Cold air in the vent is what turns lint into a clog

Your dryer pushes out warm, damp air every time it runs. Outside, on a winter night here, the temperature averages 31 degrees. That warm air cools fast once it hits the vent, and the moisture in it has nowhere to go. Lint riding along with the air sticks to those damp walls instead of blowing out the hood.

That buildup narrows the vent a little more each time the dryer runs. Durham homes need heat from October through April, seven months of the year, which means seven months of cold nights working against a vent that is supposed to stay clear.

How often should a dryer vent be cleaned?
Once a year is the usual rule. A contractor can look at your specific setup and tell you if yours needs it more often. Lint builds up along the whole run, not just in the trap, and a straight short vent stays clear longer than one that turns corners.
Can I clean my dryer vent myself?
You can clean the trap and the first few feet yourself. A vacuum with a hose attachment or a vent brush kit will get lint near the wall connection. The part that runs through the wall or ceiling and out to the vent hood is harder to reach, and a contractor has the longer rod systems built to clear it all the way through.
What are the signs of a clogged dryer vent?
Clothes that take longer than one cycle to dry, a dryer that feels hot on the outside, or a burning smell while it runs. Check the vent hood outside too. If the flap barely moves or you feel weak airflow when the dryer is on, lint is blocking the path, and a musty smell in the laundry room can mean moisture is backing up instead of venting outside.
