Step 1 of 3: Equipment
Cold cuts the vent's ability to carry lint out
Every load pushes warm, damp air through the vent to the outside. When that vent runs through a cold space, and winter nights here average 15°F from December through February, the air cools fast. Moisture beads on the inside of the duct, and lint sticks to it instead of blowing through.
That buildup narrows the path with every load. Air backs up, the dryer takes longer to finish, and the lint sitting in the vent is what a vent fire needs to start.

- How often should a dryer vent be cleaned?
- Once a year is the standard. Lint builds up inside the vent run even when you clean the lint trap every load, because the trap only catches part of it. A yearly cleaning keeps air moving freely from the dryer to the outside hood, and it lowers the fire risk that comes with a packed vent.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but that is usually not the whole job. Pulling the dryer out and vacuuming the first few feet of duct, plus clearing the outside vent hood, helps. The trouble is the lint that packs into bends and the middle of a long duct run, which needs a brush and rod system fed through the whole line to clear out. A contractor has that equipment and can tell you if the vent run itself is set up in a way that traps lint.
- What are the signs of a clogged dryer vent?
- Clothes taking longer than one cycle to dry is the clearest sign. Others include the outside of the dryer or the laundry room feeling hot while it runs, a burnt smell during the cycle, and little to no airflow when you hold your hand near the outside vent hood while the dryer is on. Lint collecting around the outside hood flap, or the flap not opening at all, points to a blockage further back in the line. Any of these on their own is worth having checked, since a blocked vent makes the dryer work harder than it should.
