Power, performance and durability serving Quebec comfort
At AirGreen, we understand better than anyone the challenges of Quebec winters: extreme temperatures, icy winds and a constant need for thermal comfort and energy efficiency. To meet these demands, we chose to recommend and install the CANAIR 4CDH R-454B Electric Furnace | 5 Tons, an exceptionally reliable central HVAC system designed to deliver consistent performance, quiet operation and energy efficiency among the best in its class.
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-airflow ECM motor and eco-friendly R-454B refrigerant make it the perfect solution for homes in Greater Montreal, whether for new construction 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 deliver top efficiency in both heating and cooling. Thanks to its inverter technology and adaptive capability, it continuously adjusts its power to the ambient temperature and the energy demand of your home. This keeps the temperature stable while reducing electricity use and extending compressor life.
With a SEER2 of 16.0, an HSPF2 of 9.0 and an EER2 of 10.0, this furnace is among the efficient models on the market. Above all, it is ENERGY STAR cold climate certified, with operation down to -30°C.
Its side-discharge system gives it great flexibility: unlike bulkier top-discharge models, the CANAIR 4CDH installs easily in tight spaces, narrow backyards or even on a rooftop terrace. A significant advantage for urban homes in Montreal, Laval or Longueuil.

A design built 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 (up, down, left or right) depending on the duct layout, allowing seamless integration into all types of homes, whether new, older or multi-story.
Constant-airflow ECM motor: comfort and efficiency
The furnace’s ECM motor ensures stable, consistent airflow, even when filters get dirty or duct pressure varies. This intelligent motor automatically adjusts its speed to deliver the right amount of air, reducing energy losses and improving indoor comfort. You enjoy balanced, quiet heating and cooling with no temperature swings.
Simplified maintenance
Every component of the CANAIR 4CDH has been designed to make maintenance easier and extend system life:
Slide-out evaporator coil for quick cleaning.
Front-access control panels for inspections.
Removable filters that are easy to maintain.
Grouped electrical components for simpler diagnosis.
These technical details significantly reduce maintenance time and minimize service interruptions, giving the owner complete peace of mind.
Quiet, 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 swings while keeping the indoor temperature constant. The result: optimal acoustic comfort, with indoor sound levels as low as 34.5 dB(A) — a real plus for those who value quiet.
Efficiency at very low temperatures
Even on the coldest days of the Quebec winter, the CANAIR 4CDH R-454B keeps heating. According to the NEEP data for this system (AHRI 215449709), it delivers 45,000 BTU/h at -8°C (COP 2.4) and up to 52,000 BTU/h at -15°C (COP 1.8). At -30°C, its maximum capacity is 30,900 BTU/h (COP 1.46).
This consistency makes all the difference in homes exposed to cold winds and extreme temperatures. You get 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, compared with 2,088 for the older R-410A. This makes the CANAIR 4CDH a unit aligned with Quebec’s environmental policies and international sustainability standards.
By choosing this system, you actively help reduce greenhouse gas emissions while enjoying exemplary energy efficiency.
Smart comfort and built-in safety
Intuitive Wi-Fi control
The included wired Wi-Fi controller lets you manage all of the unit’s functions, from temperature and operating mode to fan speed. This smart connectivity lets you adjust your comfort remotely and optimize your energy use effortlessly.
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 lets the system resume normal operation with the same settings, without manual intervention.
Anti-freeze and automatic defrost
The coils are protected by an automatic defrost system that prevents ice buildup and maintains heating performance even in humid, cold conditions. This avoids efficiency losses and extends compressor life.
An exemplary warranty
The basic 10-year warranty covers the compressor and all major parts, and labor is covered for 6 years, straight from the distributor. For complete peace of mind, an extended 10-year labor warranty is also available. This level of coverage reflects CANAIR’s confidence in the durability and reliability of its products.
