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

Air duct replacement cost for a typical home is confirmed only after an in-home evaluation because pricing depends on the exact duct layout and scope. The largest cost driver is the size of the home and how much duct must be replaced or reconfigured. In many cases, comfort problems come from leaks or loose connections, where professional air duct sealing or targeted repairs can fix issues without a full replacement. We work across the Salem and Roanoke Valley area and provide transparent, fixed pricing once we assess your system.

Typical cost drivers our technicians measure:

• Access conditions (attic, crawlspace, or tight chases) that affect labor time
• Number of supply and return runs, and whether new plenums or boots are needed
• Material and finish choices, including insulation and the sealing level for efficiency

An on-site inspection is the only reliable way to set scope and give you an accurate written price.
