The answer to 'how to maintain dryer vent' is to regularly clean and inspect your dryer vent to ensure proper airflow and prevent fire hazards. This involves removing lint buildup, checking for blockages, and ensuring the vent is properly vented to the outside.
Experts recommend cleaning your dryer vent at least once a year, or more frequently if you notice reduced airflow or longer drying times. You can use a dryer vent brush or vacuum attachment to remove lint from the interior of the vent. Additionally, check the exterior vent opening for any obstructions like bird nests or debris that could be restricting airflow.
