Critical cooling, unexpected failure, and an immediate technical response in the heart of Montreal
During an extreme heatwave in Montreal, air conditioning systems are not just a matter of comfort: for some environments, they are literally vital. This was the case for a medical laboratory located in the Rosemont–La Petite-Patrie borough, where an air conditioner failure could have resulted in the loss of several sensitive biological samples. AirGreen was called in for an emergency, and within less than four hours, we replaced the defective system with a Fujitsu KZAH 18000 BTU heat pump, ensuring stable, precise cooling that met strict health and safety standards.
A Critical Alert in a High-Pressure Medical Environment
It all started on a Friday morning at 7:38 AM when one of the lab technicians discovered that the temperature in the sample collection and analysis room had reached 29.5°C. The previous wall-mounted air conditioner, an older 12000 BTU model, was no longer responding despite several restart attempts. This room had to remain below 22°C at all times, as per the temporary storage guidelines for biological liquids.
An urgent call came in at 8:01 AM. Our emergency team immediately assessed the critical nature of the situation and dispatched two specialized technicians to the location. The diagnosis was made by 8:45 AM: a fried compressor, damaged refrigerant circuit, and no way to repair it on-site in an emergency.
A Custom Replacement with the Fujitsu KZAH 18000 BTU Heat Pump
Faced with this emergency, we immediately recommended a complete replacement. The client approved our suggestion for a Fujitsu KZAH 18000 BTU heat pump, known for:
-
Its exceptional temperature control precision
-
Its 24/7 operational stability, crucial for a laboratory
-
Its high energy efficiency, with a SEER rating of 21
-
Its quiet operation, ideal for professional settings
-
Its use of R-32 refrigerant, which has a low environmental impact
Details of the Intervention: Efficiency, Hygiene, and Compliance
The installation was carried out swiftly. Our technicians removed the old system in less than an hour, all while adhering to strict hygiene and safety protocols required in medical environments: wearing sterile gloves, disinfecting tools, and minimizing movement.
The indoor unit was mounted in the same location but with a reinforced wall bracket to absorb vibrations. The outdoor unit was installed on a vibration-proof base, with a sealed PVC conduit to protect the electrical and refrigerant lines.
The system was up and running by 11:52 AM. By 12:21 PM, the room temperature had already dropped to 21.3°C, meeting the critical temperature standards set by the Ministry of Health.
Testimonial from the Laboratory's Technical Supervisor
“Without AirGreen’s rapid intervention, we would have lost dozens of samples. Their speed, adherence to health regulations, and efficiency are simply remarkable.”
