A High-Performance Central Solution Designed for Quebec's Climate
At AirGreen, we observe a clear evolution in homeowners' expectations in Montreal, Laval, Longueuil, and on both the South and North Shores: they are looking for central HVAC systems capable of providing consistent comfort, even during periods of intense cold, while reducing their energy consumption. The FUJITSU CENTAURI R32 4-ton (48000 BTU) electric furnace precisely meets these requirements.
This model is part of the Centauri series by AIRSTAGE, renowned for its reliability in cold climates and installation flexibility. It is a complete solution, designed to work with a central heat pump (AOUH48KUAS1), offering heating and cooling in a single integrated system.
Technology Adapted to the Realities of Montreal, Laval, and Longueuil
Exceptional Heating Performance Down to -21°C
Unlike many standard central systems, this unit maintains stable performance even when temperatures drop drastically. It is capable of providing:
- Nominal power: 48,000 BTU
- Power at -8°C: 37,200 BTU
- Power at -15°C: 41,000 BTU
- Reliable operation down to -21°C
According to Fujitsu's technical data sheet, this series is specifically designed for cold climates without a lockout device, ensuring continuous heating even in extreme conditions.
In our installations in Boucherville and Laval, we have observed that this type of system helps avoid frequent auxiliary heating cycles, thereby reducing energy costs.
Superior Energy Efficiency
This model stands out for its high energy performance:
- SEER2: 17.03
- HSPF2: 19.615
- EER2: 19.52
- ENERGY STAR® certified (including cold climate)
These figures concretely translate into significant savings on energy bills. Fujitsu indicates that inverter technology continuously adjusts power according to real needs, thereby improving overall efficiency.
At AirGreen, we have documented reductions of up to 25 to 30% on heating costs for properties equipped with this type of central system.
Flexible Installation Adapted to Real Projects
Multiposition Configuration: A Key Advantage
The CENTAURI AMUH48KUAS is a multiposition air handler:
- Vertical flow (up or down)
- Horizontal flow (left or right)
- Easy adaptation to basements, attics, or confined technical spaces
This flexibility is essential in renovation projects in Montreal where space constraints are common.
Concrete AirGreen Example
During a project in Longueuil, a client had very limited mechanical space. Thanks to the horizontal configuration of this unit, we were able to:
- Install the furnace without major structural modifications
- Optimize existing air distribution
- Reduce installation time by nearly 20%
Indoor Comfort and Air Quality
Optimized Airflow and Circulation
With a flow rate of up to 1600 CFM, this unit ensures uniform air distribution throughout the house.
It also offers:
- 4 fan speeds + automatic mode
- Adjustable static pressure
- Compatibility with ERV/HRV systems
Efficient Dehumidification
- Capacity: 4.7 pints/hour
This point is particularly important for homes in Montreal and Laval, where summer humidity can become problematic.
Quiet Sound Level
- Indoor: 34 to 51 dB(A)
- Outdoor: 59 dB(A)
According to technical data, some modes reach levels as low as 30 dB(A), making it a very quiet solution.
In high-end residential projects on the South Shore, this criterion is often decisive for clients.
R-32 Refrigerant: A Strategic Choice
The FUJITSU CENTAURI uses R-32, a modern refrigerant with:
- 68% reduction in global warming potential (GWP) compared to R-410A
- Better thermal efficiency
- Reduced refrigerant quantity
At AirGreen, we favor this type of technology for clients wishing to reduce their environmental footprint without compromising performance.
Advanced Connectivity and Integration
Smart Control Options
This unit allows full integration with various systems:
- WiFi (optional)
- 24V compatible thermostat
- BACnet and Modbus protocols
- AIRSTAGE mobile application
This allows for intelligent system management, particularly useful in:
- Multi-unit homes
- Rental properties
- Commercial buildings
Accessories and Customization
The Centauri series offers a wide range of options:
- Auxiliary heating (2 kW to 16 kW)
- Touchscreen wall controllers
- Remote temperature sensors
- Home automation interfaces
During a commercial project in Montreal, we integrated this unit into a centralized building management system, allowing precise control of each zone.
Subsidies and Return on Investment
LogisVert Subsidy
- Up to $4,464 (updated November 2025)
This type of installation is eligible for energy assistance programs, which significantly reduces the initial cost.
At AirGreen, we systematically support our clients with:
- Eligibility validation
- Document preparation
- Application follow-up
What to Avoid (AirGreen Field Experience)
Common Mistakes
-
Undersizing of the system
→ leads to overconsumption and discomfort -
Incorrect airflow configuration
→ reduces overall efficiency -
Installation without ductwork balancing
→ uneven heat distribution
We have corrected several installations in Laval where these errors had been made, demonstrating the importance of professional installation.
