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

Air duct replacement cost for a typical home varies and is only confirmed after an on-site inspection. The biggest swing is usually home size and the total length and layout of the duct runs that must be replaced. Replacement is worth considering when ducts are collapsed, rusted, contaminated, or badly undersized; otherwise targeted repair or sealing may be more practical. We service homes throughout the west Indy area, so we’re familiar with older layouts that can affect labor time. A real-world technician note: long, tight attic or crawlspace access often adds more labor cost than the duct material itself. After evaluation, we provide clear, up-front pricing and a written estimate, with financing options available when needed.

Key factors that drive price:

• Total duct length, number of branches, and register count
• Material choice (flex vs. metal) and required insulation level
• Access conditions in attics, basements, or crawlspaces
• Code items and add-ons like new plenums, boots, or balancing dampers
