If you cleaned them last year, that's fine. But be careful! Don't wait ten years or so for the next cleaning. If you have ventilation and heating ducts, remember to clean them at least once every 3 to 5 years. However, if you've just finished renovating your home, or have just moved into a new house, don't put it off too long. That said, there are other factors to consider when determining the right frequency for your particular situation.

What Criteria Should I Take into Account When Deciding How Often to Clean?

Cleaning frequency varies according to the following factors:


  • Size of the house or flat
  • Number of people living in the household
  • Are there any pets?
  • Whether or not smoking takes place indoors
  • Location (whether you're in the city, countryside, etc.)


In a residence of 1400 square feet occupied by a family of 5, including smoking parents and a dog, for example, you need to think about cleaning more frequently than in a property of the same size inhabited by a non-smoking couple. Schedule an appointment if you notice a decrease in airflow or if you have any symptoms linked to excessive air pollution.

What Different Types of Ducts Need to Be Cleaned?

An air duct cleaning professional will take care of the following :


  • Heating ducts
  • Ventilation ducts
  • Air extractors
  • Dryer exhaust ducts
  • Exterior air vents
  • Filters


This will refurbish your network and leave it spotless from top to bottom.

Why Is It Even More Important to Keep Your Ducts Clean and in Good Condition in Winter?

In Quebec, the cold confines us for at least 7 months of the year. No windows or patio doors open from October to April in la belle province. In other words, the only way to renew the air in the house is through the ventilation system. When summer arrives, Quebecers open their windows and enjoy the pure air without activating any system. As we've just said, winter is a different story: we rely on our ventilation system to clean the air. If you have a faulty network full of dirt and mould, you're not going to enjoy clean indoor air, and we don't want to beat around the bush: it's a health risk. So winter is the time of year to think about the quality of the air we breathe.

Did You Know...?

Several recent studies have shown that indoor air contains more pollutants than outdoor air. This should be taken as a wake-up call: polluted air in the home is a health risk. We can't just sit back and watch! Have you heard of Sick Building Syndrome (SBS)? It occurs where indoor air quality is below the norm. In such conditions, discomforts and disorders such as headaches, dizziness, and nausea are commonplace.


Call in the experts in heating, air conditioning and ventilation system cleaning to avoid this problem. They have specialized equipment that will be much more effective than any sweeper, without damaging your ducts.


Air exchangers and ventilation systems are ducts where dust, mould and other unhealthy substances accumulate. Professionals know how to get rid of them. Heating ducts also concentrate dust and debris in the return ducts. You can do a superficial cleaning with your sweeper, but with a superficial cleaning, the problem will not be eliminated in its entirety. Once again, call in the services of a professional, especially if you haven't even touched your sweeper for years.
