Cold vents catch more lint
Your dryer pushes out warm, damp air, and that air has to travel through a vent that sits inside a cold house for eight months of the year. Winter nights here average 18°F, and against that cold the vent walls stay cool enough that the moisture in the exhaust doesn't just pass through. It settles, and the lint sticks to it.
That buildup narrows the vent a little at a time. Air backs up, the dryer runs hotter and longer to do the same job, and the lint sitting in there is exactly what a vent fire needs.

- How often should a dryer vent be cleaned?
- Once a year is the standard for most homes. Lint builds up inside the vent even when the lint trap looks clean, because the trap only catches part of it. A yearly cleaning clears out what has collected in the duct before it becomes a fire risk or blocks airflow.
- Can I clean my dryer vent myself?
- You can clean the first few feet from inside, where the vent connects to the dryer, with a vacuum or a long brush. The rest of the run is harder to reach, especially past any bends, and a vent that goes up through the roof or out through a long duct is tough to clean without the right tools. A contractor has brushes and rods built for the full length of the vent, including the hood outside where lint tends to catch.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry is the clearest sign. Others include the outside of the dryer feeling hot, a burning smell while it runs, or the vent hood outside barely moving when the dryer is on. Lint around the lint trap door or built up near the outside vent hood is also worth checking, since a clog there restricts airflow all the way back through the duct.
