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

Air duct replacement cost for a typical home varies widely and is finalized only after an on‑site evaluation of duct size, layout, materials, and how easy the ducts are to access. The biggest cost driver is scope—replacing an entire trunk-and-branch system versus a few failed runs often becomes clear after airflow testing and inspection.

Many homes don’t need full replacement; sealing or targeted repairs can fix comfort and airflow issues, and our inside‑out Sky Seal process measures leak reduction in real time and provides a certification of results. Our technicians regularly complete duct projects across the Portland area, including Boring homes.

If you’re comparing budgets, look for these factors that change price:

• Full-system replacement vs. section-only work
• Material choice (flex vs. metal) and added insulation
• Crawlspace/attic access complexity and total run length
• Upgrades like upsizing, zoning, antimicrobial blue ductwork, or IAQ add‑ons

Schedule an in‑home evaluation to confirm scope, options, and a written estimate before you commit.
