Cold vents make lint stick
Sanford winter nights average 16°F from December through February. Your dryer pushes warm, damp air through a vent that runs through cold space, and that air cools fast. When it cools, moisture beads up on the vent walls, and lint sticks to the wet metal instead of blowing outside.
That buildup narrows the vent a little more with each load. Airflow drops, the dryer runs hotter and longer to get clothes dry, and the lint packed inside is exactly what a dryer fire needs to start.

- How often should a dryer vent be cleaned?
- Once a year is the general rule, more if you dry heavy loads often or the vent run is long. Lint builds up along the inside of the pipe even when the lint trap looks clean, and it narrows the path air needs to escape through. A dryer working against a clogged vent takes longer to dry clothes and runs hotter than it should. If you notice drying times creeping up, that's a sign to have it cleaned sooner rather than waiting out the year.
- Can I clean my dryer vent myself?
- You can clean the first few feet from the back of the dryer, but most of the vent run is out of reach without the right tools. A vent brush kit with flexible rods can get further than a vacuum alone, and it's worth doing if your vent run is short and straight. Once the vent has bends in it or runs any real distance to the outside wall, a contractor with a proper cleaning system can clear the whole length and check that the vent hood outside is opening and closing the way it should.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, or that come out hot to the touch but still damp, are the clearest sign. The dryer itself may run hotter than usual, and you might notice a burning smell or lint collecting around the outside vent hood. Check that hood while the dryer is running. If the flap barely moves or you feel little to no air coming out, the vent is blocked somewhere along its length.
