Roberts Environmental Control Corporation
Building on a Legacy of Precision, Performance, and Integrity Since 1949

Roberts Environmental was founded in 1949 by Leo Wasniewski as Roberts Refrigeration, focused on refrigeration and heating systems. In 1973, the company was incorporated under its current name, marking a strategic evolution into a full-service mechanical contractor. Today, Roberts delivers expert solutions in pipe fitting, sheet metal, HVAC systems, controls, test and balance, and 24/7 service and maintenance.

We serve commercial and industrial clients across Illinois, Indiana, Wisconsin, Ohio, and New Mexico. From food processing to manufacturing, cleanrooms to hospitals, our work spans the most demanding facilities — and we deliver with unmatched skill and professionalism.

In 2011, Cory Wasniewski, an accomplished aerospace engineer, joined the business. Today, he leads the company alongside Jim Wasniewski, guiding a team of seasoned union tradespeople, project managers, and technical specialists. Our team-first culture ensures collaboration, quality, and accountability at every stage — from concept and design to fabrication, commissioning, and long-term service.
