When a rapid HVAC cleaning saves a business from disaster in Montréal
In the bustling district of Villeray–Saint-Michel–Parc-Extension, a local restaurant owner in Montréal was facing a critical issue: their heating, ventilation, and air conditioning (HVAC) system had completely shut down in the middle of a heatwave. The indoor temperature in the dining area had become unbearable, customers were fleeing, and the staff could no longer keep up. The business’s survival was on the line.
That’s when they called AirGreen, known for its commercial HVAC cleaning services in Montréal and on the South Shore. Our intervention turned a desperate situation into an instant success.
Immediate diagnosis: a clogged, neglected system
As soon as we arrived, our team of certified technicians carried out a comprehensive diagnosis of the HVAC system:
-
The air filters were clogged with dust and cooking grease.
-
The ventilation ducts emitted a strong smell of moisture.
-
The coils of the air conditioning units were blocked with residue and mold.
-
The air return system was no longer functioning properly, causing stagnant hot air.
These problems weren’t caused by mechanical failure but by a lack of regular maintenance. The owner, caught up in the daily demands of running a restaurant, had never considered having the HVAC system cleaned since its installation over five years ago.
Complete, fast, and effective HVAC cleaning implementation
At AirGreen, we understand that a business can’t afford to shut down for long. So, we planned and executed an emergency HVAC cleaning, after business hours, to minimize the impact on sales.
Steps of our intervention:
-
Cleaning and replacing the air filters with high-quality commercial HEPA models.
-
Degreasing the coils using a high-performance biodegradable cleaner.
-
Thorough duct cleaning using our negative-pressure equipment.
-
Antibacterial and antifungal treatment of the ventilation system.
-
Disinfection of air grilles and indoor units.
-
Cleaning the outdoor unit, often neglected, but crucial to the system’s overall performance.
Our team completed the entire operation in one night, with full service restored by the next morning.
Measurable results within hours
Upon reopening, the effects of the cleaning were immediate:
-
Indoor temperature stabilized at 22°C, even during peak hours.
-
Noticeable improvement in air quality, confirmed by sensors placed in the dining room.
-
Noise reduction from indoor units, indicating smooth operation.
-
Estimated energy savings of 18% due to system optimization.
The owner quickly noticed an increase in foot traffic, and several regular customers even commented on the restored ambiance.
“It’s like my restaurant is breathing again. I didn’t realize how much of a difference HVAC maintenance could make,” he told us.
What this case shows about HVAC cleaning
This case clearly illustrates the impact of neglected HVAC maintenance, and on the flip side, the immediate benefits of a thorough cleaning carried out by experts. In environments like restaurants, where air quality, temperature, and silence are essential to the customer experience, HVAC cleaning must be a priority, not an option.
