How Often Should You Clean a Dryer Vent?
Once a year is the standard starting point, but your actual household situation can reasonably shift that in either direction.
The Standard Recommendation
An annual cleaning is a reasonable default for most households, and lines up well with general home-maintenance seasonal checklists.
When You Might Need It More Often
A larger household doing frequent laundry loads, a longer or more bent vent run (common when the dryer isn't on an exterior wall), or a home with pets that shed heavily can all build up lint faster than average.
Signs You're Overdue, Regardless of Schedule
Slower drying times, a hot dryer or laundry room, or visible lint at the exterior vent hood are all reasons to move up the timeline rather than waiting for the calendar.
Why This Isn't Just About Convenience
Beyond drying time, lint buildup is a genuine fire risk — sticking to a reasonable cleaning schedule is a safety habit, not just a maintenance one.

Frequently Asked Questions
Does a shorter vent run need cleaning as often?
Generally less urgently than a long or bent run, but annual cleaning is still a reasonable habit regardless of vent length.
