A Mini-VRF system designed for Quebec buildings, not for brochures.

At AirGreen Heat Pumps, Air Conditioning & Heating , we install HVAC systems in real buildings, occupied by real people, subject to real constraints: long winters, persistent cold, humid summers, limited mechanical space, strict municipal regulations, and high expectations for comfort. The FUJITSU AIRSTAGE J-7S Mini-VRF R32 36,000 BTU unit with two heads fits perfectly into this reality.

This system wasn't designed to impress on a spec sheet, but to operate stably and predictably in complex environments: Montreal duplexes, renovated triplexes, multigenerational homes, small multi-unit buildings, or hybrid residential-office buildings. It is precisely in these projects that we see, year after year, that the J-7S Mini-VRF makes a real difference.

Understanding the benefits of Mini-VRF in a dense urban environment

A more refined HVAC logic than traditional multi-split systems

In numerous projects in Montreal, Laval, and Longueuil , we are called upon to replace poorly designed multi-split systems: cycles that are too short, temperature differences between zones, and chronic discomfort at certain times of day. The Mini-VRF J-7S operates on a different principle. Modulating the refrigerant flow allows each indoor unit to receive exactly what it needs , no more and no less.

In practical terms, this means that two zones powered by the same system can operate completely independently, without interfering with each other. A north-facing room can be heated efficiently while a sunny south-facing space automatically limits its heating demand. This level of control is particularly valuable in multi-story buildings, which are very common on the North Shore and in several central areas of Montreal.

A thermal stability that can be felt on a daily basis

In our field experience, the main benefit perceived by occupants is not just maximum performance, but stability . The J-7S maintains a constant temperature, without sudden fluctuations or excessive airflow. This stability improves comfort, reduces perceived noise, and decreases wear on mechanical components, which has a direct impact on the system's longevity.

Heating performance: meeting the real challenges of Quebec winters

Reliable heating down to -26°C

The FUJITSU AIRSTAGE J-7S is designed to provide continuous heating down to -26°C , without unnecessary safety shutdowns. In several installations completed by AirGreen in Laval and on the South Shore , this feature proved crucial during periods of prolonged cold, when other systems quickly lost efficiency.

With a rated output of 36,000 BTU , the system maintains a very high usable capacity at low temperatures, significantly reducing reliance on supplementary electric heating systems. For homeowners, this translates into more predictable energy consumption and better control over energy costs.

Energy efficiency adapted to subsidies

The J-7S is ENERGY STAR® certified, including the cold climate designation, making it eligible for financial assistance programs like LogisVert . At AirGreen, we always incorporate these elements from the initial submission phase so our clients have a clear understanding of the project's true cost after subsidies.

In several recent cases in Longueuil and Boucherville , this approach has made it possible to make a Mini-VRF solution economically viable where it initially seemed out of budget.

Efficient air conditioning and humidity control in summer

A stable cooling capacity at high heat

With a cooling capacity of 36,000 BTU , the J-7S provides reliable air conditioning even during the intense heat and humidity that Greater Montreal regularly experiences. The system is designed to operate at high ambient temperatures without loss of stability, a crucial feature for buildings with extensive glazing or south-facing exposure.

Summer comfort without excessive drafts

Thanks to precise modulation and numerous indoor unit options, it's possible to prioritize a gentle and even distribution of air. In projects completed by AirGreen in renovated homes in Villeray and Rosemont , this type of configuration eliminated complaints related to cold drafts while maintaining excellent humidity control.

Installation flexibility is crucial for complex projects.

Compatible with several types of indoor units

The FUJITSU AIRSTAGE J-7S Mini-VRF accepts a wide range of indoor units, allowing the system to be adapted to the architectural reality of the building:

• Slim ducted units for invisible integration into ceilings

• Compact cassettes ideal for open spaces

• Wall-mounted units for targeted renovations

• Multi-position air handling units for specific distribution needs

In a recent project in Ahuntsic , we combined a ducted unit for common areas and a wall-mounted unit for a home office. This hybrid approach optimized comfort without increasing the number of external units.

Pipe length and urban constraints

The maximum piping length offered by the J-7S opens up possibilities where other systems quickly reach their limits. In dense urban environments, this flexibility is essential for working around stairwells, load-bearing walls, or narrow backyards, which are very common in Montreal .

The outdoor unit, more compact than previous generations, can be installed under a window or on a balcony, provided that clearance requirements are met. In several projects on the South Shore , this feature has made it possible to avoid costly modifications to the building envelope.

R-32 refrigerant: a coherent and sustainable technical choice

Using R-32 reduces the total refrigerant charge while improving thermal efficiency. In practice, this translates to better system responsiveness and greater compliance with current and future environmental standards. For homeowners planning for the long term, this is a significant advantage.

At AirGreen, we also pay particular attention to refrigerant-related safety devices, especially in ducted systems. These elements are an integral part of our standard practices, even when they are not a minimum requirement of the code.

Key points we monitor during each installation

Precise sizing and balancing of areas

An improperly sized Mini-VRF quickly loses its advantages. Every project begins with a detailed analysis of the thermal loads : insulation, orientation, surface area, and actual room usage. This step ensures balanced operation of both zones without overworking the compressor.

Acoustic management and harmonious integration

Even with an outdoor noise level of approximately 57 dB(A) , positioning remains crucial. We systematically use anti-vibration mounts and pay particular attention to the orientation of the outdoor unit, especially in dense residential areas.

Maintenance and durability

A well-installed system is an easier system to maintain. The J-7S offers clear mechanical access and an architecture that facilitates future interventions. For our customers in Laval and the North Shore , this means fewer surprises and better-controlled maintenance costs in the long run.

Who is the FUJITSU AIRSTAGE J-7S 36,000 BTU – 2 heads really aimed at?

This system is particularly well-suited to the following projects:

• Duplexes and triplexes in Montreal

• Intergenerational housing

• Small multi-unit apartment buildings

• Residential spaces combined with an office

• Renovations where outdoor space is limited

In these contexts, the Mini-VRF represents a coherent, sustainable and technically sound solution, far superior to several traditional configurations.
