Duct replacement is priced mostly by labor hours. Tight crawlspaces and low attics can add 30–50% over an open, walkable space.

Frequently asked questions

How much does it cost to replace ductwork?

Whole-home duct replacement usually runs $3,500 to $12,000 in 2026, or roughly $2 to $4 per conditioned square foot.

Should I replace ducts with the HVAC system?

If ducts are over 20 years old, undersized or badly leaking, doing both at once saves labor and protects the new system's efficiency rating.
