A suspended HVAC solution designed for large volumes in Quebec

At AirGreen , we have been installing HVAC systems for over 15 years in a wide variety of environments: open-ceiling retail spaces in Montreal , professional offices in Laval , institutional spaces in Longueuil , multi-unit residential buildings on the South Shore , and technical facilities on the North Shore . The FUJITSU Centauri ceiling-mounted heat pump with a capacity of 36,000 BTU is ideal precisely in these contexts where a traditional wall unit is not optimal and a central solution would be disproportionate.

This suspended model responds to a well-known field reality: the need for high power , homogeneous air diffusion , reliability in heating at very low temperatures and clean integration into spaces occupied daily.


Designed for the Quebec climate, without compromising on comfort

Stable heating down to -21°C

The FUJITSU Centauri 36,000 BTU is certified to provide heating down to -21°C without shutting down. In practice, this means that in several installations completed by AirGreen—including daycare centers and commercial offices on the South Shore—the system remains active even during prolonged cold spells, without the need for immediate backup heating.

The actual power output observed in winter conditions is a key point:

  • 25,400 BTU at -8°C

  • 31,000 BTU at -15°C

These values ​​make it possible to maintain a stable indoor temperature in open spaces, which are often more difficult to heat than a compartmentalized residential space.

Efficient air conditioning for large areas

In air conditioning, the nominal capacity of 36,000 BTU combined with a high airflow (up to 1,089 CFM) ensures rapid and uniform cooling. In AirGreen projects completed in Montreal East and Laval, this configuration helps avoid the recurring hot spots often observed with undersized systems.


Suspended architecture: when the building's configuration dictates the solution

Why choose a ceiling-mounted system?

In many commercial or institutional buildings, walls are either occupied (display cases, shelves, equipment) or unsuitable for installing wall units. Ceiling-mounted systems offer several practical advantages:

  • Longitudinal air diffusion , ideal for rectangular rooms

  • Easy access for HVAC maintenance

  • Subtle visual impact , particularly appreciated in open spaces

At AirGreen, we recommend this type of unit particularly for:

  • clinics and professional practices

  • retail

  • training rooms

  • open-plan offices

  • common areas of multi-unit residential buildings


Energy performance and measurable efficiency

Performance adapted to current standards

The FUJITSU Centauri 36,000 BTU boasts performance ratings that meet current energy efficiency requirements:

  • SEER2: 21.3

  • HSPF2: 10.4

  • COP at -8 °C: 3.94

In a Quebec context where electricity costs are relatively stable but winter consumption is high, these figures translate into real long-term savings , especially in continuous commercial use.

R-32 refrigerant: a technical and environmental choice

The choice of R-32 gas allows for:

  • a significant reduction in global warming potential

  • improved thermal efficiency

  • a smaller quantity of refrigerant per system

This point is becoming increasingly important in institutional and commercial projects subject to environmental criteria or internal carbon footprint reduction policies.


Air control and acoustics: everyday comfort

Precise airflow management

  • Motorized (automatic) vertical shutters to adjust the airflow height

  • Manually adjustable horizontal shutters , allowing for fine adaptation to the room layout

In several AirGreen installations, this mixed setting helps to avoid direct air currents on workstations, a frequent irritant reported by occupants when the diffusion is poorly controlled.

Controlled noise level

With an indoor noise level ranging from 32 to 44 dB(A) , this heat pump remains suitable for environments where quiet is required: offices, meeting rooms, and healthcare facilities. Under normal conditions, its operation quickly becomes imperceptible to occupants.


Connectivity, control and integration into modern buildings

Controls and automation

The FUJITSU Centauri is compatible with:

  • professional wired controllers

  • infrared remote controls

  • Optional Wi-Fi , with remote monitoring

  • BACnet and Modbus protocols for integration with building management systems

For AirGreen, this aspect is crucial in commercial projects in Montreal and Laval where centralized HVAC management is becoming a standard, particularly in multi-occupancy buildings.


HVAC installation: the AirGreen approach

What we do systematically

Each FUJITSU ceiling-mounted heat pump installation follows a rigorous methodology:

  • actual thermal analysis of the room

  • validation of the suspension structure

  • Precise calculation of pipe lengths (up to 50 m possible)

  • Optimization of drainage and clearances

  • complete commissioning and performance verification

We have learned, through several projects on the North Shore , that poor positioning or an underestimation of the required flow rate quickly leads to complaints about comfort. These errors are avoided thanks to our field experience.

LogisVert Subsidy

This model is eligible for the LogisVert provincial subsidy , currently valued at $3,048 , which significantly improves the return on investment when the heat pump is installed in an eligible context.
