The most common air duct cleaning scam is the “$99 whole-home” ad — a “blow-and-go” used to lure you in, then upsell hundreds of dollars in unnecessary add-ons on the spot. Other red flags include unsolicited robocalls, “free” inspections that always “find” mold, and scare tactics. Here’s how to spot and avoid them.

Air duct cleaning scams & red flags
- “$99 whole-home” pricing — a real source-removal cleaning takes hours and proper equipment; ultra-low rates are bait.
- Unsolicited calls/door knocks — reputable companies don’t cold-call about your ducts.
- On-the-spot “mold” discoveries with pressure to pay immediately for treatment.
- No inspection, no photos, no itemized scope.
- Cash-only / no license or insurance.
How to protect yourself
Ask for a written, itemized quote after an inspection; confirm the company is licensed, insured, and follows NADCA/EPA practices; and check real local reviews. The FTC and BBB both warn about low-ball duct-cleaning bait-and-switch schemes. See our honest take on whether the service is even needed: is air duct cleaning worth it? and how to choose a company.
