Cold air turns dryer lint into a wall
Your dryer pushes out warm, damp air every load, and that air has to travel through a vent that runs into a cold attic or along an outside wall. On winter nights that drop to 24°F, that warm air cools fast the moment it hits the vent. The moisture in it turns to dampness on the inside walls of the duct, and lint sticks to it instead of blowing through to the outside.
Over a season that buildup narrows the vent. Your dryer has to push harder to move the same air, runs longer to dry a load, and the motor and heating element work harder to do it.

- How often should a dryer vent be cleaned?
- Once a year is the rule most homes should follow. Lint builds up along the duct every time you dry a load, and it narrows the path air needs to escape through. A house that dries a lot of laundry, or has a long or bent vent run, may need it sooner. If drying takes longer than it used to, that is the vent telling you it is due.
- Can I clean my dryer vent myself?
- You can handle the first few feet, but most of the vent run is out of reach without the right brush and rod set. The duct usually runs through a wall or the attic before it reaches the outside hood, and lint collects at every bend along the way. A shop vac at the dryer end only pulls out what is close to the opening. A contractor brings a rod long enough to clear the full run and check that the outside hood is opening and closing the way it should.
- 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 musty smell in the laundry room are the main ones. Check the outside vent hood while the dryer runs. If the flap barely moves or no air is coming out, the duct is blocked somewhere along its length. A burning smell is not something to wait on. That means lint is sitting near the heating element and the dryer should stay off until the vent is cleared.
