A suspended solution designed for the demanding spaces of Quebec

At AirGreen, we have been installing HVAC systems for over 15 years in a wide variety of settings: professional offices, retail stores, clinics, condominiums, and residences with specific architectural constraints. The FUJITSU Centauri 18,000 BTU ceiling-mounted heat pump is one of the solutions we recommend when performance, quiet operation, and reliability in cold climates are non-negotiable.

This model from the AIRSTAGE Centauri series has been designed to offer stable comfort all year round, even when outside temperatures drop to -21°C , a well-known reality in Montreal , Laval , Longueuil , on the North Shore and the South Shore .

Ceiling-mounted design: a tangible advantage in the field

An ideal integration when walls are not an option

In many projects carried out by AirGreen, particularly in renovated shops or professional spaces, traditional wall mounting is simply not suitable. Ceiling-mounted units offer the following advantages:

• A homogeneous distribution of air over large areas

• A complete liberation from the walls , useful in glazed or fitted spaces.

• A more consistent installation in premises with standard or semi-industrial ceilings

We recently installed this model in a shared office in Boucherville , where the main constraint was to preserve the aesthetics of the load-bearing walls while ensuring constant airflow in several work areas. The result: uniform comfort, without direct drafts, and a virtually imperceptible noise level.

Shutters and air diffusion

• Automatic vertical control to continuously adjust the direction of airflow

• Manual horizontal control , allowing precise adjustment according to the room configuration

This combination provides real control over comfort, without unnecessary complexity.

Actual performance in heating and air conditioning

Capacity and yield adapted to the Quebec climate

The 18,000 BTU cooling capacity is ideal for medium to large areas, while the heating performance remains remarkable:

• 14,400 BTU at -8°C

• 17,100 BTU at -15°C

• Certified operation down to -21°C , without unexpected shutdowns.

In several commercial installations in Laval and Longueuil , this model has made it possible to replace energy-intensive auxiliary electric systems, while maintaining a stable temperature during periods of intense cold.

Energy efficiency indices

• SEER2: 23.4

• HSPF2: 11.2

• COP at -8 °C: 3.64

These values ​​translate concretely into a significant reduction in electricity consumption , which is particularly valuable for buildings used over long periods of time.

R-32 refrigerant: efficiency and environmental responsibility

The FUJITSU Centauri uses R-32 gas , known for:

• A global warming potential reduced by approximately 68% compared to R-410A

• Improved thermal efficiency requiring less refrigerant

• Optimal compliance with current environmental guidelines in Quebec

For several institutional clients on the North Shore , this criterion was decisive in the choice of system, particularly when it is part of an energy modernization approach.

Acoustic comfort: an often underestimated point

The indoor noise level drops to as low as 31 dB(A) in quiet mode. In practice, this means:

• No disturbing noise in quiet environments (offices, treatment rooms, meeting rooms)

• Improved concentration and superior perceived comfort

Outside, the noise level remains controlled at 55 dB(A) , which facilitates installation in dense urban areas like Montreal .

Connectivity, control and integration with buildings

Advanced ordering options

Depending on the requirements, this system can be equipped with:

• Optional Wi-Fi for remote control

• Wired or infrared controls

• BACnet and Modbus compatible, ideal for commercial and multi-residential buildings

We have integrated this model into a centralized management system in an office building in Saint-Lambert , allowing the property manager to monitor performance and optimize operating schedules.

Functions useful in everyday life

• Economy mode

• Minimum heating mode

• Automatic defrosting

• Automatic restart after power failure

Key technical data to consider

• Indoor Unit : ABUH18KUAS

• Outdoor unit : AOUH18KUAS1

• AHRI : 215434548

• ENERGY STAR® – Cold Climate

• Maximum airflow : approximately 840 m³/h

• Dehumidification : 14.9 pt/h

• Power supply : 220 V | MCA 15 A | MOP 20 A

• Piping : 1/4 – 1/2 in

These parameters are systematically analyzed by our teams during the project design phase to ensure a perfectly sized HVAC installation.

LogisVert subsidy: a concrete financial advantage

At the time of writing, this model is eligible for a $1,728 LogisVert provincial grant (updated: November 26, 2025).
At AirGreen, we support our clients from Montreal to the South Shore in validating eligibility and preparing the required documents, in order to avoid frequent refusals or delays.

Why AirGreen recommends this model

Our field experience has taught us one thing: an excellent device that's poorly installed never delivers good results. By choosing AirGreen:

• The installation is carried out by certified refrigeration technicians , experienced in suspended systems.

• Thermal load calculations are done beforehand

• The diffusion and airflow parameters are adjusted on site

• The recommendations take into account the actual use of the building

This approach explains why the FUJITSU Centauri model is regularly chosen for our commercial and residential projects with high technical requirements.

Guarantee and peace of mind

• Compressor: 12 years

• Pieces: 12 years

• Labor: 0 years (extension possible)

We always clearly explain the additional warranty options to ensure consistent protection in line with the investment made.

Conclusion and personalized support

The FUJITSU Centauri 18,000 BTU ceiling-mounted heat pump is a reliable, proven solution perfectly suited to Quebec's climate and architectural realities. It combines performance, quiet operation, energy efficiency, and installation flexibility.
