Cold vents make lint stick
Your dryer pushes out warm, damp air every time it runs. From October through April, that air hits a vent that is sitting in the cold, and on a winter night here that can mean 30 degrees or lower. The moisture in the exhaust cools fast against those cold walls, and the lint riding along with it sticks instead of blowing clear out the hood.
Once lint builds up along the duct, it narrows the path air has to travel. The dryer has to push harder to push exhaust out, and it takes longer to dry a load. Left alone, that buildup is what turns a vent into a fire risk.

- How often should a dryer vent be cleaned?
- Once a year is the general rule for most households. Lint builds up along the whole length of the duct, not just in the trap, and a clogged vent chokes airflow before it becomes obvious. A contractor can tell you if your setup needs more frequent cleaning once they see the duct run.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but you likely cannot clean the whole vent yourself. Pulling the dryer out and vacuuming the first few feet of duct, plus the lint trap and the space around it, helps. The rest of the run to the outside hood usually needs a brush and rod system long enough to reach the full length, since a vacuum from either end will not pull lint through a duct with bends in it.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, or come out hot to the touch instead of just warm, are the clearest sign. Others are a burning smell while it runs, the outside vent hood flap barely moving when the dryer is on, and more lint than usual collecting around the trap. Any of these means air is not moving through the duct the way it should.
