Cold vents catch more lint
Your dryer pushes out warm, damp air, and that air has to travel through a vent that sits in a cold house nine months of the year. On a night near 10°F, the metal cools fast. Warm air hits those cold walls and the moisture in it settles out, and lint sticks to a damp surface far more than it does to a dry one.
That buildup narrows the path the air has to take to get outside. A vent that is choked with lint pushes moist, hot air back toward the dryer instead of out of the house, and it makes the dryer work harder to push a load through.

- How often should a dryer vent be cleaned?
- Once a year for most households, more often if you dry a lot of loads or the vent run is long. Lint builds up along the duct walls even when the lint trap gets cleaned every time. A vent that runs longer than it needs to, or a laundry room that feels warmer than usual, is a sign the year mark should move up.
- Can I clean my dryer vent myself?
- You can clean the first few feet from inside the house, but most of the vent run is out of reach without the right brush and rod system. The duct usually travels through a wall or ceiling before it reaches the outside hood, and lint collects the whole way. A contractor can run a brush the full length and check that the vent hood outside is opening and closing the way it should.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that runs hot to the touch, and a burning smell during the cycle are the main signs. Lint showing up around the outside vent hood or the hood flap not opening when the dryer runs is another. Any of these means air isn't moving through the duct the way it should, and it's worth having the vent checked before running more loads.
