Mastering Commercial Heating in Montréal: A Matter of Precision, Resilience, and Expertise
In Montréal, where harsh winters leave no room for error, commercial heating becomes much more than a simple technical requirement — it’s a matter of comfort, safety, and operational continuity. At AirGreen, we regularly face complex challenges tied to heating commercial buildings, whether in downtown office towers, industrial buildings on the South Shore, or community centers in Laval. Here’s a deep dive into the 5 most common challenges we encounter in the field and the real solutions we’ve implemented to deliver reliable, energy-efficient commercial HVAC heating service.
1. Adapting the Heating System to an Old or Heritage Structure
The Challenge: Complex and Unpredictable Infrastructure
Many commercial buildings in Montréal — especially in areas like the Plateau or Old Montréal — have inadequate insulation, outdated ductwork, or original heating systems. Installing or upgrading a central heating system in these environments requires advanced expertise.
Our Solution
We always carry out a complete thermal assessment using infrared cameras and digital diagnostic tools. For example, in a recent project in Outremont, we installed a high-efficiency Bosch central condensing boiler in a century-old building. Thanks to an intelligent zoning system, each floor is now independently controlled, optimizing both comfort and energy savings.
2. Ensuring Even Heating Across Large Areas
The Challenge: Uneven Heat Distribution
In warehouses or large commercial spaces in Laval or the North Shore, heating can be inconsistent, leading to cold zones or excessive energy consumption.
Our Solution
We deploy forced air systems combined with thermal air curtains, which are particularly effective in loading areas or industrial halls. One of our North Shore projects for a logistics company required the installation of 15-ton Trane rooftop units, paired with smart thermostats, ensuring consistent temperature even in the most remote corners.
3. Meeting Energy and Environmental Standards
The Challenge: Energy Performance and Grants
Energy standards in Québec are getting stricter, particularly for commercial buildings with high energy use. Many clients are also looking for energy-efficient solutions to qualify for provincial or federal subsidies.
Our Solution
At AirGreen, we prioritize the installation of commercial central heat pumps, like the Bosch BOVA IDS Premium R-454b models, which are highly efficient even at -20°C. Recently, a retail business in Longueuil chose this solution and received an $8,000 grant through the LogisVert program, while reducing its heating bill by 34% in a single winter.
4. Minimizing Disruptions During Installation Work
The Challenge: Maintaining Operational Continuity
Businesses and companies cannot afford prolonged interruptions, especially during peak hours. Heating system installations or replacements must be fast, discreet, and well-coordinated.
Our Solution
Our teams plan overnight or weekend interventions, and we pre-assemble all modules off-site. For example, during an intervention in a 24/7 supermarket in Brossard, we replaced an obsolete oil heating system with a FUJITSU KZAH R-32 central heat pump in under 48 hours — without interrupting business operations.
5. Managing Multi-Tenant Systems with Distinct Needs
The Challenge: Meeting Different Thermal Needs in the Same Building
In multi-tenant commercial or office buildings, each space may have different requirements. Some tenants want more heat, others less, and traditional systems struggle to keep everyone happy.
Our Solution
We install Variable Refrigerant Flow (VRF) systems with multiple indoor units. These systems allow for individual temperature control in each space. In a building in Saint-Lambert, we installed a Mitsubishi Electric VRF system with 12 wall-mounted units spread across various commercial spaces — the result: satisfied tenants, significantly fewer complaints, and easier management for the property owner.
The AirGreen Approach: Expertise, Responsiveness, Customization
Beyond the technical know-how, what sets us apart is our human, thorough, and strategic approach. Every project is treated as a unique case.
