Cold vent walls catch more lint than warm ones

Your dryer pushes out warm, damp air, and in a Bay City winter that air is hitting a vent that runs through cold space for most of its length. Nights average 18°F from December through February, so the vent cools fast. The moisture in the exhaust condenses on those cold walls, and lint sticks to the damp surface instead of blowing outside.

Over a heating season that runs October through May, that buildup narrows the vent a little at a time. A narrower vent means the dryer has to push harder to move the same air, which shows up as longer dry times and a dryer that runs hotter than it should.

How often should a dryer vent be cleaned?
Once a year for most households. If you run a load nearly every day, or the vent run is long with a few turns in it, it's worth checking sooner. Lint builds up along the way, not just in the trap, and a once-a-year cleaning keeps that from becoming a real blockage.
Can I clean my dryer vent myself?
You can clean the first few feet yourself, but not the whole run. Pull the dryer out, disconnect the duct, and clear what you can reach from both ends with a vent brush. Most homes have vent runs that turn corners or travel through a wall to the outside, and lint sitting past that first section needs a longer brush or rod system to reach. If your dryer takes more than one cycle to dry a load, that's usually a sign lint is trapped farther down than a homeowner kit can get to.
What are the signs of a clogged dryer vent?
Clothes coming out hot but still damp is the clearest sign. Others include the outside vent hood flap barely opening when the dryer runs, the dryer or laundry room getting noticeably warmer than usual, and a burning or musty smell during the cycle. Lint building up around the lint trap area faster than normal is another. Any one of these means air isn't moving through the vent the way it should, and it's worth having the full run checked rather than just the trap.
