Definition
The price you're comparing should describe the same service: negative-pressure, whole-system source removal covering every supply and return on the system — not a per-vent teaser that meters the house register by register.
What actually sets the price of a duct cleaning?
Four levers. System count is the biggest: a two-furnace colonial has two complete duct systems, roughly doubling the work. Then size and run count — every supply and return gets individually agitated and vacuumed, so a 28-vent two-story simply takes longer than a 12-vent ranch. Access is third: finished basements, tight chases, and duct runs buried in ceilings slow careful work. Condition is last: routine dust load cleans faster than post-remodel drywall debris or a pest cleanup with sanitation steps. A serious quote asks about all four before naming a number; a teaser quote asks for your credit card.
Why do we publish a flat $619 — and what does it include?
Because duct cleaning is the single most bait-and-switch-prone service in this trade, and a published flat price is the cleanest possible counter to it. $619 list covers the whole home on one system: every supply and return under negative pressure with mechanical agitation, the blower compartment, camera before-and-after, and an honest report of anything else we found in the tin. No arrival upsell, no 'contamination discovered' theater. Members of the On The Dot Club take 20% off that — one of the membership discounts that quietly banks back the annual dues.
Per-vent pricing vs. flat pricing: which protects you?
Per-vent pricing sounds precise and often is a funnel: the advertised per-vent number excludes returns, trunk lines, and the blower compartment — each an 'add-on' once the truck's in the driveway, which is how $18-a-vent becomes several hundred dollars of line items. Flat whole-home pricing puts the estimating risk on the contractor, where it belongs, and makes quotes actually comparable. If you do get per-vent quotes, force the comparison honestly: ask for the all-in number covering every supply, every return, and the air handler, in writing, before scheduling.
When should you not spend this money at all?
The same honesty applies in reverse: if a camera look shows normal light dust film, skip the cleaning and put the budget where it returns more — a media filter cabinet, a coil cleaning if the smell is at the AC, or simply nothing. Ducts don't need cleaning on a schedule; they need it on evidence. Our companion guide covers exactly when it's worth it; the annual duct video check that comes with membership is how you get the evidence without paying for a service call to obtain it.

Common questions
Is duct cleaning ever included in other work?
Yes — a whole-home duct cleaning ($619 value) is included free with a complete-system installation (furnace + AC, or a heat-pump conversion). If you're replacing equipment anyway, don't pay for cleaning separately — ask how the offers stack.
How long does the job take?
A typical single-system home takes a few hours done properly. Anyone quoting 45 minutes for a whole house is describing a different (and lesser) service, whatever they're calling it.
Does dryer-vent cleaning come with it?
It's a separate, shorter service with its own fire-safety justification. It's a sensible add-on while we're there — see our dryer-vent guide for why it earns its keep independently.
