CANAIR 4CDH R-454B "ADD-ON" Central Heat Pump | 60,000 BTU - Cased Coil

• BROCHURE

A central ADD-ON solution designed for existing buildings and the real Quebec climate

At AirGreen , we have been installing ADD-ON central heat pump systems for years in very real-world situations: single-family homes already equipped with an electric furnace, multi-unit buildings where a complete system replacement would be unnecessarily expensive, and light commercial buildings requiring a reliable solution without a major overhaul of the existing HVAC infrastructure. The CANAIR 4CDH R-454B | 60,000 BTU ADD-ON Central Heat Pump fits perfectly into this real-world context.

This 5-tonne (60,000 BTU) model was designed to address a common problem in Quebec: how to significantly improve comfort, reduce energy consumption, and modernize a heating and cooling system without demolishing what's already working. In Montreal 's residential neighborhoods, the larger areas of Laval , the mixed-use buildings of Longueuil , or properties on the North and South Shores , this type of pragmatic approach makes all the difference.

A technical design geared towards real, measurable and sustainable performance

Heating capacity adapted to Quebec winters

The CANAIR 4CDH R-454B 60,000 BTU is designed to operate down to -30°C , which corresponds to the most demanding winter conditions encountered in Quebec. In practice, this means that the system continues to provide stable heat even during prolonged cold spells, without relying excessively on supplementary electric heating elements.

Key data on heating:

• Rated power : 60,000 BTU

• Power at -15°C : approximately 30,400 BTU

• COP at -15°C : around 1.8

During several installations carried out by AirGreen in large single-family homes in Boucherville and Boisbriand , this thermal stability resulted in a significant reduction in supplementary heating cycles, improving both comfort and the predictability of electricity costs.

Efficient and constant central air conditioning

In cooling mode, this central heat pump offers a 60,000 BTU capacity, sufficient to maintain consistent comfort in open-concept buildings, multi-story homes, or light commercial spaces. Unlike some undersized systems, it allows for efficient temperature control without overworking the compressor, which directly contributes to the equipment's longevity.

Energy efficiency designed for actual operating costs

The energy performance of the CANAIR 4CDH R-454B is particularly relevant for homeowners who are monitoring their long-term expenses:

• SEER2 : up to 16.0

• HSPF2 (IV) : up to 8.5

• EER2 : approximately 10.0

These values ​​place the system in a highly competitive category for large-capacity central HVAC installations . In a context of fluctuating electricity rates and high winter consumption, every efficiency gain is directly reflected in the annual bill.

In addition, this model is eligible for the $2,880 LogisVert provincial grant , which significantly improves the return on investment for residential owners.

R-454B refrigerant: a responsible and future-proof choice

R-454B is an A2L type refrigerant with a low global warming potential. Its use in the CANAIR 4CDH central heat pump is significant: it meets both current environmental requirements and future regulatory guidelines.

In practical terms, this means:

• a reduced carbon footprint compared to older refrigerants,

• improved sustainability of the system in the face of evolving regulations,

• a coherent solution for environmentally conscious customers without compromising on performance.

In several recent projects carried out by AirGreen in Montreal and on the South Shore , this criterion weighed heavily in the final decision of the owners.

The ADD-ON concept: a smart and economical approach

Maintaining the existing system while improving performance

The ADD-ON format allows the central heat pump to be integrated into an existing system, usually a still-functional electric furnace . This approach offers several advantages:

• cost reduction associated with a complete system replacement

• limitation of electrical and structural work,

• shorter installation times,

• gradual and controlled energy transition.

In apartment buildings and houses built between the 1990s and 2010s, this configuration is often the most logical from a technical and financial point of view.

Side-discharge outdoor unit: a real advantage in the field

The CANAIR 4CDH outdoor unit uses a side discharge , a particularly relevant choice in urban and semi-urban environments. This more compact design facilitates:

• installation in narrow backyards ,

• Positioning close to the walls while respecting clearances,

• integration on rooftop terraces or in areas with limited access.

For AirGreen, this translates into more flexibility during installation and fewer compromises imposed on the customer.

Indoor unit: simplicity, robustness and ease of maintenance

Multi-position configuration to adapt to existing buildings

The indoor unit associated with the 60,000 BTU model is designed for installation:

• upward vertical,

• downward vertical,

• horizontal.

This versatility is essential in finished basements, narrow mechanical rooms, or commercial buildings where available space is limited.

Components designed for service and durability

AirGreen places particular importance on HVAC maintenance , which is often overlooked at the time of purchase. This system includes:

• a constant flow ECM motor , ensuring stable air distribution,

• a sliding modular evaporator coil made of hydrophilic aluminum,

• direct access panels for key components,

• a simplified internal design reducing the number of critical parts.

The result: faster interventions, less downtime and better controlled maintenance costs over the system's lifetime.

Built-in features that are genuinely useful on a daily basis

The CANAIR 4CDH R-454B does not rely on gimmicky features, but on concrete elements that improve the user experience:

• Automatic defrosting optimized for frequent freeze/thaw cycles,

• external heating cables to limit ice accumulation,

• A2L refrigerant leak detection with automatic shut-off,

• Automatic restart after power failure

• Optional wired Wi-Fi controller for precise system management.

In several multi-unit buildings equipped by AirGreen, these functions have made it possible to significantly reduce service calls during the winter.

Key technical data – 60,000 BTU model

• Exterior model : 4CDH2060C21

• Interior model : CEB-60MX2421

• Rated capacity : 60,000 BTU

• Voltage : 220 V

• MCA : 40 A

• MOP : 40 A

• Outdoor noise level : approximately 65 dB(A)

• External dimensions : 37.48 × 16.34 × 52.48 in

These features make it a solid choice for large residences, duplexes and triplexes, as well as many light commercial buildings.

Long-term guarantee and peace of mind

The CANAIR 4CDH R-454B central heat pump is offered with:

• 10 years on the compressor ,

• 10-year warranty on parts ,

• possibility of an extended warranty on labor .

At AirGreen, we emphasize a fundamental point: the reliability of an HVAC system depends as much on the quality of the equipment as on the rigor of its installation.
