Ductwork Replacement Cost Calculator
2026 U.S. ductwork replacement planning ranges scale with conditioned area served and scope (partial runs, mains, whole-home redesign). Sealing-only jobs belong in duct repair; full redesign often pairs with HVAC equipment replacement. Replacing crushed, undersized, or leaky duct systems to restore airflow. Access in attics and crawl spaces dominates labor more than sheet-metal material alone.

Methodology & estimate disclaimer
2026 U.S. ductwork replacement planning ranges scale with conditioned area served and scope (partial runs, mains, whole-home redesign). Sealing-only jobs belong in duct repair; full redesign often pairs with HVAC equipment replacement.
Actual costs vary by location, home condition, material availability, permits, and project complexity. Read our methodology, the national cost bands table, editorial policy, and disclaimer. Planning provenance uses internal model notes (not invented third-party citations)—see the bands page for published low/typical/high frames.
