GREE FLEXX R32 “ADD-ON” Central Heat Pump | 5T | Case Coil

• BROCHURE

A central heat pump designed for the realities of the Quebec climate

At AirGreen, we work daily with homeowners, building managers, and real estate developers in Montreal , Laval , Longueuil , and on the North and South Shores . One constant theme emerges in almost every discussion: the need for a central system capable of operating reliably in winter without compromising energy efficiency or compatibility with existing infrastructure. The GREE FLEXX R32 | 5T | Case Coil "ADD-ON" Central Heat Pump was specifically developed to meet these very real requirements.

This is not a generic central system. It's a solution designed to integrate seamlessly into existing buildings, sometimes complex ductwork, and established heating habits. In practice, this means fewer structural modifications, improved mechanical consistency, and an HVAC installation project that respects both technical realities and the client's budget.

A real ability to heat efficiently down to -30°C

The most critical aspect for a central heat pump in Quebec remains its ability to provide heating when temperatures become extreme. The GREE FLEXX R32 stands out with a heating operating range that can reach -30°C , a threshold that corresponds to the conditions we regularly encounter during winter, particularly in the more exposed areas of the North Shore and in certain zones of Laval .

For the 5-tonne version (60,000 BTU) , the useful power remains significant even in severe conditions:

• Approximately 40,000 BTU at -8°C

• Up to 54,000 BTU at -15°C

In practical terms, this allows for maintaining a stable indoor temperature in large houses, multi-unit residential buildings, or light commercial buildings, without systematically relying on supplemental heating. In several projects completed by AirGreen in Montreal and Longueuil , this low-temperature performance reduced the use of costly secondary systems while improving occupant comfort.

High-performance central air conditioning for increasingly demanding summers

Beyond heating, the GREE FLEXX R32 5T Central Heat Pump offers a cooling capacity of 60,000 BTU , suitable for large areas and buildings with high heat loads. The prolonged heat waves we now experience every summer require air conditioning capable of operating for extended periods without loss of efficiency.

Thanks to its proper sizing and precise electronic control, this system ensures uniform air distribution, limiting temperature differences between floors. In several family homes on the South Shore , we have observed a significant improvement in comfort, particularly in areas historically difficult to cool, such as upper floors or rooms with large windows.

Measurable energy efficiency and controlled consumption

The seasonal performance of the GREE FLEXX R32 reflects a thoughtful balance between power and efficiency:

• SEER2 greater than 15 , depending on the configuration

• HSPF2 around 9 to 9.5

• EER2 around 11.5

• COP at -8 °C greater than 1.8

These values ​​translate, on the ground, into more stable electricity consumption , even during periods of high demand. For many AirGreen customers in Laval and Montreal , this has meant better predictability of annual energy costs, a particularly important factor in a context of rising rates and increased electrification of buildings.

R-32 refrigerant: a future-proof technical choice

The use of R-32 refrigerant is a key element of this central heat pump. This fluid has a reduced environmental impact compared to previous generations, while offering excellent thermodynamic properties. From a technical standpoint, this allows:

• A lower refrigerant charge

• Better efficiency at equivalent power

• Increased stability during heating and cooling cycles

At AirGreen, we've observed that properly installed R-32 systems offer more precise responsiveness , which improves indoor comfort and reduces premature component wear. For homeowners looking to invest in a sustainable solution that aligns with future HVAC market trends, this choice represents a tangible advantage.

ADD-ON concept: maximum flexibility for existing buildings

The term ADD-ON is central to the philosophy of this model. It refers to an advanced integration capability within existing systems, which corresponds to the majority of projects we undertake at AirGreen. This approach is particularly relevant in the following situations:

• Replacing an old central system without complete reconstruction of the ducts

• Gradual energy modernization of an existing building

• Dual-energy or dual-fuel projects combining different heating sources

• Space constraints in mechanical rooms

Compatibility with 24 VAC thermostats also simplifies integration and, in some cases, allows existing control equipment to be retained. The result: a smoother, less invasive HVAC installation better suited to the realities of the building.

Airflow, dimensions and acoustic comfort

The Case Coil version of the GREE FLEXX R32 5T is designed to deliver an airflow of up to approximately 1,500 CFM , ensuring efficient circulation throughout the ductwork. This airflow is essential for maintaining a consistent temperature in multi-story or multi-zone buildings.

Acoustically, the outdoor unit has a noise level of approximately 62 dB(A) . In the dense urban environments of Montreal and Longueuil , this parameter contributes to better system integration, both for occupants and the neighborhood.

Concrete examples of AirGreen installations

In Laval , we recently installed a GREE FLEXX R32 5T central heat pump in a large residence with a ductwork system that was several decades old. Thanks to the ADD-ON concept, the existing infrastructure could be retained while significantly improving the overall performance of the system. The client noticed an immediate decrease in heating costs during the first winter.

On the South Shore , in a multi-unit residential building, the system's flexibility allowed for precise adjustment of capacity and airflow to the actual needs of the occupants, while respecting the building's electrical limits. This type of project perfectly illustrates the advantages of a central heat pump capable of adapting to diverse contexts without excessive compromises.

Reliability, guarantee and professional approach

The GREE FLEXX R32 Central Heat Pump is covered by an extended warranty on the compressor and parts , offering valuable peace of mind for homeowners. At AirGreen, however, we know that a high-performing system depends first and foremost on the quality of its installation. That's why our certified refrigeration technicians pay particular attention to:

• Precise sizing according to the actual thermal load

• To balance the airflow

• Strict adherence to electrical and mechanical parameters

This rigor helps to preserve the system's performance in the long term and avoids costly adjustments after installation.
