Cold vents catch more lint
Your dryer pushes out warm, damp air every time it runs. From October through April, that air is hitting a vent that runs through a cold house, and on a winter night here it might only be 33°F on the other side of that duct wall. Warm air cools fast inside a cold vent, and when it cools, the moisture in it settles on the walls of the duct. Lint sticks to a damp surface far more than it sticks to a dry one.
That buildup narrows the path the air has to travel. A dryer working against a partly blocked vent runs hotter and longer to do the same job, and the lint sitting in that duct is exactly what a small spark needs to catch.

- How often should a dryer vent be cleaned?
- A contractor can tell you for sure once they see the length and shape of your vent run, but once a year is the general guideline most manufacturers give. Longer vents and runs with several bends trap more lint and need attention sooner. If clothes are taking longer to dry than they used to, that is a sign it is due now, whatever the calendar says.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but that is usually not the whole job. Pulling the dryer out and vacuuming the first few feet of duct helps, and wiping down the lint trap housing helps too. The rest of the run, especially where it bends or where it exits the house, needs a brush and rod long enough to reach the full length, which is why most homeowners call in a contractor for the complete vent.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry is the biggest one. Others include the outside of the dryer feeling hot to the touch, a burning smell when it runs, little to no airflow at the outside vent hood when the dryer is on, and lint showing up around the dryer door or on the floor behind it. Any of these means air is not moving through the vent the way it should, and that is worth having checked.
