Cold vents catch more lint
Your dryer pushes out warm, damp air every load. Once that air hits the cold vent run, it cools fast, and lint sticks to the damp walls instead of blowing outside. From December through February, nights here average 30°F, so the vent stays cold most of the time it's working.
That buildup narrows the vent a little more with each load. The dryer has to push harder to move air through it, and heat has nowhere to go but back into the vent walls and the room around it.

- How often should a dryer vent be cleaned?
- Once a year, at minimum. Lint builds up along the whole length of the vent, not just in the trap, and a year is about how long it takes to narrow the airflow enough to matter. If you run the dryer for a large household or dry loads almost daily, check it sooner rather than waiting for the yearly mark.
- Can I clean my dryer vent myself?
- You can clean the first few feet, but you likely can't reach the whole run. A vacuum with a hose attachment or a basic brush kit will pull lint out near the dryer and near the outside vent hood. What you can't see is the middle of the duct, especially where it turns corners or runs any real distance, and that's often where lint collects most. A contractor uses a brush and rod system long enough to clear the full length and confirm the vent hood flap opens and closes freely.
- What are the signs of a clogged dryer vent?
- Clothes taking longer than one cycle to dry is the biggest sign. Others include the outside of the dryer feeling hot to the touch, a burnt smell during the cycle, little to no airflow at the outside vent hood when the dryer runs, and lint showing up around the dryer door seal. If you notice more than one of these, it's worth having the vent checked before running the dryer again.
