Cold nights turn dryer lint into a wall of buildup

Warm, damp air leaves your dryer and hits the cold walls of the vent. From December through February, when nights average 40°F, that air cools fast, and the lint riding along in it sticks instead of blowing clear outside. Over a winter that runs November through April, the buildup layers on.

A vent that's losing ground doesn't clear itself once spring comes. The lint stays put, packed tighter each time the dryer runs, until air can barely push through to the outside.

How often should a dryer vent be cleaned?
Once a year is the standard for most households. If you dry clothes for a large family or run the dryer almost daily, check it sooner, since lint builds up faster with heavier use. A vent that runs long and straight clears easier than one with several bends, so homes with a longer duct run to the outside wall may need attention more often.
Can I clean my dryer vent myself?
You can clean the lint trap and the first few feet of duct yourself with a vent brush kit. What you can't easily reach is the rest of the run to the outside wall, especially if it bends through framing or travels up through a second story. A contractor has the rods and the vacuum to clear the full length and check that the vent hood outside is opening and closing the way it should.
What are the signs of a clogged dryer vent?
Clothes that take two cycles to dry, a dryer that runs hot to the touch, and a burning smell are the main signs. Check the vent hood outside while the dryer runs. Weak airflow there, or the flap barely moving, means lint is blocking the line somewhere between the dryer and the wall.
