Your Ally for Clean and Efficient Commercial Ducts
As cleaning commercial ducts and systems is a complex exercise that must be carried out meticulously, it is necessary to entrust this task to experts. Whether in Montreal, Laval, on the North Shore or the South Shore, Royal Nettoyage is part of this category.
For over 25 years, its teams have been offering cleaning services for commercial building ducts. The company's expertise is well-established: each year, several hundred commercial building managers entrust the maintenance of their building to Royal Nettoyage, a company certified by the National Air Duct Cleaners Association.


A well-maintained and cleaned heating, ventilation and air conditioning system provides many benefits:
- The performance, efficiency and energy efficiency of the appliance are generally better when the HVAC system is cleaned regularly with the right equipment.
- Reducing the amount of dust present in the system allows all of its components to function properly. Concretely, a dust-clogged system can lead to significant heat loss, clog filters, decrease the overall performance of the appliance and cause it to overheat, thus risking significantly reducing its lifespan.
- Building ventilation is improved.
Obviously, air ducts free of dust and contaminants allow all occupants, whether workers or visitors, to benefit from the best possible air quality.

Because all buildings deserve the best
Just like residences, commercial buildings also need to have their ducts cleaned regularly. It goes without saying that these buildings have more complex systems than residential buildings, since they regulate both the heating, relative humidity, air circulation and air conditioning of the building.
Despite their larger size and length, these ducts are not immune to the accumulation of various contaminants over time. On the contrary: depending on the number of occupants in the building and the type of activities carried out in these places, the accumulation of waste and pollutants may be greater. Thus, it is necessary, for the health and safety of all occupants and visitors of the building, to regularly carry out the maintenance of the ventilation, heating and air conditioning (HVAC) system. Indeed, the presence of mold or poor air circulation in a part of the building, for example, can be transported through the ventilation ducts throughout the building and affect the health of its occupants.
It is therefore necessary to entrust experts with the cleaning and regular maintenance of the HVAC system of your commercial building. This is when the Royal Nettoyage team, a force in duct and ventilation system cleaning for over 25 years, comes into play.

A professional and experienced team to take care of your ducts
To carry out each of its commercial duct cleaning interventions, Royal Nettoyage, a well-established company in the field of duct cleaning and sanitation, can count on a team of professional technicians.
What are the effects of regular HVAC system cleaning on the health of building occupants?
In addition to improving the performance of the HVAC system, the primary reason for cleaning the ducts in a commercial building is to ensure the health and safety of the occupants. Dust, mold and bacteria present in the air in too large quantities can be the cause of the appearance of certain ailments.
Well-cleaned ducts then ensure that occupants breathe clean air at all times and are not bothered by contaminants circulating in the building.
How does commercial HVAC system cleaning work?
As commercial buildings are generally large and tall, specialized equipment is required for duct cleaning. Royal Nettoyage uses the most efficient tools - brushes and vacuums - to dislodge accumulations of dust, debris, mites and bacteria in the ducts and remove them from the system inlet.
Each Royal Nettoyage intervention in a commercial building is carried out in such a way that the most frequented spaces, particularly the spaces occupied by offices, common rooms or production areas, are not further contaminated by dust or debris that could settle in these places.
Expert in the field, Royal Nettoyage can count on a team of commercial duct cleaning professionals who are trained to the latest industry standards and norms. Thus, each intervention is carried out meticulously according to the needs expressed by the client.
What other ducts need to be regularly maintained in a commercial or industrial building?
Even if the ventilation, heating and air conditioning system of a commercial building occupies a significant portion of the ducts present in the building, it is nevertheless important to carry out regular cleaning of the other ducts.
Depending on the nature of the activities carried out by the company, other ducts and equipment may also require regular maintenance.
Let's think of dryer ducts, which must, even in a commercial building, be cleaned regularly. Think of bathroom ventilators which can also be found in commercial buildings. Like residential systems, it is also important to have those in commercial buildings cleaned regularly.
Dryer ducts accumulate just as much, if not more, lint over time. To prevent fire hazards and optimize appliance performance, duct cleaning from the exterior exhaust flap is required at least every two years.
If your premises have showers, you need to make sure the rooms are properly ventilated and the humidity is removed after each use. If this is not the case, mold could grow in your building and your ventilation system could contain much more mold than normal and spread it throughout the rest of the building.
Other appliances, such as industrial hoods and appliances for the evacuation and disposal of chemicals, can also influence the nature and frequency of cleaning of your commercial ventilation, heating and air conditioning ducts. Once again, the use of experts, such as the Royal Nettoyage team, is an essential asset for quality and safe work for all occupants of the building.
