Cold vents make lint stick
Your dryer pushes out warm, damp air, and in Troy that air is hitting a vent run sitting in cold space for most of the year. Nights average 17°F from December through February, so the vent cools fast, and the moisture in the exhaust condenses on the inside of the duct. Lint sticks to a damp wall far more than it sticks to a dry one, and that buildup narrows the vent from the inside.
A vent that cannot push air out fast enough backs moisture up into the duct and the room around it. Over a winter that runs eight months, October through May, that buildup only goes one direction unless the vent is cleaned out.

- How often should a dryer vent be cleaned?
- Once a year is the general rule. Lint builds up inside the vent even when the lint trap looks clean, and a full year of drying is enough to pack it tight. If you notice drying times getting longer before the year is up, that is your sign to have it looked at sooner.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but that is usually not the whole vent. Pulling the dryer out and vacuuming the first few feet of duct, plus clearing lint from around the outside vent hood, is worth doing regularly. The rest of the run, especially if it bends through walls or goes up through a roof, needs a brush and rod system built to reach the full length, and that is where a contractor's equipment does more than a shop vac can.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry when one used to be enough is the clearest sign. Others include the outside of the dryer feeling hot to the touch, a burnt smell during the cycle, and little to no airflow when you hold your hand near the outside vent hood while the dryer runs. If the vent hood flap does not open and close with the airflow, or barely moves, that is a clog worth clearing before you run the dryer again.
