AirGreen recently had the opportunity to provide refrigeration system repair and maintenance services for a local store in the Mercier–Hochelaga-Maisonneuve borough. This service call was another step in our mission to ensure that businesses in Montréal, Laval, Longueuil, and surrounding areas have access to top-tier HVAC solutions tailored to their specific needs.
When we received the call, the customer informed us of a malfunctioning refrigeration unit that was crucial for their daily operations. In cases like these, immediate action is essential to prevent inventory loss and maintain the store’s ability to serve its customers.
The Situation: A Cooling Crisis in a Local Store
Located in the heart of Mercier–Hochelaga-Maisonneuve, this convenience store relied heavily on its commercial refrigeration system to keep products at optimal temperatures. When the system began to show signs of failure—temperatures fluctuating, unexpected shutdowns—it became clear that a professional intervention was needed.
We dispatched our experienced technicians to diagnose and repair the refrigeration unit. Upon arrival, our team was greeted with a situation where the refrigeration system was struggling to maintain the required temperature. Without a fully functional system, the store was at risk of spoilage and potential revenue loss.
The Diagnosis: Troubleshooting the Refrigeration Unit
Upon inspection, it became evident that the compressor and evaporator fan motor were underperforming. This can happen due to a variety of factors, including wear and tear, inadequate maintenance, or electrical faults. The initial temperature reading showed that the system was operating at 2.1°C, which was above the desired range for most refrigeration applications. Additionally, the compressor was making unusual noises, a clear indicator of internal mechanical issues.
Using advanced diagnostic tools, including infrared thermometers, our team identified the root cause: an accumulation of ice on the evaporator coils, which was preventing the system from reaching optimal efficiency. The fan motor was also functioning intermittently, further exacerbating the problem.
The Repair: Restoring Functionality
Once the issues were identified, we began a thorough cleaning of the evaporator coils to ensure they were free of ice buildup. Next, we repaired the faulty compressor by replacing essential components that had worn out over time. We also addressed the issue with the fan motor, replacing it with a high-efficiency model that ensured consistent airflow across the coils.
Our team also performed a complete check of the refrigerant levels to make sure the system was not undercharged, which is a common cause of suboptimal cooling performance. We topped off the refrigerant where necessary, ensuring that the system could maintain the required temperatures moving forward.
Why Maintenance is Crucial for Refrigeration Systems
This job highlighted the importance of regular maintenance for refrigeration systems. Over time, even the most reliable equipment can experience wear and tear, leading to potential breakdowns. In this case, the store had not conducted routine maintenance checks, which allowed the issues to escalate.
At AirGreen, we recommend preventive maintenance to all of our commercial clients. By scheduling regular inspections, businesses can avoid unexpected failures and extend the lifespan of their refrigeration systems.
Key Maintenance Tasks:
- Evaporator Coil Cleaning: Prevents ice buildup and maintains airflow.
- Compressor Checks: Ensures the heart of the system is functioning efficiently.
- Refrigerant Level Checks: Keeps the system operating within its designed parameters.
- Fan Motor Inspections: Ensures consistent airflow across the system.
The Outcome: A Fully Restored Refrigeration System
After our repair and maintenance services, the store's refrigeration system was restored to full functionality. The internal temperature was back to its optimal level, keeping products safe and fresh for customers. The store owners were highly satisfied with the quick response and professional service, knowing that their refrigeration unit was now in better shape than ever.
By the end of our service call, the refrigeration system was holding steady at -2.5°C, a significant improvement over the initial temperature readings. This allowed the store to continue operations without any further risk of spoilage or product loss.
