Often, yes. The FTC and NADCA have both published warnings about bait-and-switch duct-cleaning offers: a teaser price gets the truck in your driveway, and on-site "findings" — or a cleaning that never really happens — make up the difference. Here's how to recognize the play.
How does the $99 bait-and-switch actually work?
The coupon is priced below what an honest cleaning can cost — the national average is about $389, and NADCA-standard whole-system jobs typically run $450–$1,000 (see the full cost guide). So the operator has two ways to make the visit profitable: escalate (discover "mold," add per-vent fees, declare your system oversized) or evaporate (run a shop-vac over the registers for 45 minutes and leave the duct runs untouched). Either way, you don't get what you thought you bought.
What are the red flags to watch for?
A price that can't cover the work
A whole-house cleaning for $99 when the national average is ~$389 and NADCA-standard jobs run $450–$1,000. The gap gets closed in your living room, not theirs.
“Findings” minutes after arrival
Sudden mold discoveries, per-vent surcharges, or “your system is bigger than the coupon covers.” Real problems come with photo evidence you can verify.
No equipment on the truck
A shop-vac and a spinning brush can't create the negative pressure source removal requires. If there's no truck-mounted or comparable vacuum system, it's a dusting, not a cleaning.
No published standard or membership
NADCA members clean to the documented ACR standard and are listed in a public directory you can check. “Certified” with no certifier named means nothing.
No proof of work
If the company doesn't photograph the inside of your ducts before and after, you're taking the whole job on faith.
Pressure to decide right now
Today-only pricing and scare language exist to prevent exactly one thing: a second opinion.
What does the honest version look like?
An upfront price quoted before the truck rolls — and invoiced unchanged. Truck-mounted vacuum equipment creating real negative pressure. Both supply and return sides cleaned, trunks included. A NADCA membership you can verify in the public directory. And photographic proof: we shoot the inside of your ductwork before and after on every single job, which is why "showed us the photos" is the most repeated line in our 4.9★ Google reviews.
