Why Is Dryer Vent Cleaning Important


Why clean your dryer vents…

Dryer vents become dirty or clogged over time. Lint from clothing, human and animal hair, and whatever we left in our pockets quite often survive the washing machine. As clothes tumble around in the dryer this lint and debris from our clothes become air born. As the air from the dryer escapes through the ventilation system the damp lint and debris follow. Lint being damp as it escapes has a tendency to stick to the outer walls of the ventilation system. The lint over time reduces the air flow which makes the dryer work harder and can even restrict the air from escaping altogether.

If your dryer vents are clogged then the hot air that is supposed to escape isn’t. That means that the damp air is coming into the house. The result can be mould issues. But it can also mean allergy issues too.

Lint-clogged dryer vents create unnecessary wear and tear on dryer parts, which can lead to costly repairs. What kind of repairs? A dryer sucks in air from behind the dryer. The air passes an element very similar to that of an oven. The air blows through the tumbling clothes and then through the ventilation system. If the hot air has nowhere to go or is restricted the dryer begins to heat up. The air in the dryer becomes hotter but doesn’t dry the clothing because no moisture is being released through the vents. The dryer has sensors that will blow once the dryer reaches a certain temperature. The result is expensive repair cost dryer vent.

Also as a dryer is working harder because of inefficiency and lack of air flow, the dryer will consume more energy resulting in higher gas or electric bills.

Clogged dryer vents can also pose as a potential fire hazard. Lint is very flammable. As dryer vents clog, the area surrounding the dryer usually accumulates quite a bit of lint. As the dryer sucks in air to be heated, lint would also be sucked up passing through the heating element. This creates a very dangerous fire hazard.
