Cold vents make lint stick
Your dryer pushes out warm, damp air, and that air has a long way to travel through a vent sitting in a cold space. Waukesha County winter nights average 16°F from December through February, so the vent itself runs cold most of the day. Warm air hits those cold walls and cools fast, and the moisture that comes out of it gives the lint somewhere to stick instead of blowing through to the outside.
Once lint holds onto the wall of the vent, more lint catches on it the next time you run a load. The buildup narrows the path a little more each time, and a vent that can't push air out all the way makes the dryer work harder to do the same job.

- How often should a dryer vent be cleaned?
- Once a year, more if you dry a lot of loads or you have a long duct run to the outside. Lint builds up along the way, not just in the trap, and a straight short vent stays clear longer than one with several turns in it. If your dryer runs most days of the week, do not wait the full year to have it checked.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but that is usually not the whole vent. Pulling the dryer out and vacuuming the first few feet of duct helps, and so does clearing the outside hood so it flaps open freely. The lint further down the line, especially past any bends, needs a brush and rod run the full length to actually come out.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry, a dryer that runs hot to the touch, and less air coming out of the outside vent hood than you remember are all signs to watch for. A burning smell during the cycle is another one, and it means stop using the dryer until the vent is checked. Lint collecting around the outside hood or blowing back out when the dryer runs also points to a blockage further down the duct.
