The perfection of Quebec comfort by AirGreen

At AirGreen , we always have a clear mission: to offer our customers in Montreal, Laval, Longueuil, the North Shore and the South Shore HVAC systems that combine performance, reliability, energy savings and absolute comfort . This is exactly what the CANAIR 4CDH - R454B | 4 Ton Central Heat Pump represents, a true revolution in the field of central heating and air conditioning.

Designed and developed by CANAIR , a proudly Quebec company founded in 1971, this centralized heat pump stands out for its exceptional energy efficiency , cutting-edge technology , and robustness designed for the Quebec climate. It is much more than just a device: it is a lasting investment in quality of life and peace of mind.

Remarkable and measurable energy efficiency

The CANAIR 4CDH – R454B is among the most efficient systems in its category , thanks to a design focused on energy performance and loss reduction.

• Cooling Capacity : 48,000 BTU (4 tons)

• Heating capacity : 50,000 BTU

• SEER2 : 16.5

• HSPF2 : 9.5

• EER2 : 10.5

• ENERGY STAR® and Cold Climate V6.1 certified

These high indices translate concretely into a reduction in electricity consumption , without compromising on power. The Inverter technology, at the heart of the system, continuously adjusts the speed of the compressor and the fan to maintain a stable temperature, while minimizing energy fluctuations.

The result: a home that's always comfortable, a reduced electricity bill, and a significantly reduced environmental impact.

Consistent performance, even at -30°C

The main challenge for an HVAC system in Quebec is the harsh climate . The CANAIR 4CDH is specially designed to maintain stable performance even during the worst cold snaps .

• Continuous operation down to -30°C

• 100% heating capacity down to -20°C

• COP up to 1.8 at very low temperature

With this power, comfort is guaranteed at all times, even in the middle of January, when the mercury dips well below zero. No more compromising between energy and warmth—the CANAIR 4CDH instantly responds to your heating or cooling needs, regardless of the outside temperature.

A smart, compact and quiet design

One of the major advantages of the CANAIR 4CDH central heat pump is its side discharge design. This innovative format, thinner and lighter than vertical discharge models, offers unparalleled installation flexibility .

Advantages of the side discharge design:

• Considerable space saving : ideal for backyards, terraces or flat roofs.

• Simplified installation : can be transported and installed by a single technician.

• Adaptability : configuration possible in vertical or horizontal mode depending on the space available.

All this without sacrificing performance. Better still, this design ensures quiet operation , reaching only 65 dB(A) outside and 34 dB(A) inside, for exceptional acoustic comfort.
This way you benefit from powerful air conditioning and heating… without ever hearing the machine.

Technology at the service of reliability

Each component of the CANAIR 4CDH is designed to last and simplify the lives of users and technicians alike.

High efficiency indoor unit

• Constant flow ECM motor (up to 0.8 in H₂O) ensures stable and uniform airflow.

• Modular, sliding aluminum evaporator coil for easy maintenance.

• Quick access panels for filter, electronic board and coil maintenance.

• 115/230 V compatibility , allowing easy adaptation to any residence.

Simplified maintenance

With only two integrated electronic boards , maintenance is intuitive and fast. Technicians can easily access circuits and components for immediate diagnosis, significantly reducing intervention times and maintenance costs.

Exemplary safety and durability

The CANAIR 4CDH incorporates numerous automatic protections ensuring safe and stable operation:

• A2L (R-454B) refrigerant leak detection

• Built-in self-diagnosis and self-protection

• Automatic defrost to prevent ice buildup

• External heating cables protect the compressor during restarts in very cold weather

• “Follow Me” function maintaining the exact temperature where the remote control is located

• Automatic restart after power failure

• Cold air draft protection when starting in heating mode

Every design detail is designed to ensure complete peace of mind and increased system longevity .

An ecological and future-oriented solution

The use of R-454B refrigerant gas marks an important step towards reducing greenhouse gas emissions . This A2L fluid with low global warming potential (GWP 466) offers superior performance while minimizing environmental impact.

The CANAIR 4CDH allows you to heat and cool your home without harming the planet . Powered entirely by electricity, it eliminates dependence on fossil fuels and reduces CO₂ emissions, while benefiting from a renewable and stable energy source in Quebec .

In other words: an ecological, economical and sustainable choice , ideal for owners concerned about their carbon footprint.

Guarantee, peace of mind and long-term savings

At AirGreen, we know that a good HVAC system is not only measured by its performance, but also by the peace of mind it provides .

That's why the CANAIR 4CDH comes with a full 10-year parts and compressor warranty , as well as a 10-10-10 extended warranty option , also covering labor for 10 years.

In addition, this model is eligible for the LogisVert subsidy , for an amount of up to $4,440 (updated July 2025) — a considerable advantage to reduce the initial investment.

Thanks to its energy efficiency and durability, this heat pump also provides real savings on heating and cooling costs , year after year.

Robust and durable construction

The outdoor unit cabinet is constructed of galvanized steel coated with a polyester-urethane finish , guaranteeing 50% greater resistance to corrosion compared to conventional finishes.
