What Causes a Clogged Dryer Vent?

Dryer vents clog when enough lint accumulates in the system to cause a blockage.  Dryer vent ducts can clog in a variety of ways.  For example, a long dryer vent run will clog quicker because the lint has too far to go. It clogs toward the end of the run first, where the airflow is slower.  Secondly, when there are turns or curves in the vent, lint will build up there. If the transition hose is crushed from the back of the dryer that connects to the ductwork, you get less airflow, which can also clog your vent.  On the outside of the house is a termination vent. Those can get lint stuck on them which also creates a clogged dryer vent duct.

Safety Concerns

When lint builds up in your dryer vent, it blocks the flow of air from the dryer to the outside exhaust vent. This can cause flammable clothes lint to blow back into the dryer cabinet. Dryer fires can happen if this lint is blown onto the heating element. By having your dryer vent cleared of any lint or debris, you lessen the likelihood of a dryer fire.

Dryer Efficiency

When a dryer cannot exhaust air properly, you have to run the dryer longer to get your clothes dry. That costs you more to run your dryer and it means it takes you longer to finish your laundry. You need to have proper air flow out of your dryer, through the vent duct and through the outside vent cap to get maximum cost reduction and speed of drying. Clogged dryer vent runs also create more backed up heat in the dryer which is bad on parts, as well as hot clothes which can be damaging to them.
