Mastering Temperature to Save Your Chocolate: The Vital Role of a Well-Designed HVAC System
In the chocolate industry, even the slightest variation in temperature or humidity can ruin weeks of production. Unlike other food sectors, chocolate is a sensitive material—its texture, shine, and shelf life all depend on perfectly stable climatic conditions. In Montréal, Laval, Longueuil, as well as on the North Shore and South Shore, several artisanal and industrial chocolate producers have entrusted their HVAC installations to us to prevent these invisible but costly losses. Here’s a concrete example of a successful AirGreen intervention at a chocolate factory located in Montréal.
Climatic Challenges in a Professional Chocolate Facility
Inside chocolate production spaces, maintaining a stable temperature around 18°C to 20°C with relative humidity between 50% and 60% is essential. Without this, several risks emerge:
-
Fat bloom: white spots on the surface caused by fat crystals due to temperature fluctuations.
-
Sugar bloom: granular deposits caused by condensation after thermal shock.
-
Molding issues: difficult demolding, loss of shine and snap.
-
Flavor deterioration: accelerated oxidation caused by poorly controlled ambient air.
-
Frequent production shutdowns for adjustments or cleaning, causing delivery delays and significant financial losses.
The Chocolate Factory in Montréal: Diagnosis of an Unstable Situation
AirGreen was contacted by a medium-sized chocolate manufacturer located in the Villeray–Saint-Michel–Parc-Extension borough of Montréal. For several months, the company had been facing recurring issues:
-
Fluctuating temperatures in the conching and enrobing rooms.
-
Uneven cooling in storage areas.
-
Poor air distribution causing localized condensation.
-
Product recalls due to surface defects on finished goods.
The technical audit performed by our specialists revealed aging equipment, an unbalanced ductwork network, and the absence of an effective dehumidification system.
The AirGreen Solution: Custom Air Conditioning Installation Featuring Daikin
To meet the high demands of this chocolate facility, we chose to install a Daikin Professional Series Wall-Mounted Inverter air conditioner, 36,000 BTU, capable of precisely controlling temperature and humidity across several independent zones of the site.
Key strengths of this solution:
-
Inverter technology for smooth, precise climate regulation.
-
Advanced air filtration, reducing cross-contamination risks.
-
Hygrometric and thermostatic sensors in every critical zone.
-
Multi-zone programming, to adapt temperature levels to each stage of production.

Results Observed After AirGreen’s Intervention
Within less than a month, the chocolate factory reported:
-
Complete stabilization of temperature, maintained between 18.5°C and 19.5°C in all production zones.
-
Total elimination of condensation on equipment.
-
90% reduction in bloom-related defects.
