Cold vents catch more lint than warm ones
Every load pushes warm, damp air out through the vent, and out in a Winona winter that air hits cold metal fast. The moisture in it turns back to water on the vent walls, and lint sticks to wet metal a lot better than it slides through dry metal. Over a winter that runs eight months, that buildup narrows the vent from the inside.
A narrowed vent means the dryer is pushing air against more resistance, so it takes longer to dry a load and runs hotter doing it. Lint sitting damp inside the vent is also just lint sitting where a heat source vents to the outside.

- How often should a dryer vent be cleaned?
- Once a year is the standard most contractors work to. Lint builds up inside the vent line even if you clean the lint trap before every load, because the trap never catches all of it. That buildup narrows the line slowly, so a year is usually enough time for it to matter, and long enough that you would not notice on your own.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach. A vacuum at the dryer end and at the outside vent hood will pull out what sits near the openings. But most of the run is hidden inside the wall, and lint further down needs a brush system built to reach that far. If the run is long or has bends in it, or goes up through the roof, a contractor has the tools to clear the whole line, not just the two ends.
- What are the signs of a clogged dryer vent?
- Clothes that need a second cycle to dry, a dryer that feels hot on the outside, and a burning smell when it runs are the main signs. Check the outside vent hood too. If the flap barely moves or no air comes out while the dryer is running, the line is blocked somewhere between there and the machine. A blocked vent keeps moist heated air from escaping, and that trapped heat is what makes a clogged vent worth dealing with right away.
