How often should exterior vent caps be inspected or replaced?

• A. Annually or whenever you notice damage, obstruction, or reduced airflow.
• B. Monthly.
• C. Every five years.
• D. Only when you hear unusual noise.

Answer: (A)

Exterior vent caps protect the dryer vent from debris, pests, and weather while allowing proper airflow. Over time, lint can accumulate around the cap, birds or small animals can nest nearby, and the cap itself can become damaged or misaligned, all of which can reduce airflow. When airflow is restricted, the dryer runs longer, lint builds up, and the fire risk increases. Because these conditions can develop gradually or be hidden from view, the prudent practice is to inspect the exterior vent cap at least once a year and anytime you notice damage, obstruction, or reduced airflow. If you find damage or a blockage, replace the cap to restore safe, efficient venting. Monthly checks or waiting for unusual noises aren’t typically necessary or sufficient to catch problems early, and waiting five years can miss developing hazards.
