Spring cleaning and preparation for winter often involves washing floors, organizing closets, and other household chores. Cleaning your ductwork and dryer vents should also be on the “to-do” list. While these two areas are often overlooked, they can greatly impact home and work life. An unclean duct system may contain harmful bacteria, germs, dust mites, mould and mildew. It is imperative to clean ducts after a home renovation or addition. Cleaning can boost furnace and air conditioning efficiency and save you money.
