A commercial heating system is often seen as a basic, functional piece of equipment, but it holds many hidden complexities that even experienced building managers or business owners don’t always realize. At AirGreen, our job is not only to install and maintain high-performance commercial heating systems across Montreal, Laval, Longueuil, South Shore and North Shore, but also to educate our clients so they can make the best decisions when it comes to commercial HVAC solutions. Here are eight surprising facts that might just change how you see these essential systems.
1. Commercial heating systems are rarely “one-size-fits-all”
Contrary to popular belief, there is no universal solution that works for all commercial buildings. Every project is different: square footage, insulation quality, occupancy levels, type of activity (restaurant, office, warehouse), high or low ceilings, humidity levels... All these factors influence whether a forced-air system, a central heat pump, or a condensing boiler is the right choice.
At AirGreen, we always perform a thorough technical assessment before any installation to recommend a truly customized setup. Proper sizing helps optimize energy consumption and prevents premature wear on the equipment.
2. A poorly designed system can make your energy bills skyrocket
Even if a system seems high-performing on paper, a poor design can waste thousands of dollars in energy each year. Improperly sized ductwork, poorly positioned thermostats, or inefficient airflow management can create cold spots or overheated zones, causing the equipment to overwork.
That’s why we pay close attention to duct layout, control system quality, and zone management strategies, to ensure even heat distribution and long-term efficiency.
3. There are grants available for commercial heating systems… but few people know about them
Many businesses don’t realize they may qualify for financial assistance programs aimed at improving heating systems. For example, Hydro-Québec’s LogisVert program, typically associated with residential properties, also includes commercial components for eligible buildings.
We support our clients throughout the process — from assessing eligibility to preparing the paperwork — which can significantly reduce the investment required for an energy-efficient heating upgrade.
4. Commercial heat pumps work — even in Québec winters
Many people still think heat pumps become ineffective below -15°C. In reality, several modern models — especially from brands like Bosch, Fujitsu or Gree — remain efficient down to -30°C, sometimes lower. These high-performance commercial heat pumps can comfortably heat a business in the heart of January, while lowering reliance on gas or electricity.
We regularly install wall-mounted or central heat pumps in businesses on the South Shore, in Laval, and downtown Montreal, with impressive results when it comes to lowering annual heating costs.
5. Radiant heating is gaining traction in warehouses and industrial buildings
Radiant heating, whether in-floor or via suspended infrared units, is becoming increasingly popular in industrial buildings and warehouses. Why? Because it heats objects and people directly, not the air, making it especially effective in large open spaces.
We recently installed an infrared tube radiant heating system in a 9,000 sq. ft. warehouse in Boisbriand (North Shore), which led to a 37% reduction in heating costs during the very first season.
6. Preventive maintenance costs less than emergency repairs
Many commercial building owners delay HVAC maintenance until something breaks. But routine commercial maintenance is significantly cheaper than unexpected replacements or winter breakdowns.
At AirGreen, we offer custom commercial HVAC maintenance contracts in Montreal, Laval and Longueuil, including inspections, filter cleaning, heat exchanger checks, and thermostat calibration.
7. Modern systems offer smart, remote control options
Today’s commercial heating systems allow for centralized, intelligent, and remote management through platforms like Ecobee for Business or Honeywell Building Management.
This means a building manager can use their phone or computer to adjust temperature settings, monitor consumption, detect issues, or automate operating schedules — a major advantage in terms of comfort and energy efficiency.
8. Warm air isn’t enough: ventilation and air quality matter just as much
A good commercial heating system does more than produce heat. It should also include proper ventilation, filtration, and humidity control. Air that’s too dry or poorly filtered can negatively affect employee well-being, customer health, and workplace productivity.
In our projects, we frequently install energy recovery ventilators (ERVs or HRVs), MERV 13+ filters, and even UVC air purifiers in sensitive environments like clinics, daycare centers, and restaurants.
Field expertise: notable installations from AirGreen
At AirGreen, we’ve installed dozens of commercial heating systems tailored to the specific needs of various buildings:
-
In Longueuil, a 5-ton Bosch BOVA central heat pump, with multizone zoning and Wi-Fi interface.
-
In Montreal, at a Plateau café, a Viessmann wall-mounted condensing boiler paired with a balanced mechanical ventilation system.
-
In Laval, a refrigerated warehouse was outfitted with a Reznor infrared radiant heating system, with precision thermostats for each section.
These installations show our ability to match our solutions to each business’s operational reality, while maximizing return on investment for our clients.
