CANAIR 4CDH R-454B "ADD-ON" Central Heat Pump | 1.5T - Cased Coil

• BROCHURE

A central heat pump designed for Quebec's climate and existing buildings

At AirGreen , we have been installing and optimizing heating, ventilation, and air conditioning (HVAC) systems for over 15 years in Montreal , Laval , Longueuil , and on the North and South Shores . The CANAIR 4CDH R-454B | 1.5T "ADD-ON" Central Heat Pump precisely addresses a reality we encounter every week: properties already equipped with an electric furnace or a functional central system, but one that is energy-inefficient, noisy, or expensive to operate.

The ADD-ON concept is a smart and pragmatic approach. It's not about unnecessarily replacing everything, but about adding a high-efficiency central heat pump that works in synergy with the existing equipment. The result: superior comfort, reduced electricity consumption, and a controlled energy transition, without major renovations or compromising reliability.

The 1.5-tonne (18,000 BTU) version of the CANAIR 4CDH is particularly well-suited for well-insulated single-family homes, newer semi-detached houses, townhouses, and some modernized duplexes. It's a size we often recommend when a precise balance is needed between performance, overall cost, and seasonal efficiency.

True winter performance, even in extreme cold.

Reliable heating down to -30°C

One of the major strengths of the CANAIR 4CDH R-454B lies in its ability to maintain stable heating operation down to -30°C . In the Quebec context, this feature truly transforms the user experience.

In practical terms, this means that for much of the winter, the heat pump provides the primary heating, reducing the need for the backup electric element. In the field, at clients' homes in Laval and on the North Shore , we observe:

• a more uniform indoor temperature, without uncomfortable fluctuations,

• fewer abrupt on/off cycles,

• a more consistent feeling of warmth, even in very cold weather.

At -15°C , the heating power remains high for a unit of this size, allowing it to effectively cover the thermal needs of many typical residences in the Montreal area.

Energy efficiency that translates into concrete savings

Beyond the technical specifications, it's the real results that count. The CANAIR 4CDH 1.5T Central Heat Pump offers:

• excellent efficiency in summer air conditioning

• optimized seasonal heating efficiency,

• compatibility with the requirements of grant programs.

In projects carried out in Longueuil , particularly in open-plan houses, this efficiency translates into a significant decrease in air conditioning costs in the summer and a measurable reduction in the winter electricity bill, especially when the old system relied solely on direct electric heating.

R-454B refrigerant: a choice for the future

R-454B is a next-generation refrigerant, selected for its balance of performance, safety, and reduced environmental impact. Compared to older fluids still found in many central systems, it has a significantly lower global warming potential , making it a logical choice for homeowners concerned about the sustainability of their investment.

For our clients on the South Shore , who are often attentive to environmental issues but demanding in terms of performance, this represents:

• compliance with current and future standards,

• a system designed to remain relevant for many years,

• real added value in the event of a future resale of the property.

At AirGreen , we have supported several clients in the transition to this type of refrigerant, and when well planned, the integration is done without unnecessary complexity.

An indoor unit designed for flexibility and durability

Compact size and maximum adaptability

The indoor unit associated with this model is distinguished by its versatile installation . It can be configured in a vertical or horizontal position, which facilitates its integration into sometimes restrictive mechanical spaces: finished basements, narrow technical rooms or dedicated cupboards.

In several projects in Montreal , this flexibility has made it possible to completely modernize an HVAC system without sacrificing storage space or modifying the building structure.

Constant flow ECM engine: comfort and stability

The ECM constant flow motor automatically adjusts airflow according to the actual conditions of the ductwork. This technology offers several tangible advantages:

• a stable airflow in all rooms,

• a reduction in operating noise,

• improved energy efficiency of the fan.

For the occupants, this translates into more consistent comfort, particularly appreciated in multi-story houses or dwellings with long sections of ductwork.

Simplified maintenance and increased longevity

The modular, sliding evaporator coil greatly simplifies servicing and maintenance. During our service visits, this design allows us to:

• quick access to components

• more effective cleaning

• a reduction in intervention time.

In the long term, this directly contributes to the system's durability and the stability of its performance.

Acoustic comfort adapted to residential environments

The CANAIR 4CDH 's external noise level is particularly well controlled. In dense residential environments, such as certain areas of Longueuil or Laval , this aspect becomes crucial.

Inside, inverter technology allows for smooth and continuous operation, without sudden noises. Customers often report a significant improvement in acoustic comfort, especially at night or during extended heating periods.

A truly optimized add-on solution

The CANAIR 4CDH R-454B | 1.5T "ADD-ON" Central Heat Pump was designed to work efficiently with an existing electric furnace . At AirGreen , every project begins with a complete analysis:

• electrical panel capacity

• condition and design of the ducts,

• actual heating and air conditioning needs.

This approach makes it possible, in many cases in Montreal and on the North Shore , to avoid a complete replacement of the central system. The result: a more targeted, better-controlled investment and a faster return on investment.

LogisVert subsidy: a significant financial lever

This heat pump is eligible for the LogisVert provincial grant , which represents a significant financial advantage. For many homeowners, this assistance allows them to upgrade to a more efficient solution without increasing the overall project budget.

We support our clients at every stage:

• validation of eligibility,

• preparation of required documents,

• complete compliance of the installation.

Guarantees and long-term peace of mind

The CANAIR 4CDH 1.5T comes with a 10-year warranty on the compressor and parts , with the option to add an extended warranty on labor. This level of coverage meets the expectations of customers seeking a reliable, predictable system backed by structured after-sales service.
