An Avoidable Incident That Highlights the Importance of Rigorous HVAC Maintenance
In Laval, a major event at a local manufacturing company perfectly illustrates how HVAC maintenance can have serious consequences on a business’s operations. At AirGreen, we’re regularly called in on emergency cases to resolve critical situations caused by neglected ventilation systems. This specific case clearly shows how a poorly maintained system can lead to a complete shutdown of business activity, impacting not only productivity but also employee health.
A Look Back at a Critical Intervention in a Laval Factory
The call came in on a Monday morning at 7:45 a.m. A company specializing in food processing had to evacuate its premises due to toxic odors and excessive humidity buildup. Upon arrival, our technicians found that the ventilation systems were clogged, the filters completely saturated, and the ductwork covered in mold—undetectable to the eye but unmistakable by smell.
In just 48 hours, our AirGreen team had to:
-
Perform a complete deep cleaning of the entire ventilation network.
-
Replace all damaged industrial air filters.
-
Decontaminate the ducts using Health Canada–approved products.
-
Reprogram the ventilation system to optimize zoned air renewal for production areas.
Once the work was completed, operations resumed safely. The company avoided severe financial losses and a potential report to the CNESST.
The Real Consequences of Neglecting Maintenance
The accumulation of dirt, mold, and microorganisms in a faulty ventilation system poses a major risk. The consequences go beyond just health issues:
-
Unexpected production shutdowns due to inefficient or hazardous ventilation.
-
Increased absenteeism among employees suffering from headaches, allergies, or respiratory problems.
-
Loss of compliance with occupational health and safety standards in industrial settings.
-
Shortened lifespan of HVAC equipment, resulting in repeat expenses.
At AirGreen, we intervene weekly in Laval, Montréal, Longueuil, and throughout the North and South Shores to fix the consequences of neglected systems—often at a much higher cost than a proper preventative maintenance program.
Best Practices to Avoid a Business Shutdown
To ensure your company doesn’t face a similar situation, implement these essential measures today:
-
Schedule regular HVAC maintenance with a certified partner.
-
Clean and inspect air filters quarterly, especially in industrial environments.
-
Conduct an annual indoor air quality audit by a professional.
-
Install CO₂ and fine particle sensors to monitor real-time system performance.
These simple steps ensure a healthy environment while avoiding costly downtime and health authority complaints.

Preventative Maintenance: A Smart Investment
Many businesses wrongly believe that delaying maintenance saves money. In reality, the costs of unexpected breakdowns far exceed those of planned servicing:
-
Premature replacement of major components (fans, motors, specialty filters).
-
Emergency decontamination expenses.
-
Revenue loss from halted activity.
-
Reputational damage for the company.
At AirGreen, we help our clients turn ventilation into a long-term performance asset, not a liability.
