Chicago is one of the largest data center markets in the country. Hyperscale and colocation campuses keep expanding through Elk Grove Village, Aurora, and the O'Hare corridor, and every one of them runs massive chilled-water plants that need technicians around the clock.
Data center and critical facilities roles in Chicago
Chicago's climate cuts both ways: data centers here need cooling expertise for dense server halls and real heating and boiler knowledge for brutal winters. Technicians who can handle large central plants, cooling towers, and building automation systems are in steady demand, and new campus construction keeps adding commissioning and start-up work on top of ongoing service.
