A commercial air conditioning system without regular maintenance is a breakdown waiting to happen
In the commercial world, a high-performing air conditioning system is not a luxury—it’s a business necessity. Whether it’s for a boutique in Montreal, a restaurant in Laval, or an office on the South Shore, the reliability of your commercial air conditioning directly impacts employee comfort, customer experience, and sometimes even the preservation of sensitive products. Yet too many businesses still overlook one critical aspect: the regular maintenance of their air conditioning system.
From our experience at AirGreen, 80% of breakdowns we observe in HVAC systems could have been avoided with proper preventative maintenance. Here’s why this simple habit can transform your day-to-day business operations.
The real impact of preventative maintenance on commercial air conditioning
Protection against costly interruptions
A commercial AC failure during a heatwave can result in temporary closures, loss of revenue, decreased productivity, and emergency repair costs that far exceed the price of regular maintenance. In Montreal and Longueuil, we’ve seen businesses forced to pause operations while waiting for a hard-to-source part or a full compressor replacement.
A simple coil cleaning, replacing clogged filters, or checking refrigerant levels would have been enough to avoid these shutdowns.
Optimized energy performance
A poorly maintained system quickly loses efficiency: dirt buildup, dry or misaligned parts, blocked filters… The result? Your air conditioner consumes more energy while delivering poorer performance. In Laval, a restaurant client saw their energy bill drop by 22% after a complete maintenance of their multi-zone Fujitsu system.
Extended equipment lifespan
A commercial air conditioner is a major investment. Without regular maintenance, you shorten its lifespan by several years. By taking proper care of your system, you avoid premature replacements, extend manufacturer warranties, and maximize your HVAC return on investment.
What professional HVAC maintenance includes with AirGreen
Full system inspection
At AirGreen, we inspect all components: compressor, ducts, evaporators, condensers, thermostats, and more. This step allows us to detect early signs of wear or imbalance.
Deep cleaning
Indoor and outdoor units are cleaned and disinfected, filters are replaced or cleaned, and fins are straightened for optimal airflow. We use non-corrosive products that are safe for commercial environments.
Refrigerant level check and performance testing
We measure gas levels, detect potential leaks, and adjust everything to meet Quebec’s environmental standards. An unbalanced refrigerant level severely reduces the efficiency of your system—especially in high-performance models like Gree, Lennox, or Bosch.
Thermostat and controller calibration
Poor thermostat programming can lead to overheating or overcooling your spaces. We calibrate smart, centralized, or individual thermostats to ensure consistent comfort and efficient energy use.
Case study: A food store in Saint-Jérôme saved from a major breakdown
In the summer of 2024, a food retailer on the North Shore called us: their 5-ton Trane central air system stopped working during an extreme heatwave. The result? Perishable goods at risk, stressed staff, unhappy customers.
When we arrived for the emergency repair, we found mold buildup on the coils, a saturated filter, and low refrigerant pressure. These issues would never have developed if a yearly maintenance plan had been in place. Since then, the client has signed up for a quarterly maintenance contract. No breakdowns since.
Common mistakes to avoid when it comes to HVAC maintenance
-
Waiting for the system to show signs of failure (by then, it’s often too late)
-
Relying on uncertified staff for maintenance
-
Neglecting the outdoor unit: leaves, debris, snow, ice… a real problem magnet
-
Assuming new models don’t need maintenance (on the contrary, they’re more sensitive to imbalance)
