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

Air duct replacement cost for a typical home is set after an on-site inspection because layout and access control the price. Most of the cost is labor to remove old ducts and fit new, properly sized, sealed runs. Often, replacing sections or sealing leaks restores comfort for less than a full changeout. After a system map and airflow checks, we give flat-rate, upfront pricing. Our team frequently handles these projects in the Franklin area.

Key price drivers include:

• Home size and number of runs
• Attic, crawl, or basement access limits
• Duct material choice and insulation
• Added returns or code updates
