Fresno's cold nights turn dryer lint into a clog
Every load of laundry pushes warm, damp air out through the vent. On a night near freezing, that air cools fast against the walls of the duct, and the moisture in it gives the lint somewhere to stick. Instead of blowing out with the exhaust, lint builds up along the vent wall, layer on layer.
Winter nights in Fresno County average 32°F from December through February, so this is not a rare, one-time thing. It happens on the same nights, year after year, all through the eight months homes here run the heat. A vent narrowed by lint takes longer to clear the air out, and the dryer works harder to push it through.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run big loads often, or your vent has a long run to the outside with a lot of turns, it can clog sooner and is worth checking more than once a year. A clean vent lets the dryer push heat and moisture all the way outside instead of trapping it in the line.
- Can I clean my dryer vent myself?
- You can handle the part you can reach, but not the whole line. Pull the lint off the trap after every load and vacuum around the back of the dryer where it connects. The vent itself runs through the wall to an outside hood, often with turns you can't reach or see into, and that's the part that actually clogs. A contractor uses a brush and vacuum system built to clear the full run.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry, a laundry room that feels hot or smells damp after a load, and an outside vent hood flap that barely moves when the dryer runs are the main signs. You might also notice lint around the vent hood outside or a burning smell during the cycle. Any of these means air isn't getting out the way it should, and it's worth having the line checked.
