A smart, high-performance multi-zone HVAC solution for Greater Montreal properties
Homes and residential buildings in Montreal, Laval, Longueuil, the North Shore and the South Shore have widely varying heating and cooling needs, and the SAMSUNG Premium FJM 4-zone 24,000 BTU heat pump stands out as a particularly strategic solution. At AirGreen, we regularly install this type of system in multi-room projects, condos, duplexes and multi-storey houses, where independent temperature control is essential.
This specific model, identified as AJ024DXS4CG/AA (AHRI: 216372794), can connect up to 4 separate indoor units, giving each zone its own personalized comfort.
Understanding FJM multi-zone technology: flexibility and advanced control
One compressor, several independent spaces
Unlike traditional systems, FJM (Free Joint Multi) technology powers several indoor units from a single outdoor unit. This means:
- Less equipment outside
- A cleaner, more discreet installation
- Individual control of each room
- Real energy optimization
In a recent project, we installed this system in an open-concept house with a mezzanine. The result: each zone (living room, bedrooms, office) runs independently, which avoids wasting energy.
Heating performance suited to Quebec's climate
Real capacity down to -25 °C
For our clients in Quebec, winter heating performance is one of the most important criteria. This model offers:
- Efficient heating down to -25 °C, according to Samsung
- Rated capacity maintained at -15 °C, according to Samsung
- Heating output of 25,000 BTU
According to the manufacturer's technical data, the system maintains high capacity even in extreme conditions, which makes it a reliable choice for harsh winters in Montreal and Laval.
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 Inverter technology
The Twin BLDC Rotary Inverter compressor provides:
- Precise modulation of output
- Fewer ON/OFF cycles
- Optimized power consumption
- A longer service life
Energy efficiency and grants
High performance ratings
- SEER2: up to 23
- HSPF2: up to 10.4
- EER2: up to 14.55
This performance translates directly into savings on electricity bills.
Available rebates
For this model, the indicative LogisVert amount is $1,824 (Hydro-Québec list of October 14, 2026), which considerably lowers the upfront cost. Only Hydro-Québec confirms the assistance granted.
HVAC installation: what you need to know (AirGreen field experience)
Real example
We recently installed this heat pump in a duplex with the following constraints:
- A long total piping length
- Three floors to serve
- Limited outdoor access
Thanks to the following features, the installation went smoothly:
- Maximum piping length: 230 feet
- Vertical separation: up to 49 feet
- Simplified connections with no complex branching
The result: a clean, fast installation with no major structural changes.
Superior indoor comfort and remarkably quiet operation
Very low sound level
- Indoor: as low as 23 dB(A)
- Outdoor: about 52 dB(A)
In several projects, clients specifically chose this model for its quiet operation, especially for bedrooms and offices.
Smart air distribution
Compatible units provide:
- Automatic louvre control (vertical and horizontal)
- Even air distribution throughout the room
- No more cold or hot spots
Connectivity and smart control
Built-in Wi-Fi with SmartThings
Each unit can be controlled through the Samsung SmartThings app:
- Remote temperature adjustment
- Energy use tracking
- Automation based on your routines
In one project, a client automated the system to reduce consumption during working hours, a practical optimization.
Indoor unit compatibility: a major advantage
The FJM system is compatible with several types of units:
- WindFree™ wall units
- Consoles (ideal for replacing radiators)
- Ceiling cassettes
- Ductless or slim ducted units
This makes it possible to tailor the solution to each residential layout.
According to the technical documentation, different combinations are possible depending on the connected capacities, which offers great flexibility for complex projects.

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 4 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.
