Cold vents make lint stick
Your dryer pushes warm, damp air out through the vent. From December through February, when nights average 21°F, that air hits cold metal and cools fast. The moisture in it beads up on the vent walls, and lint sticks to the wet surface instead of blowing through and out.
Over a winter that runs October through May, that buildup narrows the vent a little at a time. A narrow vent means the dryer takes longer to dry a load, and it means more heat and lint staying inside the vent instead of leaving the house.

- How often should a dryer vent be cleaned?
- Once a year is the standard most contractors work to, though a household running the dryer daily may need it sooner. A clogged vent forces the dryer to run longer to dry each load, and that extra heat has nowhere to go but back into the machine. Checking the vent once a year catches the buildup before it turns into a fire risk or a dryer that won't heat right.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of the vent yourself, but the full length of the duct is harder to reach. Most vents run through walls or up through the roof, and a vacuum alone won't pull lint out of a bend or a long straight run. A contractor uses a brush and rod system built to clear the entire line, not just the part you can see.
- What are the signs of a clogged dryer vent?
- Clothes coming out hot to the touch but still damp is the clearest sign. Others include a burning smell during the cycle, the outside vent hood flap staying shut even when the dryer is running, and lint collecting around the vent opening outside. A load that takes noticeably longer to dry than it used to is the vent telling you it's blocked.
