Expert Answers: Air Duct, Chimney, and Dryer Vent Cleaning FAQs

Dryer vent cleaning helps prevent fire hazards, improves dryer efficiency, and reduces drying time. Lint buildup in dryer vents is one of the leading causes of residential fires and can also cause your dryer to overheat or wear out faster.

Most homes should have dryer vents cleaned at least once per year. Homes with heavy laundry use, pets, long vent runs, or older dryers may need cleaning every 6–9 months.

Common signs include clothes taking longer to dry, excessive heat in the laundry room, a burning smell, lint accumulating around the dryer, or the dryer shutting off mid-cycle.

Dryer vent cleaning typically takes 30–60 minutes, depending on the length of the vent and the level of buildup. Most cleanings can be completed in a single visit.
