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

We don’t list a flat price for full ductwork replacement. Actual cost is confirmed after an on‑site inspection by a Harker technician. Pricing depends on home size, duct length and access, material (e.g., sheet metal), needed sealing/balancing, and any moisture or mold issues. Our Madison-area team uses specialized tools to inspect hidden sections and will show you any problems. If ducts are sound and no allergies or mold are present, replacement may be unnecessary; cleaning or IAQ upgrades could be enough. $500 off Mitsubishi ductless installs is available.
