Cold air turns dryer lint into a wall of buildup
Your dryer pushes out warm, damp air every load. In a vent that runs through a cold attic or wall, that air cools fast, and the moisture in it gives the lint somewhere to stick instead of blowing out the hood. Winter nights here average 23°F from December through February, so for eight months a year that vent is working against the cold the whole time.
Lint packed against damp vent walls doesn't clear on its own. It narrows the path a little more with each load until the dryer is pushing air against a wall of its own lint.

- How often should a dryer vent be cleaned?
- Once a year, at minimum. Lint builds up along the inside of the duct no matter how clean you keep the lint trap, and it narrows the path the air has to take to get outside. If your household runs loads almost every day, check it more often than that, since the buildup will happen faster.
- Can I clean my dryer vent myself?
- You can clean the first few feet, but you can't clean the whole run. A vacuum and a brush reach the section right behind the dryer and maybe the wall opening, but most vents run several feet through the wall or ceiling to an outside hood, often with at least one bend. Lint collects at those bends first, and that's the part a homeowner can't get to. A contractor uses a rod and brush system built to travel the full length and clear it out, including the vent hood itself.
- 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 top or sides, and a burning smell when it runs are the main ones. Check the outside vent hood too. If you can't feel air moving out of it while the dryer runs, or the flap barely opens, the duct is blocked somewhere between the dryer and that hood. Lint dust around the dryer or a musty smell in the laundry area are worth checking as well.
