How to properly maintain all your ventilation ducts?


The main function of a ventilation system is to maintain a comfortable and healthy atmosphere inside a building by replacing stale air with fresh air from the outside. On the other hand, the duct is, as its name indicates, the box through which the air passes to reach its outlet or diffusion point. It is usually rectangular or rounded in shape and requires regular inspection and maintenance.

Pourquoi faut-il procéder régulièrement à l’entretien de ses conduits de ventilation ?

According to recent studies, indoor air is much more polluted than outdoor air. Indeed, it contains a large number of contaminants, bacteria or dirt from household products, decorative elements, mold, animal hair, dust or even breathing.

Despite the presence of filters at the entrance and exit of the ventilation systems, these pollutants eventually reach the ducts and settle on their walls in the long term and will then be redistributed inside, thus affecting the air quality within the building.

However, this is progressively detrimental to the health of the occupants, increasing the risk of all kinds of respiratory diseases. It even threatens the lives of people with allergies or asthma. Therefore, health preservation is the main reason to maintain your ventilation ducts.

In addition, too much dirt and grime inside the housing will impair the proper functioning of the equipment, so it must be cleaned regularly.

When should you service your ventilation ducts?

In general, it is recommended to clean the ventilation ducts at least once every 5 years. However, more frequent maintenance may be required in the following cases:

  • Vous êtes nombreux à occuper le bâtiment, l’appartement ou la maison ;
  • Vous avez des animaux de compagnie ;
  • Un ou plusieurs occupants de la maison sont allergiques ou asthmatiques ;
  • Vous vivez dans une zone où il y a beaucoup de poussière et de pollution.

Also, remember to clean the air ducts after renovations, as dust from the work can get through the filters. Finally, a professional will be able to tell you more precisely how often you should maintain the equipment depending on its type and condition.

How do you properly maintain your air ducts?

To begin with, it is important to note that ventilation system filters should be cleaned monthly, or at least quarterly. Also, be sure to wipe the outlets and inlets daily with a soft cloth (only the accessible parts).

When it comes to cleaning ventilation ducts, we strongly recommend that you call in a professional since this is a difficult and complex operation that requires the use of specific equipment. Also, special care must be taken during the work to preserve the system.
