How much does professional air duct cleaning service cost?

Professional air duct cleaning cost is confirmed only after an on-site inspection because price depends on your system and home layout. The biggest driver is system size, followed by how dirty or contaminated the ductwork is. Access matters too: long attic runs, tight crawlspaces, or sealed chases add labor time. In the Christmas area, homes with older flex duct and attic-only access often require more setup and cleanup, which affects the quote. A thorough contractor should price the whole job (not just “per vent”), include main trunks and the air handler section, and only recommend sanitizing when justified. If duct walls are damaged or collapsed, repair or replace those sections instead of cleaning.

Expect your quote to reflect these specifics:

• Total number of vents/returns and overall duct length
• Contamination level (heavy dust, renovation debris, pest waste, or suspected microbial growth)
• Accessibility (attic or crawlspace only, multi-story runs, insulation to move)
• Add-ons such as coil/blower cleaning, sanitizer, or sealing after leaks are found
