Optimize your winter comfort without breaking the bank thanks to smart commercial heating strategies
At AirGreen, we understand that every dollar counts for businesses in Montréal, Laval, Longueuil, the North Shore and the South Shore. When temperatures drop, commercial heating costs can quickly rise, putting a dent in your profitability. Fortunately, there are concrete, often overlooked ways to significantly reduce your energy expenses—without having to invest heavily in new equipment. Here are 5 surprising yet effective tips we often apply during our HVAC service visits with our commercial clients.
Improve insulation… without major renovations
Good insulation doesn’t necessarily mean big renovations. We've often advised building managers in Laval or Longueuil to optimize specific areas like door thresholds, utility hatches, or window frames. These small leaks can account for up to 30% of heat loss.
Our on-site advice:
-
Install adhesive weatherstripping on exterior doors.
-
Use thermal curtains in offices with exterior windows.
-
Close off rooms that are unused at night to limit thermal loss.
A local store in Montréal we assisted reduced its energy consumption by 12% simply by applying these adjustments.
Update your HVAC system’s programming
At AirGreen, we often notice that central heating systems operate on outdated schedules. In a warehouse in Boucherville, for example, the heating was still set to come on at 5 a.m.… even on holidays!
Our recommendation:
-
Review your system’s weekly heating schedule.
-
Avoid heating unoccupied areas: unused meeting rooms, warehouses at night, etc.
-
Integrate smart thermostats adapted to your real business hours.
This can lead to 15 to 20% savings on your annual bill—without spending a cent on equipment.
Maintain your heating system more strategically
Regular maintenance is essential, but more importantly, it must be targeted and tailored to your setup. At AirGreen, we adapt our maintenance procedures based on the age, model, and frequency of use of each system.
Why is this crucial?
-
A dirty heat exchanger reduces your unit's overall performance.
-
A simple filter cleaning can boost efficiency by 5 to 10%.
-
Early detection of refrigerant leaks prevents costly repairs.
Real example: In a business in Laval, we serviced a Haxxair central heat pump (48,000 BTU) that had lost 30% of its efficiency due to lack of maintenance. The result: full performance restored and an estimated $2,000 in annual savings.
Reorganize your space based on heat flow
This is one of the most counter-intuitive but often most effective tips. The way your space is laid out can greatly affect how heat circulates.
Tips we’ve applied:
-
Avoid placing tall cabinets or shelving in front of heating vents.
-
Use light partitions to channel heat toward key areas.
-
Arrange furniture in a way that takes air movement into account.
In a hair salon located in Saint-Eustache, these changes allowed us to lower the thermostat by 2°C while maintaining customer comfort—leading to an 18% reduction in energy use.
Get a targeted energy audit before any investment
A proper HVAC audit lets you prioritize actions without wasting money. At AirGreen, we offer tailored thermal audits for businesses and SMEs throughout the greater Montréal area.
What we analyze:
-
Heat distribution across the building.
-
Real vs. expected energy consumption.
-
Detection of hidden thermal leaks.
-
Technical recommendations based on local, real-life cases.
A restaurant in Longueuil avoided an unnecessary replacement of its Bosch central heat pump (60,000 BTU) thanks to a well-executed audit. All that was needed was optimizing airflow and reprogramming the heating cycle.
Why these tips work for our commercial HVAC clients

More often than not, operational adjustments and preventive maintenance yield the greatest gains.
