From warning signs to AirGreen’s strategic intervention, this is how a simple industrial ventilation maintenance helped a factory in Montréal avoid a complete operational shutdown during peak production season. This story, based on an actual service call received at our Montréal headquarters, clearly illustrates the importance of preventive HVAC maintenance, especially in demanding industrial environments.
An Alert During Production: Early Signs of a Failing Ventilation System
Early in the week, a factory manager located in the Saint-Laurent borough of Montréal contacted us in urgency. Workers were reporting excessive heat and dust accumulation in the production workshop, creating not only discomfort but also a health hazard and a drop in machine performance. This type of situation is critical, as a poorly ventilated environment jeopardizes workplace safety, production quality, and can lead to costly interruptions.
Once on site, our technical team conducted a complete inspection of the ventilation systems. The equipment was a centralized industrial air distribution system installed over eight years ago, with no maintenance done in more than a year—exceeding the recommended standards in the industrial sector.
Technical Diagnosis: Clogged Filters, Dirty Ducts, Overloaded Motors
The inspection quickly revealed several issues:
-
Air filters completely saturated, drastically reducing airflow.
-
Dust buildup inside the ductwork, limiting circulation.
-
Overheated ventilation motors, with abnormal static pressure.
-
Presence of microorganisms in the humid sections of the system (fungal risk).
Without prompt action, the system could have experienced a complete failure, causing a temporary shutdown of the factory and major financial losses.
Strategic Intervention: Complete Maintenance Completed in a Single Day
At AirGreen, we know that every minute counts in an industrial setting. We mobilized two specialized teams, working in parallel to:
-
High-pressure clean the ventilation ducts, with dust capture at the source.
-
Immediately replace the industrial filters, using high-efficiency models (MERV 13).
-
Lubricate and rebalance the motors.
-
Fully disinfect areas at biological risk, using products approved for industrial use.
The entire operation was completed in under 10 hours, ensuring that the night shifts were not disrupted.
Immediate Result: Comfort Restored, Productivity Preserved, Risk Eliminated
By the next day, the client confirmed that ambient temperature was back to normal, air quality had significantly improved, and operators noticed a clear reduction in noise and vibrations in the affected zones.
We also recommended the client set up a quarterly preventive maintenance program, tailored to their production rhythm and the specifics of their industrial HVAC system. This service includes:
-
Regular inspections with detailed reports.
-
Targeted cleaning of critical zones.
-
Scheduled filter replacements.
-
Performance monitoring of motors and fans.
A small investment for a major impact on operational continuity.
What This Service Call Demonstrates: The Importance of Regular HVAC Maintenance in Industrial Settings
This case is far from unique. Many companies in Montréal, Laval, on the North Shore and South Shore, wait until visible signs appear before taking action. Yet, a planned industrial HVAC maintenance offers:
-
Extended lifespan of equipment.
-
Optimized energy consumption.
-
Prevention of unscheduled shutdowns.
-
A safe and compliant work environment.
In Québec’s context—with extreme temperature fluctuations and continuous manufacturing activity—it is essential to rely on local specialists who understand real-world challenges.
