Step 1 of 3: Equipment
Cold vents trap the lint that warm air carries
Your dryer pushes out warm, damp air every load. From November through April, that air is moving through a vent that sits in cold space, with nights averaging 31°F. The warm air cools fast against the cold walls of the vent, and the moisture in it turns to dampness on the inside. Lint sticks to a damp wall instead of blowing through, and that is where it builds up.
A vent that is closing up with lint gives the air less room to escape. The dryer runs longer to dry the same load, and the exhaust that should leave the house has somewhere to go instead.

- How often should a dryer vent be cleaned?
- Once a year is the usual rule. It matters more here because the dryer runs harder in winter, from November through April, when clothes take longer to dry in cold air. Lint builds up inside the duct even when the lint trap gets cleaned every load, because the trap only catches what passes through it in the dryer itself.
- Can I clean my dryer vent myself?
- You can clean the first few feet from inside the house, but you likely cannot reach the whole run. Most vents travel through a wall or the attic and exit outside through a hood, and a household vacuum or brush will not reach past the first bend or two. A contractor uses a longer brush system built to clear the full length and check the outside hood, which is where lint tends to collect and block the exhaust.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, a dryer that runs hot to the touch on top, and a burning smell during the cycle are the clearest signs. You might also notice less air coming from the outside vent hood when the dryer runs, or lint collecting around the hood flap. Any of these on their own is worth a look, and having more than one at once means the vent needs attention soon.
