HVAC repair, a full RTU replacement, or a customized PM program to protect your equipment long-term, we handle it all. Our team works around your schedule to keep disruptions to a minimum.

And if you're a homeowner in the area, our residential division brings that same level of care and technical know-how to home heating and cooling. One team, one standard - whether it's a commercial rooftop unit or a home system that needs attention.
