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

Air duct replacement cost for a typical home is confirmed after an on-site evaluation because pricing depends on your home’s layout, total duct length, material, and access conditions. The biggest driver is usually how much duct must be replaced and how easy it is to reach in attics, basements, or crawlspaces. Many homes need only partial replacement or sealing, while full redesigns are chosen when ducts are rusted, undersized, or collapsed. Our technicians often find that resizing a few key trunks restores airflow better than replacing every branch. We handle sealing, ventilation cleaning, and full duct redesigns with upfront pricing, and we regularly complete this work for homeowners in the Delavan area.

What affects the final price:

• Full system vs. targeted sections
• Sheet metal vs. flex/insulated duct
• Attic/crawlspace access and removal labor
• Airflow redesign, sealing, insulation, and balancing
