A Strategic Decision for the Performance of Your Commercial Heating System
Choosing the right contractor for your commercial heating maintenance in Montréal, Laval, Longueuil, North Shore and South Shore is far from a simple formality. It’s a crucial decision that directly impacts not only the longevity of your HVAC system, but also your operating costs, indoor comfort, and even regulatory compliance. At AirGreen, we understand just how high the stakes are in the commercial sector. That’s why we’re offering you this comprehensive, strategic guide—built from real field experience—to help you ask the right questions and make an informed decision.
Why Commercial Heating Maintenance Is a Key Performance Lever
A poorly maintained commercial heating system can quickly become a source of costly breakdowns, excessive energy consumption, and even regulatory non-compliance. Whether you manage an office building in Laval, own a retail space in Longueuil, or oversee a school on the South Shore, the right contractor ensures:
-
Optimal energy performance
-
Extended lifespan of your equipment
-
A significant drop in emergency service calls
-
Better predictability in operating costs
1. Do They Have Specific Expertise in Commercial Heating Systems?
Not all HVAC contractors are created equal—especially when it comes to commercial systems. It’s essential to confirm that the company has documented experience in maintaining high-capacity heating systems such as rooftop units, gas furnaces, commercial boilers, or hydronic systems.
At AirGreen, our team regularly services systems from brands such as Goodman, Trane, Lennox, Carrier, Bosch, Fujitsu, and Haxxair, with full technical expertise on the particularities of each type of installation.
Real-life example: For a sports complex in Laval, we recently completed a full preventive maintenance on a 20-ton Lennox rooftop system. The result? A 15% improvement in energy efficiency, early detection of a faulty sensor, and zero breakdowns during the winter season.
2. Do They Offer Preventive Maintenance Contracts Tailored to Your Needs?
A good contractor will offer you a customized maintenance contract, designed around your actual needs, building type, and occupancy schedule. Be cautious of “one-size-fits-all” packages that don’t account for your specific realities.
At AirGreen, our maintenance contracts typically include:
-
Two to four preventive visits per year
-
A service schedule aligned with your business cycles
-
Detailed inspection reports
-
Priority response for emergency service calls
Pro tip: Ask whether the contract includes periodic filter replacement, heat exchanger inspection, and full duct cleaning.
3. Are Their Technicians Certified and Continuously Trained?
Maintaining commercial heating systems requires advanced technical skills. Make sure the technicians are:
-
Certified by Emploi-Québec
-
Trained on the latest technologies (natural gas, high-efficiency systems, smart sensors)
-
Familiar with ASHRAE, CSA standards, and local regulations (e.g., emissions rules in Montréal)
At AirGreen, our technicians undergo ongoing training and are regularly evaluated in real-life scenarios. Every maintenance visit follows a strict verification protocol, complete with photos and supporting documentation.
4. Do They Have a Proven Track Record and Verifiable References in Your Sector?
A good contractor is measured not by promises, but by real-world experience. Ask for specific references—ideally in the same industry or building type as yours.
Recent AirGreen examples:
-
Annual maintenance of heating systems for a 120-unit residential complex in Montréal
-
Full preventive service for a high school on the North Shore, including combustion analysis
-
Proactive maintenance of a refrigerated warehouse on the South Shore with centralized control systems
5. Is Their Approach Proactive or Merely Reactive?
Many contractors only step in when something goes wrong. While this may seem economical short term, it’s often risky and expensive in the long run.
At AirGreen, we believe in a proactive approach. During every maintenance visit, we anticipate failures, recommend improvements, and fine-tune settings to maximize energy efficiency. This philosophy allows us to reduce emergency service calls by 40% among our contract clients.
6. Do They Provide Personalized Advice and Stay on Top of New Technologies?
Maintenance should go beyond checking filters. A good contractor should also advise you on possible upgrades, new technologies, and available grants.
For example:
-
Switching from an old gas system to a high-efficiency central heat pump eligible for the LogisVert program
-
Adding smart multizone control systems to improve comfort and reduce consumption
-
Adjusting your equipment to meet Montréal’s new emissions regulations
AirGreen also helps you with building energy management and grant applications, with deep knowledge of Hydro-Québec, Transition énergétique Québec, and other local incentive programs.
