How this air duct cleaning cost calculator works
The estimate starts from whichever is larger — your vent count × $35 or your square footage × $0.18 — then multiplies by the number of HVAC systems in your home. Homes with more registers or more air handlers take longer to clean, so both factors push the price up. Add-ons like dryer vent cleaning, mold remediation, and sanitizing fog are layered on top.
What affects your real duct cleaning price
National averages run roughly $450–$1,000, but your actual quote depends on duct accessibility, contamination level, ductwork material, and regional labor rates. Mold or heavy debris can add 50% or more, and a separate dryer vent costs around $100–$150. Always compare a few licensed, NADCA-certified providers and beware of suspiciously cheap “$79 whole-home” coupons that turn into upsells.
