An invisible yet costly issue: how poor ventilation impacts the profitability of workspaces in Montreal
Across Greater Montreal, many businesses occupy office buildings where ventilation is often overlooked, outdated, or poorly maintained. And yet, inefficient ventilation leads to more than just discomfort — it directly affects productivity, employee health, energy costs, and ultimately, the overall profitability of companies. At AirGreen, we regularly work in commercial buildings throughout Montreal, Laval, Longueuil, the North Shore, and the South Shore, where we consistently see the same costly mistakes. This investigation is based on our field observations, real-life projects, and CVAC (HVAC) solutions tailored to the needs of local businesses.
Ventilation in the workplace: an underestimated performance driver
An inadequate ventilation system in an office building can result in:
-
Poor indoor air quality (IAQ), causing headaches, fatigue, irritation, and absenteeism.
-
Loss of concentration due to a buildup of CO₂.
-
Excess humidity, encouraging mold growth, which harms both health and building structure.
-
Higher heating and cooling costs due to poor air circulation and recovery.
On the other hand, a well-designed and well-maintained ventilation system improves productivity, thermal comfort, and a company’s corporate image.
Real case: Ventilation network optimization in Griffintown
Recently, AirGreen was called into an office building in Griffintown, where management faced ongoing employee complaints about headaches and persistent heat. Upon inspection, we found that the ventilation ducts were over 70% clogged with dust and fiber build-up.
Our team:
-
Performed a complete cleaning of the ventilation system (vents, ducts, air exchanger).
-
Installed a smart control system to automatically adjust airflow based on real-time occupancy.
-
Implemented monthly feedback reports with CO₂ sensors to continuously monitor IAQ.
The result: a 30% drop in air quality complaints, a 12% reduction in cooling costs, and a noticeable increase in employee satisfaction.
The hidden costs of neglected maintenance
Many property managers underestimate the impact of poor HVAC maintenance in their buildings. Here are just a few findings from our interventions throughout Greater Montreal:
-
An air exchanger left uncleaned for more than two years can lose up to 40% of its efficiency.
-
Dirty filters increase energy consumption by 15 to 25%.
-
A poorly calibrated ventilation motor can unbalance air pressure, causing acoustic and thermal discomfort.
At AirGreen, we provide a comprehensive HVAC cleaning service, including visual reports, airflow analysis, and a customized maintenance plan tailored to the size and usage of your commercial facilities.
Optimal ventilation: a strategic advantage for businesses
Upgrading your ventilation system isn’t a luxury — it’s a strategic business decision. Proper IAQ contributes to:
-
Talent retention: employees want to work in a healthy environment.
-
Lower absenteeism rates: fewer illnesses related to poor air quality.
-
Compliance with occupational health and safety standards (CNESST and ASHRAE).
-
Increased property appeal: well-ventilated offices rent faster and at higher rates.
