Cold vents make lint stick
Your dryer pushes out warm, damp air, and that air has to travel through a vent that runs through cold space before it reaches outside. With winter nights averaging 20°F from December through February, that vent stays cold most of the day. The warm air cools fast once it hits that metal, and the moisture in it beads up on the walls of the vent. Lint doesn't blow through wet walls. It sticks.
That buildup narrows the path air has to take to get outside. A dryer that can't push air out runs hotter and longer to dry the same load. With heat needed here from September through June, the vent stays in that cold, damp cycle for most of the year.

- How often should a dryer vent be cleaned?
- Once a year is a reasonable baseline for most households. A larger household doing more loads a week will fill the duct with lint faster than a smaller one, so it's worth checking sooner rather than waiting the full year. A straight, short run also collects lint slower than a long one with bends, so the layout of your setup matters too.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but you likely can't clean the whole run. A vacuum and a long brush kit will get lint out of the first few feet behind the dryer and at the outside hood. What builds up further down the duct, especially around a bend, needs a rod system or a vacuum built for the full length, which most homeowners don't have on hand.
- What are the signs of a clogged dryer vent?
- Clothes coming out hot to the touch but still damp is the clearest sign. Others include a laundry room that gets noticeably warmer while the dryer runs, a burning smell, and the outside vent hood flap barely moving when the dryer is on. A cycle that's taking longer than it used to is also worth paying attention to, since a clogged vent is the first thing that slows drying down.
