When Poor Air Quality Becomes an Invisible Burden at Work
Among the many calls we receive at AirGreen, some tell deeply human stories. That was the case with Mr. Lefebvre, an office employee in Laval who had been suffering from chronic migraines at the end of every workday for years. After consulting multiple specialists, he turned to a commonly overlooked cause: indoor air quality. His employer reached out to us to evaluate and correct the HVAC ventilation system in their commercial office building in Laval.
AirGreen’s Intervention in a Laval Office: Diagnosis, Action, and Results
As soon as we arrived on site, several clues quickly confirmed Mr. Lefebvre’s suspicions. High humidity levels, stale odors, no mechanical air renewal system… everything pointed to an issue of inadequate ventilation, worsened by recent thermal insulation upgrades that made the building more airtight.
Initial Technical Assessment
-
Type of building: 2-story commercial building, built in 1985
-
Number of occupants: about 20 employees
-
Identified issues: fatigue, migraines, thermal discomfort, odors
-
Existing equipment: no air exchanger system, insufficient passive ventilation
Proposed Solution: Installation of a Centralized Ventilation System with Heat Recovery
To ensure constant air quality without thermal losses, we installed a centralized ventilation system with HRV (Heat Recovery Ventilator), connected to a newly implemented automated ventilation control system.
Installation Technical Details
-
Brand and model: VENMAR AVS E15 ECM ERV
-
Airflow capacity: 150 CFM, tailored to air volume requirements per Québec Building Code
-
Ductwork: flexible ducts hidden above the suspended ceiling
-
Control system: programmable timer + CO2 sensors
-
Applicable subsidy: eligible for the LogisVert program (rebate of $700)
-
Installation duration: 3 days with limited access after work hours
Results After 2 Weeks in Operation
Just days after installation, employee feedback was clear: the air felt fresher, the atmosphere lighter, and most importantly, Mr. Lefebvre’s symptoms disappeared. He hasn’t experienced a single migraine since the system was activated.
“It’s like a weight’s been lifted off my shoulders. I get home without a headache—something I haven’t experienced in months.” — Mr. Lefebvre
“The investment is nothing compared to the wellbeing our team has gained. Thank you, AirGreen.” — HR Director
Why Ventilation is Crucial in Workspaces in Laval
The Invisible Impact of Stale Air
Without proper mechanical ventilation, indoor air quickly becomes saturated with pollutants: carbon dioxide, volatile organic compounds, fine particles, excess humidity… This invisible mix directly affects focus, mood, sleep, and overall health.
In Laval, modern buildings are often well sealed, which makes air renewal problems worse. Without mechanical airflow, occupants end up breathing depleted air filled with humidity and contaminants.
Warning Signs You Shouldn’t Ignore
Here are common signs of poor ventilation in the workplace:
-
Persistent fatigue starting early afternoon
-
Recurring headaches
-
Musty or damp odors
-
Feeling of heaviness or heat despite normal room temperature
-
Respiratory issues among certain employees
Tangible Benefits of a Proper HVAC Ventilation System
A well-designed ventilation system not only ensures comfort but also boosts productivity, reduces absenteeism, and safeguards employees’ health. In Mr. Lefebvre’s case, the improvement was immediate, but these benefits also show over the long term: fewer disputes related to discomfort, more energy, and better air for everyone.

Practical Advice for Building Managers in Laval
Get Your Ventilation System Inspected
Never underestimate the importance of having your HVAC system checked regularly. Poorly maintained or improperly calibrated equipment can go unnoticed for years—while significantly impacting your team.
Plan Ventilation According to Occupancy Levels
A system built for 10 people won’t work efficiently for 20. At AirGreen, we size our systems based on actual occupancy and real usage.
Integrate CO2 Sensors into Your Strategy
These low-cost devices allow you to automatically detect stale air and trigger ventilation accordingly. Perfect for meeting rooms, coworking spaces, or enclosed zones without windows.
