Air duct cleaning costs $300–$700 for a typical home. Learn when it's worth it, what to watch out for, and how to find a legitimate contractor.
Professional air duct cleaning costs $300–$700 for a typical single-family home with one HVAC system. Additional systems add $100–$200 each.
The EPA says you should clean your ducts only when necessary — not on a fixed schedule. Consider cleaning if:
✅ You see visible mold growth inside the ducts or on HVAC components
✅ There's evidence of rodent or pest infestation
✅ Ducts are clogged with excessive dust or debris
✅ You notice large amounts of dust on registers/vents
✅ You've recently completed a major renovation that generated drywall dust
✅ Someone in your household has unexplained allergy or respiratory symptoms
Don't be talked into cleaning "just because" — if none of the above apply, duct cleaning may be unnecessary.
Unfortunately, air duct cleaning is one of the most scam-prone home services. Common red flags:
🚩 $49 whole-house special — real duct cleaning cannot be done properly for $49. This is a common bait-and-switch tactic.
🚩 Pressure tactics — "We found mold! You need $2,000 of extra work right now."
🚩 No before/after photos — legitimate contractors document their findings.
🚩 Not using proper equipment — real duct cleaning requires truck-mounted or high-powered vacuum equipment.
