A High-Performance Multi-Zone Solution for Quebec's Climate Realities
At AirGreen, we regularly install multi-zone systems in residences in Montreal, Laval, Longueuil, as well as on the North Shore and South Shore, and the SAMSUNG Premium FJM 24,000 BTU Heat Pump is one of the most strategic configurations for modern homes.
This outdoor model AJ024DXS4CG/AA is designed to power up to 3 distinct zones, allowing precise temperature control in different rooms. Unlike traditional centralized systems, this approach offers real flexibility, particularly in properties with multiple floors, extensions, or varying needs between rooms.
Why choose an FJM multi-zone system from AirGreen
Intelligent comfort management in every room
The principle of the FJM (Free Joint Multi) multi-zone system is based on a single outdoor compressor powering multiple indoor units. This allows for:
- A different temperature per zone
- A reduction in energy losses
- Better adaptation to lifestyle habits
In a recent installation in Boucherville (South Shore), we integrated this system into an intergenerational home. The result: each floor benefits from independent comfort, without compromising overall performance.
Heating performance down to -25°C
A critical point for customers in Quebec is real winter capacity.
- Effective heating down to -25°C
- Capacity retention at -15°C
- Technology adapted to cold climates (ENERGY STAR® Cold Climate)
According to manufacturer technical data, the system offers stable heating capacity even at very low temperatures. This makes it a reliable solution to replace or complement an existing system.
Advanced energy efficiency
This model stands out for its high performance:
- SEER2 up to 23
- HSPF2 up to 10.4
- EER2 up to 14.55
These values concretely mean:
- Less electricity consumption
- Reduction in operating costs
- Eligibility for grants like LogisVert ($1824)
In several projects in Laval, our clients have observed a significant decrease in their energy bill from the very first season.
Essential technical details for a successful HVAC installation
Key specifications
- Capacity: 24,000 BTU
- Voltage: 220V
- MCA: 36A / MOP: 40A
- Refrigerant: R-32 (low environmental impact)
- Outdoor sound level: 52 dB(A)
- Maximum line length: 230 feet
This last point is particularly important: it allows for great flexibility during installation in complex homes or multi-unit buildings.
Advanced Inverter compressor technology
The Twin BLDC Inverter compressor adjusts its power in real time:
- Fewer ON/OFF cycles
- Stable temperature
- Reduced mechanical wear
This directly translates into increased system longevity.
Control system and smart connectivity
With WiFi and SmartThings integration, users can:
- Control temperature remotely
- Monitor energy consumption
- Automatically adjust settings
According to the Samsung brochure, the AI Energy mode can even reduce consumption by up to 20% by optimizing settings.
At AirGreen, we systematically configure these options during commissioning to ensure an optimal experience.
Real installation: AirGreen's field experience
Project in Montreal (Plateau Mont-Royal)
We installed this system in a triplex:
Configuration:
- 3 wall-mounted units (9,000 + 12,000 + 12,000 BTU)
- Distribution over 2 floors
Challenges encountered:
- Limited outdoor space
- Complex refrigerant line routing
Solution:
Thanks to the home-run piping system without multiple branches, we simplified the installation while maintaining maximum efficiency.
Result:
- Clean and discreet installation
- Uniform performance in all zones
- Client very satisfied with comfort and quietness
Flexibility of compatible indoor units
This system is compatible with several types of units:
- Wall-mounted WindFree™
- Ceiling cassettes
- Ducted units (Slim Duct)
- Floor consoles
This allows each zone to be adapted according to:
- Available space
- Desired aesthetics
- Specific client needs
In a project in Longueuil, we combined a wall-mounted unit in the living room and a ducted unit for the bedrooms to maximize discretion.
Concrete benefits for homeowners in Quebec
1. Reduced energy costs
Thanks to Inverter modulation and independent zones.
2. Personalized comfort
Each family member can adjust their room.
3. Simplified installation
Less work than a complete central system.
4. Ideal solution for renovation
Perfect for replacing electric baseboards or an aging system.
Common mistakes to avoid (AirGreen field feedback)
Incorrect sizing
A multi-zone system must be correctly calculated. Too powerful or insufficient = inefficiency.
Poor BTU distribution
Each room must receive an appropriate capacity.
Non-optimized duct installation
Poorly planned lengths can reduce performance.
At AirGreen, every project begins with a detailed technical visit to avoid these errors.

What people ask us about multi-zone systems.
Can I heat one room and cool another at the same time?
No. On a multi-zone system like this one, every head works in the same mode, heating or cooling. Each room still keeps its own set temperature.
What happens when every room calls for heat?
They share the outdoor unit’s capacity: 15,200 BTU/h at −8 °C, 25,000 at −15 °C.
How many heads can I connect?
Up to 4 on this outdoor unit. This product is configured for 3 heads.
How much is the LogisVert grant?
$1,824 according to Hydro-Québec’s list of October 1, 2026. The grant never exceeds 100 % of the cost before taxes; apply within 9 months of installation.
Is it ENERGY STAR certified?
Yes, cold climate, ID 3891561. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.
Down to what temperature does it heat?
Down to −25 °C.
Is it noisy?
Indoors, the reference head goes down to 22 dB(A). Outdoors, 52 dB(A): we place the unit away from bedroom windows.
Why a multi-zone instead of several wall units?
One outdoor unit on the wall and one circuit. In return, the rooms share the capacity, and if the outdoor unit stops, every zone stops.
What does the warranty cover?
Our sheet lists 12 years on the compressor and 12 years on parts; labour is not included by the manufacturer. AirGreen extended warranty: possible.
A multi-zone system is planned room by room. At your home.
We measure every room, draw the line route and choose the right head for each zone. The on-site estimate is free and the quote arrives within 24 h.
