Optimize your commercial heating system with a targeted inspection
In a commercial setting, the energy efficiency of the heating system is a critical factor not only for occupant comfort but also for the profitability of the business. In Montréal, Laval, Longueuil, as well as on the North Shore and South Shore, harsh winters put significant strain on commercial heating systems. Yet many sources of energy loss go unnoticed, unnecessarily increasing operating costs. At AirGreen, we’ve developed a thorough method to quickly identify energy loss and optimize all your HVAC equipment.
Why is energy loss in commercial heating systems so common?
In commercial buildings — whether offices, warehouses, retail stores, or multi-unit dwellings — the causes of heat loss are often numerous: poor insulation, miscalibrated HVAC systems, air infiltration, failing components, and more. A simple malfunction in a ventilation duct or a defective valve can lead to significant energy waste.
Early signs of an inefficient heating system to watch for
Even before a technical audit, certain signs can raise red flags:
-
Consistently rising energy bills, especially during winter months
-
Persistent cold zones in certain areas despite the system running
-
Longer heating times than usual
-
Cold drafts near windows or doors
-
Unusual noises or irregular operation from your heating units
Practical steps to detect energy loss in your heating system
1. Full visual inspection of heating components
Our technicians begin with a visual inspection of all HVAC equipment: boilers, central heat pumps, electric baseboards, ductwork, heat exchangers, smart thermostats. Any signs of rust, corrosion, water leaks, or debris are thoroughly documented.
2. Analysis of ducts and ventilation system
Poorly sealed ductwork is one of the most frequent causes of heat loss. We use specialized tools to:
-
Detect air leaks in both metal and flexible ducts
-
Measure airflow at each ventilation grille
-
Ensure the system is properly balanced between different building zones
3. Infrared thermography: detecting the invisible
Using a thermal imaging camera, we detect:
-
Thermal loss zones (roofs, walls, floors)
-
Thermal bridges caused by poor insulation
-
Presence of moisture that can weaken thermal performance
This method allows us to map heat loss in real-time without demolishing or opening up structures.
4. Combustion testing and appliance efficiency
For combustion systems (oil, natural gas), a combustion test helps measure:
-
The actual energy efficiency of the boiler
-
The oxygen level in combustion gases
-
The flue gas temperature (an indicator of loss through the chimney)
An efficiency below 85% is often a clear sign that maintenance or replacement is urgently needed.
5. Thermostat programming and calibration
A poorly calibrated thermostat can overheat certain areas, driving up consumption. We check:
-
The optimal positioning of the thermostat
-
The temperature probe calibration
-
Programming according to building occupancy schedules
Case study: Energy audit of an office complex in Laval
A commercial client in Laval contacted us due to excessively high heating bills. After a full inspection of their central gas system and ventilation, we identified:
-
Three major leaks in the main ducts
-
A boiler operating at only 76% efficiency
-
Poor thermal insulation in the roof
-
Unprogrammed thermostats causing unnecessary nighttime heating
After duct repairs, system optimization, complete calibration, and installation of smart thermostats, the energy bill dropped by 28% in just three months.
Practical tips to avoid energy loss in your commercial heating
-
Schedule preventive HVAC maintenance every fall
-
Properly insulate attics, floors, and exterior walls
-
Replace outdated equipment with high-efficiency systems
-
Use programmable smart thermostats
-
Monitor heating bills and compare year-over-year data
