Dryer exhaust safety
Dryer Vent Cleaning
Lint buildup is a leading cause of residential dryer fires. Our CSIA Certified Dryer Exhaust Technicians clear the full vent run — from the dryer to the outside termination.
A clogged dryer vent does two things: it makes your dryer work harder (longer cycles, higher bills, worn-out machines) and it traps hot, lint-laden air in a run that was designed to exhaust it. That's how dryer fires start.
Superior's technicians hold the CSIA Certified Dryer Exhaust Technician credential — the industry standard for dryer venting — and clean the entire run, not just the first few feet behind the machine.
What's included
Full-run cleaning
From the dryer connection through walls, ceilings, and roof or sidewall terminations — the whole vent, not a partial pass.
Exhaust inspection
We verify airflow at the termination and check the run for crushed, disconnected, or improper venting.

The full run is clear from the dryer connection to the exterior hood. Air (and lint) exits freely; clothes dry in a single cycle.

2 The film builds ~Year 1
The lint screen only catches about half the lint — the rest sticks to the duct walls, especially at elbows and joints. You won't see it from either end.

3 Restriction Years 2–3
Moist air lingers, so lint packs faster. Loads need a second cycle, the laundry room heats up, and the exterior damper barely opens.

4 Fire territory Neglected
Trapped heat meets packed fuel. This is how roughly 2,900 U.S. dryer fires start every year — and “failure to clean” is the leading factor. Annual cleaning resets the whole timeline.
The fix is boring and cheap: an annual professional cleaning of the full run. Test your vent's airflow at home first
Warning signs your dryer vent is clogged
If any of these sound familiar, have the vent cleaned before you run another load:
- Clothes take more than one cycle to dry
- The dryer or the laundry room gets noticeably hot
- A burning or musty smell while the dryer runs
- Little or no airflow at the outside vent flap
- Lint collecting around the door seal or behind the machine
How often should dryer vents be cleaned?
Once a year is the standard guidance for a typical household — more often for long vent runs, big families, or pet-heavy homes. Many customers pair an annual dryer vent cleaning with a duct inspection so both systems get checked in one visit.
Dryer Vent Cleaning FAQs
Is a dirty dryer vent really dangerous?
Yes. Lint is highly flammable, and lint buildup is a leading cause of residential dryer fires. A clear vent also lets the dryer exhaust moisture properly, so clothes dry in one cycle.
How long does dryer vent cleaning take?
Usually under an hour for a typical home, depending on the length and routing of the vent run.
Can you do it with my duct cleaning?
Absolutely — pairing the two is the most popular way to book, and we run promotions for combining them. Ask when you call.
