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

Air duct replacement cost for a typical home is determined after an on‑site inspection because price varies with duct layout, material choice, and how hard the ducts are to access. The biggest swing usually comes from labor to reach attics or crawlspaces and to adapt new ducts to existing equipment. We replace ducts with a mechanical, code‑conscious approach and verify airflow after install; in our experience around the Treasure Valley, homes with older additions or tight crawlspaces take more time. If your current ducts are simply dirty, cleaning is a different service and is priced separately. Free estimates and second opinions are available for major repairs.

What most affects price:

• Total duct length and number of runs
• Material and insulation (flex, metal, R‑value)
• Access conditions (attic, crawlspace, finished ceilings)
• Added scope like new returns, sealing, or balancing
