Why does my dryer vent require cleaning?

Dryer vent cleaning involves using specialized tools capable of cleaning narrow pipes and vents. During the process of drying clothes, a dryer blows hot air across fabrics. The machine dislodges very small, lightweight bits of material called “lint” from garments’ surfaces. Most of these fine strands collect within the lint screen (safety experts recommend regularly performing dryer lint screen cleaning for this reason). However, a small percentage of lint passes across the lint screen barrier and exits through a dryer vent. Over time, due to airflow patterns, lint may accumulate within the vent pipe. The delicate strands may form clogs capable of obstructing airflow. Customers help prevent the buildup of lint by performing lint screen cleaning frequently and by asking a cleaner to remove this potentially flammable material at regular intervals.
