About Us

Service at Work

ATMAC Mechanical has been working for D/FW clients for more than 50 years. Founded in 1953 as Atlas Refrigeration and Air Conditioning, ATMAC has grown and added new service lines along the way. In 2005, the name changed to ATMAC Mechanical Services to show the attention to commercial service and construction.

Sure, clients come to us because ATMAC delivers quality. But they stay for the service we provide every day. We treat each client the way we would want to be treated. Every one here works that way. It makes it easy to deliver the best work on the job site, in the mechanical room, or on the roof.
