The answer to 'dryer vent moldy' is that a moldy dryer vent is a common problem that can be caused by several factors, including lint buildup, poor ventilation, and high humidity. Symptoms may include a musty odor, visible mold growth, and reduced airflow from the dryer.
The best solution depends on the severity of the issue. For minor mold, you can often clean the vent yourself using a vent brush, mild detergent, and water. However, for more extensive mold growth or structural damage, it's recommended to call a professional HVAC or mold remediation service to properly inspect and clean the vent to prevent further issues.
