A high-performance multi-zone solution for Quebec's climate realities
At AirGreen, we regularly install multi-zone systems in homes in Montreal, Laval, Longueuil, as well as on the North Shore and the South Shore, and the SAMSUNG Premium FJM 24,000 BTU Heat Pump is one of the most strategic configurations for modern homes.
This AJ024DXS4CG/AA outdoor model is designed to serve up to 3 separate zones, allowing precise temperature control in different rooms. Unlike traditional centralized systems, this approach offers real flexibility, especially in properties with several floors, additions or needs that vary from room to room.
Why choose an FJM multi-zone system from AirGreen
Smart comfort management in every room
The FJM (Free Joint Multi) multi-zone system is based on a single outdoor compressor serving several indoor units. This allows:
- A different temperature in each zone
- A reduction in energy losses
- A better fit with your daily routines
In a recent installation, we integrated this system into an intergenerational home. The result: each floor enjoys independent comfort, with no compromise on overall performance.
Heating performance down to -25 °C
A critical point for customers in Quebec is the actual capacity in winter.
- Efficient heating down to -25 °C, according to Samsung
- Capacity maintained at -15 °C, according to Samsung
- Technology designed for cold climates (ENERGY STAR® Cold Climate)
According to the manufacturer's technical data, the system provides stable heating capacity even at very low temperatures. This makes it a reliable solution to replace or supplement an existing system.
Listed on NEEP (AHRI 216372794): at -8 °C, rated capacity of 15,200 BTU/h (COP 2.89) and up to 25,000 BTU/h at full output; at -15 °C, up to 25,000 BTU/h (COP 1.85); at -25 °C, up to 18,000 BTU/h (COP 1.61).
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
In practical terms, these values mean:
- Lower electricity consumption
- Lower operating costs
- Access to Hydro-Québec's LogisVert program: indicative LogisVert amount of $1,824 (Hydro-Québec list of October 14, 2026). Only Hydro-Québec confirms the assistance granted.
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 refrigerant line length: 230 feet
This last point is particularly important: it allows great flexibility when installing in complex homes or multi-unit buildings.
Advanced inverter compressor technology
The Twin BLDC Inverter compressor adjusts its output in real time:
- Fewer ON/OFF cycles
- Stable temperature
- Less mechanical wear
This translates directly into a longer system life.
Smart control and connectivity
With Wi-Fi and SmartThings integration, users can:
- Control the temperature remotely
- Track energy consumption
- Adjust settings automatically
According to the Samsung brochure, AI Energy mode optimizes the settings automatically.
At AirGreen, we systematically configure these options during commissioning to ensure an optimal experience.
Real installation: AirGreen field experience
Completed Project
We installed this system in a triplex:
Configuration:
- 3 wall 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 with no multiple branches, we simplified the installation while maintaining maximum efficiency.
Result:
- Clean, discreet installation
- Uniform performance in all zones
- Customer very satisfied with the comfort and quiet operation
Flexible choice of compatible indoor units
This system is compatible with several types of units:
- WindFree™ wall units
- Ceiling cassettes
- Ducted units (Slim Duct)
- Floor consoles
This makes it possible to adapt each zone according to:
- The available space
- The desired look
- The customer's specific needs
In another project, we combined a wall unit in the living room with a ducted unit for the bedrooms to keep the system as discreet as possible.
Concrete benefits for Quebec homeowners
1. Lower energy costs
Thanks to inverter modulation and independent zones.
2. Personalized comfort
Each family member can adjust their own room.
3. Simplified installation
Less work than a complete central system.
4. An ideal solution for renovations
Perfect for replacing electric baseboards or an aging system.
Common mistakes to avoid (AirGreen field feedback)
Incorrect sizing
A multi-zone system must be sized correctly. Too powerful or undersized = inefficiency.
Poor BTU distribution
Each room must receive a suitable capacity.
Poorly optimized refrigerant lines
Poorly planned line lengths can reduce performance.
At AirGreen, every project starts with a detailed technical visit to avoid these mistakes.

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. Indicative amount: only Hydro-Québec confirms the assistance granted. 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?
Samsung 12-12-6 warranty: 12 years on the compressor, 12 years on parts and 6 years on labour. 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.
