How much does it cost to replace ductwork in a typical home?

Ductwork replacement costs vary by home and require an on-site assessment for an exact price. We provide upfront, itemized pricing after inspection in Bellingham, MA and nearby. Costs depend on home size, duct length, access (attic, crawlspace, finished ceilings), material choice, code updates, and whether it’s a full or partial replacement. Many homes can consider duct sealing or cleaning first, which can improve comfort and reduce energy use by up to 20%. Every replacement includes a 2-year warranty, or 4 years for Priority Plan members.
