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

Air duct replacement cost varies by home and is confirmed only after an on-site inspection. The biggest driver is how much ductwork must be replaced and how accessible it is; material choice and design changes also affect price. Many homes only need targeted section replacement or leak sealing, not a full swap. If airflow is uneven or ducts are undersized, redesigning trunk lines can cost more but solves the root issue. We regularly handle replacements in the Ossian area and provide upfront pricing so you agree to the price before work starts.

Key cost drivers to review during an estimate:

• Total length and number of runs
• Attic/crawlspace access and labor time
• Material (flex, fiberglass-lined, or rigid metal)
• Needed redesign, balancing, or code updates
