How do I know if my air ducts need to be cleaned? If anyone in your home or office suffers from allergies, breathing or respiratory problems, or if you notice dust inside your home or office, you should consider having your air system cleaned. Why should I get my air ducts cleaned? There are two main reasons you should have your air system cleaned. First, you and your family (or employees) will be breathing cleaner air. Is there anything more important than the health of your loved ones and employees? Secondly, having a clean air system saves money on your energy bill. A clean air system runs more efficiently, and reduces costs for heating and cooling your home.
