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

Air duct replacement for a typical home is priced only after an in-home assessment; we give upfront, itemized pricing once we map your duct layout. The main cost driver is how much duct must be replaced. If ducts are loose, leaky, or under-insulated, targeted repair or redesign is often more cost-effective; full replacement is best for severe damage or poor design. Work is backed by a 2-year parts and labor warranty, extendable to 3 years with our club membership. We handle replacements in the Hampstead area regularly, so our estimates reflect local home layouts. A smart tweak to a few runs can quiet rooms more than replacing every trunk.

Your quote typically reflects:

• Total duct length and branches.
• Material and insulation choice.
• Access and labor difficulty.
• Sealing, balancing, or high-velocity needs.

Schedule an in-home evaluation to get a firm, itemized quote and to verify whether repair or full replacement is the smarter move.
