Cold vents make lint stick
Your dryer pushes out warm, damp air, and that air has to travel through a vent that sits in cold space for much of the year. Homes here need heat from October through May, and winter nights average 18°F from December through February, so the metal of that vent runs cold for a long stretch. Warm air hits those cold walls and cools fast, and the moisture in it beads up on the metal. Lint sticks to a damp wall far more than it does to a dry one, so it builds up layer by layer instead of blowing straight out.
A vent that is narrowing with lint gives the dryer less room to push air out. Heat and moisture that should leave the house stay in the line longer instead.

- How often should a dryer vent be cleaned?
- Once a year is the general rule. Homes with long vent runs or several bends in the ductwork trap more lint and may need it checked more often. A contractor can look at your setup and tell you if your run needs more frequent attention.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but most of the vent run is hidden in the wall or attic and hard to clear with a vacuum alone. A vent brush kit reaches further than a vacuum hose and works for short, straight runs. Once the vent has bends or runs any real distance, a contractor with the right length of rod and a camera can confirm the whole line is clear, not just the section near the dryer.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that runs hot to the touch, and a burning smell during the cycle are the main signs. You might also notice less airflow coming from the outside vent hood when the dryer is running, or lint collecting around the hood flap. Any of these on their own is worth checking, since a blocked vent makes the dryer work harder and raises the risk of a fire.
