A ceiling cassette designed for projects where comfort allows for no compromise

In the HVAC sector in Quebec , certain building configurations require significantly more sophisticated solutions than a simple conventional wall-mounted or central unit. Open spaces, suspended ceilings, acoustic constraints, extended operating hours, and especially the need for stable heating in the depths of winter necessitate precise technical choices. The FUJITSU CENTAURI 18,000 BTU wide-ceiling cassette heat pump perfectly meets these needs.

At AirGreen , we have integrated this model into numerous projects in Montreal , Laval , Longueuil , on the North Shore and the South Shore , in high-end residential, commercial , and multi-unit settings. Over time, this cassette has established itself as a coherent solution when performance must go hand in hand with discretion and consistency.


An air distribution system designed for the actual comfort of the occupants

Why the ceiling cassette changes the thermal experience

Unlike wall units, which project air in a dominant direction, the FUJITSU CENTAURI ceiling cassette diffuses air evenly along multiple axes . This feature is crucial in spaces where:

  • The surface is open or irregular

  • The occupants are spread over a large area

  • Temperature variations are particularly noticeable.

In several offices and shops where AirGreen has worked, clients previously reported significant temperature differences between different areas of the same room. The ceiling cassette has stabilized the ambient temperature without creating direct drafts or uncomfortable zones.

A clean and discreet architectural integration

The FUJITSU CENTAURI is designed to integrate seamlessly into standard suspended ceilings. Once installed, only the grid is visible, thus preserving:

  • Interior aesthetics

  • The flexibility of layout

  • The perceived value of space

In modern condominium projects in Laval and Brossard , this discretion was a decisive criterion, particularly in units where the walls did not allow the installation of visible equipment.


Heating in cold climates: a non-negotiable point in Quebec

Actual performance down to -21°C

The FUJITSU CENTAURI 18,000 BTU heat pump is designed to provide reliable heating down to -21°C , a threshold that corresponds to typical Quebec winter conditions. In practical terms, this means:

  • Heating capacity maintained even during periods of intense cold

  • Stable operation without repeated stops

  • A reduction in the use of backup systems

In commercial buildings in Montreal , where heating must remain constant for operational reasons, this stability has proven essential. We have found that, when properly installed and correctly sized, this cassette delivers consistent performance even when external conditions become demanding.

Understanding useful power, not just the nominal figure

Although the rated power is 18,000 BTU , it's important to consider the actual low-temperature capacity . At -8°C , this unit continues to deliver significant power, allowing it to cover a large portion of the heating needs without a sudden drop in performance.

At AirGreen , we always emphasize this distinction when analyzing a project, because this is precisely where the difference lies between a heat pump that performs well on paper and a system that is truly comfortable in winter.


Energy efficiency and long-term effectiveness

Indices adapted to northern climates

The FUJITSU CENTAURI stands out with energy performance designed for year-round use:

  • High SEER2 , ensuring efficient air conditioning during the summer months

  • Optimized HSPF2 , essential for heating over a long season

  • High COP at -8°C , a key indicator of actual heating efficiency

For building owners and managers, these elements translate into controlled electricity consumption , which is particularly valuable in continuously occupied buildings.

The choice of R-32 refrigerant

The use of R-32 gas is part of a modern and responsible approach:

  • Better heat transfer

  • Reduced refrigerant charge

  • Lower environmental impact compared to previous generations

In several projects eligible for energy support programs, this choice facilitated compliance with the required criteria, while offering stable performance.


Key technical specifications of the FUJITSU CENTAURI 18,000 BTU

  • Rated capacity : 18,000 BTU

  • Cooling capacity : 18,000 BTU

  • Heating function down to : -21 °C

  • Usable output at -8°C : approximately 14,400 BTU

  • Refrigerant : R-32

  • Power supply : 220 V

  • Indoor noise level : very low, suitable for sensitive environments

  • Warranty : 12 years compressor, 12 years parts, 0 years labor (extensions available)

These characteristics make this cassette a balanced solution, capable of meeting high technical requirements without unnecessary complexity.


Installation: the importance of field expertise

A ceiling cassette should never be installed lightly.

Installing a ceiling cassette heat pump involves much more than simply connecting the unit. Each project requires:

  • An analysis of the ceiling structure

  • Rigorous management of condensation drainage

  • Precise positioning to optimize air diffusion

  • Coordination with the electrical department and, sometimes, other trades

At AirGreen , we've learned to anticipate common mistakes: insufficient drainage slope, limited access for maintenance, and poor airflow distribution. These details, often invisible at first, nevertheless determine the system's reliability over many years.

Concrete feedback from completed projects

  • Montreal : professional offices where the priority was acoustic comfort and thermal stability over long periods of time

  • Laval : Multi-unit residential buildings requiring a discreet solution without compromising on winter heating

  • South Shore : commercial premises where uniform air distribution directly improved the customer experience

In each of these contexts, the FUJITSU CENTAURI was able to meet specific constraints, provided that it was installed rigorously.


Modern HVAC control, connectivity and management

This heat pump offers considerable control flexibility , particularly in professional environments:

  • Wired or wireless controllers

  • Wi-Fi option for remote control

  • Compatible with BACnet and Modbus

  • Possible integration with building management systems

In some commercial projects monitored by AirGreen , this compatibility has made it possible to centralize comfort management, reduce manual adjustments and simplify long-term maintenance.


What types of projects is the FUJITSU CENTAURI really intended for?

This ceiling cassette is primarily intended for:

  • Professional offices

  • Modern condos with suspended ceilings

  • Shops and open spaces

  • Clinics, meeting rooms, service facilities

  • Buildings seeking a high-performance and discreet solution

It is not designed to replace all possible configurations. That is why a preliminary analysis remains essential to ensure consistent and sustainable sizing.


LogisVert subsidy and overall financial value

The FUJITSU CENTAURI 18,000 BTU is eligible for the LogisVert provincial grant , with an amount of up to $1,728 , subject to applicable conditions. Beyond financial support, this program promotes the adoption of truly efficient systems in Quebec's climate.

At AirGreen , we support our clients at every stage to maximize their chances of eligibility and avoid common administrative errors.


Why entrust this type of project to AirGreen?

The performance of a cassette heat pump depends as much on the product itself as on how it is integrated into the building. By choosing AirGreen , you benefit from:

  • From concrete experience on complex projects

  • Qualified technicians experienced in ceiling installations
