High-use dryers need closer attention
Large households, rentals, salons, laundromats, and shared laundry rooms may run far more cycles than a lightly used residential dryer.
Long routes can collect more lint
Upper-floor, roof-vented, and interior-room dryers may have longer ducts with more turns, affecting airflow and service access.
Use findings to set the interval
A provider who sees the vent and lint accumulation can recommend a more useful interval than a generic calendar rule.
Common questions
Before you request help
Is once a year always enough?
Not necessarily. Some systems need more frequent attention and others accumulate lint more slowly.
Does cleaning the lint screen replace vent cleaning?
No. Some lint travels beyond the screen into the duct.
