Cold vents catch more lint
Your dryer pushes out warm, wet air every load. Once that air hits the cold metal of the vent, it cools fast, and the moisture in it turns to dampness on the walls of the duct. Lint sticks to a damp surface a lot better than a dry one, so the buildup starts closer to the dryer and spreads from there.
With winter nights averaging 9°F here, the vent run is cold most of the time it's working. A vent that's catching lint low and slow like that can choke down airflow before you'd notice anything wrong, until the dryer starts taking longer to dry a load or the outside hood barely puffs air when it's running.

- How often should a dryer vent be cleaned?
- Once a year for most households, more often if you dry a load nearly every day or you have a long vent run. Lint builds up along the inside of the duct even when the lint trap looks clean, because the trap only catches a portion of what comes off the clothes. A vent that runs slow to clean will show it sooner, since more lint passes through and settles.
- Can I clean my dryer vent myself?
- You can clean the section behind the dryer and the outside hood yourself, but the full run is hard to reach without the right brush and rod setup. Most vents bend at least once between the dryer and the wall or roof cap, and lint collects right at those bends. A shop vac reaches a foot or two in. Anything past that needs a rod long enough to reach the far end and pull lint back out, not just push it deeper.
- 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 burnt smell partway through the cycle are the main ones. Check the outside hood while the dryer runs. If you feel weak airflow or barely any at all, the vent is restricted somewhere along its length. Lint showing up around the drum door or dryer taking noticeably longer than it used to are both worth acting on too.
