We got our start with one focus — refrigeration for Cincinnati’s businesses in 1938 as 20th Century Refrigeration. In 1963, we became 20th Century Air Conditioning and operated under that name until 1999, when we became Century Mechanical Solutions, Inc. We changed our name to better describe how our company had grown to meet the increasing complex and varied solutions needed by our customers.

The business grew under the leadership of the late Frank B. Lienhart Sr., a professional engineer with more than 40 years of experience in the design and installation of air handling systems.
