Cold vents catch more lint
Your dryer pushes out warm, damp air, and that air has to travel through a vent that runs through cold space before it reaches outside. From December through February, when nights average 27°F, the outer part of that vent stays cold most of the day. The warm air cools fast once it hits that stretch, and the moisture in it settles on the vent walls. Lint sticks to a damp surface much easier than a dry one, and it builds up there instead of blowing outside.
Over a heating season that runs eight months here, that buildup narrows the vent a little more each time you run a load. A tighter vent means the moist air takes longer to clear out, which gives the next load's lint even more to stick to.

- How often should a dryer vent be cleaned?
- Once a year is the standard for most households. A contractor can look at your setup, your vent length and how the dryer gets used, and tell you if yours needs cleaning more often than that.
- Can I clean my dryer vent myself?
- You can clear the first few feet near the machine yourself with a vent brush kit, and that's worth doing. The part you can't reach is the full run to the outside wall, especially if it's long or has bends, and lint further down won't show up until airflow is already restricted. A contractor has the tools to clean the whole length and check the vent hood outside too.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than usual to dry, or come out hot to the touch at the end of a cycle, are the first sign. The dryer itself may feel hot on the outside, or you'll smell something warm and musty rather than clean laundry. Check the vent hood outside too. If the flap barely moves or you feel weak airflow when the dryer's running, lint is building up somewhere in the line.
