Cold vents catch more lint than warm ones
Your dryer pushes out warm, damp air. From October through April, that air is hitting vent walls that sit near freezing on a night averaging 33°F. The moisture in the exhaust condenses fast against the cold metal, and lint sticks to a damp wall much easier than a dry one.
Over a winter, that buildup turns into a real clog. A clogged vent backs up heat and moist air with nowhere to go, and that is a fire risk.

- How often should a dryer vent be cleaned?
- Once a year is the general rule for a household of average size. If you run large loads often, or your duct run is long or has several turns, check it sooner. A vent that takes longer to clean than a straight, short one will trap lint faster.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of duct behind the dryer yourself. A vent brush kit reaches further than your hand and works loose what builds up along the way. But if your duct run is long, goes through the attic, or you can't reach the outside vent hood to check it's clear, a contractor has the tools to clean the whole run and confirm air is moving freely at the exit.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry is the first sign most people notice. Others include the dryer running hotter than usual, a burning smell, the outside vent hood flap barely moving when the dryer runs, and lint collecting around the door or the outside vent itself. Any of these means air isn't escaping the way it should, and it's worth having the duct checked.
