VRF technology adapted to Quebec’s harsh winters

At AirGreen, we offer complete HVAC installation and maintenance solutions to meet the specific needs of businesses and residential buildings in Montreal , Laval , Longueuil , the North Shore and the South Shore . The Lennox Cold Climate VRF Varix Extreme | 24 Tons | Parts by Samsung represents a major step forward for owners and managers who want to optimize the comfort and energy consumption of their buildings, without compromising on reliability or winter performance. Here, we present an in-depth analysis of this system, its real-world benefits in the field and how AirGreen ensures its optimal integration.

Context of use in a Quebec climate

Quebec winters require efficient heating solutions capable of maintaining optimal indoor conditions when the mercury drops below -30°C. The Lennox Cold Climate VRF Varix Extreme stands out in particular for its ability to provide 100% heating down to -22°F (approximately -30°C) thanks to refrigerant reinjection technology. This feature overcomes the difficulties encountered by many standard heat pumps, whose performance drops sharply below -15°C.

In the greater Montreal area, where we have installed several VRF systems, commercial or multi-residential buildings often have a high energy consumption profile during the cold season. By intelligently integrating this system into your installation, you can reduce operational costs while maintaining a constant, comfortable temperature for occupants. Buildings located on the North Shore or on the outskirts of Longueuil also benefit from the same advantages, particularly due to stable performance even in areas exposed to strong cold air currents.

VRF logic: modular and energy-efficient operation

VRF (Variable Refrigerant Flow) technology is based on intelligent modulation of refrigerant flow based on actual demand in each zone of the building. The Lennox Cold Climate VRF Varix Extreme features a digital inverter compressor, capable of precisely adjusting its speed to maintain a stable temperature without over-consumption. This approach allows for:

• Regulate performance : The system runs at full capacity only when it detects high demand. It reduces its speed when heating or cooling needs are lower.

• Reduce consumption : Continuous adjustment of the refrigerant flow rate avoids sudden starts and stops that cause peaks in electricity consumption.

• Ensure tailored comfort : Each zone benefits from independent regulation. This makes it easy to create distinct thermal environments, for example, for one floor exposed to the sun and another located in the shade.

At AirGreen, we have already installed VRF systems in office buildings in Montreal , where occupancy rates vary from floor to floor. Facility managers appreciate the flexibility offered by zoning and the resulting overall efficiency. In one project on the South Shore , a building complex was able to reduce its annual energy bill by more than 20% by switching from a traditional system to a Cold Climate VRF.

Concrete benefits for property managers

1. Energy savings : VRF technology significantly reduces long-term costs. Our customers in Laval report noticeable reductions in energy bills, especially during the winter.

2. Increased occupant comfort : In a commercial building, thermal comfort influences productivity and employee satisfaction. Many of our clients report a significant improvement in indoor climate after replacing old air conditioners.

3. Simplified maintenance : Thanks to the compressor's reliability and reduced number of moving parts, maintenance requirements remain reasonable. However, AirGreen offers comprehensive HVAC maintenance to prevent any risks and extend the life of the system.

4. Design flexibility : VRF takes up less space than bulky ducted systems. It is equally suitable for new construction and renovations requiring mechanical room upgrades.

5. Centralized or local control : The Lennox Cold Climate VRF Varix Extreme is compatible with Mode Selection Boxes (MSBs) that can switch between heating and cooling in different zones simultaneously. This flexibility is particularly useful in buildings where needs vary depending on the time of day or type of activity.

Zoom in on the mode selection box and the indoor units

One of the pillars of the Varix Extreme system's flexibility is the Mode Selection Box . This component manages the direction of refrigerant flow to allow heating in some areas and cooling in others, completely independently. Our teams often find that, in a large building, the air conditioning requirements are not uniform: a technical room may generate a lot of heat, while an adjacent conference room requires additional heating. The box allows for precise control, without wasting energy.

Indoor units available in cassette, wall-mounted, ducted, or ceiling-mounted form factor offer the flexibility to adapt to the architectural configuration of each space. At AirGreen, we systematically analyze room layout and partition placement to select the most efficient type of indoor unit. In a Longueuil hotel, we opted for 4-way cassettes that blend seamlessly into the false ceiling of the corridors, while providing uniform ventilation.

Case study: a commercial building on the North Shore

We recently installed a Lennox Cold Climate VRF Varix Extreme | 24 Tons | Parts by Samsung in a commercial building that combined office and retail space. Located on the North Shore , this three-story building presented several challenges:

• Flexible hours : Ground-floor shops opened early, while administrative offices operated a standard 9-5 schedule.

• Uneven occupancy : Some meeting rooms were only used occasionally, causing excessive energy consumption when a conventional central system was running continuously.

• Extreme weather conditions : Very cold winters and sometimes scorching summers.

By integrating VRF and a mode selection box, building managers were able to reduce their energy bills by approximately 25% over a full year. The ability to heat specific areas while cooling others was particularly appealing to tenants: greater comfort and fewer unpleasant drafts. AirGreen handles regular HVAC maintenance , ensuring system longevity and consistent performance.

Sound quality and easy installation

In addition to saving energy, a VRF system stands out for its reduced sound pressure level . The Lennox Cold Climate VRF Varix Extreme has an outdoor unit output of approximately 62.6 dB(A), which remains discreet for residents and occupants. In server or training rooms, noise pollution is a crucial criterion. The installation of thinner ducts and the absence of large traditional fans further reduce perceived noise.

Our installation teams also emphasize the outdoor unit's ease of handling, thanks to its modular design. Although the capacity is substantial (24 tons), the weight distribution and access to the mounting points allow for easier transport. On some rooftops in downtown Montreal, it's essential to limit space usage and the complexity of lifting when installing the equipment.

Ecological aspects and available subsidies

Going green is a priority for many property managers. The Lennox Cold Climate VRF Varix Extreme is positioned as an energy-efficient solution, Energy Star® certified and using R-410A refrigerant, which already meets stringent environmental standards. Additionally, many property owners are turning to federal and provincial grants to encourage projects that reduce energy consumption and greenhouse gas emissions.

We always recommend that our clients check the financial assistance or grant programs available, as the criteria change regularly. On the South Shore , for example, some programs encourage the use of heat pumps to limit the use of fossil fuels. Our advisors are responsible for guiding clients toward the best options based on their territory and type of project.
