Cold vents make lint stick
Your dryer pushes out warm, damp air, and that air has to travel through a vent that sits in a cold attic or against a cold wall most of the year. Jerome winter nights average 22°F from December through February, so the vent itself runs cold most of the time your dryer is on. Warm exhaust hits those cold walls and cools fast, and the moisture in it settles on the metal instead of carrying straight outside. Lint sticks to a damp surface far more easily than a dry one, and it builds up layer by layer along the length of the vent.
A vent that is narrowing with lint gives the dryer less room to push air out. Drying takes longer, the exhaust runs hotter, and the lint packed inside the duct is what a vent fire needs to start.

- How often should a dryer vent be cleaned?
- Once a year is the standard rule, more often if you dry a lot of loads or the duct run is long. A vent that gets away from you restricts airflow and makes every load take longer to dry. If your dryer sits on an exterior wall with a short, straight run to the outside, once a year is usually enough. A longer run with bends in it collects lint faster and is worth checking more often.
- Can I clean my dryer vent myself?
- You can clear the first few feet near the machine and at the exterior hood yourself. A vacuum with a hose attachment or a basic brush kit handles that much. What you can't reach is lint packed further down the duct, especially if the run bends or goes any real distance, and that's the part that actually chokes airflow. A contractor with the right length of brush and a camera can clear the whole run and check that the vent hood flap is opening the way it should.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry, a dryer that runs hot to the touch, and a burnt smell when it's running are the main ones. Lint showing up around the door seal instead of in the trap is another. Check the outside vent hood too. If the flap barely lifts when the dryer is running, air isn't getting through and the duct needs to be cleared.
