Air Duct Cleaning Scams to Avoid ($99 Blow-and-Go)

Consumer Protection

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.

How to protect yourself from a duct cleaning scam

The most common scam is the “blow-and-go”: a company advertises a whole-house cleaning for a very low price, then either does a few minutes of token work or uses high-pressure tactics to upsell “mold treatment,” “sanitizing,” or extra vents once they’re in your home. The Federal Trade Commission and state consumer agencies have warned about these bait-and-switch offers for years.

Questions to ask before you book

  • What exactly does the quoted price include, and how many vents?
  • Will you show me before-and-after photos of my ducts?
  • What equipment do you use, and is the work itemized?
  • Are you local, insured, and able to provide references?

A trustworthy company gives you an itemized quote, documents the work, and never diagnoses “dangerous mold” sight-unseen over the phone. If pricing seems too good to be true, it usually is.

We believe in transparent, itemized pricing and photo documentation. See how to choose a company or get a quote with no pressure.

Frequently asked questions

How can I tell if an air duct cleaning company is legitimate?

A legitimate company gives you an itemized written quote tied to your actual vent count, shows before-and-after photos of your ducts, and never diagnoses “toxic mold” sight-unseen over the phone. Ask whether they are local, insured, and able to provide references.

Is a $99 whole-house air duct cleaning a scam?

Extremely low flat prices are the classic “blow-and-go” setup: the advertised rate covers only token work, and the real money comes from high-pressure upsells once the crew is inside your home. A realistic quote reflects the number of vents and the condition of your system.
