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 by Ultimate Heating & Air, Inc, because price depends on the home’s layout and project scope. The biggest swing usually comes from total duct length and how accessible the attic, crawlspace, or basement is. In older homes, reusing existing chases can trim labor, while tight spaces often add hours. We replace ductwork across the Boise metro and in nearby Kuna every week, matching ducts to the system for proper airflow.

Key factors that change the price:

• Home size and linear footage of duct runs
• Number of supply and return branches per room
• Material selection and required insulation or sealing level
• Access limits and any design corrections to fix airflow issues

Replacement proposals are free, and financing is available with payments as low as $107 per month (on approved credit). Schedule a free in‑home proposal to get a firm, written price and options.
