Why does my dryer smell moldy or musty?

Moisture trapped inside the vent system—caused by lint buildup, long duct runs, or duct leaks—creates conditions where mold and mildew can grow.

How do I know if the vent is the problem and not my washer?

Run your dryer empty for 10–20 minutes. If the drum still smells musty, the vent or dryer system is likely the source.

Will cleaning the lint screen fix the smell?

Not usually. Odors often come from deeper in the vent line, where lint and moisture collect beyond the lint trap.

How often should dryer vents be cleaned to prevent smells?

At least once a year, but households with pets, high laundry volume, or long vent runs may need more frequent service.

Will fixing the vent eliminate the odor and improve dryer performance?

Yes. Once airflow is restored and moisture removed, smells disappear, drying times improve, and the system becomes safer and more efficient.
