Optimizing comfort while reducing energy costs: a challenge successfully met by AirGreen in Longueuil
In the business world, thermal comfort is not a luxury—it's a strategic necessity. When a Longueuil-based company specializing in food packaging contacted us to replace its outdated air conditioning system, the objective was clear: significantly reduce energy consumption while ensuring optimal cooling of both production and storage areas. Thanks to our expertise, our team designed a custom solution that now allows this business to save over $25,000 annually on energy bills.
An outdated industrial cooling system: a barrier to performance
Before our intervention, the company was relying on a central forced-air system more than 20 years old—inefficient and energy-hungry. The system lacked flexibility, causing significant overconsumption, especially during heatwaves. The client also reported severe temperature fluctuations across different areas of the building, which affected both the quality of stored products and employee comfort.
Our diagnosis revealed several weak points:
-
Major energy losses due to poorly insulated ductwork
-
Oversized compressor, leading to frequent short cycling and inefficient operation
-
Lack of intelligent controls, making any kind of optimization impossible
It was time for this business to upgrade to a modern, efficient HVAC system tailored to industrial needs.
The solution provided by AirGreen: a custom installation of high-efficiency industrial air conditioners
At AirGreen, every installation project starts with a detailed thermal analysis and a feasibility study. For this client, we chose a multi-zone industrial cooling system with high energy efficiency, offering durability, performance, and intelligent control.
Technical details of the installation:
-
Brand installed: Mitsubishi Electric
-
Model: CITY MULTI VRF (Variable Refrigerant Flow) PUMY-P112YKM Series
-
Installed capacity: 38,000 BTU/h per outdoor unit, with 4 indoor units covering distinct zones
-
Refrigerant: R-410A – compliant with current environmental standards
-
Expected energy savings: 40% compared to the old system
-
Grant eligibility: Québec’s ÉcoPerformance program
A complex job, flawlessly executed
The installation took 7 business days, covering the dismantling of the old system, partial rebuilding of the duct distribution system, and the setup of the new VRF units. Several challenges were encountered:
-
The limited rooftop space required a specialized hoisting strategy
-
The work had to be completed without disrupting production
-
The facility layout required precise temperature management to avoid thermal shock to perishable goods
Our technicians rose to the occasion with detailed planning and ongoing coordination with the company’s facility manager.
The results: optimal comfort, substantial savings, and a satisfied client
Three months post-installation, the initial results are more than promising:
-
Average monthly energy bill reduced by $2,100
-
Stable temperatures across all sensitive zones, thanks to room-by-room control
-
Significant noise reduction, improving employee comfort
-
Complete client satisfaction, with plans already in motion to outfit a second location on the South Shore
