The short answer
They are two different services, on two different systems, and neither one includes the other.
A dryer vent is a single exhaust duct. It carries hot, damp air and lint from one appliance to an outside wall or roof. Air ducts are the supply and return network that moves heated and cooled air through the whole house. Cleaning one does nothing for the other.
If you take one line from this page, take this one: clothes drying slowly is a dryer vent problem, and dusty registers are a duct problem.
VANTOR’s air duct cleaning scope says so directly. Dryer vent cleaning sits in that service’s exclusion list, next to HVAC equipment repair and duct sealing. It is a separate job with a separate scope, not an add-on somebody forgot to mention.
What dryer vent cleaning covers
The work follows the vent run from the back of the dryer to the point where it leaves the building.
A dryer vent cleaning visit reviews the accessible vent route and the exterior termination, removes accessible lint and debris within the approved scope, uses interior or exterior access depending on how the run is built, and finishes with an airflow check. If the dryer has to move to reach the interior connection, it gets moved and reconnected.
Basic dryer vent cleaning in Boise and the Treasure Valley starts at $69. What pushes a job past that is almost always the vent run itself: its length, its bends, and how the termination is built. Access, configuration, and how much has built up all shape the final scope.
The exclusions matter as much as the inclusions. This service does not cover dryer appliance repair, rerouting or replacing the vent, electrical or gas-line work, or opening up enclosed sections that cannot be safely reached. If the real problem turns out to be the appliance rather than the duct, cleaning the duct will not fix it.
What air duct cleaning covers
Duct cleaning works on the ductwork your heating and cooling system pushes air through.
The visit reviews the accessible supply and return duct areas, cleans the accessible areas within the approved scope, cleans applicable vent covers and registers, and checks airflow afterward where that applies. Professional vacuums and cleaning or agitation heads do the work. A typical visit runs about one to two hours, though system size, access, and the approved scope all move that number.
Here too, the exclusions are the useful part. The service does not include HVAC equipment repair, duct sealing, rerouting or replacement, mold remediation, or work on sections nobody can reach. And it does not include the dryer vent.
That last exclusion is what sends most people to a page like this one. The two services are sold together often enough to read as a single product, and they are not.
Start from the symptom
Most people arrive at this question because of something they noticed, not because they were reading a service menu. Working backwards from the symptom is faster than reading two scopes and guessing.
Point toward the dryer vent when:
- Clothes take longer than usual to dry, or need a second cycle
- Airflow at the outside vent feels weak
- Lint is visible near the dryer connection or the exterior termination
- The vent run is long or turns several times
Point toward the ducts when:
- Dust or debris is visible at vents and registers
- Debris comes out of a vent when the system kicks on
- Accessible duct areas have visible buildup
- The house recently had construction or remodeling work
Two things are worth saying plainly here. A symptom on one list tells you nothing about the other system, so a dryer that dries fine is not evidence about your ducts. And neither list is a schedule. Both are observations about one house at one moment, which is the only sensible reason to book either service.
Why one company does both and still sends two different visits
It is a fair suspicion. If the same company cleans both, is the distinction anything more than a way to sell two jobs?
It is, because the work is not the same work. The dryer vent is a single-purpose exhaust line, usually reached from behind the appliance and from the exterior termination, and what accumulates in it is lint. A duct system has multiple supply and return branches, is reached through registers and access points, and what accumulates in it is household dust and construction debris. Different access, different equipment, different time on site.
Quoting them as one service would mean charging for work that was not done on one of the two systems. Keeping them separate is what makes the scope checkable, which is also what makes the price checkable.
What duct cleaning does not promise
This is where most writing on the subject stops being useful.
The usual framing is that clearing the dryer exhaust is a safety service and cleaning ducts is an air-quality service. The first half is a reasonable description of why lint removal matters. The second half is stated far more confidently across the web than the evidence supports.
The EPA’s own guidance is that ducts should be cleaned on an as-needed basis rather than on a routine schedule, because the benefits of duct cleaning remain uncertain. That comes from the agency people invoke when they talk about indoor air quality, and it almost never appears on a page selling the service.
That is why the signs listed above are all things you can see. Visible buildup, debris coming out of a register, a recent remodel: those are reasons. “It has been a few years” is not one, and VANTOR publishes no cleaning interval, because there is not an honest one to publish.
Booking both at once
Plenty of homes genuinely need both, and there is no reason to split that across two appointments.
If your symptoms point both ways, say so when you request service, and describe what you actually noticed: how long a load takes to dry, what the registers look like, whether anything comes out of a vent when the system starts. Two scopes get quoted, and they stay two scopes on the visit.
If only one list matches your house, book only that one. A duct cleaning will not shorten a drying cycle, and clearing the vent behind the dryer will not change what comes out of a register in the living room.
VANTOR provides both services across Boise and the Treasure Valley. Which one you need is a question about your house, not about the menu.
