Ventilation Ducts: Silent Witnesses of Your Everyday Life
At AirGreen, our expertise in HVAC maintenance throughout Greater Montréal — including Montréal, Laval, Longueuil, the North Shore and the South Shore — has given us a close-up look at a little-known reality: your ventilation ducts tell a story about your lifestyle. During our cleaning services, our technicians find much more than dust — they uncover household habits, potential health risks, and clear signs of neglected or poorly maintained systems.
Here, we share real anecdotes, technical insights, and practical advice drawn from our cleaning services for air ducts, heating systems, ventilation, and air conditioning across Greater Montréal.
Why Your Ventilation Ducts Deserve More Attention
Dirty ducts are more than just a hygiene issue. They often point to a lack of regular maintenance, risky behaviours, or particular living conditions in the home. By neglecting proper cleaning, you're exposing your family to invisible contaminants that continuously circulate in your indoor air.
Typical Case #1: The Smoker's Home
During a cleaning in Chomedey (Laval), our technicians found a greasy yellow-brown film coating the inside of the ducts. The homeowner, a long-time smoker, had no idea that nicotine was sticking to the walls of the ventilation system, affecting both air quality and the overall smell of the house.
What AirGreen Technicians Really Find Inside Your Ducts
Our crews have found:
-
Massive dust buildups from months of accumulation
-
Pet hair clogging up filters
-
Children’s toys stuck in vents
-
Active mold growing in moist ducts
-
Leftover debris from renovations that was never cleaned up
Typical Case #2: Renovated Home, Toxic Air
In Saint-Hubert (South Shore), a client complained about allergy-like symptoms after major home renovations. Upon inspection, we discovered drywall dust, plaster particles, and sawdust had been sucked into the HVAC system. The contractor hadn’t protected the air vents. A thorough duct cleaning resolved the issue almost instantly.
Dirty Ducts: A Sign of a Neglected HVAC System
Dirty ducts don’t just happen. They often reflect:
-
Air filters not replaced regularly
-
Lack of routine maintenance for heating or cooling systems
-
Heavy system usage without cleaning (e.g., pets, renovation zones)
-
Faulty mechanical ventilation, allowing moisture to build up
At AirGreen, we often see these issues in Montréal homes — especially older properties, poorly ventilated spaces, or multi-unit dwellings with shared systems.
Health Risks: What You’re Really Breathing In
The buildup of dust, mold spores, dust mites, pollen, and other allergens in your ductwork dramatically increases the risk of:
-
Asthma attacks
-
Chronic sinus inflammation
-
Heightened seasonal allergies
-
Chronic fatigue from poor air oxygenation
Typical Case #3: A Constantly Sick Child in Repentigny (North Shore)
A family sought medical help for their son’s ongoing health issues, with no answers. We found mold contamination inside their ducts. The ventilation system — never cleaned since they bought the house — was spreading spores throughout the home. After our service, the symptoms greatly improved.
How AirGreen Cleans Your Ducts
Our process follows strict standards:
-
Visual inspection with an HD camera inside the ducts
-
Rotating mechanical brushing to dislodge stubborn grime
-
High-powered vacuum extraction with HEPA filtration
-
Antibacterial/fungicidal treatment if necessary
-
Before/after photo report to prove the results
We respond quickly with professional mobile equipment across Montréal, Laval, Longueuil, the North Shore and the South Shore.
How Often Should You Clean Your Ducts?
We recommend duct cleaning every 3 to 5 years, or more frequently if:
-
You have pets at home
-
You’ve done recent renovations
-
A family member has asthma or allergies
-
You’ve moved into a new property
Mistakes to Avoid
Not changing air filters is one of the most common mistakes. It overloads the ducts. Another misconception: thinking HVAC maintenance is “a luxury.” In truth, it’s an investment in your health, comfort, and the longevity of your equipment.
