With winter right around the corner, it’s important to ensure that your furnace and heating systems are running properly before the freezing temperatures set in. A clean duct system, free of debris, will not only keep the air in your home cleaner, but will also help to prevent the possibility of your furnace breaking down in the middle of a cold day. All it takes is one millimetre of dust and dirt to decrease operational efficiency. Clean ducts can also save you money on your heating bills during the winter months.
