Cold nights turn lint into a wall inside your vent
Every load of laundry pushes warm, wet air out through the vent. On a winter night in San Marcos, that air hits duct walls sitting near 41°F and the moisture in it condenses fast. Lint that would normally blow through catches on the wet metal instead and stays there.
That buildup narrows the path the air has to travel. The dryer has to push harder to move the same air, and the exhaust that should be leaving the house lingers in the duct longer, cooling and dropping more lint each time.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run big loads often or have a long vent run with a few bends in it, lint builds up faster and you may need it done more than once a year. A clean vent lets your dryer push air all the way outside instead of fighting to get it there.
- Can I clean my dryer vent myself?
- You can clean the section behind the dryer and the outside hood yourself, and that's worth doing between professional cleanings. But most of the lint collects further down the duct, past where a household vacuum or brush can reach, especially if the vent run is long or turns through the wall and roof. A contractor uses rods and a brush sized to the duct to clear the whole run, not just the ends.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry, a dryer that runs hot to the touch, and less airflow than usual at the outside vent hood are the clearest signs. You might also notice a burning smell or more lint than normal collecting around the dryer. Any of these means air isn't moving through the duct the way it should, and that's worth having checked before it gets worse.
