How much does ductwork replacement typically cost for homeowners?

We don’t post flat pricing for ductwork replacement. A Harker technician will inspect your system and provide a written quote based on findings. Cost varies by home size, duct material, attic or crawlspace access, presence of mold, and whether it’s a partial repair or full replacement in Madison and nearby areas.

• Schedule an inspection; we use specialized tools to assess ducts and components.
• Review any moisture or mold issues; remediation may be needed before work.
• Compare options like IAQ upgrades or ductless alternatives.

"My Harker furnace install team was great... I had duct work done, too, and they did a great job and cleaned up any mess created by the work." — Susan H.
