Cold air turns lint into a wall inside your vent
Your dryer pushes out warm, damp air, and that air has to travel through a vent that sits in cold space most of the year. Alexandria winter nights average 29°F from December through February, so the air cools fast once it leaves the dryer. Moisture beads up on the inside of the duct, and lint sticks to those wet walls instead of blowing straight outside.
That buildup narrows the vent a little at a time. Air moves slower, more moisture stays trapped inside, and more lint catches on the way out. Left alone, the buildup can block the vent enough that the dryer takes longer to dry a load and runs hotter than it should.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run large loads often, or the vent run is long with a lot of turns, it's worth checking more often than that. Lint builds up inside the duct even when the lint trap looks clean, and that buildup is what slows the dryer down and raises the fire risk.
- Can I clean my dryer vent myself?
- You can clean the section near the dryer and the outside vent hood yourself, but that only covers part of the duct. A vacuum and a brush kit reach a few feet in from each end. The rest of the run, especially where it bends through walls or stretches a long way to an outside wall, needs a rod and brush system built for the full length, which is why a contractor handles the whole duct in one pass.
- 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 are the main ones. You may also notice less airflow at the outside vent hood when the dryer is running, or the hood flap barely moving. Lint collecting around the dryer drum seal or the outside vent opening is another sign worth acting on.
