Air Duct Cleaning Scam Warning: Bait-and-Switch Red Flags
Air duct cleaning scam warning signs include an unusually low whole-home teaser, undefined system scope, pressure tactics, and unapproved add-ons.
The short answer
An unusually low whole-home air duct cleaning teaser does not tell you which HVAC system, supply registers, returns, equipment, cleaning method, or documentation is included. The safest comparison is a written property-specific scope, not the smallest headline number.

What makes a low headline offer risky?
A teaser can cover only a few openings, a quick surface treatment, or an inspection that becomes an aggressive sales visit. The advertisement may omit the number of HVAC systems, return ducts, main trunks, access points, labor, or equipment needed for source removal.
A low advertisement is not proof of fraud by itself. The warning sign is an incomplete scope combined with pressure to approve expensive work after the technician enters the home.
Questions to ask before allowing work
Ask the company to identify the HVAC unit, included supply registers and returns, cleaning method, equipment, access requirements, documentation, and conditions that could require additional approval. Keep the answer in writing.
- How many HVAC systems and openings does the quote include?
- Is the work source removal, surface cleaning, or inspection only?
- What equipment will be connected to the system?
- Can any additional charge begin without written customer approval?
- What happens if damaged ductwork, moisture, or suspected mold is found?
How AirDuctVet confirms scope
AirDuctVet prepares a free quote from the property type, HVAC unit count, accessible vents and returns, equipment location, recent construction, visible condition, and access details. Routine HEPA negative-air source removal is separated from extensive vent-by-vent work.
Extensive cleaning is quoted separately when the condition requires it, and no additional work begins without customer approval. Sanitizing is an optional add-on used only when appropriate and separately approved.
How to compare companies fairly
Compare insurance, business identity, recent reviews, equipment, written limitations, warranty terms, and the exact included system—not only the advertised number. A clear company should explain what cleaning cannot repair and when another HVAC, mold, restoration, appliance, or construction professional is needed.
