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

Air duct replacement cost for a typical home varies widely and is only confirmed after an on‑site inspection. The biggest drivers are system size, duct length and material, access to attics/crawl spaces, and whether the design needs changes for proper airflow and sealing. Many homes don’t need a full tear‑out; targeted repairs or sectional replacement often solve comfort and efficiency issues. A technician’s pressure and leakage tests guide the decision, and we often find the plenum-to-trunk transition leaks more than the straight runs. Our team handles these projects across the Denver metro, including homes near Castle Rock.

Consider full replacement when you see any of the following:

• Undersized, crushed, or badly kinked runs restricting airflow
• Widespread joint leaks that persist after sealing attempts
• Heavy corrosion or fiber breakdown across multiple sections
• Layout changes (additions, finished basements) needing new supply/return paths

We offer a $69 Air Duct Repair Assessment with same‑day availability, and VIP Members get the diagnostic free. Final pricing is confirmed after an on‑site evaluation with written options.
