Dryer exhaust is another residential venting system where deposits and restrictions matter. Lint can accumulate in ducts, elbows, transition connectors, and exterior terminations. Warning signs include longer drying times, unusually hot loads, repeated cycles, a hot laundry room, or weak airflow outside.
Professional dryer vent cleaning should consider the entire accessible route, not only the wall opening. Long runs, multiple bends, roof exits, damaged ducts, stuck flaps, nests, and crushed flexible transition pieces can affect results.
Clean the lint screen each load and follow dryer and duct manufacturer instructions. Do not run the dryer when you are away or asleep. If burning odor, scorching, smoke, or unusual heat appears, stop the appliance and seek service.
