What affects the cost
Several factors influence the price you’re quoted for duct cleaning:
- Home & system size. Larger homes with more ductwork and multiple HVAC systems cost more to clean.
- Number of vents. Many companies price per vent ($25–$50), so vent count drives the total.
- Accessibility & condition. Hard-to-reach ducts or heavy dust, mold, or rodent debris increase labor.
- Add-on services. Sanitizing, dryer-vent cleaning, and new filters add to the base price.
- Local labor rates. Service labor tracks the area cost of living, so prices vary by region.

When duct cleaning is worth it
The EPA suggests cleaning when there's visible mold, vermin infestation, or excessive dust and debris clogging the registers. After a renovation, or if anyone in the home has allergies, a cleaning can also help indoor air quality.
Avoiding lowball scams
Extremely cheap "$59 whole-house" offers are a classic bait-and-switch — the crew arrives and upsells "mandatory" sanitizing or mold treatment. Choose a NADCA-certified company, get the price in writing, and confirm exactly which ducts and vents are included.
