Step 1 of 3: Equipment
Cold vents catch more lint
Every load sends warm, damp air out through the vent. From October through April, with winter nights averaging 32°F, that vent runs cold most of its length before the air ever gets outside. The warm exhaust cools fast against the cold metal, and the moisture in it beads up on the walls of the vent. Lint sticks to a damp surface far more than a dry one, and it builds up layer by layer where the air cools the most.
A vent that is narrowing with lint takes longer to clear the moist air out of the dryer. That leaves more of it behind to condense on the next load, and the buildup feeds on itself.

- How often should a dryer vent be cleaned?
- Once a year for most households. Lint builds up inside the duct with every load, and a yearly cleaning keeps that buildup from turning into a clog. If the vent run is long, or it bends through an attic or up through the roof instead of straight out a nearby wall, it can fill up faster and may need a look more than once a year.
- Can I clean my dryer vent myself?
- You can clear the parts you can reach, but most homeowners cannot get to the whole vent. A vacuum and a brush from inside the house will pull lint out of the first few feet near the dryer. The rest of the duct, especially where it bends or runs any real distance to the outside wall or roof, needs a longer brush and rod system to reach all the way to the vent hood. A contractor has that equipment and can also check that the vent hood flap opens and closes the way it should.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry is the clearest sign. Others include the outside of the dryer feeling hot to the touch, a burning smell while it runs, less airflow than usual coming from the vent hood outside, and lint building up around the door seal or the hood itself. Any one of these on its own is worth checking.
