Optimize your commercial heating system’s performance without compromise
In a context where energy costs continue to rise, it's crucial for businesses in Montréal, Laval, Longueuil, the North Shore, and the South Shore to optimize every aspect of their commercial heating systems. At AirGreen, we know that regular maintenance of a commercial heating system is not only essential to ensure occupant comfort, but also to significantly reduce long-term expenses. With our field experience and expertise in HVAC, we’re sharing our top professional tips to lower your maintenance costs while extending the life of your equipment.
Preventive maintenance: the cornerstone of economical commercial heating
The first tip – and undoubtedly the most cost-effective – remains regular preventive maintenance. Too many businesses wait for a problem before calling a technician. However, a simple annual HVAC maintenance contract helps avoid most expensive breakdowns.
What proper preventive maintenance includes:
-
Full inspection of all units (boiler, central heat pump, warm air generator, etc.)
-
Cleaning of filters, coils, and ducts
-
Electrical connection and motor inspection
-
Thermostat and sensor calibration
-
Refrigerant or natural gas level checks
Proper maintenance increases the energy efficiency of the equipment, which directly translates into substantial savings on energy bills.
Real-life case: 22% cost reduction for a commercial building in Laval
One of our clients, a commercial property manager in Laval, was facing high monthly heating expenses. After setting up a maintenance program with AirGreen, including quarterly inspections of their Bosch BOVA central heat pump, we identified an airflow imbalance caused by partially blocked ducts. Result: immediate comfort improvement and a 22% reduction in energy consumption over a six-month period.
Use high-quality filters and replace them regularly
A clogged filter seriously impacts a heating system’s performance. It causes increased energy consumption, inadequate heating, and speeds up wear and tear on components.
Our recommendations:
-
Replace filters every 2 to 3 months, depending on the environment (more frequently in industrial settings)
-
Use high-efficiency filters rated MERV 11 or higher
-
Set up a visible maintenance calendar in the mechanical room
This simple tip can save up to 10% on annual energy bills while extending your equipment’s lifespan.
Invest in a modern, energy-efficient central heat pump
Sometimes, maintenance is no longer enough when the equipment is outdated. Upgrading to a high-efficiency central heat pump is a strategic investment.
Recommended models for commercial heating:
-
Fujitsu KZAH R-32: excellent performance in cold climates, compatible with existing ductwork
-
Bosch BOVA IDS Premium R-454B: inverter technology, extremely low energy use during peak times
-
Goodman GSZC18: great value, durable and robust, ideal for medium-sized commercial buildings
New units are often eligible for government grants, particularly in Montréal and on the South Shore, helping reduce the initial cost.
Optimize heating management with smart automation
Automated control systems allow you to remotely manage operating hours, target temperatures, and quickly detect any malfunctions.
Our solutions include:
-
Multi-zone programmable smart thermostats
-
Integration with HVAC automation systems
-
Email or SMS alerts in case of anomalies
When properly installed by our team, these technologies enable an average reduction of 15 to 30% in commercial heating costs.
Always rely on commercial heating specialists for every service call
It’s essential that all interventions, even the simplest ones, are performed by certified commercial HVAC technicians. At AirGreen, our teams are trained to meet the specific requirements of commercial buildings: large surface areas, zone-based needs, fire safety, energy compliance, and more.
Installation example: Gree central heat pump in Longueuil
A client located in Longueuil contacted us to replace an old, inefficient gas system. We recommended and installed a 5-ton Gree Flexx central heat pump, combined with a 4-zone zoning system. The installation was completed in three business days, without disrupting commercial operations. Since then, the client has seen a 28% drop in heating costs and qualified for a $6,580 LogisVert grant.
Thermal analysis and airflow balancing: an often-overlooked step
Proper airflow balancing in a building is essential. Too often, certain zones are overheated while others remain cold, forcing the system to overcompensate unnecessarily.
Our services include:
-
Thermal analysis using infrared cameras
-
Duct pressure testing
-
Air register calibration
These adjustments may seem minor, but they lead to greater comfort and more even energy consumption.
Schedule your maintenance before the cold season
A large number of breakdowns occur during the first weeks of winter usage. We recommend scheduling your maintenance at the end of summer or early fall, when our schedules are more flexible and parts are readily available.
At AirGreen, we offer customized maintenance plans for commercial spaces, SMEs, schools, warehouses, and mixed-use buildings. Our interventions are fast, discreet, and always carried out in compliance with safety and energy efficiency standards.
