The venting system of a clothes dryer serves a very important purpose - it exhausts hot, moist air from the dryer outside of your home. Over time, lint and other debris accumulates inside the dryer ductwork. A partial blockage forces the dryer to work harder to push the air out, increasing drying times, wasting energy, and creating potential fire risks.
Industry experts recommend cleaning your dryer vent at least once per year. However, the ideal frequency depends on factors like:
