A ducted heat pump designed for projects where every detail matters

At AirGreen, we work daily on HVAC projects where expectations go far beyond simple heating and cooling. In several high-end residences in Montreal , multi-unit buildings in Laval , commercial buildings in Longueuil , as well as new constructions and complex renovations on the North and South Shores, the FUJITSU CENTAURI R32 | 42000 BTU Ducted Heat Pump stands out as a structuring, reliable and technically sound solution.

This ducted , medium-static-pressure system is not intended for standard projects. It is designed for buildings where uniform, invisible, silent, and stable air distribution is desired, even in demanding climatic conditions. It is an HVAC solution built to last, with a clear engineering logic adapted to the realities of Quebec's climate.


A ducted design conceived for real comfort, not theoretical.

Efficient heating down to -21°C, without interruption

One of the main challenges our customers face is maintaining stable heating in winter. The FUJITSU CENTAURI R32 | 42000 BTU Ducted Heat Pump is designed to operate in heating mode down to -21°C , without an automatic low-temperature shut-off. In practice, this means the system continues to operate even where many traditional heat pumps experience a significant drop in efficiency.

In the field, at AirGreen, we observed this behavior during installations in Laval and on the South Shore , particularly in buildings with large heated areas. Even during prolonged periods of intense cold, the heat distribution remains homogeneous, without excessive cycling or perceptible discomfort.

The available power allows for handling significant loads:

  • 42,000 BTU nominal

  • 32,000 BTU at -8°C

  • 37,000 BTU at -15°C

These values ​​provide a significant safety margin, particularly in buildings with high ceilings, open floors or high thermal inertia.

Average static pressure: a decisive advantage in renovation

The ability to handle static pressures up to 0.8 inWG is a major advantage for renovation projects. In several Montreal buildings, we were able to integrate this system into existing, sometimes complex, ductwork networks without having to redo the entire distribution system.

This flexibility allows:

  • to optimize the use of existing ducts,

  • to reduce structural work,

  • to maintain a constant airflow even in complex configurations.

For multi-unit residential buildings or commercial buildings, this characteristic becomes crucial to ensure consistent performance from one space to another.


Measurable and consistent energy performance

Yields adapted to Quebec realities

The FUJITSU CENTAURI R32 | 42000 BTU ducted heat pump offers energy performance that meets current market requirements:

  • ENERGY STAR® Certification

  • ENERGY STAR® Cold Climate Certification

  • SEER2: 17.3

  • HSPF2: 10.2 / 8.2

  • COP at -8 °C: 3.66

In projects carried out by AirGreen in Longueuil and on the North Shore , these indicators translate into a concrete reduction in annual electricity consumption, particularly when the system replaces direct electric heating or an old, poorly modulating HVAC system.

R-32 refrigerant: efficiency and responsibility

The choice of R-32 is not insignificant. It allows:

  • a significant reduction in global warming potential

  • improved thermodynamic efficiency

  • a lower refrigerant charge for equivalent power.

For owners concerned about the sustainability of their investment, this refrigerant represents a smart compromise between performance, regulatory compliance and environmental impact.


Silence, comfort and even diffusion

Quiet operation, even under high load

Acoustic comfort is often underestimated when selecting a ducted HVAC system. This model allows for indoor operation as low as 29 dB(A) depending on the fan speed. In several residential projects in Montreal , this has made it possible to install the unit above bedrooms or offices without generating noise.

The outdoor unit, with a noise level around 57 dB(A) , complies with urban and municipal constraints, even in dense residential areas.

High and stable airflow

With an airflow of up to 1,501 CFM , air distribution is constant and balanced. This capability is particularly appreciated in:

  • open-plan houses,

  • shops with high ceilings,

  • buildings with multiple zones served by the same network.

Unlike undersized systems, this avoids cold zones, temperature differences and comfort-related complaints.


Controls, connectivity and advanced integration

A flexible control platform

This system can be integrated with several types of controls:

  • wired touchscreen controls

  • infrared remote controls,

  • Optional Wi-Fi connectivity via the AIRSTAGE ecosystem,

  • integration with building management systems via BACnet or Modbus .

At AirGreen, we have integrated this heat pump into commercial environments in Longueuil , allowing centralized management of schedules, temperatures and periods of energy reduction.

Integrated security and increased reliability

The presence of a refrigerant leak detection sensor directly integrated into the indoor unit contributes to building safety and facilitates diagnostics during HVAC maintenance. This is a particularly valuable feature in multi-unit residential and institutional buildings.


HVAC Installation: The AirGreen Difference

A methodical and rigorous approach

Installing a ducted heat pump of this caliber requires much more than a simple connection. At AirGreen, every project includes:

  • a detailed analysis of thermal loads,

  • the assessment of the existing conduit network,

  • the precise calculation of pressure losses,

  • accessibility planning for future HVAC maintenance.

This approach allows the system's potential to be fully exploited and ensures its longevity.

Concrete examples of achievements

  • Renovated triplex in Montreal : replacement of an old forced air system with a FUJITSU CENTAURI R32 ducted heat pump, with a noticeable improvement in comfort on the upper floors.

  • Commercial building in Laval : integration into an existing ducted network, reduction of ambient noise and improved thermal stability.

  • New residence on the South Shore : fully concealed installation, no visible wall units, uniform diffusion throughout all rooms.


Subsidies and long-term value

The FUJITSU CENTAURI R32 | 42000 BTU Ducted Heat Pump is eligible for the LogisVert provincial grant , which can reach up to $3,840 depending on the applicable conditions. For many of our clients, this financial assistance has allowed them to choose a superior quality ducted system without compromise.

At AirGreen, we support our clients in the administrative procedures in order to maximize the obtaining of available subsidies.
