Cold vents make lint stick
Your dryer pushes out warm, damp air, and that air has to travel through a vent that sits in a cold attic or along a cold wall for most of the year. Crystal Lake winters average 17°F at night from December through February, so that vent is cold a good part of the time. The warm air cools fast against those cold walls, and the moisture in it turns to dampness on the inside of the vent. Lint sticks to a damp wall far more than it does to a dry one, and it builds up in layers.
A vent that is narrowing with lint does two things. It makes the dryer work harder to push air out, and it gives any heat from the dryer less room to escape. That is how a clogged vent turns into a fire risk, not just a slow-drying load of laundry.

- How often should a dryer vent be cleaned?
- Once a year is the standard most manufacturers recommend. If you run loads almost every day, or if you have a long duct run to the outside, check it a little more often. A vent that takes longer to clear lint each year usually means airflow is already getting restricted.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet behind the dryer yourself. The rest of the run, especially where it bends or passes through a wall to the outside hood, is harder to reach and easy to damage with the wrong tool. A contractor uses a brush and vacuum sized for the full duct length, including the vent hood outside.
- What are the signs of a clogged dryer vent?
- Clothes taking more than one cycle to dry is the clearest sign. Others include the dryer or the laundry room getting unusually hot, a burning smell, or very little air coming from the outside vent hood when the dryer runs. Lint building up around the vent hood outside is also worth checking, since a hood flap that will not open all the way is often caused by lint packed just inside it.
