Cold vents turn dryer lint into a wet, sticking mess

Your dryer pushes out warm, damp air every time it runs. From December through February, when nights average 28°F, that air hits a cold vent and cools fast. The moisture in it has nowhere to go but the vent walls, and lint sticks to a damp wall a lot easier than a dry one.

Over a winter that builds into a real clog, not just dust. A blocked vent keeps the moisture from getting out of the house at all, and it keeps your dryer running longer to get clothes dry.

How often should a dryer vent be cleaned?
Once a year is the standard, more often if you run the dryer for a big household or dry a load almost every day. Lint builds up along the length of the vent, not just in the trap, and it narrows the path air needs to escape. A vent that cannot vent properly makes the dryer run longer and work harder to do the same job.
Can I clean my dryer vent myself?
You can clean the parts you can reach, but most of the vent runs behind the wall and out through the roof or siding, and that part takes a brush and rod system built for it. Pulling the dryer out and vacuuming the first few feet of duct and the outside hood helps between full cleanings. A clogged run in the middle of the wall will not show itself until the dryer is already struggling.
What are the signs of a clogged dryer vent?
Clothes that take two cycles to dry, a dryer that feels hot to the touch on the outside, and a burning smell when it runs are the clearest signs. Check the outside vent hood too. If the flap barely moves or no air comes out when the dryer is on, the line is blocked somewhere between the machine and the wall.
