FUJITSU AIRSTAGE J-7S VRF R32 | 48000 BTU - 6 Indoor Units

An HVAC solution designed for demanding buildings in Quebec

In the current real estate market in Montreal , Laval , Longueuil , on the North Shore , the South Shore , and in the Montérégie region , heating, ventilation, and air conditioning (HVAC) requirements have changed dramatically. Buildings are denser, uses more varied, and expectations for thermal comfort are much higher than they were ten years ago. Owners and managers are now looking for systems capable of providing precise zone control , impeccable stability in winter , and measurable energy efficiency , without increasing equipment or maintenance costs.

It is precisely in this type of context that the FUJITSU AIRSTAGE J-7S VRF R32 – 48,000 BTU , configured here with 6 indoor units , truly shines. This next-generation Mini-VRF was designed to meet North American realities, and more specifically the climatic and regulatory constraints of Quebec.

At AirGreen, this system stands out as a strategic solution when traditional multi-zone systems reach their limits, both in terms of performance and installation flexibility.

A Mini-VRF design made for real life

Stable heating down to -26°C, even during prolonged cold spells

One of the most frequent issues we encounter during service calls in the dead of winter is the loss of heating capacity when temperatures drop significantly. The AIRSTAGE J-7S was designed to prevent this scenario.

Thanks to its optimized architecture and components specifically adapted to cold climates, the system ensures reliable operation down to -26°C , without interruption, and with high thermal capacity retention. In practice, this means:

• consistent warmth in all areas, even on very cold nights,

• fewer intrusive defrost cycles,

• a reduction in complaints related to temperature variations between spaces.

In several multi-unit residential buildings in Longueuil and on the North Shore , this level of stability has made it possible to completely eliminate the use of auxiliary heating, which is often costly and energy-intensive.

Energy efficiency that is reflected in the bills

Beyond comfort, energy efficiency remains a key consideration. The FUJITSU AIRSTAGE J-7S VRF R32 boasts some of the highest performance indicators in its class:

• SEER2 is very high for air conditioning.

• HSPF2 optimized for seasonal heating,

• COP of 12.13 at -8 °C , demonstrating excellent conversion of electrical energy into useful heat.

In concrete terms, in buildings occupied year-round — professional offices, clinics, residential buildings — these performances translate into a real reduction in operating costs , particularly during the long heating seasons typical of Quebec.

R-32: a refrigerant adapted to current and future standards

The choice of R-32 is not insignificant. It is a more modern refrigerant, offering:

• a reduced global warming potential ,

• a lower refrigerant charge compared to previous generations,

• improved overall thermodynamic efficiency.

For building owners in Montreal and Montérégie , this represents a long-term advantage, both environmentally and regulatory-wise, in a context where standards are evolving rapidly.

A truly usable multi-zone flexibility

Up to 12 zones can be controlled from a single outdoor unit

The AOUK048SSAN7 model can power up to 12 indoor units , with a standard, balanced 6-zone configuration, as shown here. This capacity opens the door to a wide variety of installation scenarios:

• one apartment per floor with independent monitoring.

• commercial spaces combining offices, meeting rooms and reception areas,

• multi-generational residences where each occupant adjusts their comfort.

Unlike conventional multi-split systems, the Mini-VRF manages loads much more precisely, which avoids performance differences between zones.

A wide selection of indoor units for customized integration

One of the major strengths of the AIRSTAGE J-7S lies in the diversity of compatible indoor units:

• Slim ducted unit , ideal for invisible integration into ceilings or soffits.

• Compact cassette , perfectly suited to standard ceilings in offices and shops,

• Wall-mounted unit , renowned for its quiet operation and simplicity,

• Multi-position air handling unit , used when larger volumes need to be served.

This flexibility allows AirGreen to design coherent HVAC systems, where each space receives the most appropriate solution, rather than forcing a single model on the entire building.

Installation: where AirGreen's expertise makes the difference

A compact outdoor unit, designed for urban environments

In many projects in Montreal , outdoor space is a limiting factor. The FUJITSU AIRSTAGE J-7S stands out with an outdoor unit that is much more compact than those of comparable capacity. It can be installed:

• under a window,

• on a balcony,

• in a narrow backyard

• or in areas where clearances are restricted.

This feature significantly reduces the constraints related to municipal regulations and outdoor planning.

Pipe lengths and elevations adapted to complex buildings

The system allows:

• significant lengths of piping ,

• a very high maximum height difference between the outdoor unit and the indoor units.

This allows the outdoor unit to be installed in a strategic location, even in multi-story buildings, without compromising the overall performance of the system.

Common mistakes we systematically avoid

In poorly planned Mini-VRF installations, we frequently observe:

• poor sizing of the zones,

• an imbalance between heating and air conditioning

• an inadequate selection of interior units according to the actual use of the spaces.

At AirGreen, every project begins with a thorough HVAC analysis , taking into account the building envelope, occupancy patterns, and future constraints. This approach avoids costly fixes and ensures lasting satisfaction.

A system eligible for subsidies and designed for the future

The FUJITSU AIRSTAGE J-7S VRF R32 is eligible for provincial subsidy programs, including LogisVert , with a grant of up to $4,296 , subject to applicable conditions. For many customers in Laval and on the South Shore , this financial assistance has allowed them to recoup their investment more quickly.

Add to that a 12-year warranty on the compressor and parts , and you have an HVAC solution designed for a long-term horizon.

Why choose AirGreen for this type of project?
