Cold vents make lint stick
Your dryer pushes warm, damp air out through the vent. Once that vent runs through cold space, the air inside it cools fast. On a night near 16°F the metal of the vent is just as cold, and the moisture in the exhaust settles on the walls of the duct instead of blowing clear out the hood. Lint sticks to a damp surface far more than a dry one, so the buildup collects right there instead of leaving the house.
That blockage does not stay a lint problem. A vent that cannot push air out backs up into the dryer itself, and the moist air has to go somewhere. Over a winter that runs eight months here, a vent that stays wet inside and clogged with lint is also a vent that cannot do its job of getting that exhaust out of the house.

- How often should a dryer vent be cleaned?
- Once a year is the general rule. If you run the dryer several times a week or the duct run to the outside wall is long, check it sooner. Lint builds up along the whole length of the vent, not just at the lint trap, so a yearly cleaning keeps air moving the way it should.
- Can I clean my dryer vent myself?
- You can clean the first few feet, but you likely cannot reach the whole run. A vacuum and a brush from the inside will get lint near the dryer and near the vent hood outside. The middle of the duct, especially where it bends or runs through a wall, needs a longer rod or a professional's equipment to clear.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that feels hot to the touch on the outside, and a burning smell when it runs are the main signs. Check the vent hood outside too. If the flap barely moves or you feel weak airflow when the dryer is on, lint is blocking the path somewhere along the duct.
