Cold vents make lint stick
Your dryer pushes out warm, damp air, and that air has to travel through a vent that sits in cold space most of the year. Rockland winter nights average 16°F from December through February, so the vent cools fast. When the warm air hits those cold walls, moisture beads up inside the duct, and lint clings to the wet metal instead of blowing outside.
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 for longer than it should. With heat needed here from September through May, the vent stays cold and damp for most of the year, which gives lint plenty of time to pack in.

- How often should a dryer vent be cleaned?
- Once a year is the standard rule for most households. If you run loads almost daily, or if your vent run is long or has several bends, check it sooner than that. A vent that takes longer to clear lint than it used to is telling you it is due.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of vent yourself, but that only covers part of the job. The rest of the run, especially where it bends or passes through a wall, needs a brush and rod long enough to reach the outside hood. A contractor has the equipment to clear the full length and check that the hood flap is opening and closing the way it should.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry, or come out hot to the touch at the end of a cycle, are the clearest sign. A burning smell while the dryer runs, less airflow at the outside vent hood, or a musty smell in the laundry room are others. Lint building up around the lint trap door or behind the dryer is worth a look too. Any of these on their own is reason enough to have the vent checked.
