A High-Performance Central Solution Designed for Quebec Winters
At AirGreen, we daily install HVAC systems tailored to the demanding climate realities of Greater Montreal, Laval, Longueuil, as well as the North Shore and South Shore. The FUJITSU CENTAURI XLTH R32 4-ton (48000 BTU) electric furnace fits this logic: a central solution designed to offer stable heating performance down to -30°C, while maintaining excellent energy efficiency.
This model, combined with the compatible AOUH48KUAH1 central heat pump, represents a strategic option for homeowners who wish to optimize their comfort while reducing their energy consumption.
Understanding the True Power of a FUJITSU CENTAURI XLTH Furnace
Thermal Capacity and Performance in Real Conditions
Unlike many systems that rapidly lose efficiency at low temperatures, this furnace stands out for its measured and reliable performance:
- Nominal Capacity: 48,000 BTU
- Power at -8°C: 34,000 BTU
- Power at -15°C: 51,000 BTU
- Guaranteed operation down to -30°C
In our installations in Montreal and Montérégie, we have found that this type of system maintains constant comfort even during extreme cold spells. This prevents frequent short cycling and improves the overall durability of the equipment.
Advanced Energy Efficiency
The FUJITSU CENTAURI XLTH stands out with solid technical indicators:
- SEER2: 19.03
- HSPF2: 10.21
- EER2: 11.22
- COP at -8°C: 1.96
These data indicate an ability to produce more thermal energy than it consumes, a key factor in reducing operating costs in regions like Laval or the North Shore, where winters are long.
HVAC Installation: What We Do Differently at AirGreen
A Rigorous Approach from the First Visit
During a recent project in Longueuil, our team replaced an inefficient old central system with this FUJITSU furnace. The main challenge: a restricted mechanical space with poorly optimized existing ducts.
Our intervention included:
- Complete re-evaluation of airflow (CFM: 1160 optimized)
- Duct adjustment to reduce pressure losses
- Installation in compliance with RBQ standards with electrical protection (MOP: 40A)
Result: an immediate improvement in thermal comfort and a measured reduction in energy consumption.
Technical Installation Details
- Indoor dimensions: 21 x 21 x 48 inches
- Voltage: 220V
- Piping: 3/8 - 5/8
- Dehumidification: 4.7 pints/hour
These specifications allow for flexible integration into most residences in Greater Montreal, including single-family homes and duplexes.
Why R-32 Refrigerant Changes the Game
The transition to R-32 represents a significant evolution in the HVAC field:
- Reduced environmental impact
- Improved thermal efficiency
- Reduced refrigerant charge needed
In several projects in Laval and on the South Shore, we have observed a notable improvement in overall performance compared to older R-410A systems.
Subsidies and Return on Investment
LogisVert Program: A Concrete Opportunity
The FUJITSU CENTAURI XLTH furnace is eligible for a subsidy of up to $4080 via the LogisVert program (updated November 2025).
In a real case in Boucherville, a client was able to:
- Reduce their initial installation cost
- Achieve a return on investment in less than 5 years
- Improve the value of their property
ENERGY STAR Eligibility
- Certified ENERGY STAR
- Certified ENERGY STAR Cold Climate
This confirms its suitability for cold climates like those of Montreal and the North Shore.
Sound Comfort and Quality of Life
Optimized Sound Level
- Indoor: 34 to 51 dB(A)
- Outdoor: 60 dB(A)
In a recent installation in Montreal East, the client immediately noticed the difference from their old system: much quieter operation, especially in continuous heating mode.
Common Mistakes to Avoid When Choosing an Electric Furnace
Underestimating Real Needs
Incorrect sizing remains the most frequent error. A 4-ton unit like this is ideal for:
- Large homes
- Multi-unit dwellings
- Open spaces requiring uniform distribution
Neglecting Installation Quality
Even the best equipment loses efficiency if poorly installed. At AirGreen, every installation is carried out by experienced refrigeration technicians, with particular attention to detail:
- Duct sealing
- System balancing
- Complete post-installation verification
Field Testimonial: Project Completed in Laval
During a project in a triplex in Laval, we replaced an aging system with this FUJITSU CENTAURI XLTH furnace.
Challenges encountered:
- Partially obstructed ducts
- Uneven air distribution between floors
Solutions provided:
- Complete cleaning and recalibration of the network
- Airflow adjustment per zone
Result:
- Uniform temperature in all three units
- Significant reduction in occupant complaints
- Stabilized energy consumption
