Cold vents make lint stick
Your dryer pushes out warm, damp air every time it runs. Once that air hits the cold vent, it cools fast, and Waterloo winters give it plenty of cold to hit. December through February, nights here average 13°F. The moisture in the exhaust settles on the vent walls, and lint clings to that dampness instead of blowing through to the outside.
Over a winter that buildup narrows the vent. Air moves slower, moisture has longer to collect, and more lint sticks on the way out. A vent that's been cleaned runs clear air straight through. One that hasn't is doing that work with a wall of lint in the way.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run big loads often, or you have a longer duct run to the outside, check it sooner. A vent that is clean at the start of winter is one less thing to worry about once you are running loads through cold, dry air for eight months straight.
- Can I clean my dryer vent myself?
- You can clear the lint trap and the first few feet of duct yourself with a vent brush kit, and that is worth doing between deeper cleanings. What you usually cannot reach is the full run to the outside hood, especially if it bends or travels through an attic or a long wall cavity. A contractor has the rods and the camera to clear the whole line and check that the outside hood is opening and closing the way it should.
- 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 a burning smell are the main ones. Lint building up around the lint trap door or a weak airflow at the outside vent hood are others. Any one of these on its own is worth a look, and if you notice more than one at the same time, get the duct checked before you run another load.
