Ensuring optimal performance and maximum lifespan for commercial air conditioning systems is a critical responsibility for any business in Montréal, Laval, Longueuil, on the North Shore or the South Shore. Yet too often, annual maintenance is seen as an optional extra — postponed or ignored… until a major issue arises. At AirGreen, we know from experience that regular preventive maintenance isn’t a luxury — it’s a strategic operational and financial necessity.
Real-World Insight: The Consequences of Neglected Air Conditioning
In many commercial buildings — from small corner shops to multi-storey office towers — we’ve seen the same recurring problems: clogged filters, dirty coils, overworked compressors, or jammed fans. These issues, all preventable with annual maintenance, can lead to:
-
Up to 30% higher energy consumption
-
Unexpected costly breakdowns
-
A shortened equipment lifespan
-
Reduced comfort for occupants
-
Non-compliance with indoor air quality standards
Take a recent case in Longueuil: a medical clinic equipped with a 15-ton Trane system had skipped maintenance for two years. The result? A premature replacement of the outdoor condenser, costing nearly $9,000. Annual maintenance would have cost less than $400 per year.

Why Annual Maintenance Is a Smart Investment for Your Business
The most common mistake among property managers is believing maintenance is an avoidable expense. In reality, it’s a strategic investment. Every dollar invested in maintenance can generate between $3 and $5 in savings over time, notably through:
-
Direct reduction in energy costs
-
Avoidance of major repairs or premature replacements
-
Preservation of manufacturer warranties
-
Greater customer and employee satisfaction thanks to consistent thermal comfort
A Standout Example: Annual Maintenance of a Lennox System in Laval
Last year, we handled the annual maintenance of a 20-ton Lennox rooftop system installed on a commercial building in Laval. The unit served a high-end gym operating seven days a week. Our technicians detected a minor leak in the condensate drainage line — invisible to the naked eye — that could’ve caused water infiltration and damage to the drop ceiling. Thanks to our quick intervention, the issue was resolved immediately — with no disruption to the client’s operations.

What You Risk Without Regular Maintenance
This isn’t just about optimization — it’s about avoiding major problems. Here’s what we’ve seen all too often with clients who delayed maintenance:
-
Complete system shutdown during a heatwave in July in Montréal
-
Mold inside air ducts due to built-up humidity
-
Equipment degradation from undetected rust and corrosion
-
Abnormally high electricity bills during the summer
Québec’s Climate: A Complicating Factor
The extreme temperature swings in our region, combined with the heavy use of heating and cooling systems in commercial buildings, increase wear and tear. A rigorous annual maintenance plan, tailored to Québec’s climate, is even more essential here than elsewhere.
