The design of your home and the location of your ducts may facilitate the influx of dirt and debris through leaks in the duct walls. If your ducts are located in crawl spaces, for example, you may find that dirt in the area can infiltrate. Additionally, gaseous materials are a serious concern, especially if your leaky ducts are near a combustion appliance, system or device. Leaks can permit dangerous conditions like backdrafting of emissions, posing a serious safety problem to those in your home. If your ducts are near an attached garage, for example, carbon monoxide could infiltrate your home through duct leaks. In addition to cleaning services, the related inspection of your ductwork can be a significant step in ensuring safety for those living in your home. Additionally, it’s important to make the installation of carbon monoxide alarms a priority. Units should be located near attached garages and other areas with the potential for facilitating the movement of carbon monoxide into the home. At least one monitor should be placed on each level of the home, but one monitor per room is preferable as many carbon monoxide deaths occur as affected individuals sleep.
