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

Air duct replacement cost for a typical home is not a flat price and is confirmed after an on-site inspection. The biggest cost driver is how much duct must be removed and rebuilt versus sections that can be restored or sealed instead. Doc Dancer offers targeted repairs, Aeroseal leak sealing, and Duct Armor interior lining (authorized dealer) as cost-saving alternatives to full replacement, with upfront estimates. We routinely apply these options for homeowners in the Garrett area to avoid unnecessary tear-outs and disruption. In many older homes, replacing only crushed sections and then sealing the system restores airflow without opening ceilings.

To pin down pricing, a technician typically reviews:

• Total duct runs and number of supply/return vents
• Access limits (attic, crawlspace, or in-slab)
• Material and insulation choices
• Whether Duct Armor or Aeroseal can meet the performance goal
