An invisible yet decisive transformation thanks to improved commercial ventilation
In the commercial world, business performance isn’t solely based on the product or service offered. Employee comfort, customer satisfaction, and indoor air quality all play a critical role. At AirGreen, we recently supported a business in Laval through a strategic upgrade of its ERV (Energy Recovery Ventilator). Within just a few months, this technical decision led to a tangible improvement in indoor conditions, better employee performance… and a direct increase in revenue.
The context: a food processing SME
The company, a small-to-medium-sized business with about 25 employees in the agri-food sector, contacted us for a full HVAC system diagnostic. Located in an industrial space in Laval, the company was facing several issues:
-
High humidity levels in the production area
-
Persistent bad odors in the break room and office
-
Thermal discomfort during winter despite active heating
-
Increased absenteeism and reduced team productivity
Our technicians quickly pinpointed the root cause: an outdated fixed-speed ERV, undersized, installed more than 12 years ago and no longer meeting the demands of a growing operation.
AirGreen’s solution: a high-efficiency ERV
Following a detailed analysis, our team recommended installing a Venmar Commercial E15 ECM HRV, a unit perfectly suited for high-occupancy environments. This model, known for its reliability in commercial and industrial settings, offers several key advantages:
-
750 CFM airflow capacity to cover both production and office areas
-
High-efficiency ECM motor delivering significant energy savings
-
Heat recovery core offering up to 85% efficiency, reducing heating loads
-
Smart controls that automatically adjust ventilation cycles based on actual occupancy
The system was also eligible for a LogisVert grant, allowing the business to receive $4,210 back on the total installation cost.
Installation process in Laval: fast, clean, and without operational disruptions
At AirGreen, we understand the constraints of professional environments. That’s why we planned the installation over two days without affecting production:
-
Day 1: removal of the old ERV, ductwork adaptation, electrical setup, and unit installation
-
Day 2: system commissioning, performance testing, and training the maintenance manager on smart settings
Production never had to shut down. Thanks to our coordinated and discreet approach, the project was completed while meeting all safety and sanitary standards.
Results observed after 90 days of use
Improved comfort and employee morale
Within the first week, employees noticed less odor, fresher air, and a clear reduction in end-of-shift fatigue. According to management, positive feedback on the work environment tripled in internal surveys.
Lower humidity and better product preservation
Previously, the food production generated excess moisture, affecting the quality of some finished products. The new HVAC ventilation system stabilized humidity at 42%, improving storage conditions and reducing waste.
Reduced energy consumption
Thanks to the ECM motor and heat recovery system, HVAC-related electricity use dropped by 22%, equivalent to $160 per month—a notable long-term gain.
Direct revenue increase
Finally, according to the owners, the number of orders delivered on time rose by 18%, due to improved operational performance. A three-month sales analysis showed a 6.4% increase in revenue, partially attributed to the improved work environment.
What this case study demonstrates
This real case in Laval highlights a commonly overlooked truth: a properly sized, high-efficiency HVAC system can be a true performance driver for businesses. The initial investment—partially offset by grants and energy savings—quickly pays off through improved productivity and fewer losses.
AirGreen’s recommendations for businesses on the North and South Shores

Have your HVAC ventilation system inspected every 3 to 5 years, especially if your operations are growing
-
Replace old ERVs at the first signs of performance decline or issues (noise, odor, condensation)
-
Take advantage of available financial incentives through provincial programs
-
