Which of the following is true regarding dryer vent maintenance?

Regular cleaning of dryer vents is essential for maintaining proper airflow and preventing safety hazards such as fires. Lint and debris accumulate in the vent over time, which can restrict airflow, leading to inefficient operation of the dryer and potential overheating. By cleaning the dryer vents regularly, homeowners can ensure the dryer operates efficiently, extending its lifespan and reducing energy bills. Regular maintenance also helps decrease the risk of lint fires, a significant danger associated with laundry appliances.

In contrast, other options suggest inadequate practices that could lead to issues. Believing that dryer vents never need cleaning overlooks the accumulation of lint and the inherent risks. The idea that they can operate without maintenance dismisses the critical safety and efficiency concerns. Cleaning only when clogged is a reactive approach that increases the chance of problems arising before the next cleaning occurs. Therefore, the practice of regular cleaning is crucial for overall dryer performance and safety.
