Frequent heating mistakes that cost Montréal retailers more than they think
In Montréal, the performance of a heating system in retail spaces is a critical factor—not only for customer comfort but also for the store’s overall profitability. At AirGreen, we’re often called in to service retail shops across Montréal, Laval, Longueuil, the North Shore and South Shore that are struggling with poor system configurations or neglected HVAC maintenance. Here are the five most frequent mistakes we see—and more importantly, how to avoid them with a professional, tailored approach.
Mistake #1: Neglecting regular HVAC maintenance
In many retail stores, lack of regular heating system maintenance is the number one cause of failures during the winter season. Clogged filters, worn-out parts, or blocked ducts directly impact the system’s energy performance.
Consequences:
-
Excessive energy consumption
-
Unexpected breakdowns during peak business hours
-
Reduced lifespan of the equipment
AirGreen solution:
We offer a preventive HVAC maintenance program designed specifically for retail businesses, including cleaning, inspection of key components, and thermostat calibration to ensure year-round optimal performance.
Mistake #2: Installing a heat pump or furnace with the wrong capacity
A common mistake is installing a heating unit that is either oversized or undersized. This results in poor temperature regulation, short cycling, premature wear of components, and overall discomfort for customers.
Real example in Laval:
A fashion retailer was operating with a furnace that was too powerful for the space. The result: constant temperature fluctuations, customer complaints, and skyrocketing heating bills.
Our solution:
We installed a Lennox ML196E heat pump, 60,000 BTU, perfectly sized to the store’s surface area, along with a revised air distribution layout. Comfort levels stabilized, and energy costs dropped by 22% within a year.
Mistake #3: Ignoring hot and cold spots in the space
Many retailers overlook temperature variations from one area to another, often caused by poor duct layout or lack of zoning sensors in certain sections of the store.
Warning signs:
-
Customers complaining about drafts near the entrance
-
Employees using space heaters
-
Temperature-sensitive food sections exposed to unstable climate
AirGreen approach:
Through a full thermal audit, we reconfigure the heat distribution layout and install independent zone controls (multi-zone thermostats), ensuring consistent and controlled temperature throughout all store areas.
Mistake #4: Missing out on available government grants
Too many retailers still don’t realize they’re eligible for significant rebates on HVAC system upgrades, especially through Hydro-Québec’s LogisVert program or other municipal incentives.
Result:
-
Delays in upgrading inefficient systems
-
Higher upfront costs without financial aid
-
Missed opportunities to cut energy use
Our support:
At AirGreen, we assist every client in completing their grant applications and selecting eligible high-efficiency equipment, such as wall-mounted heat pumps with SEER 20+, while guaranteeing certified installation.
Mistake #5: Not adjusting system settings to match store hours
Your heating setup should reflect the store’s actual operating schedule. Without proper programming or a smart timer system, you’ll end up wasting energy when the store is closed.
Real case in Longueuil:
A bakery was heating at full capacity from 5 a.m. to 9 p.m., even when no staff were present from 2 p.m. to 4 p.m. After our intervention, we implemented a precise hourly programming system, which helped reduce their energy bill by 18%.
The AirGreen solution:
We install connected smart thermostats, allowing detailed control over heating schedules, outdoor temperature adaptation, and remote management by the store manager.
