The Critical Importance of a Reliable Ventilation System in Schools
At AirGreen, we regularly intervene in educational institutions across Montréal, Laval, Longueuil, the North Shore, and the South Shore to address ventilation issues. Recently, our team was called in for an emergency at a high school in Laval, where an inadequate HVAC system led to a temporary suspension of classes. This real incident clearly demonstrates why an optimal HVAC installation is essential to the smooth operation of schools.
A Real Case: A Crisis Triggered by Failing Ventilation
This Laval high school, with over 800 students, faced a critical situation when several classrooms became unusable due to a failing ventilation system. The initial symptoms were misleading, yet increasingly concerning:
-
Stagnant, suffocating air, leading to repeated complaints from students and teachers.
-
Sudden health issues: headaches, dizziness, and respiratory discomfort.
-
A spike in absenteeism, severely disrupting the regular school schedule.
The school administration, under pressure from concerned parents, had to make the difficult decision to temporarily halt classes in order to ensure the health and safety of students and staff.
Precise Diagnosis by AirGreen’s Expert Team
Upon arrival, we discovered that the issue stemmed from an outdated and poorly maintained ventilation system. Specifically, the school was operating with a system over 20 years old, equipped with obsolete wall-mounted units unable to properly renew the indoor air. Our in-depth inspection revealed several problems:
-
Filters clogged with years of dust buildup, severely restricting airflow.
-
Undersized equipment that was incapable of supporting the actual classroom volume.
-
Alarmingly high CO₂ levels, far above recommended thresholds, creating a potentially hazardous environment.
Technical Solution Implemented by AirGreen in Laval
To effectively resolve these problems and prevent further disruptions to school operations, AirGreen proposed a comprehensive and long-lasting solution:
-
Installation of a high-performance central heat pump, Lennox brand, Elite Series XP25 model, with a capacity of 48,000 BTU, ensuring optimal air renewal throughout the building.
-
Implementation of a controlled mechanical ventilation (HRV) system with heat recovery to guarantee impeccable indoor air quality.
-
Launch of a routine HVAC preventative maintenance plan, including quarterly filter replacements and a full annual system check-up.
Immediate and Long-Term Results Observed by the Institution
Thanks to our swift intervention, the results were quickly noticeable:
-
Immediate restoration of indoor air quality, measured precisely using CO₂ sensors placed at key points in the building.
-
A prompt return to normal operations, with classes resuming just two days after installation work began.
-
A significant improvement in overall comfort reported by both students and teachers, confirmed through positive feedback from the school staff.
Common Mistakes to Avoid in School Environments
Based on our extensive experience working with school HVAC installations throughout Montréal, Laval, Longueuil, and surrounding areas, we’ve identified the following mistakes to avoid at all costs:
-
Underestimating the importance of ventilation in classrooms, where high occupancy requires regular, high-performance air renewal.
-
Neglecting regular maintenance of existing systems, which leads to sudden and costly breakdowns.
-
Installing HVAC systems that are insufficiently sized or poorly adapted to the real dimensions and layout of educational facilities.
Our Recommendations for Optimal School Ventilation
To ensure the sanitary safety and comfort of everyone, AirGreen recommends that schools:
-
Conduct regular detailed audits of existing HVAC installations to detect weaknesses early and address them before serious problems arise.
-
Opt for proven and energy-efficient equipment, such as central or wall-mounted heat pumps, precisely matched to the size of each area.
-
Implement a rigorous preventative maintenance program, including duct cleaning, filter inspections, and in-depth periodic system checks.
Take Advantage of LogisVert Grants from Hydro-Québec in Laval and Surrounding Areas
Another major benefit of choosing high-efficiency solutions is access to grants, such as Hydro-Québec’s LogisVert program. For instance, the installation of an energy-efficient heat pump may qualify for up to $2,500 in financial assistance, making your initial investment much easier to absorb.
