Cold air in the vent is what turns lint into a clog
Your dryer pushes out warm, damp air every load. In a Denton winter, with nights averaging 28°F from December through February, that air cools fast once it hits the vent. The moisture in it condenses on the walls of the duct, and lint sticks to those damp walls instead of blowing straight through to the outside.
That buildup narrows the vent a little more with each load. Once it's tight enough, the dryer has to push harder to move the same air, and the exhaust that should be going outside has nowhere to go.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run big loads often, or your vent run is long with a lot of turns, once a year still applies but pay closer attention between cleanings. Lint builds up inside the duct even when the lint trap is clean, and a year is long enough for it to restrict airflow.
- Can I clean my dryer vent myself?
- You can clean the first few feet from the back of the dryer, but that is not the whole vent. Most runs go through a wall or the roof and bend along the way, and lint collects past where a household brush or vacuum can reach. A contractor uses a rod system or a vacuum built for the full length of the duct, including the vent hood outside.
- 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 during the cycle are the main ones. You may also notice less air coming from the outside vent hood when the dryer is running, or lint gathering around the hood itself. Any of these means the duct needs a look, since a blocked vent also puts strain on the dryer's heating element.
