Cold vents catch the lint your dryer pushes out
Your dryer pushes out warm, damp air every time it runs. That air has to travel through a vent that sits in a cold attic or along an outside wall, and here it is cold most of the year. Once that warm air hits the cold metal, it cools fast, and the moisture in it beads up on the inside of the vent.
Lint sticks to a damp wall a lot better than it sticks to a dry one. Over time that buildup narrows the vent, then blocks it. A blocked vent keeps the moist air from getting outside, and that air has to go somewhere. It backs up into the duct, and sometimes into the house.

- How often should a dryer vent be cleaned?
- Once a year is the standard rule. Lint builds up inside the duct even when you clean the lint trap every load, and it narrows the path the air has to take. A dryer working harder to push air out shows up first in longer drying times, before it becomes a fire risk, so a yearly cleaning catches the problem early.
- Can I clean my dryer vent myself?
- You can clean the first few feet near the dryer yourself with a vent brush kit, but you likely can't reach the whole run. Most vents bend through walls or up through a roof, and lint collects at every turn. A contractor has rods and a shop vac built for the full length, plus a way to check that the vent hood outside is actually opening and closing like it should.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, a dryer that runs hot to the touch, and a burning smell are the clearest signs. Check the outside vent hood too. If the flap barely moves or no air comes out when the dryer runs, lint is blocking the path somewhere in the duct. Any of these is worth having a contractor look at, since a blocked vent is a fire hazard, not just an inconvenience.
