Quebec efficiency redesigned for lasting comfort
At AirGreen, we believe an efficient HVAC system shouldn’t just heat a house: it should create smart, quiet and energy-efficient comfort, suited to Quebec’s harsh climate.
That is exactly what the CANAIR 4CDH R-454B Electric Furnace offers: a technological gem designed to pair with the central heat pump of the same name — the 4CDH side-discharge system, a compact, robust and highly efficient solution.
A system designed for the Quebec climate
Built to perform down to –30°C, the CANAIR 4CDH furnace delivers steady, continuous heat even in the most extreme cold.
Thanks to its Inverter technology, the system keeps an even temperature, without the unpleasant swings typical of conventional systems.
The central heat pump it pairs with delivers up to 19 SEER2 and 9.7 HSPF2, while the electric furnace provides smart backup heat with its 5 to 25 kW modules.
This combination of performance, quiet and adaptability makes the 4CDH R-454B series a natural choice for homes in Montreal, Laval, Longueuil, the North Shore and the South Shore.
Compact format, maximum flexibility
In urban settings or homes with limited space, every inch counts.
The CANAIR 4CDH stands out for its slim, lightweight format, easy to install in a basement, utility closet or small mechanical room.
Its constant-airflow ECM motor ensures optimal airflow whatever the pressure in the duct network — an asset that improves durability and reduces energy use.
Dimensions (1.5 ton): 17.52 × 21.02 × 45.00 in
Net weight: 105 lb
Power supply: 220V / 60 Hz
Refrigerant: R-454B (low-GWP A2L)
Simplified maintenance and long life
The CANAIR furnace is designed for technicians as much as for owners:
Modular electrical components with only two control boards (PCB) for quick servicing.
Easy-access filter through a removable front hatch.
Modular sliding evaporator coil for easy removal during maintenance.
Integrated electronic expansion valve for precise refrigerant flow control.
Automatic A2L refrigerant leak detection, for system safety and the customer’s peace of mind.
Maintenance is hassle-free — essential for years of optimal performance.
Quiet, powerful and efficient
With an indoor sound level as low as 33 dB(A), the CANAIR 4CDH furnace is one of the quietest in its class.
Paired with its side-discharge outdoor heat pump, it maintains steady comfort without excessive noise, even in the middle of winter.
Its variable-speed motor automatically adjusts power to keep a constant airflow, reducing energy losses and extending the life of internal components.
ENERGY STAR® Cold Climate certified performance
The CANAIR 4CDH R-454B series is Cold Climate V6.1 certified, confirming its ability to deliver reliable heat in the most extreme conditions.
The performance is impressive:
| Parameter | Value |
|---|---|
| Nominal heating capacity | 19,000 BTU/h |
| Nominal cooling capacity | 18,000 BTU/h |
| SEER2 efficiency | 19.0 |
| HSPF2 | 9.7 |
| Sound level | 33 / 41 dB(A) |
| Operating temperatures | –30°C to +50°C |
This exceptional energy efficiency lowers operating costs while maximizing indoor comfort, summer and winter.
An eco-responsible approach with R-454B refrigerant
CANAIR systems use R-454B refrigerant, known for its low global warming potential (GWP of 466) — far lower than older refrigerants.
This choice reflects the brand’s commitment to a greener future that meets new environmental regulations.
By choosing the CANAIR 4CDH, you take a concrete step for the environment while lowering your long-term energy costs.
