Dryer Vent Cleaning: A Hidden Fire Hazard in Your Home

It's easy to overlook, but a clogged dryer vent is one of the most common causes of household fires. The good news: it's also one of the easiest to prevent.

Why lint is dangerous

Lint is highly flammable. As it builds up in the vent line, your dryer runs hotter and works harder — a risky combination.

Warning signs to watch for

• Clothes take more than one cycle to dry
• The laundry room feels hot and humid
• A burning smell when the dryer runs
• The dryer itself is hot to the touch

How often to clean

Once a year is a good baseline for most households — more often if you do a lot of laundry. It protects your home and shortens your drying time.
