The perfect combination of performance, reliability and energy efficiency
At AirGreen , we know that home comfort isn't just about warmth or coolness—it's about reliability , durability , and peace of mind . That's why we recommend the CANAIR 4CDH R-454B | 2 Ton Electric Furnace , a high-performance solution designed to meet the climate realities of Quebec.
This energy-efficient central system offers an optimal balance between power, reduced consumption, and environmental friendliness. It is designed for homeowners looking for a complete, uncompromising heating and cooling solution , suited to Montreal's harsh winters and southern Quebec's hot, humid summers.
Designed and manufactured for Quebec homes, this furnace represents the future of residential comfort : quiet, intelligent, energy-efficient and eco-responsible.
Advanced design for optimal comfort
The CANAIR 4CDH R-454B is a side discharge system —a configuration that changes everything. Unlike vertical discharge models, it is more compact, lighter, and more flexible , making it easy to install in a variety of residential environments: small yards, basements, decks, or tight spaces.
Its modern design is accompanied by a robust construction, careful sound insulation and an inverter technology motor . The latter continuously adjusts the power to offer smooth and stable operation , without jolts or temperature fluctuations.
Remarkably quiet operation
With a minimum noise level of 28 to 44 dB(A) , the CANAIR 4CDH R-454B offers an impressively quiet acoustic experience. Even at full performance, it remains almost imperceptible to the ear. This silence is made possible by a high-performance compressor, variable-speed fans and an anti-vibration design that absorb unwanted resonances.
Constant comfort, even below -30°C
The CANAIR 4CDH R-454B heating technology has been specially calibrated for extreme Quebec winters . It maintains 100% of its heating capacity at -20°C , and remains fully functional down to -30°C . With a coefficient of performance (COP) of up to 1.8 , it provides superior energy efficiency, efficiently transforming every watt of electricity into useful heat.
A smart motor with constant airflow
The furnace is equipped with a constant airflow ECM motor, which measures air pressures in the ducts in real time. If a filter is clogged or a coil is partially blocked, the system automatically adjusts its power to maintain optimal airflow. The result: reduced energy consumption, increased efficiency, and consistent comfort throughout the house.
An energy-efficient and durable device
The 4CDH R-454B model achieves efficiency levels among the best in its class:
-
SEER2: 18.3 (cooling)
-
HSPF2: 10.0 (heating)
-
EER2: 11.7
These values demonstrate superior energy efficiency , allowing households to reduce their electricity consumption without sacrificing comfort. On average, installing a furnace in this range can reduce operating costs by up to 30% compared to a traditional gas or oil system.
An ecological refrigerant
The CANAIR 4CDH R-454B uses the new R-454B refrigerant , known for its low global warming potential (GWP of 466) . This represents a reduction of more than 75% compared to older fluids such as R-410A. This choice helps reduce the system's carbon footprint while meeting the latest environmental standards.
A design 100% adapted to Quebec
Designed and distributed by a proudly Quebec company since 1971 , CANAIR technology has been tested and perfected to meet Quebec's unique climatic conditions: intense frost, high humidity, and large seasonal variations.
Easy maintenance and exemplary durability
A practical and accessible design
The indoor unit (model 4CDH2024F21) has been designed to make life easier for owners and technicians . The access panels to the blower, coil and electrical components are removable, allowing for quick and hassle-free maintenance.
The modular aluminum sliding evaporator can be removed for cleaning or inspection, while the electrical components are limited to two main circuit boards, greatly simplifying maintenance.
