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

Air duct replacement pricing for a typical home is confirmed after an in-home evaluation because it varies by home size, duct design, materials, and access. Most cost swings come from how many runs and registers you have and how hard the ducts are to reach. We often repair or seal sections instead of full replacement when leakage or damage is limited, and we measure airflow and leakage before recommending a full swap. Our team handles this work routinely in the Carmel area and provides Pricing Upfront—you agree to the price before work starts.

Key factors that move the price up or down:

• Total linear feet and number of supply/return branches
• Material choice and insulation level (flex, sheet metal, or duct board)
• Access conditions and labor needs (attic, crawlspace, tight chases)
• Add-ons or scope changes like duct sealing, new registers, zoning, or IAQ upgrades
