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 in-home inspection. The main cost driver is scope: complete replacement versus targeted sections, since some issues can be solved with repair or professional cleaning. We regularly service ductwork for homeowners in the Peru area. Before any work, you’ll receive a written, free estimate, and eligible duct services include a one-year parts-and-labor warranty. A seasoned tech may also recommend minor layout changes when tight spaces restrict airflow, which can affect price. If leakage is limited, sealing or sectional repair is often more cost-effective than full replacement.

Your quote typically reflects:

• Total length and number of supply/return runs
• Duct material and required fittings (flex vs metal, plenums, boots)
• Access conditions in attics, crawlspaces, or chases
• Added work such as insulation, air sealing, new returns, or airflow balancing

Schedule an in-home evaluation to get a firm price and plan tailored to your duct system.
