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 Quebec's real climate

At AirGreen, we have been installing ADD-ON central heat pumps for years in very concrete settings: single-family homes that already have an electric furnace, multi-unit buildings where replacing the whole system would be needlessly costly, and light commercial buildings that need a reliable solution without a major overhaul of the existing HVAC infrastructure. The CANAIR 4CDH R-454B "ADD-ON" Central Heat Pump | 60000 BTU fits this field reality perfectly.

This 5-ton (60,000 BTU) model was designed for a common situation in Quebec: how to improve comfort, reduce energy use and modernize a heating and cooling system without tearing out what already works. In Montreal's residential neighbourhoods, Laval's larger lots, Longueuil's mixed-use buildings or properties on the North Shore and South Shore, this pragmatic approach makes all the difference.

A technical design focused on real, measurable, lasting performance

Heating capacity suited to Quebec winters

The CANAIR 4CDH R-454B 60,000 BTU is ENERGY STAR® cold climate certified and keeps heating down to -30°C. In practice, the system delivers steady heat even during long cold spells; in deep cold, the furnace's electric element covers the share that is missing.

NEEP heating data (AHRI combination 216720952):

• Nominal size: 5 tons (60,000 BTU)

• Heating at -8°C: 36,000 BTU/h (COP 2.14)

• Heating at -15°C: 43,000 BTU/h (COP 1.83)

• Heating at -30°C: up to 29,500 BTU/h (COP 1.43)

This stable output reduces backup heating cycles, improving both comfort and the predictability of electricity costs.

Efficient, consistent central air conditioning

In cooling mode, this 5-ton central heat pump keeps comfort even in open-concept buildings, multi-storey homes or light commercial spaces. Unlike some undersized systems, it controls the temperature effectively without overworking the compressor, which helps the equipment last longer.

Energy efficiency designed around real running costs

The energy performance of the CANAIR 4CDH R-454B is particularly relevant for owners who watch their long-term costs:

• SEER2: 15.2

• HSPF2 (region IV): 8.1

• EER2: 10.0

Where winter consumption is high, every efficiency gain shows up directly on the annual bill.

This combination (AHRI 216720952) is also on Hydro-Québec's LogisVert list of October 27, 2026, with an indicative amount of $4,320, which improves the return on investment for residential owners. Only Hydro-Québec confirms the aid granted.

R-454B refrigerant: a responsible, forward-looking choice

R-454B is an A2L refrigerant with a global warming potential of 466, compared with 2,088 for R-410A. Its use in the CANAIR 4CDH central heat pump meets current environmental requirements.

In practical terms, this means:

• a smaller carbon footprint than older refrigerants,

• a refrigerant that meets current requirements,

• a coherent choice for environmentally minded clients, with no compromise on performance.

The ADD-ON concept: a smart, economical approach

Keep what exists while improving performance

The ADD-ON format integrates the central heat pump with an existing system, usually an electric furnace that still works. This approach offers several advantages:

• lower costs than replacing the whole system,

• less electrical and structural work,

• shorter installation times,

• a gradual, controlled energy transition.

In apartment buildings and homes built between the 1990s and 2010s, this configuration is often the most logical, technically and financially.

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

The CANAIR 4CDH outdoor unit uses side discharge, a particularly relevant choice in urban and suburban settings. This more compact format makes it easier to:

• install in narrow backyards,

• place the unit near walls while respecting clearances,

• fit it on rooftop terraces or in areas with limited access.

For AirGreen, this means more flexibility during installation and fewer compromises for the client.

The cased coil: simple, robust and easy to maintain

A coil that installs on your furnace

The CEB-60MX2421 cased coil (24.5 × 21 × 28 in.) is installed on the existing furnace, vertically or horizontally. This versatility is essential in finished basements, narrow mechanical rooms and commercial buildings where space is limited.

The furnace blower: airflow worth setting right

AirGreen pays particular attention to HVAC maintenance, which is often overlooked at purchase. With an ADD-ON system:

• the existing furnace blower moves the air across the coil; AirGreen checks and adjusts that airflow at start-up,

• the coil stays accessible for inspection and cleaning,

• the refrigerant line connections are 3/8 in. and 7/8 in.

The result: faster service visits, less downtime and better-controlled maintenance costs over the system's life.

Features that are truly useful every day

• automatic defrost of the outdoor unit for frequent freeze-thaw cycles,

• inverter compressor, which modulates its output instead of constantly starting and stopping,

• A2L refrigerant leak detection, connected and checked during installation.

Careful commissioning helps reduce the risk of breakdowns in winter.

Key technical data – 60,000 BTU model

• Outdoor model: 4CDH2060C21

• Cased coil: CEB-60MX2421

• Nominal size: 5 tons (60,000 BTU)

• Voltage: 220 V

• MCA: 40 A

• MOP: 40 A

• Outdoor sound level: about 65 dB(A)

• Outdoor dimensions: 37.48 × 16.34 × 52.48 in.

These specifications make it a solid choice for large homes, duplexes and triplexes, and many light commercial buildings.
