About Us

O'Hare Mechanical Contractors, Inc. has been serving Chicago and the suburbs since 1966 as a union H/V/AC contractor. We specialize in the design/build and plan/spec of commercial and industrial Heating, Ventilation, and Air Conditioning Systems for both new construction and existing systems. We install new or replace existing roof top units, warehouse space heaters, exhaust systems, ductwork, make up air units, fresh air intakes, air rotation units, and more. We have the experience of several engineers, estimators, and project managers to serve you better. O'Hare Mechanical works closely or can subcontract with union pipe fitters, insulators, electrical/control contractors, test and balance, and roofing contractors in order to complete a full project. For large projects or small, whether your project is design/build or plan/spec, please contact us for further assistance.
