Neglecting to clean your air ducts can turn an efficient central ventilation system into a breeding ground for dust, allergens, and pollutants. At AirGreen, we understand just how much of a difference regular cleaning of your ventilation, air conditioning, or heating ducts can make—not only for your health but for the efficiency of your HVAC system throughout Montreal, Laval, Longueuil, the North Shore, and the South Shore.
It’s All About Clean Air: Why Should You Clean Your Air Ducts?
When thinking about indoor air quality, people often consider solutions like air purifiers or HEPA filters. But even the best technology can’t perform well if the air it processes is moving through filthy ducts.
Over time, air ducts collect layers of dust, pet hair, mold spores, pollen, and sometimes even dead insects or renovation debris. All of this ends up circulating through your living spaces, worsening respiratory issues, triggering allergies, and reducing the quality of your indoor air.
How Often Should You Clean Your Ventilation Ducts?
At AirGreen, we recommend a complete duct cleaning every 3 to 5 years. However, in some cases, a yearly cleaning is recommended—or even essential:
-
Pet owners (fur and dander buildup).
-
Smokers living in the home.
-
People with sensitivities (asthmatics, children, elderly).
-
Recent home renovations (sanding, painting, drywalling).
-
High humidity or history of mold.
-
Oil heating systems or wood-burning stoves.
-
HVAC systems running year-round, especially in multi-story homes.
In commercial, industrial, or high-traffic buildings (daycares, clinics, salons, etc.), twice-yearly cleanings are often necessary.
Client Story: A Home in Laval Overrun by Dust
Recently, a residential client in Laval contacted us because dust kept accumulating despite regular cleaning. After a visual inspection of their ventilation ducts, we found a major buildup of debris caused by renovation work that had never been followed up with a proper duct cleaning. In under four hours, our team performed a full cleaning, including an antibacterial treatment. The result? Noticeably better air quality and a significant drop in allergy symptoms within just a few days.
What Does a Professional Cleaning Look Like with AirGreen?
Our process follows a strict protocol:
-
Initial inspection using cameras to spot problem areas.
-
Site protection: every vent is sealed to prevent dust blowback.
-
Use of an industrial-grade negative air pressure vacuum (HEPA certified).
-
High-speed mechanical brushing of internal duct walls.
-
Full cleaning and disinfection of registers, grilles, coils, and plenums.
-
Optional antifungal and antibacterial treatment upon request.
We guarantee a dust-free operation that delivers immediate improvements in comfort and HVAC system efficiency.
Signs Your Ducts Are Due for a Cleaning
Here are common signs that your air ducts need professional cleaning:
-
Dust returns quickly after cleaning the home.
-
Persistent odors (mustiness, smoke, humidity…).
-
Ongoing allergy or irritation symptoms.
-
Unusual noises coming from the ducts.
-
Visible mold or signs of insects.
-
Uneven temperatures from one room to another.
If you’re noticing one or more of these issues, it’s time to schedule an inspection.
