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 cold space for most of the year. Morristown winter nights average 30°F from December through February, so the metal walls of the vent stay cold a lot of the time. Warm air hitting that cold metal cools fast, and the moisture in it settles on the walls. Lint sticks to damp metal far more than it does to dry metal, and once a layer builds up, the next load of lint has something to grab onto.
A vent that is closing up this way pushes air out slower, and the dryer has to work harder to push it through. That is more heat and moisture staying inside the vent instead of leaving the house, which only helps more lint stick.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run big loads often or dry a lot of towels and bedding, lint builds up faster and you may want to check it sooner. A vent that's clear lets your dryer push hot air all the way outside instead of trapping it in the duct.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of duct yourself, but most homes can't reach the whole run without taking the vent hood off outside or getting into the wall. A dryer vent brush kit handles the accessible parts. The rest of the duct, especially where it bends or runs a longer distance to the outside wall, needs a contractor with the right tools to clear it fully.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry, a dryer that runs hot to the touch on the outside, and a burning smell are the main ones. Check the vent hood outside too. If the flap barely moves or you don't feel much air when the dryer's running, lint is blocking the path. A weak or missing airflow at that hood is one of the clearest signs something's stuck inside.
