Most homes should have their dryer vent professionally cleaned once a year. If you do laundry frequently, have pets, or notice longer drying times, more frequent cleanings may be recommended.

Lint buildup restricts airflow, which can cause your dryer to overheat and significantly increases the risk of fire. Cleaning the vent also helps your dryer run more efficiently and can extend its lifespan.

Common signs include clothes taking longer to dry, a burning smell while the dryer is running, excess lint behind the dryer, or the dryer feeling unusually hot during use.
