Cold nights make the lint stick

Your dryer pushes out warm, damp air every time it runs. On a night in the mid-30s, that air cools fast once it hits the vent. The moisture in it has nowhere to go, so the lint riding along with it sticks to the inside of the duct instead of blowing clear out the hood.

Once lint builds up along those walls, airflow drops. The dryer has to work harder to push air through a narrowing duct, and heat and moisture that should leave the house stay in the line longer. That buildup does not clear itself. It only clears when someone cleans it out.

How often should a dryer vent be cleaned?
Once a year for most households, more often if you dry a load almost every day or have a long duct run to the outside. Lint builds up along the inside of the vent even when the lint trap gets cleaned every time. A vent that's choked with lint makes the dryer run longer and pushes hot, moist air back into the house instead of outside.
Can I clean my dryer vent myself?
You can clean the section right behind the dryer, but the rest of the run is hard to reach without the right brush and rod setup. Most vents bend through walls or ceilings before reaching outside, and lint collects at every turn. A shop vac at the wall opening won't pull lint from the far end of a long duct, so parts of it can stay clogged even after you've cleaned what you can see.
What are the signs of a clogged dryer vent?
Clothes that take longer than one cycle to dry, or that come out hot to the touch but still damp, are the clearest sign. Check the outside vent hood too. If the flap barely opens or you don't feel much air pushing out while the dryer runs, lint is likely blocking the path. A burning smell or a dryer that feels hotter than usual on the outside means the airflow problem needs attention right away.
