How to Choose a Dryer Vent Cleaning Company

Why this trade attracts shady operators

Dryer vent cleaning is unlicensed in New Jersey. Anyone with a brush kit, a vacuum and a pickup truck can advertise the service. Most homeowners don't know what a real cleaning looks like, can't easily verify whether the work was done properly, and only call when there's a problem — which makes the customer easy to upsell. The result is a trade where reputable operators and "$59 cleaning" coupon mailers compete for the same eyeballs, and the coupon mailers often win.

The good news is that you can filter the field down to legitimate operators with a handful of basic questions before you ever schedule a visit.

Questions to ask before booking

1. "Are you fully licensed and insured?" The operator should be able to immediately tell you what insurance they carry — general liability at minimum, ideally with a million-dollar limit — and offer a Certificate of Insurance on request. If they can't or won't provide a COI, walk away. Especially important for HOAs, condos and any commercial property.
2. "Do you give flat-rate quotes over the phone?" A reputable operator can quote a typical home over the phone with a couple of questions about run length, termination type and dryer location. If the only answer is "we'll tell you when we get there," that's a sign the price is going to be whatever they think they can get.
3. "What's included in the price?" A real cleaning includes the full mechanical brushing of the run, HEPA vacuum extraction, exterior cap servicing, anemometer airflow verification, photos and a written invoice. If the price is suspiciously low ($59, $79, $99 for a "full cleaning"), it's bait pricing — the actual quote will more than triple once they're on site.
4. "Will you measure airflow before and after?" This is the diagnostic question. Operators who don't carry an anemometer don't have a way to verify the cleaning was successful — which means they're going to tell you it was successful regardless. Anyone serious in this trade has the tool and uses it.
5. "What happens if you find something a cleaning can't fix?" The right answer is: we stop, document the problem on camera, walk you through what we found, and give you a separate written quote for the next step. The wrong answer is silence or vague upsell language.
6. "Do you provide a written certification or invoice?" Important for insurance, HOA records, pre-listing due diligence, and your own records. Should be standard.

Red flags

• Coupon-mailer pricing under $100. Almost always bait pricing. The crew arrives, finds problems, and the actual bill ends up at $300-$500.
• "Special equipment fee" or "additional service fee" added on site. If a fee wasn't disclosed when you booked, push back hard. Reputable operators quote everything in advance.
• Aggressive upselling for repairs. If every cleaning visit somehow surfaces $400-$800 of urgent repairs, that's a pattern, not coincidence. A second opinion costs nothing.
• "We can't measure airflow because…" there's never a real reason. They don't have the tool.
• No COI available, or insurance "we'll send it later." Should be a same-day deliverable from any legitimate operator.
• Pressure to commit to repairs on the spot. Real problems will still be problems tomorrow. Reputable operators give you written quotes you can take to a second opinion.
• Reviews that all read like marketing copy. Skim a company's Google reviews. Real reviews mention specifics — the technician's name, what was found, what neighborhood. Fake reviews are vague and superlative.
• Out-of-area phone numbers or 800 numbers with no local presence. National-brand-style "dryer vent cleaning" services often dispatch to subcontractors with no accountability and no local reputation to protect.

Green flags

• Local phone number, local presence, identifiable owner.
• Years in business and a track record you can verify with a Google search of the business name plus owner name.
• Reviews that mention specific neighborhoods (Estate Section, Upper Montclair, Watsessing, the Ironbound) — a sign the reviewers are real local customers.
• Honest pricing structure that matches what other reputable operators in the area charge.
• Willingness to put quotes in writing and email a COI before the appointment.
• An owner who answers the phone or returns your call promptly.
• Photo documentation as standard practice, not an upsell.

What a fair price actually looks like

For most North Jersey single-family homes, a complete cleaning is $149-$249 depending on run length, elbows and termination type. Anything materially below that is bait pricing. Anything materially above that — particularly without a clear explanation of why your home is unusual — is overpriced. See our pricing guide for the full breakdown.

How to verify after the fact

If you've already had a cleaning done and want to know whether it was real, ask yourself:

• Did the technician spend at least 45 minutes on the job?
• Did they show you actual lint that came out of the vent?
• Did they measure airflow at the exterior cap?
• Did they provide before-and-after photos?
• Has cycle time on your dryer noticeably improved since the visit?

"No" to two or more of those — especially the cycle-time question — and you may not have actually gotten a cleaning. A second opinion from a different operator is cheap insurance.
