Understanding the Crucial Link Between Commercial Air Conditioning and Humidity Control in Montreal
In the business context of Montreal, where climate fluctuations are extreme, managing indoor humidity is not about comfort—it’s an operational necessity. At AirGreen, we’ve observed through numerous installations across Montreal, Laval, Longueuil, the North Shore and the South Shore that issues stemming from poor indoor humidity control can cause far more than just discomfort: they can jeopardize merchandise integrity, employee productivity, and even result in significant financial losses.
In this article, we’ll explore the invisible risks of excessive or insufficient humidity, the dangers they pose to commercial environments, and most importantly, the real-world HVAC solutions we’ve implemented at AirGreen throughout the Greater Montreal Area.
Why Humidity Is a Silent Enemy for Your Business
The ideal ambient humidity level in an indoor commercial space typically ranges between 30% and 50%. Yet, this range is often overlooked, and the consequences can be serious.
Risks of Excessive Humidity:
-
Mold growth, especially in warehouses or food-related businesses.
-
Corrosion of electronic and mechanical equipment, common in workshops and industrial kitchens.
-
Discomfort for clients and employees, leading to fatigue, headaches, or respiratory issues.
-
Material degradation, like wooden floors, furniture, or moisture-sensitive products (paper, textiles, etc.).
Risks of Insufficient Humidity:
-
Dry respiratory passages, a frequent issue during winter.
-
Excessive static electricity, harmful in tech-based businesses.
-
Cracks in walls or flooring, caused by material shrinkage.
-
Premature drying of products, in food or cosmetic industries.
AirGreen Case Study: Full HVAC Installation in a Clothing Store in Montreal
We were recently called in to intervene at a high-end clothing boutique located on Saint-Denis Street in Montreal. The store owner contacted us after noticing a persistent musty odor, the appearance of mold stains on interior walls, and a rise in returned merchandise due to damage.
After a complete hygrometric analysis, we found the store had a constant humidity level of 72%, well above the norm. We proposed a custom solution by installing a central Daikin air conditioning system with integrated dehumidification, paired with a smart controller that adjusts relative humidity based on schedules and occupancy.
The result:
-
Humidity stabilized at 45% in less than 72 hours.
-
Noticeable reduction of odors.
-
No returned merchandise due to damage in over 3 months.
-
Better comfort for staff (fewer reported headaches).
Technologies We Recommend for Humidity Control
1. Wall-mounted heat pumps with dehumidifier mode
Perfect for small shops or isolated offices, units like the Fujitsu KZAH R-32 or the Gree Lomo+ offer a standalone dehumidification function that works even without active cooling.
2. Central air conditioning systems with hygrometric sensors
Brands like Goodman or Bosch BIVA IDS Premium R-454b feature multi-zone systems that can adjust dehumidification per zone based on specific needs (warehouse, meeting room, reception, etc.).
3. Standalone commercial dehumidifiers
For critical environments like wine cellars, archive rooms, or labs, we offer independent systems, either integrated into the ventilation network or available as mobile solutions.
A Common Mistake: Thinking That Cooling Is Enough
Many business owners believe that a high-performance air conditioning system is enough to control humidity. In reality, dehumidification capacity depends heavily on the embedded technology, proper sizing, and personalized configuration based on real usage of the space.
At AirGreen, we always perform:
-
A thermal and hygrometric assessment beforehand.
-
A modeling of airflow and humidity levels.
-
A precise system sizing that considers occupants, machinery, materials, etc.
More Concrete Examples of Successful Interventions
Restaurant in Longueuil
Installed a variable air volume HVAC system with humidity sensors in each zone: kitchen, storage, and dining area. Result: 38% drop in humidity levels and improved food preservation.
Tech Company in Laval
Integrated a Bosch system with smart control that allows real-time humidity tracking per office, drastically reducing complaints related to static and respiratory discomfort.
Fitness Center in Boisbriand (North Shore)
Added an industrial dehumidifier to the ventilation circuit to offset humidity generated by intense physical activity. Result: drier, healthier air and reduced corrosion on gym equipment.
