Cold vents trap the lint that warm air carries
Your dryer pushes out warm, damp air every time it runs. From December through February, that air is hitting a vent that sits in a cold space, with nighttime temperatures averaging 32°F. The warm air cools fast against those cold walls, and the moisture that comes out of it gives lint something to stick to instead of blowing straight through.
Over a winter that lasts from October through April, 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, and the lint packed against damp walls is what a cleaning clears out.

- How often should a dryer vent be cleaned?
- Once a year is the standard rule for most households. Lint builds up along the length of the duct, not just at the lint trap, so a vent can look fine at the dryer end and still be tight with lint further down. A contractor can check the full run and tell you if yours needs attention sooner.
- Can I clean my dryer vent myself?
- You can handle part of it, but not all of it. Pulling the dryer out and vacuuming the first few feet of duct, plus clearing the exterior vent hood of lint and debris, is reasonable for most homeowners. The trouble is the run in between, especially if the duct is long or has turns, because lint packed deep in the line needs a rod and brush system to clear it out fully, and a shop vac from either end will not reach the middle.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that feels hot to the touch on the outside, and a musty or burning smell during a cycle are the main ones. Weak airflow at the outside vent hood when the dryer is running is another sign, since a clear vent should push air out with some force. If the vent hood flap barely moves or you can feel warm, damp air lingering around the outside vent instead of blowing out, the duct is likely restricted somewhere along its run.
