The power of lasting comfort, designed for the Quebec climate

At AirGreen , we believe that a heating system should be more than just an appliance. It should be a daily companion , capable of providing consistent comfort, superior energy efficiency, and unparalleled peace of mind, even when the mercury plummets.
That's exactly what the CANAIR 4CDH R-454B | 2.5 Ton Electric Furnace offers — a high-efficiency central heating and air conditioning system, specially designed for Quebec's harsh winters.

By combining inverter technology , environmentally friendly R-454B refrigerant , compact side-discharge design and ENERGY STAR certified energy performance , this model redefines the notion of residential comfort.

A design tailored to face Quebec winters

The CANAIR 4CDH R-454B was born from a simple idea: to deliver consistent performance, regardless of the outside temperature. While many traditional systems lose efficiency as soon as the thermometer drops below -15°C, the Canair system continues to operate down to -30°C while maintaining 100% heating capacity at -20°C .

This means that in the middle of February, when the icy wind is blowing through Montreal or Laval, your home remains comfortable, warm, and quiet. With a Coefficient of Performance (COP) of up to 1.8 , 4CDH R-454B maximizes the conversion of electrical energy into useful heat, minimizing energy waste.

Compact, smart and aesthetic design

Unlike often bulky top-discharge systems, the CANAIR 4CDH model adopts an innovative side discharge . This modern design allows installation in tight spaces —backyards, balconies, rooftop terraces, or even dense urban areas—while providing simplified access for maintenance .

Its slim design and low weight make it much easier to transport and install: a single technician can install it without heavy equipment. It's a practical solution for both homeowners and HVAC contractors looking for efficiency and flexibility.

In addition to its robustness, the 4CDH seduces with its sober and modern aesthetic: its galvanized finish casing, covered with an anti-corrosion urethane polyester coating , resists bad weather up to 50% better than a traditional finish. Ideal for the humid and salty climate of the coastal regions of Quebec.

Quiet and soothing — performance with discretion

Total comfort isn't just about temperature. Silence is an essential component of well-being at home.
The CANAIR 4CDH R-454B incorporates a constant airflow ECM motor , coupled with inverter technology , allowing it to operate at a noise level as low as 27.5 dB(A) — quieter than a soft conversation.

This noise reduction applies to both the indoor and outdoor units, making it an ideal option for dense residential areas such as the Rosemont, Ahuntsic, Longueuil or Laval-des-Rapides neighborhoods , where peace and quiet are paramount.

Cutting-edge energy efficiency and environmental friendliness

In a world where energy sustainability is no longer a choice but a necessity, the CANAIR 4CDH stands out for its exceptional performance and reduced ecological footprint .

R-454B Refrigerant: A New Era for the Environment

The R-454B refrigerant used in this model is both efficient and environmentally friendly. With a global warming potential (GWP) of 466 , it drastically reduces greenhouse gas emissions compared to older refrigerants like R-410A.

This makes it an ethical and sustainable choice , supported by provincial energy transition programs, including the LogisVert program , which offers up to $2,856 in subsidies for the purchase of this model (updated July 2025).

ENERGY STAR and COLD CLIMATE V6.1 certified

The CANAIR 4CDH R-454B displays remarkable performance:

• SEER2: 16.8 — for optimal air conditioning efficiency.

• HSPF2: 10.0 — for superior heating efficiency.

• EER2: 11.7 — for controlled energy consumption.

These figures translate into concrete electricity savings of up to 25% compared to older, non-certified HVAC systems.

Tailor-made comfort through intelligent engineering

The CANAIR 4CDH R-454B incorporates a series of advanced features that ensure precise comfort, intuitive operation and long-term reliability.

1. Intelligent and adaptive airflow

The fan motor automatically adjusts its speed according to the air pressure in the ducts, taking into account clogged filters or blocked coils. The result: a constant, stable and balanced airflow , without wasting energy.

2. Complete self-cleaning system

The unit cleans and dries its coils after each cycle, preventing dust buildup and mold growth. You enjoy cleaner, healthier indoor air without complex maintenance.

3. “Follow Me” function

With its smart Wi-Fi wired controller , the system maintains the temperature exactly where you are, for personalized room-by-room comfort.

4. Prevention of cold draft

When starting heating mode, the system prevents any diffusion of cold air, providing a smooth and pleasant start .

5. Automatic protection and smart restart

In the event of a power outage, the system automatically restarts while maintaining its previous settings. And if an anomaly is detected, the self-diagnostic function displays a clear error code, facilitating troubleshooting.

6. Automatic defrosting and increased safety

Heating cables integrated into the base and around the compressor prevent ice formation and ensure smooth operation even in extreme cold.

Simplified and rapid maintenance

Maintenance is often the weak point of HVAC systems, but not with the CANAIR 4CDH. Every element of the furnace has been designed for direct and effortless access :

• Multiple access panels for coil, motor and electronic boards.

• Modular sliding evaporator , easy to remove for inspection and cleaning.

• Filters accessible from the front for regular maintenance without disassembly.

• Only two electronic cards , minimizing the risk of failure and simplifying maintenance.

The unit is compatible with several electrical element powers (5 to 25 kW), allowing the capacity to be adjusted according to the size of the house.

Comprehensive warranty: peace of mind above all

When you invest in a CANAIR furnace, you benefit from a 10-year basic warranty on parts and the compressor, as well as an optional 10-year warranty on labor .
These guarantees reflect Canair's confidence in the durability of its products, but also our commitment, at AirGreen , to offering impeccable after-sales service.
