Air Carolinas Facts: Why it is so important cleaning your Air Ducts? or your Dryer Vent? Cleaning your ducts regularly not only help you and family breath a better and fresher air but also help you to save money in your energy bill. The pollutants contain dust, pollen, mold spores, animal dander and much more. These materials collect in the furnace, air conditioner and duct surfaces, just as they do on the furniture and floor surfaces. The furniture and floor are cleaned regularly but the duct surfaces are hidden from view and can only be reached by specialized duct cleaning equipment. These pollutants can migrate out into the room again, or become a food source for mold and bacteria, which can thrive in this dark comfortable environment from high humidity or moisture from the air conditioner or humidifiers. Biological growth can release mold spores or toxins into the air system. Also Cleaning your Dryer Vent regularly can protect you and your family against fire hazard.
