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

The cost to replace ductwork varies by home and is confirmed after an on-site assessment. Pricing depends on duct length, material (flex or metal), access (attic/crawlspace), needed repairs, insulation, and sealing. CM Heating provides affordable, upfront pricing after a thorough ductwork evaluation in areas like Everett and Lynnwood. If full replacement isn’t required, we can also quote non-invasive Aeroseal sealing with a free estimate.

Quick steps:

  • Schedule a duct assessment.
  • Review options: replacement vs. sealing/cleaning.
  • Approve the written estimate and any financing options.
