Dryer Vent Cleaning · Maintenance

You should have your dryer vent cleaned at least once a year. Clean it more often — every 6 months — if you have a large household, do frequent loads, own pets, or have a long or winding vent run. The biggest reason isn’t just efficiency: a lint-clogged vent is the leading cause of dryer fires. Here’s how to know when yours is due.

Why dryer vent cleaning isn’t optional

Clogged dryer vents are a leading cause of home clothes-dryer fires. The U.S. Fire Administration reports roughly 2,900 dryer fires in homes each year, and the single most common contributing factor is failure to clean them — lint buildup in the vent and lint trap. A once-a-year cleaning for most households is a small step that meaningfully lowers that risk.

Clean more often if you notice

Clothes taking more than one cycle to dry
The dryer or laundry room feeling hot or humid
A burning or musty smell during a cycle
A long or winding vent run, or a large household

Homes with large families, pets, or long vent runs may need service twice a year. Beyond fire safety, a clear vent helps clothes dry faster and reduces wear on the appliance.

Frequently asked questions

What happens if you don’t clean your dryer vent?

Lint buildup restricts airflow, makes the dryer overheat, lengthens drying time, and significantly raises the risk of a dryer fire. The U.S. Fire Administration reports roughly 2,900 home dryer fires a year, most caused by failure to clean.

Can I clean my dryer vent myself?

You can clear the lint trap and the area behind the dryer yourself, but the full vent run – often routed inside walls or to the roofline – needs professional equipment to clean thoroughly and safely.
