A ceiling-mounted HVAC solution designed for the architectural and climatic realities of Quebec

In a context where residential, commercial, and multi-unit buildings in Quebec must meet high standards for thermal comfort , energy efficiency , and architectural integration , the choice of HVAC system becomes strategic. The FUJITSU CENTAURI | 18,000 BTU Ceiling Cassette Heat Pump was designed specifically to meet these requirements, offering a discreet, stable, and high-performance solution adapted to the harsh winters and humid summers of Montreal , Laval , Longueuil , the North Shore , and the South Shore .

At AirGreen , we recommend and install this model in projects where aesthetics, temperature consistency, and long-term reliability are paramount. This ceiling cassette is particularly well-suited for situations where wall space is limited, already utilized, or where the building design requires even air distribution without visible components.


A ceiling integration that respects the space and interior design

A compact cassette designed for grid ceilings

The FUJITSU CENTAURI 18,000 BTU is designed for direct integration into standard grid-type suspended ceilings, commonly used in commercial buildings, professional offices, and many modern condos. Once installed, only the grid remains visible, creating a clean and discreet visual continuity.

In several AirGreen projects carried out in Boucherville , Laval and Saint-Lambert , this configuration made it possible to fully preserve the interior layout: no visible wall units, no constraints on the furniture, no impact on the layout of work or living spaces.

Uniform and controlled air distribution

The multidirectional diffusion inherent in ceiling cassettes ensures balanced air distribution throughout the room. This feature is essential in:

  • open spaces,

  • the conference rooms,

  • businesses that receive a continuous customer base,

  • offices with variable occupancy.

Unlike some wall systems that can generate areas of overheating or excessive cooling, the FUJITSU CENTAURI cassette promotes a stable and even temperature, improving perceived comfort and reducing constant adjustments.


Reliable heating performance even in extreme cold

Stable heating down to -21°C

Quebec's climate places high demands on heating systems. The FUJITSU CENTAURI | 18,000 BTU Ceiling Cassette Heat Pump is designed to provide reliable heating performance down to -21°C , which corresponds to the actual conditions encountered during winter in Montreal , Laval , Longueuil , on the North Shore and the South Shore .

In several AirGreen projects carried out in multi-unit residential buildings and mixed-use buildings, this model has made it possible to maintain constant thermal comfort without frequent use of auxiliary heating systems, even during prolonged periods of intense cold.

Appropriate power without oversizing

With a rated output of 18,000 BTU , this cassette unit efficiently meets the needs of medium-sized spaces. It offers an optimal balance between actual capacity, controlled energy consumption, and stable operation, avoiding the frequent cycling associated with oversized systems.


Precise air conditioning for hot and humid summers

During the summer months, the FUJITSU CENTAURI provides stable and consistent air conditioning, even in spaces exposed to direct sunlight or with large windows. In downtown Montreal offices and South Shore retail spaces, AirGreen observed a significant improvement in indoor comfort, with reduced temperature fluctuations and shorter cycling times.

Fine-tuning allows for maintaining a constant temperature while limiting electricity consumption, resulting in a more comfortable experience for occupants and better control of operating costs.


Energy efficiency and long-term cost optimization

Concrete performance indicators

The FUJITSU CENTAURI stands out with its high efficiency ratings for both heating and cooling. The COP at -8°C , combined with the SEER2 , HSPF2 , and EER2 values, reflects sustained energy efficiency throughout the year.

For owners of commercial or multi-residential buildings, these performance levels translate into:

  • more predictable electricity bills,

  • a reduction in annual operating costs,

  • improved long-term profitability of the HVAC system.

LogisVert Subsidy

This model is eligible for the LogisVert provincial subsidy , with an amount of up to $1,728 , depending on the applicable criteria. At AirGreen, we support our clients every step of the way:

  • validation of eligibility,

  • file preparation,

  • coordination of the required technical information.

This support applies to both residential projects and installations carried out in Laval , Longueuil , on the North Shore or the South Shore .


Modern technology focused on sustainability

R-32 refrigerant

The FUJITSU CENTAURI uses R-32 refrigerant , known for its reduced environmental impact compared to older gases. This technological choice contributes to better thermal efficiency while reflecting a more responsible approach to heating and air conditioning .

In several recent projects conducted by AirGreen, this criterion has become a determining factor for property managers and companies concerned about the environmental performance of their HVAC systems.

Inverter technology

Thanks to inverter technology, the compressor continuously adjusts its power according to the actual needs of the space. This precise modulation allows:

  • a more stable indoor temperature

  • a reduction in sudden starts,

  • a reduction in mechanical wear,

  • increased system longevity.


Acoustic comfort and indoor air quality

Discreet operation

The FUJITSU CENTAURI cassette is known for its quiet operation, making it particularly suitable for noise-sensitive environments:

  • offices closed

  • meeting rooms,

  • clinics,

  • residential spaces.

In an AirGreen project carried out in an office building in Laval , the replacement of an old noisy system with this cassette eliminated complaints related to ambient noise, significantly improving the comfort of the occupants.

Controlled dehumidification

The integrated dehumidification capability helps maintain pleasant indoor air quality during hot and humid periods, which are particularly common in the Montreal area.


HVAC installation: a key performance factor

A rigorous analysis before installation

Installing a ceiling cassette heat pump requires precise planning: access to the plenum, drainage management, electrical integration, piping sizing, and compliance with applicable standards.

At AirGreen , each project begins with a complete analysis of the building to ensure a sustainable, efficient installation perfectly adapted to the existing configuration.

Concrete examples of AirGreen installations

  • Condo in Montreal : replacement of a noisy central system with a FUJITSU CENTAURI cassette, without modification of the interior layout.

  • Office in Longueuil : installation of a discreet HVAC system for a glass-walled meeting room requiring uniform and quiet air distribution.

  • Commerce on the South Shore : planned intervention allowing activities to continue without prolonged interruption.

These examples illustrate the importance of entrusting the installation to a team specializing in HVAC installation who understands local realities.


Guarantee and peace of mind

The FUJITSU CENTAURI Ceiling Cassette Heat Pump | 18,000 BTU comes with a 12-year warranty on the compressor and parts . AirGreen also offers additional warranty options to provide complete protection and long-term peace of mind.
