How to Choose an Air Duct Cleaning Company in NJ

The duct cleaning industry has a real scam problem. Here are the questions to ask, the red flags to spot, and how to make sure you get an honest job — not a $79 bait-and-switch.

The duct cleaning industry has a real reputation problem — and it's mostly self-inflicted. Spend ten minutes online and you'll see ads for "$79 whole home duct cleaning!" Those ads are almost always a setup for a bait-and-switch that ends with you paying $1,500+ for half a job.

Here's how to vet a real one — the questions to ask, what to demand, and what red flags should make you hang up immediately.

The 6 questions to ask before booking

1. "What certifications and insurance do you carry?"

Look for recognized industry credentials (such as CSIA, NCSG or NADCA) plus proof of liability insurance and a NJ contractor registration.

2. "What exactly is included in the price you quoted?"

Get this in writing. A complete cleaning includes:

If the quote is "by the vent" — make sure both supplies AND returns are counted.

3. "How long will it take?"

A proper residential cleaning takes 3–5 hours for a typical home. If they say "30 minutes" or "an hour" — they're not actually cleaning anything. They're running a vacuum at one register and calling it done.

4. "Do you use negative pressure containment?"

The right answer is yes. The technician should hook a powerful HEPA vacuum to the main trunk line, then agitate each branch run with a rotating brush. The negative pressure pulls everything into the vacuum instead of blowing dust through your home.

5. "Are you licensed, bonded, and insured?"

Ask for proof of general liability insurance and worker's compensation. A real company emails it without hesitation. A scam operation gets cagey.

6. "Do you guarantee no upcharges on site?"

This is the bait-and-switch test. A scammer will say "well, it depends what we find." An honest contractor will give you a firm price contingent only on accurate vent counts — not on suddenly "discovering" mold or extra work.

5 red flags to walk away from

  1. Robocalls or door-to-door sales. Legitimate companies don't operate this way.
  2. Prices under $150 for a whole-home cleaning. It's bait — the real bill is always 5–10x higher.
  3. "Free inspection" that always finds mold. Real mold testing requires lab analysis, not a flashlight.
  4. No physical address or only a cell number. A real business has a verifiable location.
  5. Pressure to sign on the spot. An honest contractor lets you think about it.

Frequently Asked Questions

Why are some duct cleaning prices so low?

Ads for $79 or $99 'whole home duct cleaning' are almost always bait-and-switch. Once on site, the technician finds 'mold,' 'mildew,' or 'extra vents' and quotes $800–$2,000 for the actual work. At Green Care, a full cleaning is $290 for up to 10 vents, plus $25 per additional vent.

What certifications should an air duct cleaner have?

Look for recognized industry credentials (such as CSIA, NCSG or NADCA) plus proof of liability insurance and a NJ contractor registration.

Should duct cleaning include the air handler and coil?

Yes. A complete cleaning covers all supply and return ducts, the air handler/blower compartment, the blower wheel, and the evaporator coil. Cleaning just the ducts and leaving the air handler dirty re-contaminates the system within weeks.

How long should a real duct cleaning take?

A proper residential duct cleaning takes 3–5 hours for a typical home, depending on system size and vent count. If a company says they can be in and out in 45 minutes, they're not actually cleaning the system.
