FUJITSU ALTAIR 300 Mini Split | 12,000 BTU 115V: a wall-mounted heat pump designed for the electrical realities of Greater Montreal

In many homes, condos, plexes and small businesses in Greater Montreal, the question always arises when adding an air conditioning or heating system: how to improve comfort without completely rewiring the electrical system? The FUJITSU ALTAIR 300 Mini Split | 12,000 BTU 115V was specifically designed to address this type of situation.

This compact and quiet 115V wall-mounted mini split unit provides both air conditioning and heating in a single unit, while easily integrating with existing electrical panels. For homeowners in Montreal, Laval, Longueuil, and on the North and South Shores, it's an efficient way to add a high-performance wall-mounted heat pump without undertaking major and costly electrical work.

At AirGreen, we install this model in a multitude of configurations: bungalows, urban condos, triplexes, suburban homes, street-level commercial spaces, and professional offices. The ALTAIR 300 has established itself as a highly strategic choice for those who want a reliable system, well-sized for a main room or open area, with controlled energy consumption and a very low noise level .

A 115V mini split system that often eliminates the need for electrical panel upgrades

A 115V power supply that changes everything

One of the biggest advantages of this model is its 115V power supply . In many Greater Montreal buildings, the electrical panel is already heavily used: stove, dryer, water heater, oven, old wall-mounted air conditioner, etc. Adding a new 240V circuit often requires:

• the intervention of a master electrician to reconfigure the panel ;

• the replacement or enlargement of the main panel;

• significant additional costs and sometimes delays from Hydro-Québec or the building owner.

The ALTAIR 300 operates on 115V with a 14A MCA and a 20A MOP , which in many cases allows for the simple addition of a dedicated circuit without expanding the panel. For condos, apartments, or rented commercial spaces, this is often the key to making the project feasible without causing electrical issues.

A 12,000 BTU capacity suitable for living areas

With a nominal capacity of 12,000 BTU , this mini split system is perfectly sized for:

• an open main room of 450 to 650 sq ft (living room + kitchen + dining room);

• a commercial space such as a boutique, hair salon, professional office, small clinic;

• an entire floor in a duplex or triplex where one wishes to stabilize the comfort;

• an urban condo where the priority is a large open area.

The heater remains effective down to -15°C , making it an excellent solution for typical Montreal winters when temperatures hover around -10/-12°C, while also providing relief from electric baseboard heaters or older, less efficient systems. When the temperature drops below -15°C, the ALTAIR 300 can still contribute, but it will generally be used in conjunction with an existing supplemental heating system.

Inverter technology and energy efficiency

A modern wall-mounted heat pump

The FUJITSU ALTAIR 300 is equipped with Inverter technology , which means the compressor automatically adjusts its speed according to the actual heating or cooling demand. Unlike older systems that operate on an on/off basis, the Inverter allows for:

• to avoid unpleasant temperature variations;

• to reduce peak electricity consumption ;

• to increase the comfort and lifespan of the device (fewer sudden starts).

This mode of operation is particularly appreciated in rooms where a lot of time is spent: living room, bedroom, office, work area, customer area.

Consistent efficiency values ​​for everyday use

In cooling mode, the ALTAIR 300 offers a SEER2 of approximately 17.0 , placing this model in the category of efficient units without falling into the ultra-high-end, often much more expensive, ranges. In heating mode, it has an HSPF2 of approximately 9.0 (region IV) , suitable for the climate of southern Quebec for use as a wall-mounted heat pump primarily during the mid-seasons and down to -15°C.

The COP (coefficient of performance) for heating places the unit in a zone where, for every kilowatt consumed, it can deliver several kilowatts of heat. In practical terms, compared to traditional all-electric heating, substantial savings on energy bills can be observed, especially in rooms where the heat pump operates regularly.

R-32 refrigerant and reduced environmental impact

The ALTAIR 300 uses R-32 refrigerant , a newer technology than R-410A, which was long used as the standard. R-32 offers several advantages:

• a Global Warming Potential (GWP) significantly lower than R-410A;

• better overall energy efficiency with similar refrigerant volumes;

• an adaptation to regulatory guidelines aimed at reducing the impact of refrigerant gases.

For owners mindful of the environmental footprint of their equipment, choosing an R-32 appliance is a concrete step towards more responsible long-term installations.

Acoustic comfort and indoor air quality

An extremely low interior noise level

One of the major strengths of the FUJITSU ALTAIR 300 mini split unit is its low internal noise level of 20 dB(A) at the lowest fan speed. This figure is very significant:

• 20 dB(A) is an almost imperceptible noise , ideal for a bedroom or an office where you want to work in silence;

• Even at higher fan speeds, the noise level remains under control, allowing for pleasant use at all times.

In practice, our customers often tell us that they "forget" that the device is running, especially at night in silent mode.

Discreet outdoor unit for alleyways, balconies and courtyards

The outdoor unit is compactly sized, with a sound pressure level of approximately 48 dB(A) . This makes it particularly suitable for:

• condo balconies or terraces;

• the narrow backyards typical of Montreal plexes;

• the alleyways where several air conditioning units are grouped together.

The format and noise level limit the risks of nuisance to the neighborhood and facilitate approvals in co-ownership when these impose constraints on noise or the aesthetics of the installations.

Design, dimensions and integration into your spaces

Compact and understated indoor unit

The indoor unit of the ALTAIR 300 measures approximately 30.31 x 8.56 x 9.81 inches (W x D x H) . Using this template:

• It can be easily installed above a door, window or piece of furniture;

• It fits into modern settings as well as more classic interiors;

• Its clean lines avoid the "massive block" effect sometimes seen on older devices.

The discreet design allows the device to be placed in visible rooms (living room, dining room) without detracting from the decor.

Well-proportioned outdoor unit

The outdoor unit measures approximately 26.13 x 11.44 x 21.83 inches (W x D x H) . Its reasonable size makes it easy to:

• installation on a wall bracket, a base on the ground or a structure designed to clear the unit of snow;

• passage through narrow alleys or limited access;

• positioning according to condominium rules, window openings and property lines.

With 1/4 - 3/8 inch copper piping , the system is compatible with the installation standards that our refrigeration technicians use daily.

Connectivity, control and home automation

Wireless remote control included

The FUJITSU ALTAIR 300 mini split system comes standard with a complete and ergonomic wireless remote control . It allows you to:

• select the mode (heating, air conditioning, dehumidification, ventilation, Auto);

• adjust the temperature precisely;

• adjust the fan speed;

• use the timer and some advanced functions (saving, powerful mode, etc.).

This remote control is suitable for the vast majority of users, especially those who do not necessarily want to use an application.

WiFi options and smart integration

For customers who wish to control their device remotely, it is possible to add a compatible Wi-Fi module . Once installed and configured, the user can:

• turn on the air conditioning before returning home in the summer;

• adjust the heating setting remotely when returning later than expected;

• Check the system's operating status from a smartphone.

In many projects, our teams take the time during installation to connect the device to the home network and explain how the application works to the client or occupants.

Sustainability, ProCore™ and adaptation to the Quebec climate

ProCore™ coils and corrosion resistance

The indoor unit incorporates highly corrosion-resistant ProCore™ copper coils . In Quebec's climate, where the units are subjected to:

• high humidity;

• urban pollution;

• the repetitive cycles of freezing and thawing;

This feature is a real asset for the lifespan of the unit . A heat exchanger well protected against corrosion reduces the risk of refrigerant leaks and helps maintain performance over the years, especially when maintenance is carried out regularly.

Pipe lengths and placement flexibility

With a maximum pipe length of 20 m and a significant maximum elevation difference, this mini split system offers great flexibility:

• The indoor unit can be installed in the center of the area to be treated for greater comfort;

• the outdoor unit can be placed in a more discreet location (back yard, side of the house, flat roof, side balcony);

• This helps to comply with the architectural, aesthetic or regulatory constraints of certain sectors.

Examples of AirGreen installations in the field

Laval: open-concept living room and kitchen in a bungalow

In Laval, a couple with an open-concept living room and kitchen in a bungalow of approximately 550 sq ft wanted to replace a noisy and inefficient window air conditioner while adding a more economical heating solution than electric baseboard heaters. The ALTAIR 300 12,000 BTU 115V was chosen for:

• its capacity adapted to the surface area;

• its 115V power supply , avoiding the need to redo the panel;

• Its silent mode for evenings and nights.

After installation, customers noticed a significant decrease in the use of baseboards in the mid-season and a much more uniform temperature in the living area.

South Shore: cosmetics boutique in Boucherville

On the South Shore, a boutique owner wanted a discreet system, both visually and in terms of noise, so as not to negatively impact the customer experience. Since the premises were rented, rewiring the electrical panel was out of the question. The ALTAIR 300 115V emerged as the simplest solution.

• integration of the indoor unit at a height, in a less visible area;

• outdoor unit installed on an above-ground structure, sheltered from snow;

• silent operation allows for a calm atmosphere to be maintained at all times.

Montreal: condo on the Plateau-Mont-Royal

In a condo on the Plateau, the owner primarily wanted to improve the comfort of the master bedroom and a home office area, both in summer and winter. With the electrical panel already at its limit, the 115V option was crucial. Results:

• stable temperature in the room, even on very hot nights;

• reduction of the use of electric heating in this area during the winter;

• appreciable acoustic comfort, the device remaining very discreet in silent mode.

Maintenance, best practices and lifespan

To guarantee the performance and durability of your FUJITSU ALTAIR 300 mini split unit , a few simple steps are recommended:

• Clean the internal filters approximately once a month during periods of intensive use to maintain good airflow and prevent dust buildup.

• Check the outdoor unit at each change of season to ensure that no debris, leaves, ice or snow is blocking the fan or the air inlet and outlet ports.
