A new generation of comfort and performance from AirGreen

At AirGreen , we believe that a modern HVAC system shouldn't just heat or cool: it should create smart, energy-efficient, and sustainable comfort. The CANAIR 4CDH R-454B | 4-Ton Electric Furnace perfectly embodies this vision.

Designed to meet Quebec's climate requirements, this central furnace combines cutting-edge technology, proven reliability and respect for the environment , while remaining remarkably quiet and easy to maintain. Its compact and elegant design adapts equally well to single-family homes and multi-unit buildings, making it a solution of choice for residences in Montreal, Laval, Longueuil, the North Shore and the South Shore .

With over 48,000 BTUs of power, exceptional energy efficiency and perfect compatibility with modern central heat pumps , this furnace is a pillar of Quebec comfort.

Superior performance, even in extreme winter

Reliable heating down to –30°C

Thanks to its Inverter technology , the CANAIR 4CDH R-454B operates continuously, automatically adjusting its power to maintain a stable temperature, even during intense cold spells.
This system provides 100% heating capacity at –20°C and continues to operate efficiently down to –30°C , without any noticeable loss of performance.

This is a major step forward for homeowners in Quebec, where harsh winters require systems capable of uninterrupted performance. The result: consistent comfort, improved thermal stability, and a significant reduction in electricity consumption.

Exemplary energy efficiency

The CANAIR 4CDH R-454B | 4 Ton Electric Furnace is ENERGY STAR and Cold Climate V6.1 certified, two guarantees of superior performance.
With a SEER2 of 16.5 , an HSPF2 of 9.5 , and an EER2 of 10.5 , it ranks among the best in its class. These values ​​translate into reduced energy costs and a smaller carbon footprint, without compromising heating or cooling power.

A compact, flexible and intelligent design

Power in a slim, adaptable package

The 4CDH Series side discharge system is a feat of engineering.
Its slim format and light weight allow installation in tight spaces such as narrow backyards in Montreal, flat roofs of duplexes in Laval or small technical rooms in Longueuil.

Thanks to its intelligent design, it is possible to install up to four or five units in a single service vehicle, a considerable asset for HVAC contractors and for our AirGreen installation teams.

Quick and easy installation

Its architecture has been designed to minimize installation constraints.
The front access panel, easy maintenance hatch , and well-positioned connections allow our technicians to work more efficiently, reducing intervention time while ensuring clean and safe commissioning.

During our installations in Ahuntsic, Brossard and Terrebonne , this model stood out for its speed of integration, its silence, and its excellent air flow management in varied environments, whether new homes or renovations.

Remarkable silence, day and night

The CANAIR 4CDH R-454B redefines the notion of acoustic comfort.
Its noise level of only 34 dB(A) indoors and 52 dB(A) outdoors provides absolute quiet, even when operating at full power.
Thanks to Inverter technology , the compressor continuously adjusts its speed, avoiding the noisy stop/restart cycles typical of traditional models.

This soft sound is particularly appreciated in dense residential environments, where silence is an integral part of well-being.

Simplified maintenance: designed to last

Modular design and easy maintenance

The CANAIR 4CDH R-454B furnace indoor unit is designed to offer quick and easy maintenance .
Its modular components allow direct access to essential elements:

• Slide-out evaporator coil mounted on slide rail for quick cleaning;

• Removable filter on the front , easily accessible without tools;

• Intuitive electronic control board with clear digital display;

• Automatic diagnostic system that displays error codes to facilitate interventions.

This intelligent design reduces maintenance costs and ensures increased system longevity.

Constant Flow ECM Engine Reliability

The integrated ECM motor automatically adjusts fan speed based on air pressure and filter cleanliness, optimizing flow and performance.
This mechanism extends the life of the motor while maintaining maximum efficiency and reduced power consumption.

Green and responsible technology

Eco-friendly refrigerant R-454B

R-454B refrigerant represents the new generation of refrigerants with low environmental impact.
With a global warming potential (GWP) of only 466 , it is nearly 80% less polluting than older R-410A refrigerants.
It is an eco-responsible choice that meets new environmental standards without compromising system performance or reliability.

A reduced carbon footprint

By combining an ECM motor, inverter technology and a green refrigerant, the CANAIR 4CDH R-454B helps reduce greenhouse gas emissions .
This is an important step towards a greener home, perfectly aligned with Quebec's energy transition objectives.
