The Mechanical Contractors Association of Chicago has two new members: W.J. O’Neil Chicago and Therm Flo Inc.

W.J. O’Neil Chicago has worked on several high-profile mechanical engineering and construction projects including Ford Field, the home of the Detroit Lions; Volkswagen, General Motors and Ford plants and the University of Michigan Cardiovascular Center in Ann Arbor, Mich.

With more than 40 years in business, Therm Flo Inc. provides HVAC market services to commercial and industrial facilities throughout Chicago and northwest Indiana.

MCA Chicago Executive Vice President Steve Lamb said both companies’ reputations have landed them a spot in the contractor group.

“The Mechanical Contractors Association of Chicago is the leader of the union mechanical construction and service industry,” Lamb said. “W.J. O’Neil Chicago and Therm Flo Inc. have earned a reputation for providing excellent industrial installation and HVAC service, making them welcome additions to MCA Chicago.”
