FUJITSU ORION XLTH KZAH R-32 Wall Mounted Heat Pump | 12,000 BTU | Montreal, Laval, Longueuil, South Shore & North Shore

High-performance wall-mounted heat pump for real Quebec winters

In Greater Montreal, a wall-mounted heat pump shouldn't just provide air conditioning for a few weeks a year. Its primary function is to ensure stable, reliable, and economical heating for extended periods, often in harsh weather conditions such as cold winds, freezing rain, and prolonged periods of extreme cold. The FUJITSU ORION XLTH KZAH R-32 | 12,000 BTU was specifically designed for this type of climate.

At AirGreen, we install this model in a wide variety of contexts:

• urban condos in Montreal;

• single-family homes in Laval;

• semi-detached and duplex houses in Longueuil;

• properties on the North Shore and the South Shore .

Everywhere, the observation is the same: this wall-mounted heat pump offers four-season comfort , quiet operation and remarkably controlled electricity consumption.

An optimized HVAC investment: LogisVert subsidy and extended warranties

Upgrading to a new generation heat pump like the FUJITSU ORION XLTH 12,000 BTU is not just a comfort choice: it is also a smart financial investment.

Designed for extreme cold: performance that exceeds its rated capacity

In Greater Montreal, it's common for the temperature to drop below -20°C , sometimes for several days in a row. Many standard appliances end up only maintaining the minimum temperature, or require the assistance of an expensive space heater.

The FUJITSU ORION XLTH KZAH R-32 | 12,000 BTU stands out because of:

• an operating range in heating mode down to −26 °C ;

• a nominal heating capacity of 16,000 BTU , with modulation between 3,500 and 23,600 BTU;

• Inverter technology continuously adjusts the compressor power according to the actual needs of the room.

This adjustment is essential:

• It limits unexpected starts and stops;

• It reduces mechanical wear;

• It maintains a stable temperature, without sudden changes between too hot and too cold.

In practice, our customers find that the system continues to heat efficiently at temperatures where other heat pumps struggle, which makes a real difference during periods of intense cold.

R-32: a modern, more environmentally friendly and more efficient refrigerant

The ORION XLTH series uses R-32 refrigerant, which is gradually replacing R-410A in new generations of HVAC systems.

Its main advantages:

• Reduced environmental impact : R-32 has a significantly lower global warming potential than R-410A, making it a more responsible choice in the long term.

• Increased efficiency : R-32 often delivers superior performance in equivalent quantities. This translates into better energy use and therefore lower electricity bills.

• Sustainable transition : investing in an R-32 heat pump means anticipating regulatory changes, restrictions on certain older refrigerants and the possible increase in their costs.

For a family or a small building owner looking to modernize their system, this heat pump represents a concrete step towards more sustainable comfort , without compromising on performance.

Energy efficiency that is reflected in the bill

The performance values ​​of the FUJITSU ORION XLTH 12,000 BTU clearly place it in the category of highly efficient heat pumps:

• SEER2: 30.5 – this means excellent air conditioning efficiency ;

• HSPF2: 12.7 – very good efficiency in heating mode;

• EER2: 16.0 – high instantaneous efficiency;

• ENERGY STAR® and Cold Climate certifications – guarantees of performance and compliance with the rigorous standards of northern climates.

For a homeowner, these figures simply translate to:

• reduced consumption in summer, even during heat waves;

• more economical heating in winter, compared to electric baseboard heaters or an old, poorly sized system;

• consistent performance over several years, provided that basic maintenance is carried out.

A quiet heat pump, suitable for residential environments

Thermal comfort is not measured solely in degrees: silence is just as important, especially in a condo, a plex or a house where the rooms are close together.

The FUJITSU ORION XLTH 12,000 BTU was designed to operate discreetly:

• 23 dB(A) indoors at the lowest setting, which is a sound level close to the silence of a quiet room;

• 47 dB(A) outside , which allows installation in a courtyard, on a balcony or near a terrace without disturbing the occupants or neighbors.

This is a particularly appreciated point in:

• the dense neighborhoods of Montreal (Plateau-Mont-Royal, Rosemont, Verdun, Villeray);

• residential areas of Laval where houses are close together;

• the semi-detached houses and condominiums of Longueuil, Brossard and Boucherville.

A discreet and durable indoor unit

The FUJITSU ORION XLTH indoor wall unit integrates easily into various types of decor. Its understated design, with clean lines, makes it a device that blends well into a living room, office, or bedroom.

From a technical point of view:

• the heat exchanger benefits from a special treatment to improve its corrosion resistance;

• The fan offers several speeds (including a Quiet mode and a Powerful mode), allowing you to switch from silent comfort to rapid cooling depending on the situation;

• The filters are washable and easily accessible, which simplifies maintenance for the owner.

For open-plan living areas, the Auto mode adjusts the speed according to the actual demand, thus avoiding unpleasant drafts.

An outdoor unit ready for snow, ice and wind

In Quebec's climate, the behavior of the outdoor unit is crucial. It must manage:

• snow and ice;

• freeze and thaw cycles;

• the winds are sometimes very cold.

The ORION XLTH series was designed for these conditions:

• heated base to limit ice buildup in the crankcase;

• automatic defrosting optimized to maximize heating operating time;

• Compact chassis allowing for installation on a raised surface or on a wall bracket, away from snow accumulation.

At AirGreen, we choose the position of the outdoor unit taking into account:

• the direction of the prevailing winds;

• water drainage during ice melt;

• accessibility for future maintenance;

• aesthetic and regulatory constraints (distance from the property line, co-ownership rules, etc.).

Flexible pipe lengths and careful installation

The FUJITSU ORION XLTH 12,000 BTU comes with a factory refrigerant pre-charge for a certain standard piping length (up to approximately 15 m). The maximum allowable length is greater (up to 25 m), allowing for considerable flexibility in the placement of the outdoor unit.

This allows, for example:

• to install the outdoor unit in the backyard while the indoor unit is located at the front;

• to circumvent architectural obstacles;

• to conceal the piping in aluminium pipe covers for a more aesthetically pleasing result.

Our teams adjust the refrigerant charge when the actual line length exceeds the factory pre-charge. This meticulous adjustment is essential for:

• guarantee heating and air conditioning capacity;

• avoid overconsumption of energy;

• to extend the compressor's lifespan.

Wi-Fi connectivity and home automation integration

Integrated Wi-Fi connectivity allows you to control the heat pump remotely from a phone or tablet:

• temperature setpoint change while traveling;

• activation or deactivation of the device before arriving home;

• Time-based programming to optimize consumption.

For more complex buildings, it is also possible to integrate the heat pump into a centralized management system using BACnet or Modbus compatible interfaces. This opens the door to:

• a grouped control of several units;

• more advanced energy management;

• better visibility into the operation of different devices in a small building or shop.

AirGreen can also add, as needed, a wall controller , a specific thermostat or other control accessories.

Concrete examples of AirGreen installations with the FUJITSU ORION XLTH 12,000 BTU

Two-level condo in Rosemont–La Petite-Patrie
The homeowner wanted to improve comfort in the semi-basement, which was considered too cold in winter, while also effectively air-conditioning the open-concept main floor. We installed the indoor unit at the top of the stairs, with 1/4–3/8 piping concealed in pipe covers that matched the exterior brick. After a few weeks of use, the client noted:

• a more consistent temperature between the two levels;

• a reduction in the electricity bill, especially during air conditioning season;

• an internal noise level significantly lower than that of its previous system.
