Cold vents make lint stick
Your dryer pushes out warm, damp air every time it runs. From October through May, that air is moving through a vent that sits in a cold house or a cold wall, and Brockton winter nights average 23°F. The warm air cools fast inside that cold vent, and the moisture in it makes the lint stick to the walls of the duct instead of blowing straight out.
Once lint builds up along those walls, the vent narrows and the dryer has to push harder to move air through it. A blocked vent also traps heat that the dryer is built to release, and that heat has nowhere to go but back into the duct and the room around it.

- How often should a dryer vent be cleaned?
- Once a year is the general rule. Lint builds up inside the duct even when the lint trap is clean after every load, and that buildup is what blocks airflow. If you dry a lot of loads or the vent run is long, check it partway through the year too.
- Can I clean my dryer vent myself?
- You can clean the first few feet near the dryer yourself. A vacuum and a brush kit will pull lint from the sections you can reach. The rest of the duct, especially where it bends or runs through a wall to the outside vent hood, needs a longer brush or a contractor's equipment to clear properly.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, or come out hot to the touch, are the clearest sign. Check the outside vent hood too. If the flap barely moves or you feel weak airflow when the dryer is running, lint is blocking the path. A burning smell or a dryer that shuts off partway through a cycle means the blockage has gotten serious enough to trip the machine's safety switch.
