FUJITSU AIRSTAGE J-7S Mini-VRF R32 | 36000 BTU - 9 Heads

A Mini-VRF architecture designed for the complex realities of Quebec buildings

In many of the projects we undertake at AirGreen , one observation keeps recurring: today's buildings—whether they be plexes in Montreal , multi-unit dwellings in Laval , new condos on the South Shore , or hybrid offices on the North Shore —demand HVAC systems that are far more flexible than in the past. Uses are diverse, heat loads vary significantly from one area to another, and expectations for comfort and energy efficiency are high.

The FUJITSU AIRSTAGE J-7S Mini-VRF R32 – 36,000 BTU , capable of powering up to 9 indoor units , was specifically designed to meet these requirements. It is aimed at homeowners and managers looking for a centralized solution, but without the complexity of a traditional commercial VRF system.

At AirGreen , we position this system as a technical solution when traditional multi-zone heat pumps reach their limits: too many zones, too much distance between the outdoor unit and the spaces served, or a need for very precise room-by-room control.

A compact Mini-VRF design, conceived for the urban environment

One of the major advantages of the AIRSTAGE J-7S lies in its compact exterior format . In dense urban environments, particularly in Montreal and Longueuil , the space available for outdoor units is often limited: narrow balconies, shared backyards, and already cluttered technical roofs.

Thanks to its reduced footprint and lighter weight compared to previous generations, this unit can be installed in locations that were previously difficult or even impossible to access, without compromising performance. In several projects completed by AirGreen, this has allowed the building's aesthetics to be preserved while complying with municipal regulations and condominium constraints.

Up to 9 independent zones on a single outdoor unit

With a rated capacity of 36,000 BTU , the J-7S can power up to 9 indoor units , each capable of operating independently. This zone independence is a major advantage in mixed-use buildings or in homes with high occupancy rates.

Compatible indoor units offer a rare degree of design freedom:

• Slim ducted units , ideal for discreet integration into ceilings

• Compact cassettes , suitable for standard ceiling grids

• Wall-mounted units , for targeted areas or confined spaces

• Multi-position air handling units , perfect for integration into an existing ductwork network

In practice, we often combine several types of units on the same system: for example, ducted units for common areas and wall-mounted units for closed offices or housing.

Heating performance adapted to harsh winters

In Quebec, actual heating capacity in cold weather is a key factor. The FUJITSU AIRSTAGE J-7S is designed to operate in heating mode down to -26°C without premature shutdown. This feature is essential during the prolonged cold spells we regularly experience in Laval , Terrebonne , and Boucherville .

In practical terms, this translates to:

• continuous heating , even on the coldest nights

• a reduction in the use of supplementary electrical systems

• a more stable comfort for the occupants

In several replacements of existing electrical systems carried out by AirGreen, the switch to a Mini-VRF J-7S improved thermal consistency while reducing overall energy consumption.

Energy efficiency and optimization of operating costs

The AIRSTAGE J-7S is not just about providing power. It is also designed to operate with high seasonal efficiency , which is particularly important in buildings where multiple zones are active simultaneously, but at different loads.

In a real-world operational context, this means:

• improved power modulation according to actual demand

• Fewer short cycles, therefore reduced wear

• more predictable consumption over the year

For property managers, this stability is a major advantage, particularly in rental buildings where energy costs have a direct impact on profitability.

R-32 refrigerant: a coherent technical choice

The choice of R-32 is not insignificant. This new generation refrigerant allows for better thermal performance while reducing environmental impact compared to older fluids.

In the projects we undertake, this offers several concrete benefits:

• a lower refrigerant charge

• improved heating and air conditioning efficiency

• increased compliance with current and future environmental standards

For medium and large buildings, this also facilitates security management, particularly through the possible integration of detection devices on certain configurations.

A crucial installation flexibility for complex construction sites

Extended pipe lengths

The Mini-VRF J-7S allows for large piping lengths , which opens the door to complex configurations: remote outdoor units, service to multiple floors, or bypassing structural elements.

In older buildings in Montreal , where routes are never perfectly linear, this flexibility is often what makes the project technically viable.

Static pressure and controlled air distribution

Some compatible indoor units offer increased static pressure , enabling efficient air distribution even with longer or more complex ductwork. For AirGreen, this means fewer design compromises and improved overall occupant comfort.

System control, management and scalability

The FUJITSU AIRSTAGE J-7S can be equipped with various control solutions:

• local wall-mounted controls

• individual remote controls

• central controllers for overall management

• interfaces enabling remote monitoring

In commercial or multi-residential buildings, this centralized management facilitates maintenance, performance monitoring and adaptation of the system to changing uses.

Concrete feedback from our AirGreen installations

In several recent projects on the South Shore , we installed J-7S Mini-VRFs in buildings combining retail space on the ground floor and apartments on the upper floors. The result: a single outdoor unit, precise zone control, and a significant improvement in comfort for the occupants.

We particularly recommend this system when:

• the number of zones is high

• thermal loads are highly variable

• outdoor space is limited

• The client wants a sustainable and scalable solution.

Long-term guarantee and peace of mind

The system benefits from an extended warranty on the compressor and parts , with the option of additional coverage. For our customers, this represents significant peace of mind: fewer unexpected problems, better planning of HVAC maintenance costs, and long-term added value for the building.

Why entrust your Mini-VRF project to AirGreen

A Mini-VRF system requires genuine expertise : zone design, precise load calculations, refrigerant management, and rigorous commissioning. At AirGreen , our certified refrigeration technicians are experts in these advanced systems and work daily in Montreal , Laval , Longueuil , and on the North and South Shores .

We prioritize clear quotes, careful installation and post-commissioning support, so that every HVAC project is a reliable and sustainable investment.
