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 house for most of the year. Winter nights here average 7°F from December through February, so the metal cools fast, and the moisture in that exhaust condenses on the inside walls of the vent. Lint sticks to a damp surface far more than a dry one.
Once that lint builds up, the vent narrows and the dryer has to push harder to move air through it. A clogged vent means longer dry times, a hotter running dryer, and moist air with nowhere to go but back into the house.

- How often should a dryer vent be cleaned?
- Once a year is the standard for most homes. Lint builds up along the duct walls with every load, and a full year of drying is enough to narrow the airflow even if nothing looks wrong from the lint trap. Homes here run the dryer through 9 months of heating season alongside furnace and other exhaust needs, so a vent that's clear matters for the whole system, not just laundry day.
- Can I clean my dryer vent myself?
- You can clean the first few feet near the dryer yourself, but you can't reach the whole run this way. A vacuum and a brush kit will pull lint out of the section behind the dryer and through the wall opening. The rest of the duct, especially where it bends or runs a long distance to the outside wall, needs a rod-and-brush setup long enough to reach the vent hood. If your dryer takes longer than it used to dry a load, that's usually a sign the blockage is further down the line than you can reach.
- What are the signs of a clogged dryer vent?
- The clearest sign is clothes that take two cycles to dry when one used to be enough. Others include the outside of the dryer feeling hot to the touch, a burning smell during a cycle, and the vent hood flap outside barely moving or not opening at all when the dryer runs. Lint collecting around the lint trap door or finding it in unusual amounts when you clean the trap is also worth paying attention to. Any of these on their own is worth checking, and if the dryer feels hot to the touch, stop using it until the vent is cleared.
