1. Longer Drying Times. Is your dryer working harder than usual to get your clothes dry? If you find yourself running multiple cycles to achieve the same level of dryness, a clogged dryer vent could be the culprit. Lint buildup restricts airflow, making it harder for the dryer to expel moisture efficiently.
2. Your Clothes Smell Musty. When your freshly dried laundry carries an unpleasant, musty odor, it often indicates poor ventilation due to buildup in the vent. The damp environment created by a clogged vent can also foster mold and mildew growth, further exacerbating that weird smell.
3. A Burning Smell When the Dryer is On. A burning smell emanating from your dryer is a serious warning sign that should never be ignored. This could indicate a dangerous lint buildup within the vent, which can ignite and cause a fire hazard. If you notice a burning smell, turn off your dryer immediately and call a professional for dryer vent cleaning.
4. Visible Lint Buildup Around the Vent’s Opening. Check your exterior vent cover. If you notice lint collecting around the opening or the flap not opening fully during operation, it’s time for a thorough cleaning. This visible buildup suggests an even more significant accumulation inside the vent system.
