Cold vents make lint stick faster
Your dryer pushes out warm, damp air, and that air has to travel through a vent that runs through a cold house before it reaches outside. Winter nights here average 1°F, so the metal in that vent gets cold fast. When warm air hits those cold walls, moisture condenses on the inside, and lint clings to it instead of blowing straight through.
Over a winter that runs September through May, that buildup narrows the vent a little more each month. A clogged vent forces your dryer to push harder to move air that has nowhere to go, and the exhaust it can't clear stays trapped in the line behind it.

- How often should a dryer vent be cleaned?
- Once a year for most households. A vent that runs long, or has more than a couple of turns, collects lint faster than a short straight one, so those setups may need a look more often. If the dryer is taking longer to dry a load than it used to, that is a sign to check it sooner rather than wait out the year.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of duct behind the dryer yourself with a vent brush kit. What you can't easily reach is the rest of the run to the outside wall or roof, especially if it's long or has turns, and that's where lint tends to pack tightest. A contractor has the rods to clear 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 longer than one cycle to dry, or come out hot to the touch at the end, are the clearest sign. You may also notice the dryer running hotter than usual, a burning smell, or very little air coming from the vent hood outside when it's running. Lint collecting around the lint trap faster than it used to is another sign the duct behind it is backing up.
