Cold air in the vent makes lint stick
Every load sends warm, damp air out through the vent. On a night that averages 34°F, that air cools fast against the metal walls once it's a few feet in. The moisture in it lets lint stick instead of blowing through to the outside hood.
Once that first layer sticks, more lint catches on it the next load, and the next. A vent that's losing airflow this way runs hotter and takes longer to dry each load, and the buildup doesn't clear itself out.

- How often should a dryer vent be cleaned?
- Once a year keeps most vents clear. A dryer that takes longer to dry a load than it used to, or a laundry room that runs warmer than the rest of the house, means the vent needs clearing sooner than that. Waiting for a full year when you are seeing those signs lets lint keep building where you cannot see it.
- Can I clean my dryer vent myself?
- You can clear the first few feet behind the dryer and the outside hood yourself, with a vacuum hose attachment or a long flexible brush. What you cannot reach is the run in between, especially where it bends or travels any real distance through the house, and that is where lint tends to pack in tight. A contractor has rods and a camera to clear the full length and confirm the vent is actually pushing air outside.
- What are the signs of a clogged dryer vent?
- Clothes that need two cycles to dry, a dryer that runs hot to the touch, and a burning smell are the clearest signs. Lint collecting around the outside vent hood, or a hood flap that barely lifts when the dryer runs, both point to a blockage further down the line. Have the vent cleared before running the dryer again if you notice any of these, since a blocked vent traps heat that has nowhere to go but back into the machine.
