Cold vents make lint stick
Your dryer pushes out warm, damp air, and that air has to travel through a vent that runs through a cold attic or wall before it reaches outside. On a night that averages 14 degrees, the air cools fast once it hits that metal duct. When it cools, the moisture in it settles on the vent walls, and lint sticks to that dampness instead of blowing straight through.
Over a winter that lint builds into a layer, then a clog. A blocked vent keeps the moist air from getting outside, so it backs up into the duct and the dryer runs hotter and longer to push clothes dry.

- How often should a dryer vent be cleaned?
- Once a year is the general rule, and a contractor can tell you if your household needs it more often. Lint builds up inside the vent line even when the lint trap looks clean, and that buildup is what slows the dryer down and strains the heating element. A household that runs the dryer more than most should have the line checked more often than that.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but that is usually just the first few feet. Most vent runs bend behind the dryer, through a wall, and out to a hood on the outside of the house, and lint collects at every bend. A vent cleaning brush kit can get some of it, but a contractor has the length of rod and the vacuum to clear the whole line and check that the vent hood flap outside is opening all the way.
- What are the signs of a clogged dryer vent?
- Clothes take more than one cycle to dry, the top of the dryer feels hot to the touch, or you smell something warm and dusty when it runs. Lint around the outside vent hood or a flap that will not open on its own is another sign. Any of these means air is not moving through the line the way it should, and that is worth checking before the vent gets fully blocked.
