FUJITSU ORION XLTH KZAH R-32 Wall Mounted Heat Pump | 15,000 BTU | Montreal, Laval, Longueuil, South Shore & North Shore

A high-end wall-mounted heat pump designed for Quebec's climate

At AirGreen, we install a large number of wall-mounted heat pumps in the Greater Montreal area every year. Over time, we've developed a clear understanding of which units age well, which provide true comfort in winter, and which deliver real energy savings. The FUJITSU ORION XLTH KZAH R-32 15,000 BTU is one of the models we regularly recommend to our clients who want a reliable, quiet, and long-lasting solution.

This single-zone wall unit was designed for Quebec's harsh winters: efficient heating down to -26°C , intelligent defrost management, cold-weather electronics, and modern R-32 refrigerant for improved energy efficiency. Combined with a very high seasonal efficiency ( SEER2 27.5, HSPF2 12.7, EER2 14.8 ), it allows for significant reductions in heating and cooling costs, while maintaining a stable temperature in homes or businesses.

For a homeowner in Montreal, Laval, Longueuil, the North Shore or the South Shore , this model often represents an excellent compromise between performance, electricity consumption, acoustic comfort and longevity.

Performance, comfort and savings: what the ORION XLTH changes every day

A capacity adapted to open-plan spaces

With 15,000 BTUs in cooling and approximately 18,000 BTUs in heating , this wall-mounted heat pump is particularly suitable for:

• to a large open-plan living room with kitchen and dining area;

• to a full floor of a duplex or a well-insulated cottage;

• to a small or medium-sized commercial space.

During our site visits, we consider the square footage, ceiling height, orientation, insulation quality, number of windows, and glazing type to confirm that a 15,000 BTU capacity is appropriate. The goal is to select a unit that is neither oversized (resulting in short cycles, discomfort, and premature wear) nor undersized (leading to insufficient heat in very cold weather or continuous operation at full power).

A true primary heating solution down to -26°C

The Orion XLTH range was developed specifically for northern regions. Where some wall-mounted heat pumps stop heating efficiently at -15°C, the ORION XLTH continues to provide a very good heating capacity down to -26°C .

In practice, this means that in a well-insulated duplex in Ahuntsic or Villeray, this heat pump can provide most of the heating for the upper floor. The furnace or electric baseboard heaters become a supplement, rather than the primary source. Several of our clients have confirmed that, even on the coldest January nights, the house remains comfortable without having to constantly adjust the thermostats.

Intelligent modulation and stable comfort

The inverter compressor in this heat pump continuously modulates its power. Instead of constantly starting and stopping at full capacity (as older on/off systems do), the ORION XLTH adapts its operation:

• it starts stronger to reach the target temperature;

• then it reduces its power to maintain this temperature with very limited variations;

• This avoids the sensation of excessively cold drafts or excessive heat.

In a condo in Montreal or in a house in Longueuil, this modulation results in very stable comfort , more homogeneous ambient air, less blowing noise and reduced electricity consumption.

Visible energy savings on the bill

With SEER2 values ​​of 27.5 (air conditioning) and HSPF2 values ​​of 12.7 (heating), this heat pump is among the most efficient models currently available for the Quebec residential market.

For a client who is replacing:

• an old, low-efficiency wall-mounted heat pump; or

• an electric baseboard heating system used as the primary means of heating,

It is not uncommon to see 20 to 35% annual savings on the overall electricity bill, sometimes more depending on the usage profile.

A concrete example:

• In Blainville , a family replaced their old heat pump with a FUJITSU ORION XLTH 15,000 BTU. Their well-insulated home was previously heated primarily by baseboard heaters. After a full heating season, their electricity bills decreased significantly, while they also enjoyed greater comfort and less temperature variation between rooms.

A responsible choice: R-32 refrigerant and sustainable design

R-32: more modern, more efficient

This heat pump uses R-32 refrigerant , which offers several concrete advantages:

• better energy efficiency for a smaller quantity of fluid;

• reduced environmental impact compared to older refrigerants;

• possibility of achieving high yields with more compact units.

For an owner, this means a machine designed for the future, compliant with new environmental requirements, and easier to optimize during maintenance.

Robust heat exchangers and quality components

The components of the FUJITSU ORION XLTH are designed to last:

• high-quality copper heat exchangers ;

• balanced indoor and outdoor fans to limit vibrations;

• Protected electronics for better resistance to voltage variations and harsh conditions.

In an environment like Greater Montreal, where equipment undergoes repeated freeze-thaw cycles, these robust features have a direct impact on system longevity. A well-installed and well-maintained machine can easily exceed 15 years of service.

Acoustic comfort: a heat pump that knows how to be unobtrusive

Noise is an increasingly important criterion for our clients, especially in urban areas or in condominiums.

Inside: a very low noise level

The FUJITSU ORION XLTH 15,000 BTU wall unit operates at a noise level as low as 26 dB(A) in quiet mode. At this level, the perceived noise is often lower than many ambient household noises (refrigerator, distant bathroom fan, low traffic).

For a bedroom open to a living area, a home office, or a living room where television is watched, this noise level is particularly appreciated. Several customers tell us that they sometimes forget the device is even on.

Outside: respect for neighbors and the noise environment

The outdoor unit remains within a range of approximately 49–50 dB(A). When installed correctly (on anti-vibration pads, with proper positioning and clearances respected), it remains discreet, even in a narrow alley or near a neighboring courtyard.

In Montreal, in densely populated neighborhoods like Plateau-Mont-Royal, Rosemont, or Verdun, we pay particular attention to orienting the unit to minimize noise reflection towards neighbors. Proper installation makes a big difference: stable support, correct leveling, and avoiding walls that are too close, which create a resonance effect.

Integrated Wi-Fi control and smart management

The FUJITSU ORION XLTH comes with built-in Wi-Fi . Once the connection is set up, you can:

• adjust the temperature of your home remotely;

• create schedules adapted to your routine (work, weekend, holidays);

• automatically reduce the temperature when you are away to save energy;

• Turn on the heating or air conditioning before you return so you arrive in a space that's already comfortable.

For customers with multiple units or a mixed-use building (residential + offices), this type of control optimizes overall consumption and better distributes heating or air conditioning demand according to the time of day.

In some more advanced projects (shops, offices, small buildings), this model can also be integrated into a centralized management system via specialized interfaces. This allows the control of several units to be consolidated onto a single panel or application.

An AirGreen installation designed to maximize performance

A heat pump of this caliber deserves meticulous installation. At AirGreen, we have established internal standards that we consistently apply.

Precise sizing and honest advice

During the estimation:

• We assess the area to be served , the configuration of the rooms, the ceiling height;

• we take into account existing elements: furnace, baseboards, electrical panels, available capacity;

• We analyze the habits of the occupants (daytime presence, work outside, children, teleworking).

If the FUJITSU ORION XLTH 15,000 BTU is not suitable for your situation (too large a surface, specific needs, atypical configuration), we will tell you clearly and suggest another model or another zone configuration.

Refrigerant piping: adjusted and documented charge

This heat pump operates on R-32 , and the amount of refrigerant must be perfectly adjusted to the actual length of the pipes.

Our standard procedure:

• accurately measure the length of the supply and return piping (liquid and gas);

• compare with the factory preload;

• add the exact additional quantity of refrigerant, respecting the technical recommendations;

• Note the total charge on a label or sheet given to the customer.

An incorrect charge can lead to reduced efficiency , premature compressor wear, suboptimal defrost cycles, and higher energy consumption. Therefore, we monitor this aspect very carefully.

Drain management and frost protection

The condensate drain on the indoor unit is often overlooked in poorly installed systems. At AirGreen, we:

• always ensure a proper slope for water drainage;

• Let's install clean and discreet cable trays for exposed conduits;

• use a quality condensate pump when the configuration requires it;

• We will add, if necessary, an anti-freeze tracing to prevent the drain from freezing in exposed sections.

This prevents leaks on walls, stained ceilings and water damage, especially in condos and apartments located above other units.

Outdoor unit: stability, clearance and efficient defrosting

For the outdoor unit:

• We install the heat pump on a stable, elevated base that is suitable for the weight of the machine;

• We use anti-vibration mounts to limit the transfer of vibration to the structure;

• We maintain sufficient clearance around the device to ensure good airflow and effective defrosting;

• We direct the unit to avoid areas where excessive snow is deposited (overflowing roofs, snowblower accumulations, etc.).

In winter, these details allow for better frost management on the outdoor heat exchanger, faster defrost cycles and a reduction in the risk of ice blockage.

Concrete examples of projects completed with the ORION XLTH 15,000 BTU

Ahuntsic – Family Duplex

A family in Ahuntsic owned an old, low-efficiency wall-mounted heat pump that had been installed for over 10 years. The unit was still working, but:

• the noise had become significant;

• heating performance at −20 °C was insufficient;

• Heating bills remained high.

We recommended the FUJITSU ORION XLTH 15,000 BTU as a complete replacement for the old unit. After one heating season:

• the temperature on the floor remained stable at around 21°C, even during periods of extreme cold;

• overall electricity consumption has decreased significantly;

• The indoor noise level has been greatly reduced.

Boucherville – New condo with space constraints

In a new condo in Boucherville, space for the outdoor unit was very limited, located in a shared technical area. The challenge: to integrate a high-performance heat pump without disturbing the neighbors, while respecting the condominium rules.

We opted for the FUJITSU ORION XLTH 15K :

• optimized piping layout to limit length and losses;

• outdoor unit installed on anti-vibration bases, orientation adjusted to reduce sound reflection;

• Complete Wi-Fi configuration to allow the owner to manage their comfort remotely.

The result: a comfortable condo year-round, without excessive noise in the common areas.

Blainville – Single-family home in front

A homeowner in Blainville wanted to install a heat pump on the front of his house, the only area that was actually available. His main concern was the noise for him and his immediate neighbors.

We installed the FUJITSU ORION XLTH 15,000 BTU with:

• precise positioning to avoid blowing directly towards the street;

• high-quality anti-vibration mounts;

• a discreet deflector to direct the airflow.

After installation, the customer confirmed that they could hardly hear the unit in the house, even when the machine was running at full power.

Recommended maintenance and pitfalls to avoid

A heat pump in this range can offer remarkable longevity, provided that a few good practices are followed.

Basic maintenance by the owner

• Indoor unit filters : clean every 2 to 3 months (vacuum cleaner or warm water, let dry thoroughly before putting back in place);

• Clearance of the outdoor unit : regularly check that snow, ice, leaves or debris are not blocking the heat exchanger;

• Visual monitoring : ensure that no excessive vibration, abnormal noise or water leakage occurs.

Periodic professional interview

We recommend annual maintenance by an AirGreen technician, including in particular:

• control of pressures, temperatures and performance;

• inspection of electrical connections;

• checking the condition of the coils and fans;

• adjustment or recommendation in case of the start of fouling or a drop in performance.

This monitoring helps to anticipate problems, extend the life of the device and maintain high performance.

Common mistakes that we often correct

When we work on installations carried out without the same level of rigor, we frequently find:

• approximate refrigerant charges (without precise measurement);

• condensate drains installed without sufficient slope;

• wall mounts without vibration dampers;

• outdoor units installed too low in a snow accumulation zone.

On a FUJITSU ORION XLTH, these errors can significantly reduce the camera's potential. That's why we insist on a thorough and careful installation from the outset.
