SAMSUNG Premium FJM Heat Pump | 2-Zone | Outdoor: 24,000 BTU

A multi-zone heat pump designed for Quebec's climate realities

At AirGreen, we regularly install multi-zone systems in properties in Montreal, Laval, Longueuil, on the North Shore, and the South Shore, and the SAMSUNG Premium FJM series is among the solutions we recommend in very specific cases: when the client wants to control multiple zones independently without multiplying outdoor units.

This outdoor heat pump of 24,000 BTU (model AJ024DXS4CG/AA) can power 2 zones (expandable to 4) with remarkable precision. It is designed to maintain stable performance even during Quebec winters, with heating capacity down to -25°C, making it a suitable choice for local conditions.

Why choose a multi-zone heat pump like the Samsung FJM

A single outdoor unit, multiple controlled spaces

The main advantage of a multi-zone HVAC system is simple:
you can air condition and heat different rooms independently with a single outdoor unit.

Specifically, this means:

• A bedroom can be maintained at 22°C
• An office can remain cooler
• A rarely used room can be minimized to save energy

This is particularly useful in:

• Duplexes and triplexes in Montreal
• Homes with extensions on the South Shore
• Properties with floors or finished basements in Laval

According to the technical brochure, an FJM system allows for independent zone management, reducing overall consumption and improving comfort.

Real performance: what we observe in the field

At AirGreen, we have installed this model in several configurations. A concrete case:

Installation in Longueuil – renovated duplex

• 1 outdoor unit 24,000 BTU
• 2 wall-mounted units (living room + master bedroom)
• Inefficient old electric heating

Result:

• Reduced electricity consumption observed from the first winter
• Stable heating even on -20°C days
• No perceptible noise in the bedrooms

This confirms the technical data:
the system can maintain high heating capacity even at low outdoor temperatures.

Key technical data to know

Capacities and efficiency

• Cooling capacity: 24,000 BTU
• Heating capacity: up to 25,000 BTU
• Performance at -15°C: maintains nominal capacity
• SEER2: up to 23
• HSPF2: up to 10.4

These figures signify excellent energy efficiency, particularly relevant for reducing electricity costs in Quebec.

Advanced operation

• Dual Rotary BLDC Inverter compressor
• Soft-start to reduce electrical load
• Control via SmartThings (WiFi included)
• Electronic expansion valves for precise refrigerant control

Eco-friendly refrigerant

• Uses R-32, a gas with lower environmental impact
• Better energy efficiency compared to older systems

Robust design adapted to outdoor conditions

This heat pump is designed to last in Canadian conditions:

• Galvanized steel structure with resistant finish
• Corrosion protection tested up to 240 hours (ISO-9227 standard)
• Integrated heated defrost pan (important in winter)

At AirGreen, we always emphasize this point:
a high-performance heat pump must be designed for winter, not just for summer.

HVAC installation: critical elements not to overlook

Piping length and configuration

This model allows:

• Up to 230 feet total length
• Up to 82 feet per indoor unit
• Maximum height difference of 49 feet

This offers great flexibility but requires rigorous installation.

Frequent errors we often correct

• Incorrect sizing of indoor units
• Poor zone distribution
• Undersized electrical installation

These errors lead to:

• Loss of performance
• Excessive noise
• Premature wear

At AirGreen, we always perform a complete analysis before installation, including:

• Heat load calculation
• Electrical panel verification
• Optimization of unit positioning

Smart technology and advanced control

SmartThings: complete remote control

With the SmartThings app, you can:

• Adjust the temperature remotely
• Monitor your energy consumption
• Automate your comfort according to your habits

The brochure confirms that the system can even analyze usage habits to optimize energy consumption.

AI Energy Mode

• Energy consumption reduction of up to 20%
• Automatic adjustment of the compressor and airflow

Indoor comfort: much more than just heating

Compatibility with several types of indoor units

This system allows connection of:

• Classic wall-mounted units
• Ceiling cassettes
• Concealed ducts
• Floor consoles

This allows the solution to be adapted according to:

• Housing aesthetics
• Space constraints
• Budget

Noise and discretion

• Indoor: as low as 22 dB(A)
• Outdoor: approximately 52 dB(A)

In the majority of our installations in Montreal and Laval, clients are surprised by the very low noise level.

Subsidy and return on investment

LogisVert Subsidy

• Up to $1,824 (2025 update)

This significantly reduces the initial cost.

Observed profitability

In our typical projects:

• Return on investment between 3 and 6 years
• Significant savings on electric heating
