Cold vents catch more lint
Your dryer pushes out warm, damp air, and from October through May that vent runs through a house working to hold heat against nights averaging 20°F. The metal stays cold, so the moisture in the exhaust condenses on the vent walls instead of blowing straight out. Lint sticks to a damp surface far more than a dry one, and it builds up in layers along the duct.
That buildup narrows the path the air has to escape through. The dryer has to push harder to move the same load of air, and what does get through takes longer to clear the house.

- How often should a dryer vent be cleaned?
- Once a year is the standard, more often if you dry heavy loads like towels or bedding often. Lint builds up along the length of the vent, not just in the trap, and it narrows the path air needs to escape through. A dryer that runs several loads a day pushes more lint through in a year than one used a few times a week, so it may need attention sooner.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of the vent yourself, but the rest of the run is harder to reach. Most vents travel through walls or up through the roof, and a vacuum or brush from the dryer end only reaches so far. A contractor uses rods and brushes built to clean the full length and check the vent hood at the outside end, where lint often packs in tight.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, or that come out hot to the touch instead of just warm, are the clearest sign. You may also notice the outside of the dryer feels warmer than usual, or a burning smell when it runs. Check the vent hood outside the house too. If the flap barely moves or lint is caught on it while the dryer runs, air is not getting out the way it should.
