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

Question

Accepted Answer

Air duct replacement cost for a typical home varies and is confirmed after an on-site inspection because layout, materials, and access drive the total. The biggest factor is how much ductwork must be replaced and how easy it is to reach in attics or crawlspaces. Our NATE-certified team handles full ductwork installation and replacement, and we provide upfront pricing with warranties on every job. Sometimes we find a targeted repair, sealing, or resizing fixes airflow issues without a full replacement. Our team regularly performs replacements throughout the Birmingham area, so we understand local home layouts and age-related duct issues. What most affects price: - Total length and number of runs being replaced - Duct type (flex, metal, or ductboard) and required insulation/sealing - Access conditions and structural obstacles - Needed repairs to plenums, boots, or registers Schedule a professional assessment to get an exact, itemized quote before work begins.
