Our History
Air Design Systems, Inc. has been in business for over thirty-two years providing innovation, quality, and safety in the heating, ventilation, and air conditioning trade. Established in 1977, our woman owned business has grown from estimating jobs inside a small house near Brookfield, IL to a large 42,000 sq. ft. facility in Willow Springs, IL.

When an industrial or commercial area is being built or renovated, having Air Design Systems, Inc. as your contractor will keep the project on schedule and on budget while at the same time
remaining safe. Air Design Systems, Inc. uses the latest software and hardware in computer aided drafting (CAD), 3D clash detection, and BIM management.

Our shop alone has 36,000 sq. ft. dedicated in helping your project save time and money. We know that there will be unexpected changes on a job, but with our state of the art fabrication system and our experienced sheet metal workers, you can rest assured that your job will be completed on time and with excellence.
