CANAIR 4CDH Central Heat Pump - R454B | 1.5 Tons
The ideal choice for four-season comfort in Montreal, Laval and on the South Shore
At AirGreen, we know Quebec's climate puts every HVAC system to the test. That is why we offer solutions built to last, combining performance, energy efficiency and reliability. Among our flagship models, the CANAIR 4CDH – R-454B Central Heat Pump | 1.5 tons stands out as a true benchmark for residential comfort. Compact, quiet and eco-friendly, it is built for the harsh winters and humid summers of Greater Montreal.
A system designed for Quebec's climate
This CANAIR 4CDH central heat pump heats down to -30°C. According to NEEP data for this system (AHRI 215449704), it delivers 15,000 BTU/h at -8°C (COP 2.6), 18,000 BTU/h at -15°C (COP 2.0) and up to 12,000 BTU/h at -30°C (COP 1.41). Its inverter compressor automatically adjusts its output to keep the temperature stable and reduce electricity use.
Thanks to its R-454B refrigerant, with a low global warming potential (466, compared with 2,088 for R-410A), this model helps reduce your carbon footprint without compromising performance. It is an ideal solution for families who want an eco-friendly, durable system.
A compact, flexible and smart format
One of the 4CDH system's biggest strengths is its side-discharge design, slimmer and lighter than traditional top-discharge units. This design makes installation much easier in tight spaces, whether a backyard, a rooftop terrace or a service area in the city.
Our AirGreen technicians especially appreciate how easy it is to handle: one person can carry it and set it on a pad, which reduces installation time and labour costs.
Remarkably quiet operation
The 4CDH was designed for superior acoustic comfort. Its variable-speed motor, combined with inverter technology, allows an indoor sound level as low as 33 dB(A). Outdoors, the sound level is 59 dB(A), a real asset in residential areas where quiet matters.
The result: a system you forget is there, while every room stays pleasant.

Thanks to its smart constant-airflow fan, the system automatically adjusts its output to the condition of the filters or the internal pressure, ensuring optimal airflow and less wasted energy.
Comfort, simplicity and innovation together
The included wired Wi-Fi controller lets you set the temperature intuitively from a phone or tablet. The "Follow Me" function senses the temperature around the remote for precise comfort where you are.
Self-cleaning functions keep the coils clean and dry, preventing mould and extending the system's life. And automatic restart after a power outage keeps your previous settings, welcome peace of mind during winter storms.
Simplified installation and maintenance
Our AirGreen teams favour this model for its easy maintenance. The modular evaporator coil slides out easily for cleaning or inspection. The quick-access panel and easily replaceable filter make the 4CDH a unit built to last, while keeping maintenance costs low.
The multi-position indoor unit allows horizontal, vertical, upflow or downflow installation, giving full flexibility for any residential or light commercial configuration.
Ecology and energy efficiency hand in hand
R-454B refrigerant, classified A2L, has a much lower global warming potential than older gases such as R-410A. This eco-friendly choice aligns the CANAIR 4CDH series with new environmental standards without compromising energy performance.
It also means our clients get an environmentally friendly HVAC system, eligible for Hydro-Québec's LogisVert program with an indicative amount of $1,800. Only Hydro-Québec confirms the aid granted.
