CANAIR 4CDH Central Heat Pump – R454B | 2.5 Tons: The perfect combination of performance, reliability and eco-responsibility

A central heat pump designed for Quebec's climate

At AirGreen , we know that the comfort of Quebec homes depends on an HVAC system capable of withstanding the harshest winters and the hottest summers. That's why we offer the CANAIR 4CDH Central Heat Pump – R454B | 2.5 Tons , a highly efficient , quiet , environmentally friendly heating and air conditioning solution that's perfectly suited to Quebec's climate .

Designed to deliver optimal performance even at -30°C , this central heat pump combines inverter technology , a constant airflow ECM motor and R-454B refrigerant gas , one of the most eco-responsible on the market. It guarantees superior energy efficiency, stable comfort in all seasons and a significant reduction in energy costs for your home in Montreal , Laval , Longueuil , on the North Shore or the South Shore .

Remarkable energy efficiency in all seasons

The CANAIR 4CDH – R454B has been designed to maximize every watt of energy consumed. With its ENERGY STAR® and Cold Climate V6.1 certified performance, it ranks among the best in its category:

• SEER2 (Cooling Efficiency) : 16.8

• HSPF2 (heating efficiency) : 10.0

• EER2 (instantaneous energy efficiency) : 11.7

This combination of efficiency allows it to ensure consistent comfort while significantly reducing your electricity bill . The inverter compressor automatically adjusts its speed according to the actual needs of the home, ensuring smooth operation without jolts or overconsumption.

Stable and quiet performance

Thanks to its ingenious design and advanced technology, the 4CDH operates with extremely low noise emissions : only 60.5 dB(A) outdoors and between 27.5 and 46 dB(A) indoors. This level of silence guarantees unparalleled acoustic comfort , ideal for single-family homes, duplexes and urban dwellings where peace and quiet is essential.

A compact, elegant and flexible design

The CANAIR 4CDH's side-discharge design is a major advantage for homeowners and installers. Unlike top-discharge systems, this configuration reduces the unit's height and makes it easier to install in tight spaces such as backyards, decks, or narrow driveways.

Concrete advantages of the side discharge design:

• Slim format and reduced weight , allowing quick and secure installation.

• Easy transport : a single technician can carry the unit to the site.

• Optimized lateral air circulation for better thermal efficiency.

• Modern aesthetics : the design blends harmoniously into any residential environment.

Thanks to its compact structure — outdoor unit measuring 37.24 x 16.14 x 31.89 in and indoor unit measuring 21.02 x 21.02 x 49.02 in — the 4CDH adapts to all installation realities, whether in a basement, a mechanical room or a converted attic.

Absolute comfort: power, stability and precision

Efficient heating down to -30°C

Even in the middle of January, when the thermometer dips below -25°C, the CANAIR 4CDH maintains 100% of its heating capacity down to -20°C , and continues to operate efficiently down to -30°C . Its COP of 1.8 at -20°C is a testament to its exceptional performance even in the most demanding conditions.

Inverter technology: precision and economy

The inverter compressor continuously adjusts the operating speed to keep the interior temperature stable to within a tenth of a degree. The result: fewer on/off cycles , less wear , less noise , and more energy savings .

Tailor-made comfort

The heat pump comes with a smart Wi-Fi wired controller that allows for precise temperature adjustment, even from a distance. With the “Follow Me” feature, the built-in sensor adjusts the temperature based on the remote control's location—ideal for maintaining consistent comfort in every room.

A design thought for durability and easy maintenance

Smart and accessible indoor unit

The 4CDH indoor unit features a modular slide-out evaporator , making cleaning and maintenance easy. Technicians can easily access all key components, significantly reducing maintenance time.
Its simplified electrical system includes only two printed circuit boards (PCBs), limiting the risk of failure and optimizing long-term reliability.

Constant flow ECM motor

The ECM (Electronically Commutated Motor) automatically adjusts airflow to compensate for pressure fluctuations due to clogged filters or coils. This ensures:

• Even air distribution throughout the house.

• A reduction in energy waste .

• Extended system life .

Easy daily maintenance

The air filter is easily accessible through a front hatch, simplifying regular cleaning. Additionally, the unit features a self-cleaning system that dries the indoor coil after each cooling cycle, preventing the growth of mold and bacteria.

Safe and eco-responsible technology

R-454B refrigerant: environmentally friendly

R-454B refrigerant gas is an environmentally friendly and sustainable choice. With a global warming potential (GWP) of only 466 , it reduces greenhouse gas emissions by more than 65% compared to the old R-410A. Class A2L , it combines energy efficiency and safety thanks to an integrated detection system that automatically stops operation in the event of a leak.

Reduced carbon emissions

Choosing CANAIR 4CDH means investing in a solution that promotes Quebec's energy transition . By replacing an old oil or natural gas system, you contribute directly to reducing polluting emissions while benefiting from provincial subsidies of up to $2,856 (LogisVert program) .

Total reliability and intelligent protection

Automated security

In the event of a malfunction or power outage, the heat pump automatically restarts while maintaining its previous settings. In the event of an anomaly, the self-diagnostic system detects the problem and displays a clear error code, allowing for rapid intervention.

Automatic defrosting

During periods of intense cold, the automatic defrost function prevents ice from forming on the evaporator and maintains optimal system performance, even in a humid or low temperature environment.

Exceptional guarantee: peace of mind for 10 years

Every CANAIR 4CDH heat pump comes with a 10-year basic parts and compressor warranty . For maximum coverage, AirGreen also offers a 10-year extended labor warranty , ensuring complete peace of mind for the life of the system.

It is this combination of proven technology , professional service and a solid warranty that makes the 4CDH one of the best HVAC investments available today for residential homeowners.
