Why is it important to clean your dryer vent? Mostly because of energy efficiency but more importantly, if the place one lives in has a dryer, then a lint build up crisis can cause a fire in the home if it has been left long enough. Energy efficiency is key but to live efficiently, a person has to first be alive, so cleaning the vent prevents death; in some cases. The lint trap on the dryer that everybody hopefully cleans when they dry a load is just the beginning.
That plastic tray will clean over half of all the lint being dealt with but some gets by the tray’s defenses, therefore it is important to get the surgery done on the machine, even if the owner isn’t confident as a home appliance engineer. There are places that need dryer vent cleaning and hiring those cleaners contributes to the economy, when the economy isn’t tanking like when it did during the Great Depression. Even if they didn’t have drying machines back during the Great Depression, it would have still been important to clean out the lint from the dryer, had they had the machines; which they did not. What we are dealing with here is one of those stranger moments where a machine needs to be gutted. Lint can become a nuisance if one considers air filtration. I’m sure children out there in the world need clean air to grow and breath.
Lint prevents clean air from staying clean. House fires can be caused by cigarettes being left out, stoves being left on, and a number of other reasons. One of them is not getting duct cleaning done. When a house goes up in a blaze, entire communities of people are put on red alert because houses are big piles of tinder and sometimes the spacing of houses is way too tight, so the fire can hop over to the neighbor and then the neighbor’s neighbor. If one considers how many dryer’s there are out there in the world, then you will understand that the risk in apartment buildings is much higher because the more dryers per building the higher the risk of a fire. One person might be cleaning the duct in his/her apartment but the others may not be doing that, or vice versa. The situation works in reverse too. So be careful and regularly get your ventilation system cleaned up!
