Cold air turns dryer lint into a wall of buildup
Your dryer pushes warm, damp air out through the vent every time it runs. Once that air hits the cold part of the run, it cools fast, and the moisture in it turns to condensation on the vent walls. Lint sticks to a wet surface far more than a dry one, so it builds up right there instead of blowing outside.
With winter nights here averaging 6°F from December through February, that vent stays cold most of the day for nine months of the year. The buildup narrows the path the air has to take, and a dryer that cannot push air out has nowhere for the heat and moisture to go but back into your house.

- How often should a dryer vent be cleaned?
- Once a year is the general rule, more often if you dry a lot of loads or your vent run is long. Lint builds up inside the duct even when the lint trap looks clean, because the trap never catches all of it. A vent that runs through more turns or a longer stretch to the outside wall collects lint faster and needs more frequent attention.
- Can I clean my dryer vent myself?
- You can clean the first few feet from the back of the dryer yourself, but the full duct run is harder to reach without the right brush and rod setup. Most home vent kits only get so far before the flexible rod runs out of stiffness or you lose track of where the clog is. If the vent run is long or has several bends, a contractor with the proper equipment can clear it end to end and check that the vent hood outside is opening and closing the way it should.
- What are the signs of a clogged dryer vent?
- Clothes taking longer than one cycle to dry is the biggest sign. Others include the outside of the dryer feeling hot to the touch, a burning smell during the cycle, or very little air coming out of the vent hood when the dryer runs. Lint collecting around the hood outside, or the hood flap not opening on its own, also points to a blockage further down the line.
