A wall-mounted heat pump designed for the Greater Montreal climate
At AirGreen , we install wall-mounted heat pumps every day in Montreal, Laval, Longueuil, and on both the North and South Shores . Over the years, we've seen a multitude of models, brands, and technologies. The FUJITSU ALTAIR 500 KPAS R-32 | 18,000 BTU is one of those units that stands out as a very logical choice for homeowners who want to combine comfort, energy savings, and reliability .
This heat pump belongs to the Altair series, developed to provide stable heating down to -15°C and, on this 18,000 BTU model, a specific mode allowing the operating range to be extended down to -20°C under good installation conditions. In cooling mode, its 18,000 BTU capacity is ideal for:
-
A full floor of an open-concept house ;
-
A large condo with combined living room, kitchen and dining room;
-
A typical Montreal plex apartment where a single appliance serves multiple rooms.
It was designed to withstand harsh Quebec winters and heavy, humid summers , while maintaining controlled electricity consumption.
A complete HVAC solution: power, efficiency, quiet operation and durability
Quantifiable and concrete performance figures
The FUJITSU ALTAIR 500 18,000 BTU is not just a "comfortable" device, it is also a product whose technical specifications speak for themselves:
-
Nominal cooling capacity: 18,000 BTU/h
-
Nominal heating capacity: 18,000 BTU/h
-
Power modulation allowing it to go down to about 4,000 BTU/h in low demand and up to about 24,000 BTU/h in peak heating;
-
SEER2 of 22.0 : very high seasonal efficiency index in air conditioning;
-
HSPF2 of 8.3 (cold region) : interesting efficiency for heating in a climate like that of Quebec;
-
EER2 of 12.5 : instantaneous efficiency in air conditioning;
-
COP up to 4.20 : for 1 kW of electricity consumed, the heat pump provides up to 4.2 kW of heat.
For a homeowner accustomed to electric baseboard heaters , this means that a heat pump can provide the same amount of heat while using significantly less electricity . Over a full heating season, the savings can be substantial, especially in homes where heating is used for several hours a day from November to March.
In practice, we often find that customers reduce their consumption by 25 to 40% for the area served by the device, while gaining in comfort (less temperature variation, better air circulation, better humidity management).
Discreet acoustic comfort, suitable for living spaces
Noise levels matter a great deal, particularly in small townhouses and condos:
-
Inside, the FUJITSU ALTAIR 500 18,000 BTU can go down to about 26 dB(A) in quiet mode, which is close to a simple, discreet background noise.
-
Even at higher fan speeds, the noise profile remains controlled, allowing you to watch TV, work remotely, sleep or chat without being disturbed by aggressive fan noises.
We often see this difference in typical configurations:
-
Condo in Montreal : unit installed in the living room, a few meters from the home office area. The client can participate in video conferences without having to turn off the heat pump.
-
Suburban house in Laval : unit placed in the open stairwell; even at night, in light heating mode, the noise level remains very accommodating to sleep.
Outdoors, the noise level generally remains around 50 dB(A) during normal operation. This is a valuable feature in narrow backyards , alleyways , and shared terraces , where neighbors are close and respect for the neighborhood is important.
A more responsible refrigerant choice: R-32
The FUJITSU ALTAIR 500 uses R-32 refrigerant, which has several advantages over the older R-410A:
-
Global warming potential (GWP) significantly lower , which reduces the environmental impact;
-
Less fluid is needed to achieve the same performance;
-
Excellent combination of energy efficiency and reduction of greenhouse gas emissions related to the system.
For a family looking to upgrade their heating and air conditioning system without compromising their environmental values, this feature is a major advantage. It's not just about comfort, but also about making a more sustainable choice in the long run.
An indoor unit designed to last: ProCore™, Hydro Fin and precise control
The indoor unit of the FUJITSU ALTAIR 500 is compact, elegant, and above all, technically well-designed to withstand the test of time:
-
ProCore™ copper coils : better resistance to corrosion and fouling. This is a real advantage in more demanding environments (proximity to roads, dust, pets, etc.).
-
Hydro Fin treatment on the heat exchanger: helps protect surfaces against corrosion and improves condensation drainage, which helps maintain performance over time.
-
Backlit remote control : convenient in the evening or in less bright rooms, with clearly identified functions.
-
Specialized modes:
-
Economy mode , to limit consumption;
-
Minimum heat mode , ideal for second homes or rarely used rooms;
-
Intensive (powerful) mode when you want to quickly raise the temperature;
-
Automatic restart in case of power failure;
-
Automatic defrosting , essential in cold climates.
-
During our maintenance visits, our technicians clearly see the difference between a basic device and a device like the Altair 500: the internal design, the quality of the materials and the ease of cleaning contribute to extending the lifespan and maintaining stable performance.
Compact outdoor unit, inverter compressor and high installation flexibility
The Altair 500's outdoor unit is equipped with an inverter compressor that modulates its power according to the home's needs. The unit doesn't simply run at full power and then shut off; it constantly adjusts its speed, which allows for:
-
More stable comfort , without sudden temperature variations;
-
Improved energy efficiency , since frequent, and always more energy-intensive, starts are avoided;
-
Reduced mechanical wear , which contributes to the longevity of the compressor.
For installation, the permitted pipe length is generous (up to approximately 30 meters , with a vertical drop of up to 25 meters , within the recommended limits). This gives us considerable freedom in positioning the outdoor unit:
-
On an inconspicuous back wall of a terraced house;
-
On a flat roof in some buildings;
-
On a floor support away from passageways, with anti-vibration cushions.
Standard 1/4" - 1/2" piping is the common practice for our teams. When combined with proper installation, good vacuuming, correct sizing, and an appropriate refrigerant charge, you get a high-performing, quiet, and durable system.
Connectivity and home automation integration
For owners who want to go further, the FUJITSU ALTAIR 500 can be equipped with:
-
A USB Wi-Fi module allows the device to be controlled via a mobile application: temperature adjustment, scheduling, switching between modes, etc.;
-
With interfaces adapted for integration into more advanced control systems (small commercial buildings, buildings, offices);
-
Dry contacts for certain specific integrations (alarm system, ventilation requests, auxiliary heating, etc.).
At AirGreen, we regularly use these possibilities in:
-
Professional offices that want to manage air conditioning according to occupancy hours;
-
Rental properties where the owner wants to maintain some remote control;
-
High-end residences where the heat pump is integrated into a larger home automation ecosystem.

Case study: a typical project in Longueuil
In Longueuil , we recently assisted a family living in a two-story cottage. Their old 12,000 BTU unit was no longer adequate, neither in summer nor winter. We recommended the FUJITSU ALTAIR 500 18,000 BTU for the following reasons:
-
Need to cover an open-plan ground floor and a floor partially open to the staircase;
-
Need for a device capable of heating efficiently at -15°C ;
-
The desire was to limit the noise, as the master bedroom was located near the stairwell.
The installation proceeded as follows:
-
Indoor unit installed on a central wall, directed towards the staircase, in order to promote air circulation towards the bedrooms;
-
Outdoor unit mounted on a cushioned wall bracket at the rear of the house, away from passageways, respecting the necessary clearances;
-
Piping of approximately 20 meters with a drop of 8 meters, perfectly within the range specified by Fujitsu.
After a first full winter, the owners observed:
-
A significant reduction in their electricity bill related to heating for the covered area;
-
A more uniform temperature , without cold spots near the stairs;
-
The external noise level was considered very acceptable, even in the evening.
AirGreen professional installation: the key to getting the most out of your Altair 500
Even an excellent device can lose its potential if it is incorrectly sized or installed. This is where AirGreen 's expertise comes in.
Study and dimensioning
Before any installation, we:
-
Let's check the surface area , the room layout, and the ceiling height;
-
Let's take into account the orientation of the house , the quality of the windows and the insulation;
-
Let's confirm that 18,000 BTU is the appropriate power, or recommend another model if necessary.
The objective is simple: to avoid both undersized (device that struggles to keep up) and oversized (device that too often operates at very low load, with less comfort and efficiency).
Technical installation and commissioning
Our refrigeration technicians:
-
They route the copper pipes carefully, controlling the slope of the drain and avoiding excessive bends;
-
They use rigorous vacuum pulling and leak testing methods;
-
Configure the basic settings (minimum temperature, recommended modes, shutter orientation, etc.);
-
They check that the defrosting is working properly and that the appliance is modulating its heating output.
This rigor allows the FUJITSU ALTAIR 500 heat pump to achieve the advertised performance, and not just theoretical performance.
Customer training and support
Once the installation is complete, we take the time to:
-
Explain how each mode works (heating, air conditioning, dehumidification, fan only);
-
Provide usage tips to optimize consumption (set temperature, humidity management, programming);
-
Present good HVAC maintenance practices (cleaning filters, clearing around the outdoor unit, etc.);
-
If desired, propose an annual maintenance plan to keep the system in good condition.
