Company History

The business began in July 1972 when Irving Lieberman left several larger engineering firms after serving as a chief engineer. He opened his own practice to focus on hands-on building systems work for local clients. Over the decades the firm handled projects for homes, small offices, and light commercial buildings in suburban Cook County.

In time the next generation stepped in. Morris, Irving’s middle son, joined the practice after graduating in mechanical engineering from IIT, the same school Irving attended. That family continuity has shaped how the company designs systems and supports clients today.

Leadership

Morris leads daily operations and project engineering. Both Morris and Irving are trained mechanical engineers from IIT, and they emphasize practical solutions that fit local housing stock and weather patterns. Their work reflects experience with Midwestern heating loads, basement plumbing concerns, and older ductwork common in Mount Prospect homes.

The leadership stays active with contractors, building managers, and architects in the area to keep projects moving on schedule.
