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

Air duct replacement cost for a typical home is set only after an on-site evaluation, because it varies with the duct layout, access, and materials selected. The biggest driver is the total duct length and how hard it is to reach runs in attics, crawlspaces, or finished ceilings.

We’ll design the new duct system, remove and dispose of old sections, seal and insulate as specified, and balance airflow so rooms heat and cool evenly. We regularly handle full duct replacements across the Chesterton area. Upfront pricing is provided before work starts, and we can match or beat any local competitor’s price.

What most affects the final price:

• Home size and number of supply/return runs
• Access conditions (attic, crawlspace, finished areas)
• Material choice (flex vs. metal) and required insulation/sealing level
• Add-ons like zoning, new returns, or IAQ upgrades (HEPA/UV)

Minor leaks or crushed sections often justify repair; widespread undersized or deteriorated ducts favor replacement. Schedule an in-home evaluation to receive a firm written estimate. <br/> Updated: 2026-04-01 <br/> Need help in Chesterton, IN? Call (219) 500-8902 or book online.
