Mini Split FUJITSU ORION XLTH+ | 15,000 BTUs | Montreal, Laval, South Shore, North

The mini split system for extreme cold that truly reassures Quebec homeowners

At AirGreen , we have been installing the FUJITSU ORION XLTH+ 15,000 BTU Mini Split for several years in the greater Montreal area, Laval, Longueuil, the North Shore and the South Shore . This model from the Orion XLTH+ series is designed for the real-world conditions of Quebec: long, harsh winters, periods of milder weather, increasingly hot summers, buildings with varied configurations, and homeowners who want a reliable, quiet, and high-performing system for the long term.

This mini-split unit also stands out for its eligibility for the LogisVert provincial subsidy , with assistance of up to $1,296 (as of May 1, 2025) for eligible projects. Combined with an extended 12-year warranty on the compressor and 12 years on parts , this unit offers a high-end solution for those who want to make a sound, one-time investment in their comfort.

A mini-split system designed for Quebec's true climate

In Quebec, an HVAC system is not simply a comfort accessory: it is an essential element of safety and quality of life. The FUJITSU ORION XLTH+ 15,000 BTU was developed to maintain stable performance even under the most demanding conditions.

Reliable heating down to -30°C

The key feature of this model is its guaranteed heating capacity down to -30°C . This means that even when the temperature drops well below average, the system continues to provide consistent heat without shutting down or switching to safety mode.

In the context of Montreal, Laval, the North Shore and the South Shore , this addresses several realities:

• nights at -25°C to -30°C several times per winter;

• buildings that are sometimes old, with colder areas;

• the need to reduce reliance on electric baseboard heaters or heating oil.

The outdoor unit incorporates specialized features for cold climates (defrost management, base plate design, fan control), which helps limit ice formation and optimize defrost water drainage. In practice, this improves reliability during periods of milder weather followed by severe cold, a common occurrence in our winters.

Inverter technology: stable comfort, controlled energy consumption

The inverter compressor continuously adjusts its speed according to actual needs. Rather than operating on an "on or off" basis, the unit adjusts its power, which:

• limits temperature fluctuations;

• reduces frequent starts;

• improves overall efficiency;

• extends the lifespan of components.

Concrete results for the user:

• a gentler and more consistent feeling of warmth in winter;

• less aggressive and more uniform air conditioning in summer;

• more predictable electricity consumption, especially when replacing baseboards.

R-32 refrigerant: performance, efficiency and environmental responsibility

The FUJITSU ORION XLTH+ 15,000 BTU uses R-32 refrigerant , which is rapidly becoming the new standard in high-performance residential systems. This gas has a much lower global warming potential than older generations (such as R-410A), while offering excellent thermal conductivity.

For our clients, this translates to:

• better energy efficiency at equivalent power;

• a reduction in the environmental impact of the HVAC system;

• better preparation for future environmental standards.

For AirGreen, this choice is part of a comprehensive approach: offering systems that combine comfort, savings, and responsibility . During installation, our refrigeration technicians handle the vacuuming, refrigerant charging, leak testing, and all the necessary steps to ensure that the R-32 operates under optimal conditions.

Four-season comfort: high-level air conditioning and heating

The 15,000 BTU model is particularly versatile. It can be used for:

• main system in a well-insulated, medium-sized dwelling;

• an ideal solution for an open-plan living-kitchen-dining room;

• comfort system for a widely used home office ;

• targeted air conditioning and heating for a two-level condo .

Air conditioning performance

In summer, the FUJITSU ORION XLTH+ 15,000 BTU offers a cooling capacity of 15,000 BTU , with air distribution designed to prevent hot or cold spots. Motorized louvers and various airflow modes allow you to direct air either directly towards the room or towards the ceiling for a more even air mixture.

Its SEER2 rating of 28.7 places it in a very high efficiency category. In practice, this means that a significant portion of the electricity consumed is actually converted into comfort, rather than being wasted. Over several seasons, this can represent a noticeable difference on bills, especially when replacing an old wall-mounted air conditioner or an energy-inefficient window unit.

Heating performance

In heating mode, the HSPF2 13.0 demonstrates excellent seasonal efficiency. The system continues to provide stable heat even in very cold weather, reducing the need for backup electric baseboard heaters.

In practice, many of our clients choose to:

• program a comfortable temperature setting (21–22 °C) continuously;

• leave the baseboards in place for protection, with a slightly lower setting;

• enjoy a more pleasant feeling of comfort thanks to the gentle air circulation.

Quiet operation and discreet wall-mounted design

Another strong point of the FUJITSU ORION XLTH+ 15,000 BTU : its extremely quiet operation.

Very quiet indoor unit

The indoor unit operates at a noise level as low as 26 dB(A) in its quietest modes. At this level, the noise is below the threshold for many everyday activities (such as whispering or gentle ventilation). Even at higher speeds, the noise remains controlled, allowing for comfortable use in:

• a master bedroom ;

• a home office where video calls are frequent;

• a living room where television, music or conversations must remain clearly audible.

Discreet outdoor unit

With a noise level of 51 dB(A) during operation , the outdoor unit is discreet in a backyard, on a balcony, or near a driveway. This is an important consideration for homeowners who share outdoor spaces with neighbors (duplexes, triplexes, condominiums).

The compact design of the outdoor unit and the pipe lengths of up to approximately 20 meters offer great flexibility for positioning it in a strategic location: less wind, less perceived noise, better accessibility for maintenance.

Built-in Wi-Fi and smart control of your comfort

The FUJITSU ORION XLTH+ includes standard Wi-Fi functionality , allowing remote control via a mobile application.

On a daily basis, our customers use this connectivity to:

• turn on the heating before going home in very cold weather;

• slightly reduce the instruction when they are absent for a few hours or for the day;

• quickly check the condition of the house while travelling;

• adjust the mode (heating, air conditioning, dehumidification, ventilation) without moving.

For owner-occupiers, those managing multiple properties, or professionals working remotely, the ability to manage their HVAC system from their phone quickly becomes essential.

Examples of AirGreen installations with the FUJITSU ORION XLTH+

Over the years, we have applied this model in a wide variety of contexts. Here are some typical scenarios that illustrate its versatility.

Laval – Two-story house with open concept

A family wanted to replace an old wall-mounted air conditioner and reduce their reliance on electric baseboard heaters. We installed the FUJITSU ORION XLTH+ 15,000 BTU in the open-concept main floor area (living room, dining room, kitchen).

Results observed after the first season:

• more stable temperature throughout the living area;

• significant reduction in electricity consumption for heating;

• significant reduction in perceived noise compared to the old system.

South Shore – Windy Corner Condo

On the South Shore , in a condo on the top floor of a building, the owner complained of cold rooms in winter and excessive heat in summer, especially on the side facing the prevailing wind. The installation of an Orion XLTH+ 15,000 BTU heater resolved the issue.

• a better temperature balance between the rooms;

• reliable operation during nights at -25°C and below;

• a significant reduction in the sensation of cold drafts.

Montreal – Renovated duplex with home office

In Montreal, a couple working from home needed a system:

• silent;

• effective;

• capable of ensuring stable comfort in an open space including an office.

The FUJITSU ORION XLTH+ was chosen for its quiet operation, inverter technology, and heating capability in extreme cold. Today, this system allows the couple to work comfortably, even during periods of extreme cold, without any distracting background noise during online meetings.
