The answer to 'dryer vent cleaning frequency' is that most experts recommend cleaning your dryer vent at least once a year. Dryer vents can become clogged with lint over time, which can reduce airflow, increase drying times, and even pose a fire hazard. Regular cleaning helps maintain the efficiency and safety of your dryer.
The exact frequency may vary depending on factors like the size of your household, how often you use the dryer, and the length and configuration of your vent. Homes with larger families or frequent dryer use may need to clean the vent more often, such as every 6-12 months. Additionally, if you notice your dryer taking longer to dry clothes or the vent exhaust airflow seems reduced, it's a good idea to have the vent inspected and cleaned.
