Professional duct cleaning clears dust, debris and allergens from your HVAC ductwork. Price tracks the number of vents and systems, plus how dirty or moldy the ducts are. Beware too-good-to-be-true coupon offers — reputable companies price by the system, not $99 whole-home specials.

Air duct cleaning cost — frequently asked questions
How much does air duct cleaning cost?
Air duct cleaning runs about $250–$1,000 for an average home, around $400 typical for a single system. Mold remediation inside ducts or very large homes cost more. Be wary of $99 whole-house offers — they're usually bait for upsells.
Is air duct cleaning worth it?
It's most worth it after renovations, visible mold, pest infestations, or if vents blow visible dust. NADCA recommends cleaning every 3–5 years; homes with allergies or pets often benefit sooner.
