One of the most common dryer vent problems we find isn’t inside the vent system — it’s right behind the dryer.
On a recent service call in the Philadelphia area, we pulled the dryer away from the wall and found lint scattered across the floor and surrounding surfaces. The culprit was a crushed foil connector hose that had been restricting airflow and allowing lint to escape behind the dryer.
When airflow is restricted, lint builds up where it shouldn’t. Drying times increase, the dryer runs hotter, and the risk of a dryer fire increases.
We see this issue regularly in homes with older foil vent hoses. The ridges collect lint, they’re easily crushed when the dryer is pushed back into place, and they don’t perform as well as modern code-compliant vent materials.
If your clothes are taking longer to dry, your dryer feels unusually hot, or you haven’t had your dryer vent inspected in years, it may be time to have the system checked.
This homeowner had no idea there was this much lint accumulating behind the dryer until we moved it.
