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

Air duct replacement cost for a typical home depends on your system’s size, layout, and duct materials, and Russett Southwest confirms final pricing only after an on‑site evaluation. Most of the cost is labor to remove old ducts and install new, properly sized and sealed runs so airflow and comfort are restored. In our Green Valley service area, our process includes a comprehensive report and personalized options so you can choose repair, partial replacement, or full replacement as needed. Financing is available, with air duct replacement options advertised as low as $80 per month.

Common factors that change the price:

• Total duct length and number of supply/return runs
• Material type (flex, sheet metal) and insulation needs
• Access to attics, crawlspaces, or tight chases
• Required sealing, balancing, and register/boot updates

If your ducts are damaged, undersized, or leaking heavily, replacement is often more cost‑effective than repeated patch repairs; schedule an in‑home assessment to get a precise quote. <br/> Updated: 2026-04-03 <br/> Need help in Green Valley, AZ? Call 520-200-5869 or book online.
