Cold air turns lint into a real blockage
Every load sends warm, damp air through that vent, and Lakeville winters get down to 10°F on average at night. That air cools fast once it hits the cold metal, and the moisture in it makes the lint stick to the walls of the vent instead of blowing through to the outside. Load after load, the coating gets thicker and the path for air gets narrower.
A blocked vent keeps the moist air from getting outside, and that moisture has to go somewhere. It builds up around the vent hood and inside the duct itself, and a dryer that has to push against a clogged vent runs hotter and longer than it should.

- How often should a dryer vent be cleaned?
- Once a year is the general rule, more often if you run loads daily or your vent run is long. Lint builds up along the inside of the duct even when the lint trap is clean, because the trap only catches what passes through it while air is moving fast. A vent that runs longer than usual or has bends in it collects lint faster than a short, straight one. If you're heating the house from October through May, like most homes around here, a clogged vent also means warm dryer exhaust and moisture staying in the house longer than it should.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but you likely can't clean the whole vent. Pulling the dryer out and vacuuming the first few feet of duct, plus clearing the outside vent hood, is worth doing between full cleanings. The lint further down the run, especially past any bends, needs a brush and rod long enough to reach it, which most people don't have on hand. A contractor with the right length of rod can clear the full run in one pass and check that the vent hood flap is opening and closing the way it should.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry is the clearest sign. Others include the outside of the dryer feeling hot to the touch, a burning smell during a cycle, and the vent hood flap outside barely moving or not moving at all when the dryer runs. Lint building up around the lint trap slot or behind the dryer is also a sign air isn't moving through the vent the way it should. Any of these on their own is worth checking, and more than one at a time means the vent needs attention soon.
