Step 1 of 3: Equipment
Cold vents give lint somewhere to stick
Your dryer pushes out warm, damp air every time it runs. Once that air hits the cold metal of the vent, it cools fast, and lint sticks to the damp walls instead of blowing straight out. On winter nights averaging 34°F from December through February, that cooling happens close to the start of the run, not near the outside hood.
Over a season the lint builds into a lining along the duct. A clogged vent forces the dryer to work against that blockage, and the moisture it can't push outside has nowhere to go but back toward the vent and the wall around it.

- How often should a dryer vent be cleaned?
- Once a year is the standard for most households. If you run large loads often, or if you have noticed clothes taking longer to dry, check it sooner. A vent that stays clear keeps your dryer running the way it should and cuts down on strain that shortens its life.
- Can I clean my dryer vent myself?
- You can clear the section right behind the dryer and at the outside hood yourself, and that is worth doing between full cleanings. But most vents run several feet through walls or ceilings, with bends you cannot reach or see into. A contractor uses a brush and vacuum system built to clear the whole run, including buildup packed into those bends.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, or that come out hot instead of just warm, is the clearest sign. Others include a burning smell while the dryer runs, the outside vent hood barely moving when you check it, and lint showing up around the dryer drum or door seal. Any one of these on its own is worth a look.
