A Mini-VRF design truly adapted to the demanding buildings of Quebec.

At AirGreen , we see every day that buildings in Montreal , Laval , Longueuil , the North Shore , and the South Shore rarely present ideal conditions for standard HVAC systems. Irregular volumes, multiple floors, mixed uses, successive renovations, and restrictions on exterior installation: these realities demand a more advanced approach than a simple conventional multi-zone system.

The FUJITSU AIRSTAGE J-7S Mini-VRF 24,000 BTU – 5 zones R32 fits perfectly into this framework. It is a next-generation HVAC platform, designed to offer precise thermal management , exceptional stability in winter heating , and superior installation flexibility , all while remaining compact and energy-efficient.

Unlike traditional multi-zone solutions, the J-7S Mini-VRF allows for much more precise modulation of the power sent to each indoor unit. This results in consistent comfort, fewer unnecessary cycles, and increased lifespan for mechanical components.

A solution designed for modern urban and residential constraints

In central Montreal or densely populated areas of Laval , space for outdoor units is often limited. The J-7S stands out with its small footprint , low height , and compact design , allowing for easy installation.

• under a window,

• on a balcony,

• along a shared wall,

• in a narrow backyard.

This flexibility is crucial to complying with municipal regulations, condominium constraints and aesthetic requirements, without compromising system performance.

Heating and cooling performance under real-world conditions

Stable heating down to -26°C, without loss of control

In Quebec, an HVAC system is judged on its ability to maintain comfort during prolonged periods of intense cold. The FUJITSU AIRSTAGE J-7S was designed to ensure reliable operation down to -26°C , without unexpected shutdowns or sudden drops in performance.

In concrete terms, this is based on:

• a basic heating system integrated into the outdoor unit,

• advanced defrosting management,

• electronic components protected and cooled by the refrigerant,

• a control logic designed for cold climates.

In several installations carried out by AirGreen on the North Shore and in Montérégie , occupants notice a stable indoor temperature even during the coldest nights, without oscillations or excessive noise.

Detailed thermal capacities – 24,000 BTU model

• Cooling capacity : 24,000 BTU

• Rated power : 24,000 BTU

• Available power at -8°C : 17,400 BTU

• Available power at -15°C : 26,200 BTU

• COP at -8 °C : 12.443

• ENERGY STAR® Certification : Standard and Cold Climate

• AHRI Number : 216372779

These values ​​reflect remarkable energy efficiency, particularly advantageous for homeowners keen to reduce their electricity consumption while maintaining a high level of comfort.

Subsidies and long-term profitability

Eligibility for the LogisVert provincial subsidy

The FUJITSU AIRSTAGE J-7S 24,000 BTU is eligible for a $2,088 LogisVert grant , subject to applicable criteria. At AirGreen , we systematically integrate this aspect from the planning phase in order to:

• confirm eligibility before installation,

• optimize the system sizing,

• provide the documents required for the grant application.

This approach avoids late rejections and allows for a realistic financial projection from the outset.

Advanced multi-zone control: targeted comfort and real savings

Up to 5 independent zones, without compromise

The core of the J-7S Mini-VRF lies in its ability to manage up to 5 separate zones , each with its own temperature control. This configuration is ideal for:

• multi-story houses,

• intergenerational housing,

• professional offices,

• Shops with areas of varying occupancy

• small multi-unit apartment buildings.

Each zone receives only the necessary power, which reduces energy waste and improves perceived comfort.

Extended compatibility of indoor units

The system is compatible with several types of indoor units, allowing for precise adaptation to each space:

• Slim ducted unit : ideal for discreet distribution via ducts

• Compact cassette : perfect for suspended ceilings or commercial spaces

• Wall mounting : a simple and effective solution for individual rooms

• Multi-position air handling unit : can be integrated into existing ductwork.

This versatility allows different technologies to be combined in the same building, without unbalancing the overall system.

HVAC installation: flexibility, precision and safety

Extended pipe lengths for complex buildings

The J-7S allows for a total piping length of up to 120 m , which greatly facilitates installation in:

• multi-story buildings,

• narrow buildings,

• buildings with an outdoor unit located away from the spaces served.

In several projects carried out in Longueuil , this feature has made it possible to avoid costly structural work or aesthetic compromises.

R-32 refrigerant: integrated efficiency and safety

The choice of R-32 allows for:

• a reduction in environmental impact,

• improved energy efficiency

• a reduced refrigerant charge.

The system also incorporates advanced security features, such as:

• leak detection sensors on certain indoor units,

• Optional audible and visual alarms,

• possibility of automatic refrigerant shut-off valve.

These features are particularly appreciated in multi-unit residential buildings and commercial environments.

HVAC Maintenance and Operational Durability

A properly installed Mini-VRF system also needs to be well maintained to retain its performance. During our HVAC maintenance services, we pay particular attention to:

• the condition of the heat exchangers,

• pressure stability,

• the operation of safety sensors,

• the cleanliness of the indoor units,

• condensate drainage management.

The FUJITSU AIRSTAGE J-7S was designed to facilitate these interventions, reducing downtime and extending system life.

Why entrust your Mini-VRF project to AirGreen

High-performance equipment only delivers optimal results if it is correctly sized and installed . At AirGreen , we offer:

• HVAC expertise specific to Quebec realities,

• experienced and certified refrigeration technicians,

• detailed and transparent quotes before work begins,

• $5,000,000 liability insurance

• comprehensive support before, during and after installation.

We operate daily in Montreal , Laval , Longueuil , on the North Shore , the South Shore and in Montérégie , with a deep understanding of local standards and constraints specific to each type of building.

Common mistakes to avoid with a Mini-VRF

Over the years, we have identified several common mistakes:

• undersize the system to reduce the initial cost,

• poorly distributing thermal loads by zone,

• neglecting permissible pipe lengths,

• install without providing access for future maintenance.

A rigorous design from the outset helps to avoid these problems and ensures stable performance over the long term.
