Mechanical Contractors Association of Chicago

The Chicago MCA is a professional association representing contractors in mechanical construction.

MCA contractors work with the highly qualified pipe fitters and service technicians of Pipefitters Local Union 597 to build the powerhouses that generate your electricity; install and service heating and air conditioning systems in homes and buildings; and install piping wherever it's needed: – from oil refineries, to pharmaceuticals, to food processing plants.

The MCA of Chicago is here to help those contractors maintain their edge in mechanical construction and service through education, marketing, and negotiations with the union that provides the most professional pool of workers available in the industry.
