Power, performance and durability serving Quebec comfort

At AirGreen , we understand better than anyone the challenges of Quebec winters: extreme temperatures, icy winds, and the constant need for thermal comfort and energy efficiency. To meet these demands, we chose to recommend and install the CANAIR 4CDH R-454B | 5 Ton Electric Furnace , an exceptionally reliable central HVAC system designed to deliver consistent performance, quiet operation, and best-in-class energy efficiency.

A true technological gem, the CANAIR 4CDH R-454B embodies the next generation of central heating and cooling systems. Its compact design, flexible installation, constant-flow ECM motor, and environmentally friendly R-454B refrigerant make it the perfect solution for homes in Greater Montreal, whether it's a new build or a complete renovation of your existing HVAC system.

A high-efficiency central system for all seasons

The CANAIR 4CDH system has been specially developed to offer cutting-edge efficiency in both heating and cooling. Thanks to its inverter technology and adaptive capability, it continuously adjusts its power according to the ambient temperature and energy demand of your home. This helps maintain a stable temperature while reducing electricity consumption and extending the compressor's lifespan.

With a SEER2 of 16.0 , an HSPF2 of 9.0 and an EER2 of 10.0 , this furnace is among the most efficient models on the market. And above all, it is ENERGY STAR COLD CLIMATE certified , which guarantees optimal performance even when the mercury drops below -30 °C.

Its side-discharge system gives it unparalleled flexibility: unlike top-discharge models, which are bulkier and noisier, the CANAIR 4CDH can be easily installed in tight spaces, narrow backyards, or even on a rooftop terrace. A significant advantage for urban residences in Montreal, Laval, or Longueuil.

Detailed technical specifications

A design thought for performance and simplicity

Fast, clean and versatile installation

One of the main advantages of the CANAIR 4CDH R-454B is its intelligent design and compact size . Thanks to its light weight and easy-to-remove access panels, a single technician can carry out the complete installation on site. The system can be configured in multiple positions (top, bottom, left or right) depending on the air duct layout, allowing for seamless integration into all types of residences, whether new, old or multi-story.

Constant flow ECM motor: comfort and efficiency guaranteed

The furnace's ECM motor ensures stable and consistent airflow, even if filters become dirty or duct pressure fluctuates. This intelligent motor automatically adjusts its speed to deliver the right amount of air, reducing energy loss and improving indoor comfort. You'll enjoy balanced, quiet heating and cooling with no temperature fluctuations.

Simplified maintenance

Each component of the CANAIR 4CDH has been designed to facilitate maintenance and extend the life of the system:

• Slide-out evaporator coil for quick cleaning.

• Accessible control panels at the front for inspections.

• Easy-to-maintain removable filters .

• Electrical components grouped together for simplified diagnosis.

These technical details significantly reduce maintenance time and minimize service interruptions, resulting in complete peace of mind for the owner.

Quiet and stable operation

Thanks to inverter technology , the compressor continuously adjusts its speed instead of switching on and off abruptly. This intelligent modulation reduces noise and energy fluctuations, while maintaining a constant indoor temperature. The result: optimal acoustic comfort, with indoor noise levels as low as 34.5 dB(A) —a real plus for those seeking peace and quiet.

Maximum efficiency at very low temperatures

Even on the coldest days of the Quebec winter, the CANAIR 4CDH R-454B continues to operate at full capacity. It can reach 100% of its heating power at -20°C , while maintaining a COP (coefficient of performance) of 1.8 , guaranteeing higher energy efficiency than many competing furnaces.

This consistency makes all the difference in homes exposed to cold winds and extreme temperatures. You benefit from constant, even, and energy-efficient heat, without excessive reliance on backup systems.

Environmentally friendly

R-454B refrigerant: an eco-responsible advance

R-454B is a new generation refrigerant, classified A2L , with a global warming potential (GWP) of 466 , almost 80% lower than that of older refrigerants such as R-410A. This technological choice makes the CANAIR 4CDH a device aligned with Quebec's environmental policies and international sustainability standards.

By opting for this system, you actively contribute to the reduction of greenhouse gas emissions while benefiting from exemplary energy efficiency.

Smart comfort and integrated security

Intuitive Wi-Fi control

The included Wi-Fi wired controller lets you control all of the unit's functions, from temperature and operating mode to fan speed. This smart connectivity lets you remotely adjust your comfort and effortlessly optimize your energy consumption.

Safety and automatic diagnosis

The system has a self-diagnostic mode that detects any abnormality (refrigerant leak, overheating, faulty sensor, etc.) and displays a clear error code. In the event of a power failure, the automatic restart function allows the system to resume normal operation with the same settings, without manual intervention.

Anti-freeze and automatic defrost function

The coils are protected by an automatic defrost system that prevents ice buildup and maintains heating performance even in humid and cold conditions. This prevents any loss of efficiency and extends the life of the compressor.

An exemplary guarantee

The basic 10-year warranty covers the compressor and all major parts. For complete peace of mind, an extended 10-year labor warranty is also available. This level of coverage demonstrates CANAIR's confidence in the durability and reliability of its products.
