A complete VRF system for optimized commercial HVAC installations

At AirGreen, we have been supporting property owners and managers in Montreal , Laval , Longueuil , the North Shore and the South Shore for years with their HVAC installation and HVAC maintenance projects. In many commercial and multi-residential buildings, the priority is to achieve optimal comfort, controlled energy costs and layout flexibility. The LENNOX Varix VRF MultiZone | 6 Tons 575V | Parts by Samsung meets these needs precisely. Its VRF (Variable Refrigerant Flow) approach and its technology combining Lennox know-how with parts developed by Samsung make it a must-have for demanding air conditioning and heating projects.

A strategic choice to better manage up to 12 zones

One of the main advantages of this LENNOX Varix VRF MultiZone | 6 Tons 575V is its ability to manage up to 12 different zones in a single building. Each zone can receive the required amount of heating or cooling independently. This means a considerable improvement in temperature control for spaces with various uses:

• Office floors with uneven thermal loads

• Businesses whose needs fluctuate according to traffic

• Common areas (entrance halls, corridors, waiting rooms) with different comfort requirements

This multi-zone functionality is achieved through the VRF principle, which modulates the amount of refrigerant (R-410A) distributed to each indoor unit. Unlike older oversized or centralized systems, VRF avoids energy losses and ensures adjustment as close as possible to actual needs.

Technical characteristics and concrete advantages

The LENNOX Varix VRF MultiZone | 6 Tons 575V offers a cooling capacity of around 72,000 BTU and the ability to heat down to -30°C . Our teams at AirGreen have been able to verify on several construction sites that this operating range is perfectly suited to the Quebec climate, even during the intense cold of January.

We know that HVAC installation can be challenging in commercial buildings. However, the modularity of this system makes it easier to install refrigerant ducts and limits the need for large air distribution ducts. The liquid, suction, and hot gas tubes take up less space than traditional centralized ventilation, helping to preserve interior space for other uses.

Here are some details:

• Voltage : 575V, suitable for Canadian industrial and commercial environments.

• Noise level (outdoor unit): approximately 58 dB(A) , a point particularly appreciated for buildings near residential areas.

• Refrigerant gas : R-410A , frequently used and easy to supply on the Quebec market.

• Warranty : 10 years on the compressor, 10 years on parts (regularly called 10-10-0 warranty). An extension of up to 10 years of labor (10-10-10) is also available for complete peace of mind.

Field experience: customer feedback and commissioning

Our AirGreen experts have already installed this LENNOX Varix VRF MultiZone in several properties in Montreal and Laval :

1. Large office complex : Management wanted individual temperature control for each department to reduce comfort conflicts between employees. With this VRF, we were able to organize up to 10 separate zones. Feedback highlighted a decrease in temperature-related complaints and a significant drop in energy bills.

2. South Shore Medical Center : Examination rooms require a cool temperature, while waiting areas prefer a more temperate level. The LENNOX Varix VRF MultiZone helped maintain a stable environment, even during peak heatwaves. The reduced noise from the outdoor unit was also a benefit for patients.

3. Boutique hotel in Longueuil : Thanks to VRF, management can independently control each floor based on occupancy. Energy savings of more than 20% have been observed.

VRF accuracy: operation and regulation

The VRF 's success lies in its ability to continuously adjust the amount of refrigerant required. The digital inverter compressor controls the operating power to modulate the demand of each zone. In practice, this means that if only two floors are occupied, the system doesn't need to run at full capacity. This avoids uncomfortable temperature fluctuations and wasted energy.

Key advantages of this technology include:

• Reduced operating costs : By modulating the power from 100% to a lower percentage, unnecessary electricity consumption is limited.

• Extended component life : Fewer sudden starts/stops, therefore less wear on the compressor.

• Acoustic comfort : More linear operation reduces sound peaks.

Parts by Samsung: reliability and technical support

Lennox partnered with Samsung to develop a high-performance system, supported by a global network of reliable spare parts. For our projects in Montreal and the suburbs, this means quick access to replacement parts when needed. Combined with the 10-year (or even 10-10-10) warranty, this availability enhances homeowners' peace of mind.

HVAC maintenance and after-sales service: AirGreen expertise

Although VRF technology is robust, regular HVAC maintenance remains crucial to ensure optimal operation. At AirGreen, we offer:

• Seasonal Inspections : Checking refrigerant pressure, cleaning indoor and outdoor units, checking sensors and valves.

• Preventive maintenance : Removal of deposits and dirt in the exchangers to maintain a high level of performance.

• 24/7 Service : In the event of a breakdown, we quickly dispatch our technicians trained in Lennox and Samsung systems.

Thanks to these measures, many of our clients (large chain stores, condominiums, etc.) maintain a high satisfaction rate and avoid costly interruptions.

The strategic role of sizing and design

To fully benefit from a VRF system like the LENNOX Varix VRF MultiZone | 6 Tons 575V , it is essential to correctly size the power and distribution of the indoor units. We have seen cases where an incorrect heat load calculation caused overconsumption or a lack of comfort in certain areas. Our engineers and technicians ensure:

• Precisely analyze internal losses and contributions (electrical devices, human occupation).

• Check electrical wiring constraints (575 V) and space available for refrigerant lines.

• Coordinate the installation of mode selection boxes (MSB) that distribute hot or cold refrigerant to each unit.

Common Mistakes to Avoid

1. Neglecting staff training : It is essential that building operators or managers understand the basic principles of VRF operation to make the correct seasonal adjustments.

2. Postpone maintenance : Cleaning filters too frequently or not checking refrigerant connections enough can lead to performance leaks.

3. Underestimating future expansion needs : If the number of zones increases (expansion, renovation), it is better to allow for a margin when selecting the VRF unit.

4. Installing the outdoor unit in a confined space : Although relatively compact, the outdoor unit needs good air circulation.

Why this choice is suited to the Quebec climate

With a heating capacity down to -30°C , the LENNOX Varix VRF MultiZone handles extreme temperatures common in the greater Montreal area. Its flash injection compressor (featured on the Varix range) and optimized defrost cycles allow for high performance levels to be maintained, even in extremely cold weather. Many building managers have noted a reduction in their use of backup systems.

And for the summer season?

The same logic applies to cooling, with a range that can extend to scorching temperatures. In Longueuil or on the North Shore , this system easily withstands periods of persistent heat. Customers who own server rooms, for example, appreciate that the VRF responds very quickly to internal heat spikes.

Concrete achievements in Quebec

• Administrative building in Montreal : Installation of a multifunctional VRF network on five floors. The result: uniform comfort and approximately 15% reduction in energy bills.

• Logistics company in Laval : The office and warehouse areas had different needs. The VRF precisely manages air conditioning in the offices and the minimum heating required in the storage areas.

• Sports Center on the South Shore : Integration of temperature management in the changing rooms, the indoor pool (linked to dehumidification) and the stands.
