An invisible yet critical issue for workplace well-being
In the world of commercial heating, energy performance and thermal comfort are often the two primary concerns. However, one equally crucial factor is often overlooked: indoor air quality. At AirGreen, we frequently see that companies in Montréal, Laval, Longueuil, the South Shore, and the North Shore underestimate the direct influence their heating system can have on employee health, productivity, and even absenteeism rates.
Why does indoor air quality suffer because of commercial heating?
A poorly maintained or poorly adapted heating system can become a source of fine particles, dust, mold, and even bacteria. These pollutants then circulate freely in the indoor environment, affecting breathing, concentration, and in more serious cases, causing chronic health issues.
If not regularly inspected, cleaned, and calibrated, commercial HVAC systems can lead to:
-
Increased CO₂ levels in enclosed office spaces
-
Growth of biological contaminants (mold, allergens)
-
Stagnant air circulation that facilitates virus transmission
-
A dry, irritating indoor climate, especially during winter
Case study: A small business in Longueuil and its poorly calibrated heating system
Recently, a 30-employee company based in Longueuil contacted us due to an unusual spike in sick leaves, mainly linked to headaches, nasal irritation, and fatigue. Upon inspection, our team discovered that their central heating system was poorly balanced, lacked proper air purification, and had been neglected in terms of maintenance.
Our interventions:
-
Deep cleaning of ducts
-
Installation of a HEPA filtration system integrated with the central unit
-
Precise adjustment of airflow across different zones
-
Replacement of the central thermostat with an intelligent zoning control system
The result: a 45% reduction in air-quality-related complaints within three months and a measurable improvement in office productivity.
How can your heating system harm your employees' health?
1. Buildup of invisible pollutants
Heating ducts often become long-term reservoirs for dust, mites, spores, fibers, and more. Without regular HVAC maintenance, these elements are recirculated into the work environment.
2. Humidity problems and dry air
Forced-air heating systems, especially in harsh climates like Montréal or Laval, significantly dry out the air. This can lead to respiratory discomfort, skin irritation, and worsened allergies.
3. Inadequate ventilation
A high-performance heating system without proper ventilation becomes a CO₂ trap. The air gets depleted in oxygen, which causes fatigue, loss of concentration, and headaches.
What we recommend at AirGreen
We believe that every company, regardless of size, deserves a healthy indoor environment for its employees. Here are our key recommendations:
Choose integrated ventilation with heating
Many modern systems include automatic air renewal, UV filtration, or ionization-based purification. These technologies guarantee clean, filtered air free of pollutants.
Set up a structured HVAC maintenance plan
We offer custom commercial maintenance packages, including:
-
Complete duct and filter cleaning
-
Equipment calibration
-
Humidity level checks
-
Air quality analysis (CO₂, PM2.5, etc.)
Opt for energy-efficient, certified HVAC systems
Brands like Fujitsu, Gree, Bosch, or Lennox provide central heating systems equipped with air quality sensors, smart controls, and high energy efficiency ratings.

The impact of a good heating system on team performance
Clean indoor air means a more productive, more comfortable environment, and reflects a company that prioritizes the well-being of its people. By ensuring optimal air quality, you:
-
Reduce sick leaves
-
Improve focus and motivation
-
Strengthen your workplace culture
-
Lower energy costs through a high-performance system
Some practical tips
-
Have your systems inspected at least twice a year
-
Watch for signs of poor air quality: odors, visible dust, fatigue
-
Invest in smart thermostats with CO₂ sensors
-
Use HEPA or MERV 13 filters at minimum for your ducts
