Cold vents make lint stick
Every dryer load pushes warm, damp air out through the vent. When that vent runs through a cold space, and Morristown winter nights average 22°F from December through February, the warm air cools fast against the pipe walls. The moisture in it beads up, and lint sticks to the damp metal instead of blowing straight out.
That buildup narrows the vent a little more with each load. Air backs up, the dryer runs hotter and longer to do the same job, and the lint sitting in a warm, damp vent is a fire risk.

- How often should a dryer vent be cleaned?
- A contractor can tell you for certain based on the length of your duct run, but as a rule check it at least once a year. Run several loads a day or have a long vent run with a lot of turns, and lint will build up faster than that. Lint collects inside the duct even when you clean the lint trap every time, because the trap never catches all of it.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but most of the vent run is inside the wall or ceiling and out of sight. A vacuum at the wall opening only pulls lint from the first foot or two. Getting the whole run clean usually takes a brush system built for the length of the duct, or a contractor who has one.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that runs hot to the touch on the outside, and less airflow than usual at the outside vent hood are the main signs. A burning smell during a cycle is also a warning sign and should not wait. Lint collecting around the vent hood outside, or the flap not opening much when the dryer runs, points to a blockage inside the duct.
