Cold air in the vent makes lint stick
Your dryer pushes out warm, damp air, and that air has to travel through a vent that runs through a cold house before it reaches outside. From December through February, nights here average 21°F, so a lot of that run sits close to freezing. The warm air cools fast, and when it cools, moisture beads on the inside of the duct. Lint sticks to a wet wall a lot easier than it slides through a dry one.
Over a winter that runs October through May, that buildup narrows the vent from the inside. A dryer working against a narrowing vent takes longer to dry a load and runs hotter doing it.

- How often should a dryer vent be cleaned?
- Once a year is the standard, more often if you dry a lot of loads or the run is long with several bends. Lint builds up along the inside of the duct no matter how clean you keep the trap, and it narrows the path the air has to travel. A vent that empties fast when it's clear will start taking longer with every load as it fills in.
- Can I clean my dryer vent myself?
- You can clean the first few feet near the machine, but most homes have a run that goes through a wall or up through the roof, and that part needs a brush and rod long enough to reach the vent hood outside. A shop vac at one end will only pull out what's close by. If the duct is long or has several turns, a contractor with the right length of rod can clear the whole thing in one pass.
- What are the signs of a clogged dryer vent?
- Clothes coming out hot to the touch but still damp is the clearest sign. You'll also notice the dryer running longer than it used to for the same size load, or the outside of the machine getting warmer than normal. Check the vent hood outside too. If the flap barely moves or you feel little to no airflow when the dryer's running, lint has built up somewhere along the line.
