A rapid HVAC service call to save a local business from shutting down
In the field of commercial HVAC in Laval, some emergencies require absolute reactivity. When a heatwave hits hard across the region, small local shops must maintain a comfortable environment for both their customers and staff. That’s exactly what happened when a specialty grocer located on boulevard Curé-Labelle in Laval called us in the middle of a July heatwave. Their wall-mounted heat pump had completely stopped producing cool air, and indoor temperatures had risen above 30°C. At AirGreen, we know that in situations like these, every hour counts.
Context: a wall-mounted air conditioner breakdown in a food retail shop
The client, owner of a specialty grocery store, called us on a Wednesday morning at 9:30 a.m. According to him, his FUJITSU wall-mounted heat pump (model ASYG18KMTC, 18,000 BTU) had stopped working the previous evening. In the peak of summer, this issue threatened product quality, customer experience, and team morale.
As soon as we got the call, our emergency HVAC response team in Laval restructured the day’s schedule to send two certified technicians on site before noon. The goal: diagnose and repair the unit the same day, minimizing any business loss.
Fast and accurate diagnosis: a failed control module
Our technicians arrived by 11:45 a.m. and immediately inspected both the indoor and outdoor units. The FUJITSU wall-mounted A/C was blinking a fault code, indicating a communication issue between the circuit boards. Within 30 minutes, the diagnosis was clear: the indoor unit’s control board was fried, likely due to a recent power surge.
Fortunately, thanks to our local stock of FUJITSU heat pump parts in Laval, we had the required module on hand, allowing us to proceed with the repair immediately, with no waiting time for part delivery.
Repair completed in under 2 hours, including a full unit cleaning
The repair took place in three key steps:
-
Safe disassembly of the wall unit and removal of the damaged board.
-
Installation of the new control module, system reset, and full function testing.
-
Deep cleaning of the coils, filters, and drain, to prevent future condensation or clogging issues.
By 2:30 p.m., the A/C system was back to full operation. The store’s interior temperature quickly dropped to a comfortable 22°C, much to the relief of the staff and customers.
