A Smart and Efficient Multi-Zone HVAC Solution for Greater Montreal Properties
In a context where homes and residential buildings in Montreal, Laval, Longueuil, North Shore, and South Shore have varied heating and cooling needs, 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-story homes, where independent temperature control is essential.
This specific model, identified as AJ024DXS4CG/AA (AHRI: 216372794), allows connecting up to 4 distinct indoor units, thus offering personalized comfort in each zone.
Understanding FJM Multi-Zone Technology: Flexibility and Advanced Control
A Single Compressor, Multiple Independent Spaces
Unlike traditional systems, FJM (Free Joint Multi) technology allows powering multiple indoor units with a single outdoor unit. This means:
- Reduced outdoor footprint
- Cleaner and more discreet installation
- Individual control of each room
- Real energy optimization
In a recent project in Boucherville (South Shore), we installed this system in an open-concept house with a mezzanine. The result: each zone (living room, bedrooms, office) operates independently, which avoids energy waste.
Heating Performance Adapted to Quebec's Climate
Real Capacity Down to -25°C
One of the most important criteria for our customers in Quebec is winter heating performance. This model offers:
- Effective heating down to -25°C
- Maintains nominal capacity at -15°C
- Heating power of 25,000 BTU
According to the manufacturer's technical data, the system maintains high capacity even in extreme conditions, making it a reliable choice for the harsh winters of Montreal and Laval.
Advanced Inverter Technology
The Twin BLDC Rotary Inverter compressor allows for:
- Precise power modulation
- Fewer ON/OFF cycles
- Optimized power consumption
- Extended lifespan
Energy Efficiency and Concrete Savings
High Performance Indicators
- SEER2: up to 23
- HSPF2: up to 10.4
- EER2: up to 14.55
These performances directly translate into savings on electricity bills, which are particularly significant in regions like the North Shore where homes are often larger.
Available Subsidies
This model is eligible for the LogisVert subsidy of $1824, which significantly reduces the initial cost.
HVAC Installation: What You Need to Know (AirGreen Field Feedback)
Real Example – Installation in Laval
We recently installed this heat pump in a duplex in Laval with the following constraints:
- Significant total piping length
- Three floors to serve
- Limited outdoor access
Thanks to the following features, the installation was efficient:
- Maximum piping length: 230 feet
- Vertical separation: up to 49 feet
- Simplified connections without complex branching
Result: a clean, fast installation without major structural modifications.
Superior Indoor Comfort and Remarkable Silence
Very Low Sound Level
- Indoor: as low as 22 dB(A)
- Outdoor: approximately 52 dB(A)
In several projects in Longueuil, customers specifically chose this model for its quiet operation, especially for bedrooms and offices.
Intelligent Air Distribution
Compatible units allow for:
- Automatic louver control (vertical and horizontal)
- Uniform diffusion throughout the room
- Elimination of cold or hot spots
Connectivity and Smart Control
Integrated WiFi with SmartThings
Each unit can be controlled via the Samsung SmartThings app:
- Remote temperature adjustment
- Energy consumption monitoring
- Automation based on habits
In a project in Montreal (Plateau Mont-Royal), a client automated their system to reduce consumption during work hours — a concrete optimization.
Indoor Unit Compatibility: A Major Advantage
The FJM system is compatible with several types of units:
- WindFree™ Wall-Mounted
- Consoles (ideal for radiator replacement)
- Ceiling Cassettes
- Ductless or Mini-Ducts
This allows for perfect adaptation of the solution to each residential configuration.
According to the technical documentation, different combinations are possible depending on the connected capacities, offering 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. 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.
