Cold vents make the lint stick
Your dryer pushes out warm, damp air, and that air has to travel through vent that sits in a cold space most of the year. On nights that drop to 23°F, the inside of that vent runs cold too. Warm air hits the cold metal and cools fast, and the moisture in it settles on the walls of the duct. Lint sticks to a damp surface far more than a dry one, so it builds up in layers instead of blowing through and out.
That buildup narrows the path the air has to take. A dryer that cannot push air out freely runs hotter and takes longer to dry a load, and a blocked vent is also a fire risk. With heat needed from October through May, the vent stays cold for most of the year, which gives lint plenty of chances to catch and hold.

- How often should a dryer vent be cleaned?
- Clean it at least once a year. If you run big loads often, or your duct run to the outside is long or has several bends, check it sooner than that. Lint builds up along the whole path, not just in the trap, and that buildup is what slows the dryer down and raises the fire risk.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but you likely can't clean the whole vent yourself. Pulling the dryer out and vacuuming near the connection helps, and a vent brush kit can clear a short straight run. Most vents bend through a wall or up through a roof, and lint sitting past those bends needs a longer rod system or a contractor's equipment to reach.
- What are the signs of a clogged dryer vent?
- Clothes take more than one cycle to dry, or come out hot instead of dry. The outside vent hood flap barely moves, or doesn't open at all, when the dryer is running. You may also notice more heat around the dryer than usual, or lint dust near the connection. Any one of these means air isn't moving through the duct the way it should.
