The new benchmark for multi-zone comfort in Quebec

At AirGreen , we believe that an HVAC system isn't just about heating or cooling a home—it's about creating a stable, healthy, and comfortable living environment , regardless of outdoor conditions. The CANAIR 4C28 - R454B | 3-Zone - 36,000 BTU Outdoor Heat Pump perfectly embodies this vision. Designed and manufactured for Quebec's climate, it combines power, durability, smart technology, and eco-performance , in a multi-zone configuration capable of adapting to every style of residence.

Cutting-edge inverter technology for constant comfort

The CANAIR 4C28 series is based on Inverter technology , a major innovation allowing precise control of the compressor according to the actual temperature demand. This dynamic approach allows the heat pump power to be adjusted instantly to maintain a stable temperature and reduce energy consumption to a strict minimum.

Concrete benefits for your comfort and your wallet:

• Significant energy savings : the heat pump consumes less electricity than a traditional system, because it never starts at full power unnecessarily.

• Stable and even temperature : no more sudden changes in heat or cold; the room maintains constant comfort throughout the day.

• Quiet operation : Thanks to its sophisticated mechanical design, the 4C28 is almost invisible, even when fully loaded.

• Increased durability : The inverter compressor undergoes fewer stop-start cycles, extending the life of the unit.

This combination of efficiency and precision makes the CANAIR 4C28 ideal for Quebec's harsh winters, capable of reaching -30°C without compromising performance.

A heat pump designed for the Quebec climate

Designed specifically for northern conditions, the CANAIR 4C28 excels where other systems falter. Its Cold Climate V6.1 certification ensures stable performance even in extreme cold, while its next-generation R-454B refrigerant significantly reduces environmental impact while maintaining exceptional heating capacity.

The 3-Zone – 36,000 BTU model was designed for family residences, modern duplexes, or commercial offices requiring uniform coverage across multiple floors. Each interior zone operates independently, allowing the temperature to be adjusted as needed:

• A living room that is always at the right temperature , whatever the season;

• Quiet and comfortable rooms at night ;

• A temperate basement even during the most intense cold spells.

This flexibility makes the 4C28 series a perfect solution for owners looking for balanced and intelligent comfort.

Multi-zone power: one unit, three perfectly balanced zones

With its 3-Zone – 36,000 BTU configuration, the CANAIR 4C28 offers rarely equaled power and modularity. The outdoor unit manages several indoor units autonomously, constantly adjusting the airflow and compressor power.

This multi-zone system ensures:

• Tailor-made comfort in every room, without loss of energy efficiency;

• Reduced heating costs thanks to optimized temperature regulation;

• Complete adaptability to everyday needs: bedroom, living room, office, basement or workshop.

With an efficiency of 23 SEER2 , an HSPF2 of 10.7 and a heating capacity maintained down to -30°C , this heat pump is among the most efficient in its category.

Features that make all the difference

1. Turbo Mode

Engage Turbo Mode to reach your desired temperature in record time, whether you want to cool down quickly after a hot day or warm up your home in the middle of winter.

2. Self-cleaning function

The system automatically cleans the indoor and outdoor coils , preventing the formation of mold and unpleasant odors. This process extends the life of the unit and maintains impeccable air quality.

3. “Follow Me” function

Thanks to a sensor integrated into the remote control, the temperature is regulated based on your actual position in the room — for targeted, intelligent comfort.

4. Prevention of cold draft

When starting in heating mode, the heat pump prevents unpleasant cold air from blowing in. You benefit from gentle, immediate heat as soon as it is switched on.

5. Optional WiFi control

Control your system remotely via your phone or tablet. Ideal for coming home to a warm house or adjusting settings while you're away.

6. Automatic restart

In the event of a power outage, the 4C28 automatically restarts with the previously saved settings—no adjustments required.

7. Integrated heating cables

These cables prevent ice from forming around the compressor and the base of the outdoor unit, ensuring stable performance even during the worst winter storms.

8. Ultra-quiet operation

With a noise level of only 65 dB(A) , the CANAIR 4C28 remains discreet, even when operating at full capacity. This quiet operation is particularly appreciated in residential areas and condominiums.
