How much does air duct replacement cost for a typical home?

Air duct replacement cost for a typical home varies widely and is confirmed only after an on-site inspection. The biggest price driver is your home’s size and how easy it is to access the existing duct runs. Final totals also depend on material choice and how many supply and return lines must be replaced or added. Our local Marion team regularly replaces ductwork in everything from tight crawlspaces to long attic runs, and we’ve learned that sharp turns in cramped areas add labor more than materials. After evaluation, we provide upfront pricing before work starts.

What usually affects your duct replacement price:

• Scope of work: full system vs. sections
• Duct type: metal, flex, or insulated rigid
• Layout complexity: length, branches, and number of registers
• Accessibility: attic height, crawlspace conditions, and obstacles

If you see crushed, rusted, or mold-contaminated ducts, schedule an evaluation before running the system heavily.
