A Controlled Environment Means Better Output: Commercial Ventilation Serving Montréal Call Centers
At AirGreen, we’ve been helping businesses in the service sector optimize their HVAC systems for several years. Call centers in Montréal, Laval, and Longueuil, which operate under high occupancy, extended hours, and continuous activity, are among the most demanding commercial environments in terms of ventilation.
Too often overlooked in favor of air conditioning alone, ventilation actually plays a key role in employee well-being, staff retention, overall productivity—and ultimately, the company’s direct financial performance. In this article, we share a real-world case handled by our team, along with key technical recommendations for any call center manager looking to improve operations.
The Situation: A 80-Desk Floor in Laval with Stuffy Air
Our client, an outsourcing service provider based in Laval, contacted us for a full audit of their HVAC system. For several months, staff turnover had been increasing, with recurring complaints of headaches, afternoon fatigue, and persistent thermal discomfort.
Initial Observations
-
The existing air conditioning system was working, but air quality was poor (CO₂ levels above 1000 ppm)
-
Air renewal was insufficient despite an ERV being in place
-
Air diffusers were poorly positioned, creating cold spots and under-ventilated zones
-
No HVAC maintenance had been performed in over a year
AirGreen Diagnosis: Poor Ventilation Is Hurting Performance
We carried out a detailed technical analysis of airflow, indoor air quality, and the existing equipment. Here are our key findings:
-
The ERV was overloaded for the building’s size
-
Filters were clogged, drastically reducing airflow
-
No smart control system was in place to adjust ventilation based on real-time occupancy
-
Recirculated air was circulating too long without proper fresh air input
Bottom line: the work environment lacked oxygenation, thermal regulation, and consistency—factors directly tied to decreased productivity.
AirGreen’s Intervention: Optimized Ventilation, Boosted Performance
Replacement with a Central LENNOX Ventilation System + High-Efficiency Dual-Flow ERV
We installed a next-gen LENNOX central ventilation system, paired with a high-efficiency dual-flow ERV, offering:
-
A consistent renewal rate adjusted to the number of active workstations
-
Smart airflow management through CO₂ and ambient temperature sensors
-
Reduced thermal loss thanks to high-performance heat exchange
-
Improved air distribution, with strategic repositioning of air diffusers
Structured Maintenance and Remote Monitoring
We also proposed a commercial HVAC maintenance contract that includes:
-
Full biannual service visits
-
Scheduled replacement of high-efficiency filters
-
Remote monitoring of key indoor air quality metrics
-
Quarterly reports sent to management for ongoing performance tracking
Tangible Results After 3 Months
-
Employee satisfaction significantly increased, according to internal surveys
-
Sick leave dropped by 14%
-
Energy consumption decreased by 18%, despite increased ventilation
-
Improved staff retention, with fewer unplanned resignations
Why Ventilation Is a Strategic Lever for Call Center Profitability
The gains from better ventilation are not just theoretical—they’re measurable:
-
Fewer micro-disruptions caused by discomfort
-
Improved average call handling time
-
Reduction in internal complaints
-
Enhanced employer branding
-
Better focus and alertness among teams
Technical Recommendations for Call Center Managers
1. Regularly Audit Your HVAC System
A professional ventilation analysis helps uncover hidden weaknesses that affect performance.
2. Prioritize High-Efficiency, Variable-Speed ERVs
A quality ERV should adapt its power to occupancy levels and minimize thermal losses.
3. Integrate Ventilation into Your Centralized Control System (BMS)
This enables smart management, faster responsiveness, and better operational cost control.
4. Use HEPA or Ultra-High Efficiency Filters
In high-density work environments, air filtration plays a critical role in limiting airborne contaminants.
5. Sign a Structured Commercial Maintenance Contract
Even the best system loses up to 30% efficiency within the first year without regular maintenance.
