Service Mechanical Industries was created in 1992 when Don Olsen purchased the commercial HVAC service and construction division from JWP Corporation (Jamaica Water and Power, Jamaica, N.Y.).  JWP was a consolidator that purchased HVAC and electrical contractors in the 1980’s.  They had a local office in Oak Brook, IL.  Service Mechanical Industries opened their first office in Northbrook, IL.  In 1995, Bob Cesario joined Service Mechanical as a partner.  Don and Bob have grown the company into a reputable service and design/build firm serving the entire Chicagoland area.

Service Mechanical has full design/build capabilities and is a recognized professional design firm of Illinois. Our design engineers utilize their experience and expertise to analyze existing mechanical systems and resolve problems, providing the customer with effective solutions.

We design new systems which provide quality comfort while maximizing energy savings.  Our engineers work closely with architects, builders, and owners to evaluate the specific needs of a project.  Through the use of Computer Aided Drafting (CAD), we identify the parameters of the project, qualify the mechanical needs, control the cost of construction, and minimize the cost of operations.
