Cost to Ductwork Installation in Chicago, IL (2026)

If you’re budgeting a ductwork installation in Chicago, most projects run $2,335-$9,339, 17% above the $3,800 national average. What moves that number most is usually one thing: Duct Material: Flex vs. Sheet Metal vs. Fiberglass. On its own it can swing the cost by $3 - $20 per linear foot, so that’s the decision to slow down on before you sweat the smaller stuff.

Easiest place to save: Before replacing ducts, have a duct leakage test done ($150-$300) - if your system leaks less than 10% of total flow, sealing may be sufficient instead of replacement, saving thousands.

In the Midwest (where Chicago sits): Many homes have accessible basements which simplifies installation significantly. Labor costs are near the lower end of the national range. Cold winters make duct insulation in unheated spaces a priority - budget for R-8 wrap on any ducts outside conditioned space.
