A real case where the performance of an HVAC system literally allowed a company to continue operations despite an extreme heatwave
When we talk about commercial air conditioning, it’s not just about comfort — it’s often about operational survival. In summer, especially during heatwaves experienced in the Laval region, a failure of the HVAC system can jeopardize an entire business. This was the case for a production workshop located in an industrial zone that nearly faced a total shutdown... until AirGreen stepped in.
The context: a record heatwave and an outdated system
The story begins in the middle of July, with temperatures exceeding 35°C for several consecutive days. In the workshop of this Laval SME specializing in metal parts manufacturing, the central air conditioning system was over 15 years old. Poorly maintained, it could no longer cool the premises effectively.
The heat became unbearable. Employees were suffocating, machines were overheating, and production stoppages were increasing. The manager urgently contacted AirGreen, concerned for his team’s safety and the viability of deliveries.
AirGreen’s intervention: quick assessment and tailored solution
The next day, our team went on-site to perform a complete evaluation of the existing HVAC system. Here are the identified issues:
-
Central system undersized for the actual workshop area.
-
Poorly insulated and clogged ducts.
-
A worn-out compressor operating with low energy efficiency.
-
Lack of adequate ventilation in certain production areas.
The solution: a high-performance, properly sized central heat pump
Faced with the urgency and specific client needs, we recommended installing a MIDEA EVOX G3 – 5 Tonnes central heat pump, equipped with Inverter technology and compatible with the eco-friendly refrigerant R-454B.
Technical characteristics of the installed solution:
-
Brand: MIDEA
-
Model: EVOX G3 – 5 Tonnes
-
Type: Central heat pump
-
Capacity: 60,000 BTU
-
Refrigerant: R-454B (low global warming potential)
-
Efficiency: High SEER2, eligible for LogisVert subsidies for North Shore businesses
Installation project details:
Installation was completed in less than 72 hours. We had to:
-
Dismantle the old HVAC system without disrupting production.
-
Install new insulated ducts for better air distribution.
-
Optimize diffusion grids in critical areas.
-
Integrate intelligent zone control, allowing precise energy management.
Results observed from the first week
After commissioning, the impact was immediate:
-
Temperature stabilized at 23°C throughout the workshop, even during the heatwave.
-
Decrease in relative humidity, promoting comfort and operational accuracy.
-
No production interruptions since installation.
-
Notable improvement in employee morale and productivity.
-
Expected reduction of 25% of annual energy costs.
