Did you know that dryer vents can cause dangerous house fires? As you can imagine, the dry, fluffy material is highly flammable. The problem is, once there is excessive buildup, it can cause the dryer over heat and ignite the fluff. It can take just a few seconds once ignited to get out of control.
Depending on your dryer usage, thoroughly cleaning your dryer vents should be a regular routine. Clean your filters every time you dry a load, and have your entire dryer vent system cleaned every three years. For your protection, be sure to use reputable technicians who know how to get at every nook and cranny of your dryer vent system from dryer to the outside walls.
