Air Duct Cleaning Cost

Air duct cleaning costs $340 to $430 for a typical home with 10 to 20 vents and one HVAC system, before your ZIP code is applied. Vent count is the primary driver, and NADCA, the National Air Duct Cleaners Association, cites a broader typical range of $450 to $1,000 across home sizes and providers.

Cost factors

What changes the price

Number of vents
The primary driver for a residential job, since more vents mean more ductwork runs to access and clean.
Number of HVAC systems
Each additional system beyond the first adds $72 to $92, since a second system means a fully separate set of ductwork and equipment access.
Suspected mold
Adds about 45%, since mold in ductwork requires specialized containment and treatment, and often an inspection before work can even start.
Commercial vs. residential
Commercial jobs are priced per square foot instead of by vent count, reflecting the larger and more variable duct systems in commercial buildings.
Add-ons
UV sanitizing, a dryer vent bundle, coil cleaning, and filter replacement are priced separately and shown as their own line.
Frequently asked

Questions people ask before booking

How much does air duct cleaning cost?

For a typical home with 10 to 20 vents and one HVAC system, cost runs $340 to $430. NADCA, the National Air Duct Cleaners Association, cites a broader typical range of $450 to $1,000 across home sizes and service providers.

How often should air ducts be cleaned?

NADCA recommends every 3 to 5 years for most homes, sooner for homes with pets, smokers, allergy sufferers, or recent renovations. The EPA takes a more conservative view, recommending cleaning only when there is visible mold, pest infestation, or heavy dust release, not on a fixed schedule.

Does mold in the ductwork change the price?

Yes, by about 45%. Suspected mold requires specialized containment and treatment procedures, and often an inspection first, all of which adds real cost beyond a standard cleaning.

Is air duct cleaning priced differently for a commercial building?

Yes. Commercial jobs are priced per square foot rather than by vent count, since commercial duct systems vary too widely in layout and length for a simple vent-count model to work well.

Does having more than one HVAC system cost more to clean?

Yes, $72 to $92 more per additional system beyond the first, since each system has its own separate ductwork that needs full access and cleaning.

Unless you have a specific reason, visible mold, pests, or a recent renovation, there is no urgent need to clean on a fixed schedule. Use NADCA's 3 to 5 year window as a reasonable default and let actual conditions move that timeline up if needed.
