Professional Air Duct Cleaning Explained

You clean your house, your car and your clothes on a regular basis. It’s only natural, nobody likes living in a dirty environment. We all want to breathe clean air indoors, at home or at the office, but how often do you clean your AC system and ducts? In this article our team of certified professionals with over 12 years experience in Montreal and Laval, outline the required equipment and steps for cleaning your air duct system.

Why should I clean my duct?

There are many advantages to cleaning your duct on a regular basis. These include getting rid of harmful mold and vermin that could accumulate in your ducts. A thorough cleaning is also recommended after construction work or renovations given the large amount of dust and debris circulating in the air and settling after these repairs. In addition, cleaning your duct can prevent health problems, enhance air circulation and increase the system’s efficiency and lifespan.

How often should I clean my duct?

Our customers frequently ask us how often they should clean their ducts and the answer is: it depends. Generally, air ducts should be cleaned at least every 3 to 4 years. But there are exceptions. If you suffer from allergies or respiratory illnesses, it is recommended to clean your ducts every 2 years. Similarly, if you live with pets or in a dusty environment (busy street, near constructions or factory sites, fields, etc.), you should clean your ducts every 2 years.

  • Residential (generally): every 3 to 4 years.
  • Commercial/industrial: every 2-3 years.
  • Allergies/having respiratory illnesses: every 2 years.
