HVAC in Chicago, IL

Chicago's HVAC market outpaces most Illinois cities, with 10 active opportunities in Q2 2026 versus a state average of 5 per city. Chicago ranks as the 3rd most active market among Illinois cities for federal HVAC contracting. Above-average activity suggests growing federal investment in this area, making it a strong market for contractors building a Illinois pipeline.

At the state level, Department of Veterans Affairs leads Illinois's HVAC procurement at 41% of awards, followed by Department of the Navy (37%). Contractors should prioritize building past performance with Department of Veterans Affairs and Department of the Navy, which together control the majority of local awards. These statewide patterns are a strong indicator of the buying agencies active in the Chicago area. Statewide in Illinois, the incumbent landscape is entrenched: the top 3 vendors hold 80% of recent awards.
