Cold air turns dryer lint into a real blockage
Your dryer pushes out warm, damp air every time it runs. In a Boulder winter that vent runs through months of cold, and December through February the nights average 15°F. That warm air cools fast inside a cold vent, and the moisture in it lands on the walls of the duct. Lint sticks to a damp surface far more than it would to a dry one, so the buildup packs in tighter over a long heating season that runs September through June.
A blocked vent keeps that damp air from getting outside. It backs up into the duct and behind the dryer instead, which is where lint fires start.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you dry heavy loads often, towels, bedding, a full house of laundry, a contractor can tell you if your vent needs attention sooner. Lint builds up along the length of the vent, not just in the trap, and that buildup is what slows the dryer down and makes it work harder.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, the trap and the first few feet of duct behind the dryer. A full cleaning means clearing the whole run to where it exits the house, and that often means detaching the vent from the wall or the roof cap, which is harder to do without the right brush and rod set. If your vent run is long or has more than a turn or two, a contractor can get it clean end to end.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that runs hot to the touch, and a burning smell are the clearest signs. Check the outside vent hood too. If little air is moving out of it while the dryer runs, or the flap barely opens, lint is blocking the line. A vent that stays clogged is a fire risk, so these signs are worth acting on rather than working around.
