How Often Should Your Household Clean Its Dryer Vent?

For a two-person household with a short run, once a year keeps the system within safe airflow.

That interval assumes rigid duct, a proper hood, and normal laundry volume.

Volume and duct geometry are the two multipliers. A family of five with a 25-foot run and three elbows is on a very different schedule than a couple venting through a rim joist.

Pet-heavy homes accumulate faster because fur binds into the lint layer.

• More than five loads per week
• Duct runs longer than 15 feet
• Two or more 90-degree elbows
• Shedding pets in the home
• Vertical or roof-terminated runs
• Any prior history of long dry times

If drying time increases noticeably, do not wait for the anniversary date. Airflow loss is progressive and accelerates.

A damper that stays shut while the dryer runs means the restriction is already severe.

We log the airflow reading at each visit, so year over year you can see whether the interval is right for your household or should be tightened.
