Cold vents make lint stick
Your dryer pushes out warm, damp air, and that vent runs through cold space to get outside. On winter nights averaging 30°F from December through February, that warm air cools fast against the walls of the vent, and the lint in it stops moving and sticks. Layer by layer, the vent narrows.
A narrowed vent can't get the air out. Drying takes longer, the dryer runs hotter, and the lint that keeps building has nowhere to go but back into the duct or the room around it.

- How often should a dryer vent be cleaned?
- Clean it once a year. Lint builds up along the whole run, not just in the trap, and a longer or bent run collects more of it than a short straight one. If clothes are taking longer to dry than they used to, that is a reason to clean it sooner rather than wait out the year.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but most homeowners cannot clean the whole run. Pulling the dryer out and clearing the first few feet of duct with a vent brush is reasonable work for anyone. The rest of the run is harder, especially where it bends or climbs to reach the outside wall, since lint packed in there needs a longer brush and rod system to push all the way through and out the hood.
- What are the signs of a clogged dryer vent?
- Clothes that take two or more cycles to dry, a dryer that runs hot to the touch, and a burnt smell when it is running are the main signs. Check the outside vent hood too. If the flap barely moves or you feel little to no airflow when the dryer is on, the duct is likely blocked somewhere between the machine and the wall.
