Cold vents catch lint that warm ones let pass
Your dryer pushes out warm, damp air every load. Once that vent runs through cold space, and Kingsport nights average 29°F from December through February, the warm air cools fast before it reaches outside. Lint that would otherwise blow clear sticks to the walls of the vent instead, because damp lint clings and dry lint doesn't.
That buildup narrows the vent a little more each month. Airflow drops, the dryer takes longer to dry a load, and the motor runs hotter than it should. A vent that's mostly blocked traps heat that has nowhere to go.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run big loads often, or dry towels and bedding several times a week, check it more often than that. Lint builds up inside the duct itself, not just in the trap, and that's what a yearly cleaning clears out.
- Can I clean my dryer vent myself?
- You can clean the first few feet near the dryer yourself, but most homes can't reach the whole run. The vent often travels through walls or the attic before it reaches the outside hood, and a vacuum or brush from either end usually won't reach the middle of that path. A contractor uses rods and a brush built to go the full length and pull lint out rather than push it further in.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry, a dryer that runs hot to the touch, and a burnt smell when it's running are the main ones. Weak airflow at the outside vent hood, or the flap barely moving when the dryer is on, points the same way. Lint collecting around the trap slot faster than usual is another sign worth checking.
