Frequently Asked Questions
Why clean your ventilation ducts regularly?
Your property's ventilation system, including heating and cooling ducts, plays a crucial role in your indoor air quality. All the air circulating inside your home passes through these ducts. Since modern constructions are very airtight and windows aren't always open, maintaining your ventilation or air exchanger system is crucial. As these systems operate daily, regular maintenance of your property's ventilation ducts, including the air exchanger and those designated for heating and cooling, is necessary.
Over time, contaminants like allergens, bacteria, mold, and fungi accumulate in air conditioning and heating units and ducts. Dust and debris also build up. These contaminants can cause discomfort, health problems, and even decrease appliance performance and lead to breakdowns. For all these reasons, your ventilation ducts, regardless of their function, should be cleaned regularly. Royal Nettoyage, an expert in ventilation duct cleaning, recommends cleaning your property's ducts every 3 years according to NADCA standards. This frequency may vary depending on several factors, including:
- Presence of smokers inside the house
- Presence of pets that shed a lot of fur
- Presence of occupants with allergies or asthma, which generally require better air quality
- Recent renovation work
- A reported claim within the building
- Moving into a new property
How can you improve the air quality in your home?
Maintaining a good quality of air in your property requires a lot of care as a homeowner. There are several actions you can take to contribute to good indoor air quality. Cleaning the ducts and appliance components is part of the list of tasks necessary for maintaining good indoor air quality.
Depending on your appliance's specifications and manufacturer's recommendations, replacing filters, cleaning the air exchanger core with water and mild soap, and cleaning the grilles are actions that can be done every season change.
For heating systems, for example, removing dust and debris buildup in the return ducts is recommended. Using a vacuum cleaner with an appropriate brush is ideal for this task.
We recommend hiring a specialized company like Royal Nettoyage to perform a complete duct cleaning. This ensures proper tools and techniques are used, and your ducts are not damaged.
You can make a difference in the air you breathe in your home.
How is a professional cleaning of your property's heating and cooling ducts carried out?
Each year, Royal Nettoyage experts perform hundreds of interventions in Montreal and surrounding cities to clean the ducts of residential heating systems.
This intervention, which should ideally be carried out regularly, requires the use of appropriate tools and techniques to improve, of course, the air quality in the property, but also to improve the overall performance of the appliance.
Thus, the most efficient way to proceed with this operation is to place the system under negative pressure using specialized and powerful vacuum cleaners. Then, brushes specifically designed for this purpose are inserted into the ducts. They dislodge all debris, including allergens, dust, and bacteria, that are stuck on the walls of the ducts before vacuuming them up.
In addition, in the event of microbial contamination present in the ventilation ducts, it is possible to apply a treatment inside the ducts after cleaning. All products used are approved by Environment Canada.
Before and after each intervention in the heating system, Royal Nettoyage experts carry out a visual inspection of the ducts with the customer. The specialized tools and the strict checklist used ensure that the cleaning has been done thoroughly.
The intervention of a team of professionals, such as Royal Nettoyage, ensures your peace of mind and clean ducts.

How to clean your bathroom fan properly?
It may seem trivial, but the duct of the bathroom fan plays a crucial role in maintaining good ambient conditions in your home. More precisely, its role is to evacuate, towards the outside, the excess humidity produced by the condensation that forms during showers and baths.
If the condensation is not properly evacuated, mold could form behind the walls and even spread into the various air ducts of the property. As a result, the indoor air quality as well as the health of the occupants of the household could be compromised.
If, after observing the damper and the fan ducts appear clogged, it is necessary to call in a team of specialists who can clean your ducts. Thus, with their powerful devices, the experts will be able to dislodge all the bacteria, dust, and debris present, thereby ensuring better circulation throughout the rest of the house.
A small gesture that may seem trivial, but which ultimately makes all the difference, cleaning the bathroom fan can significantly improve the air quality in your property.
