When fast HVAC intervention becomes a public health matter
In the middle of July, as temperatures in Laval soared past 33°C, a local pharmacy experienced a total failure of its central air conditioning system. Far from being a simple comfort issue, this was a medical emergency: some medications must be kept at a stable temperature, staff were working under extreme conditions, and vulnerable clients (seniors, children, patients in treatment) were exposed to intense heat.
At AirGreen, we responded immediately, mobilizing a dedicated team in under 4 hours to restore a safe, functional environment that met pharmaceutical standards. Here’s the full account of this critical commercial HVAC intervention in Laval.
Red flags: complete AC breakdown and critical in-store temperature
Early that morning, the head pharmacist noticed:
-
The air was stifling as soon as the doors opened;
-
The central system wouldn’t turn on — no noise, no airflow;
-
The pharmaceutical fridges were starting to overcompensate.
Emergency call received at AirGreen at 8:12 a.m.: one of our HVAC project leads specializing in commercial systems took the call immediately.
Fast technical diagnosis and root cause identification
Our technical team arrived on-site at 11:40 a.m. in Laval, equipped with all tools and commonly needed replacement parts. After a full inspection, we identified:
-
An electrical failure on the central air conditioner’s control board;
-
A faulty outdoor fan, causing the unit to overheat;
-
No maintenance in over 3 years, with heavy dust buildup on the coils.
Without immediate repair, the entire circuit risked burning out, leading to permanent damage to the central unit.
On-site restoration of the central air conditioner: fast and secure procedure
In under 2 hours, our technicians:
-
Replaced the defective fan;
-
Cleaned the condenser coils;
-
Reset the electronic control module;
-
Checked refrigerant levels (R-410A);
-
Reprogrammed the thermostat for optimized cycling.
By 1:55 p.m., the air conditioning system was running again, and the indoor temperature quickly stabilized at 23.5°C, without surges or excess noise.
Additional precautions implemented by AirGreen
Given the medical nature of the site, we ensured:
-
Full use of PPE to meet hygiene standards;
-
Only low-VOC cleaning products around sensitive areas;
-
Validation that there were no refrigerant leaks;
-
Delivery of a full intervention report to the pharmacist for insurance and health authority compliance.
Testimonial: instant relief for staff and patients
“We were about to shut down the pharmacy. The heat was unbearable, and we were afraid for the stability of our sensitive medications. The AirGreen team showed up fast, discreetly, and with outstanding efficiency. Thanks to them, we were able to continue serving our patients safely.”
