Cold vents catch more lint
Your dryer pushes out warm, damp air, and that air has to travel through a metal duct before it reaches the outside. On a night that averages 24°F, the vent itself is cold, so that warm air cools fast as it moves through. When it cools, the moisture in it starts to stick to the vent walls, and lint clings to those damp spots instead of blowing straight through.
Over a winter that runs from December through February at that kind of cold, this happens on every load. The lint builds up layer by layer along the duct, narrowing the path the air has to take. A vent that is partly blocked forces the dryer to push harder to get the same air out, and the heat that should be leaving the house with the exhaust has nowhere to go but back toward the machine.

- How often should a dryer vent be cleaned?
- Once a year is enough for most households. If you run more loads than most, or you have a longer vent run to the outside, check it partway through the year too. Lint builds up gradually, so a yearly cleaning keeps it from turning into a real blockage.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but it will not get the whole run. Pulling the dryer out and vacuuming the first few feet of duct and the lint trap housing helps, and it is worth doing between full cleanings. The vent hood outside and the length of duct in between usually need a brush and rod system built for the job, especially if the vent run bends or runs longer than a few feet.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry is the clearest sign. Others are a dryer that runs hot to the touch, a burning smell, or the vent hood flap outside barely moving when the dryer is on. If you notice any of these, it is worth having the vent checked before running the dryer again.
