A neglected ventilation system might seem trivial… until it starts disrupting a business’s daily operations. At AirGreen, we were urgently called to Longueuil to resolve an issue that went far beyond a simple comfort concern. What we uncovered clearly showed how inadequate HVAC ventilation can directly harm employee productivity and a company’s bottom line.
When Air Becomes a Barrier: A Look Back at a Critical Workplace Situation
In Longueuil’s industrial district, a small business specializing in food processing contacted us after several weeks of unexplained drops in productivity. Employees were complaining of recurring headaches, constant fatigue, and a “heavy” feeling in the air. Despite the presence of air conditioning, all signs pointed to a failing ventilation system.
When we visited the facility, our team of experts in commercial ventilation in Longueuil identified a serious issue: the air extraction system hadn’t been serviced in several years. The result? A build-up of dust, nearly non-existent air renewal, and abnormally high humidity levels in certain production areas.
Professional Diagnosis and Rapid Action by AirGreen
At AirGreen, we never settle for surface-level fixes. Here’s how we tackled the situation and helped this business bounce back:
1. Comprehensive Technical Inspection
We conducted a complete ventilation assessment, inspecting every duct, register, and air handling unit. Using specialized equipment, we measured CO2 levels, indoor air quality (IAQ), and static pressure within the ductwork.
2. Deep Cleaning of Ducts and Ventilation Units
We deployed a specialized team to perform a high-pressure mechanical cleaning of the ducts, removing dust, greasy buildup, and mold. We also thoroughly cleaned motors, air filters, and diffuser grilles.
3. Replacement of Faulty Equipment
Several components, especially the extractors located in humid zones, were beyond repair. We replaced them with energy-efficient ENERGY STAR-certified units, properly sized for the required airflow.
4. Rebalancing the Ventilation Network
Through an airflow study, we recalibrated the systems to ensure even air distribution across all departments, including sensitive areas like cold storage rooms and processing stations.
Measurable Results Within the First Week
Just days after our intervention, the company’s management noticed significant changes:
-
Immediate improvement in thermal comfort for employees.
-
Sharp decline in complaints related to fatigue and discomfort.
-
A 12% increase in productivity, based on production line performance.
-
Fewer sick days caused by respiratory issues.
Why Ventilation Is Crucial in Any Enclosed Commercial Space
It’s important to understand that ventilation isn’t just about "moving air around." It plays a vital role in regulating temperature, humidity, and most importantly, air quality. Poor ventilation can lead to:
-
Accumulation of contaminants (CO2, VOCs, dust).
-
Hidden mold growth with harmful health effects.
-
Overworked heating and cooling systems.
For businesses, this translates to:
-
Lower employee performance.
-
Health and safety risks.
-
Higher long-term energy maintenance costs.
