Cost to Ductwork Installation in Kansas City, MO (2026)
If you’re budgeting a ductwork installation in Kansas City, most projects run $1,951-$7,803, 2% below 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 Kansas City 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.
