Nordic efficiency by CANAIR: the heat pump designed for Quebec

At AirGreen, we believe that a heating, ventilation, and air conditioning (HVAC) system must, above all, be a sustainable, intelligent solution adapted to the reality of our Quebec winters. This is exactly what the CANAIR 4C28 - R454B | 3-Zone - 27,000 BTU Outdoor heat pump represents: a model of performance and reliability, designed to offer consistent comfort, remarkable energy efficiency, and absolute peace of mind, season after season.
The result of decades of expertise in the field of heating and air conditioning, this heat pump is part of the 4C28 series , a preferred choice for Quebec households seeking a perfect balance between technology, design and energy efficiency.

A flexible and intelligent multi-zone solution

The CANAIR 4C28 - R454B 3-Zone is designed to offer exceptional flexibility. Its outdoor unit can power up to three separate indoor units, allowing precise temperature control in different areas of your home.
Do you want a living room at 21°C, a slightly cooler bedroom at 19°C, and a perfectly tempered office at 22°C? Nothing could be simpler: each zone is independent, ensuring personalized comfort and substantial energy savings.

This modularity makes it an ideal solution for:

• Multi-story houses where the distribution of heat or coolness is often uneven;

• Condos and multi-family dwellings requiring separate thermal management per room;

• Offices or small businesses seeking constant comfort without energy waste.

With the “Follow Me” function , the remote control becomes a true mobile sensor: the device automatically adjusts its performance based on the actual temperature in your location. You no longer need to compensate for heat variations from one room to another—the heat pump takes care of it for you.

Impressive performance, even in extreme conditions

The CANAIR 4C28 stands out for its robustness and its ability to provide stable performance down to -30°C . Unlike many conventional heat pumps that lose their efficiency in extreme cold, this one maintains constant power, ensuring your comfort even during periods of intense frost.

Its technical characteristics testify to this:

• Heating capacity: 27,000 BTU

• Cooling capacity: 27,000 BTU

• SEER2 Energy Efficiency: Up to 23.0

• HSPF2: 10.5

• EER2: 12.5

• Guaranteed operation down to -30°C in heating and +50°C in air conditioning

• Exterior noise level: barely 61 dB(A)

This combination of power and stability makes the CANAIR 4C28 an ideal solution for regions subject to marked climatic variations — whether Montreal, Laval, Longueuil or the windier areas of the North Shore and South Shore.

Inverter technology: performance and energy precision

The heart of the CANAIR 4C28 is Inverter technology , a major innovation that adjusts the compressor speed in real time according to the exact needs of your home.
Rather than constantly switching on and off (like older traditional systems), the Inverter modulates power to maintain a stable and comfortable temperature while reducing energy consumption.

Its advantages are multiple:

• Significant energy savings : the heat pump consumes up to 30% less electricity than a conventional system.

• Constant comfort : no more unpleasant temperature fluctuations, the feeling remains stable.

• Increased durability : reduced wear of components, extending the life of the system.

• Exceptional silence : the inverter motor operates smoothly, without sudden noises or vibrations.

It is this cutting-edge technology that allows the CANAIR 4C28 to deliver maximum performance while minimizing its environmental footprint—a rare and sought-after combination.

A system designed for the Quebec climate

Every detail of the CANAIR 4C28 has been designed to withstand Nordic conditions. Its integrated heating cable system around the compressor and at the base of the outdoor unit prevents ice formation, ensuring smooth operation even during winter storms.
Automatic restart after a power outage ensures continuous heating without manual intervention. And with the cold air draft prevention function , you will never experience that unpleasant feeling of cold air when the heater starts.

The unit is also equipped with:

• TU1 copper coil : material highly resistant to corrosion and pressure.

• Integrated multifunction board : intelligent energy management to avoid overconsumption.

• Turbo mode : rapid temperature rise or accelerated cooling depending on the season.

• Silent Mode : Ideal for nighttime or relaxing moments.

• Self-cleaning function : eliminates humidity and prevents the formation of mold in the exchangers.

In short, everything has been designed to offer absolute comfort, without compromising on durability.

R-454B refrigerant: a major ecological breakthrough

One of the elements that distinguishes the CANAIR 4C28 series is the use of R-454B refrigerant gas , a new generation refrigerant that advantageously replaces R-410A.
This gas, classified A2L , offers a global warming potential (GWP) approximately 75% lower than that of its predecessor, while maintaining excellent energy performance.
By choosing the CANAIR 4C28 , you are making an eco-responsible choice, contributing to the reduction of greenhouse gas emissions without compromising on comfort.

Additionally, the automatic refrigerant leak detection function protects your home and your appliance: if a leak is detected, the unit immediately stops operation and displays an error code, ensuring the safety of your environment.

Modern and intuitive connectivity

The CANAIR 4C28 can be equipped with a smart Wi-Fi module , allowing you to control the device remotely via a mobile app. You can adjust the temperature, activate Turbo mode or switch to silent mode before even getting home.
This is a feature particularly appreciated by our customers in Montreal and Laval who want to manage their comfort while they are away or optimize energy consumption when they are traveling.

Imagine: You leave work, launch your AirGreen app, and your home is already at the perfect temperature when you arrive.
