The power of lasting comfort, designed for the Quebec climate
At AirGreen, we believe a heating system should be much more than an appliance. It should be an everyday ally, delivering steady comfort, superior energy efficiency and unmatched peace of mind, even when the mercury hits bottom.
That is exactly what the CANAIR 4CDH R-454B Electric Furnace | 2.5 Tons offers — a high-efficiency central heating and cooling system, specially designed for Quebec’s harsh winters.
By combining Inverter technology, eco-friendly R-454B refrigerant, a compact side-discharge design and ENERGY STAR certified energy performance, this model redefines residential comfort.
A design built to face Quebec winters
The CANAIR 4CDH R-454B was born from a simple idea: deliver consistent performance whatever the outdoor temperature. Where many traditional systems lose efficiency as soon as the thermometer drops below -15°C, the Canair system keeps heating down to -30°C. According to the NEEP data for this system (AHRI 215449706), it delivers 23,800 BTU/h at -8°C (COP 2.76) and up to 32,600 BTU/h at -15°C (COP 1.96).
That means in the middle of February, while icy winds sweep Montreal or Laval, your home stays comfortable, warm and quiet. Even at -30°C, its maximum capacity reaches 20,100 BTU/h (COP 1.55): the 4CDH R-454B keeps turning electricity into useful heat while limiting energy waste.
Compact, intelligent and attractive design
Unlike often bulky top-discharge systems, the CANAIR 4CDH uses an innovative side discharge. This modern design allows installation in tight spaces — backyard, balcony, rooftop terrace or dense urban areas — while offering easy access for maintenance.
Its slim format and reduced weight make transport and installation much easier: a single technician can install it without heavy equipment. It is a practical solution for homeowners and for HVAC contractors looking for efficiency and flexibility.
Beyond its robustness, the 4CDH has a clean, modern look: its galvanized cabinet, coated with an anti-corrosion polyester-urethane finish, resists the elements up to 50% better than a traditional finish. Ideal for the humid, salty climate of Quebec’s coastal regions.
Quiet and soothing — performance with discretion
Complete comfort is not just about temperature. Quiet is an essential part of well-being at home.
The CANAIR 4CDH R-454B combines a constant-airflow ECM motor with Inverter technology, allowing it to run at a sound 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 Rosemont, Ahuntsic, Longueuil or Laval-des-Rapides, where quiet is a priority.
Leading energy efficiency and respect for the environment
In a world where energy sustainability is no longer a choice but a necessity, the CANAIR 4CDH stands out for its exceptional efficiency and reduced environmental footprint.
R-454B refrigerant: a new era for the environment
The R-454B refrigerant used in this model is both efficient and eco-responsible. With a global warming potential (GWP) of 466, it drastically reduces greenhouse gas emissions compared with older refrigerants such as R-410A.
That makes it an ethical, sustainable choice, eligible for Hydro-Québec’s LogisVert grant, with an indicative amount of $2,856 for this model.
ENERGY STAR and COLD CLIMATE V6.1 certified
The CANAIR 4CDH R-454B delivers remarkable performance:
SEER2: 16.8 — for optimal cooling efficiency.
HSPF2: 10.0 — for superior heating performance.
EER2: 11.7 — for controlled energy use.
In concrete terms, these figures translate into electricity savings that can exceed 25% compared with older non-certified HVAC systems.
Tailored comfort through intelligent engineering
The CANAIR 4CDH R-454B includes a series of advanced features that ensure precise comfort, intuitive use and long-term reliability.
1. Intelligent, adaptive airflow
The fan motor automatically adjusts its speed to the air pressure in the ducts, accounting for dirty filters or blocked coils. The result: constant, stable and balanced airflow, without wasted energy.
2. Complete self-cleaning system
The unit cleans and dries its coils after each cycle, preventing dust buildup and mold. You enjoy cleaner, healthier indoor air without complicated maintenance.
3. “Follow Me” function
Thanks to its smart wired Wi-Fi controller, the system keeps the temperature exactly where you are, for personalized comfort room by room.
4. Cold draft prevention
When heating starts, the system prevents any cold air from being blown, for a gentle, pleasant start.
5. Automatic protection and smart restart
After a power failure, the system restarts automatically with its previous settings. If a fault is detected, the self-diagnosis function shows a clear error code, making troubleshooting easier.
6. Automatic defrost and added safety
Built-in heating cables in the base and around the compressor prevent ice formation and ensure smooth operation even in extreme cold.
Simplified, fast maintenance
Maintenance is often the weak point of HVAC systems, but not with the CANAIR 4CDH. Every part of the furnace is designed for direct, effortless access:
Multiple access panels for the coil, motor and control boards.
Modular sliding evaporator, easy to remove for inspection and cleaning.
Front-access filters for regular maintenance without disassembly.
Only two control boards, minimizing the risk of failure and simplifying service.
The unit is compatible with several electric element sizes (5 to 25 kW), so capacity can be matched to the size of the home.
Complete warranty: peace of mind first
When you invest in a CANAIR furnace, you get a basic 10-year warranty on parts and the compressor, plus 6 years on labor, straight from the distributor. It is also possible to extend the labor warranty up to 10 years.
These warranties reflect Canair’s confidence in the durability of its products, as well as our commitment at AirGreen to impeccable after-sales service.
