Headquartered in Dayton, Ohio, AMS was incorporated in 1974 as a Mechanical Contractor. Today, we employ over 300 professionals; maintain offices in Ohio; work in Indiana, Kentucky, West Virginia, and other regions; and continue growing and developing our core competencies, our in-house support services, and the scope of our operation.

“We are extremely proud of our growth, the enduring relationships we have built with our clients, and the one-of-a-kind services and support we offer,” says Michael G. Ayers, President.  “What makes AMS unique?  We employ a large, highly qualified work force.  All of our key support services (e.g., engineering) are maintained in-house.  We are a single-source provider to our clients, offering a full range of HVAC and plumbing services.  Finally, the AMS team is clearly focused on quality, safety, the environment, and the ever-changing needs of our clients.”

“I am confident of our continuing success,” adds Mike. “Our future—like our past—will be built on a solid foundation of client trust, responsiveness, and professionalism.”
