The perfect combination of power, efficiency and peace of mind

At AirGreen , we believe that a central heating and cooling system shouldn't just regulate a home's temperature: it should transform daily comfort. The CANAIR 4CDH Central Heat Pump - R454B | 3 Tons is much more than a device—it's a complete smart comfort solution adapted to the climatic realities of Quebec.
Designed, engineered and distributed to deliver maximum performance down to -30°C , this heat pump combines cutting-edge technology , compact design and unmatched energy efficiency . Whether for new construction or replacing an existing system, it represents a sustainable, efficient and eco-responsible investment.

A unique side discharge design on the Quebec market

The CANAIR 4CDH stands out firstly for its side discharge design , a major asset for owners looking for a system that is compact, quiet and adaptable . Unlike traditional top discharge units, this intelligent design allows for flexible installation in a variety of spaces:

• narrow backyards ,

• rooftop terraces ,

• restricted spaces between two walls ,

• or any other residential environment where space is limited.

This format also simplifies transport and handling : our technicians can easily move and install the unit on a base, often with two or even one person, without heavy equipment.
This increased maneuverability translates directly into faster, cleaner, and more cost-effective installation —a feature that reflects the AirGreen philosophy of professional, accessible, and hassle-free solutions.

Quiet, yet powerful: Inverter technology at your service

One of the most appreciated aspects of the CANAIR 4CDH Central Heat Pump is its exceptionally quiet operation .
Thanks to Inverter technology , the compressor continuously adjusts power according to the actual needs of your home, instead of operating in on/off cycles like traditional systems. This intelligent modulation reduces electricity consumption while maintaining a constant temperature and minimal noise levels :

• up to 25.5 dB(A) indoors (barely audible),

• approximately 62 dB(A) outside, the equivalent of a quiet conversation.

The result? A quiet and comfortable environment, day and night, without the temperature fluctuations or sudden noises typical of conventional systems.

Consistent performance, even below -30°C

Living in Quebec means facing harsh, often unpredictable winters. That's why the CANAIR 4CDH has been tested and certified to deliver consistent performance down to -30°C .
It retains 100% of its heating capacity at -20°C , with a COP (Coefficient of Performance) reaching 1.8 , which ensures stable energy efficiency even in the worst winter conditions.
This robustness makes the 4CDH an ideal choice for homeowners looking for a system capable of completely replacing their main heating source , while significantly reducing their annual energy bill.

Additionally, its constant airflow ECM continuously measures system pressure (coils, filters, ducts, etc.) and automatically adjusts fan speed to maintain optimal airflow . This results in:

• maximum energy efficiency,

• better indoor air quality,

• and extended device life.

ENERGY STAR® certified energy efficiency

With a SEER2 of 17.3 , a HSPF2 of 10.3 and an EER2 of 11.7 , the CANAIR 4CDH exceeds the most stringent North American energy efficiency requirements.
These performances have earned it ENERGY STAR® and Cold Climate V6.1 certifications, guaranteeing substantial energy savings and a significant reduction in the environmental footprint.

In concrete terms, this means that you benefit from higher efficiency with each use, summer and winter, with energy consumption up to 40% lower than that of older central heat pump models.
It is an investment that pays off year after year, especially in areas where electricity costs are controlled, such as in Quebec.

R-454B refrigerant: a new era of eco-responsibility

R-454B refrigerant represents a major advancement in the field of HVAC.
A progressive replacement for R-410A, it offers a global warming potential (GWP) of only 466 , 65% lower than that of previous fluids.
It is an A2L type refrigerant , recognized for its stability, efficiency and safety.

By opting for the CANAIR 4CDH , you are actively contributing to reducing greenhouse gas emissions while benefiting from a more efficient, more ecological heat pump that complies with the most demanding environmental standards on the market.

An ingeniously designed indoor unit

The 4CDH2036F21 indoor unit stands out for its highly modular and easy-to-maintain design.
It offers installation versatility (vertical or horizontal configuration, top, bottom, left or right airflow), making it ideal for a wide variety of residences.

Main features:

• Constant flow ECM motor up to 0.8 in H₂O, ensuring stable pressure and uniform comfort.

• Sliding aluminum evaporator coil for easy cleaning and maintenance.

• Quick access panels for inspection and replacement of components.

• Electric heating elements available from 5 to 25 kW, depending on the building's needs.
