Choosing a duct cleaner comes down to six verifiable checks: NADCA membership, real vacuum equipment, photo proof of work, licensing and insurance, an honest review history, and an upfront price that covers the whole system. Any company worth hiring passes all six — happily.
What should you check before booking?
Verifiable NADCA membership
Look the company up in NADCA's public directory. Members clean to the published ACR standard — 'certified' with no certifier named is a marketing word, not a credential.
Equipment that can do the job
Source removal needs strong negative pressure. Ask what's on the truck: a truck-mounted vacuum (we run Pringle rigs) moves several times the air of a portable unit. A shop-vac is a red flag.
Proof of work — before/after photos
The single best filter. A company that photographs the inside of your ducts on every job has nothing to hide; one that won't is asking you to take the job on faith.
Licensed, insured, background-checked
These people work inside your home. Ask for proof of insurance and whether techs are background-checked — and expect a comfortable yes.
A real, local review history
Read recent Google reviews for specifics — punctuality, photos shown, price honored — not just the star number. Volume plus detail beats a perfect score with 12 reviews.
An upfront, complete price
Both supply and return sides, trunk lines, vent count, and add-ons itemized before work begins. The number quoted should be the number invoiced — no on-site 'findings' arithmetic.
When does the choice matter most?
The older and dirtier the system, the wider the gap between a real cleaning and a cosmetic one. Greater Cleveland's housing stock — median Cuyahoga County home built in 1957 — is exactly where under-equipped crews fall short, because six decades of accumulation doesn't come out with a brush and a plug-in vacuum. If that's your house, read why old Cleveland homes need more before you compare quotes.
What are the failure modes if you skip the checks?
Two, mostly. You overpay a scare-based upseller — the $99 coupon playbook — or you pay a fair price for an unfair job: half the system cleaned, no documentation, and dust back in a week. Both end the same way: the actual problem is still in your ducts. Cost expectations help here too — know the honest price range before anyone quotes you.
