For maximum efficiency and safety, be sure to maintain your dryer vents on a yearly basis. Warm/Hot air produced by your dryer is expelled through a duct and then funneled outside of your home through a dryer vent. This vent has an inside and an outside portion, both of which need to be kept free from obstructions. For example, on the exterior portion, lint, leafs,litter and debris can accumulate around a dryer vent over time, as well as nests of birds or rodents. If your dryer vent becomes clogged, it can pose a fire hazard. It can also cause allergens to recirculate into your home, which can be dangerous to you and your family’s health . For peace of mind, inspect your dryer vents often and schedule an annual dryer vent cleaning.
