Cold vents give lint somewhere to stick
Your dryer pushes out warm, damp air, and that air has to travel through a vent that sits in a cold attic or against an outside wall. Winter nights here average 22°F from December through February, and homes need heat from October through May. The warm air cools fast once it hits that cold metal, and the moisture in it beads up on the vent walls. Lint sticks to a wet surface far more than a dry one, and it builds up in the bends and at the hood.
Once lint packs into the vent, the dryer has nowhere to push that hot, damp air except back toward the drum, and the lint itself sits there as fuel.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run large loads often, or dry a lot of towels and bedding, lint builds up faster and the vent may need attention more than once a year. Either way, a yearly check keeps lint from packing into the bends and the wall run where you can't see it.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but not the whole run. Pulling the dryer out and vacuuming near the exhaust port and the vent hood outside helps, but the vent has bends and runs through the wall where lint collects out of sight. A contractor uses a brush and rod system built to clear the full length, including the elbows where lint gets stuck first.
- What are the signs of a clogged dryer vent?
- Clothes take more than one cycle to dry, the dryer feels hot to the touch, or the room smells warm and stale while it's running. You may also notice little to no airflow at the vent hood outside when the dryer is on, or lint gathering around the hood itself. Any of these means air isn't moving through the vent the way it should, and it's worth having the line checked before it's blocked completely.
