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

Air duct replacement cost for a typical home varies widely and is only confirmed after an on-site inspection and duct sizing assessment. The biggest cost driver is how much ductwork is needed for proper airflow, followed by how difficult it is to access and replace. A well-designed replacement can also cut noise and fix hot and cold spots better than patchwork repairs. If ducts are rusted, crushed, moldy, or undersized throughout, full replacement is often smarter; if problems are isolated, targeted repairs can work. Our technicians regularly replace duct systems in the Hiller area and provide pricing after verifying access points and local code needs.

Expect your estimate to reflect these specific factors:

• Total linear footage and number of supply/return runs
• Material choice (flex, sheet metal, or ductboard) and insulation level
• Access conditions in attic, crawlspace, or behind finished ceilings
• Added returns, dampers, or redesign for airflow balancing
• Sealing method and post-install performance testing
