• Official Brochure: ENGLISH

A central heat pump designed for Quebec winters, existing buildings, and real-world site requirements.

At AirGreen , we install central HVAC systems in very specific conditions: existing buildings, sometimes older, imperfect ductwork, real electrical constraints, and high expectations for comfort and controlled costs. The GREE UNIX R32 – 2-tonne (24,000 BTU) central heat pump is among the systems that best meet these realities, particularly in Montreal , Laval , Longueuil , and on the North and South Shores .

This model was not developed as a simple alternative to traditional systems: it is a true central heat pump with high winter capacity , capable of providing primary heating for a building even when the outside temperature drops to -30°C . This is precisely what sets it apart in practice.

A central design conceived for smart renovation and replacement

A truly flexible central system

The GREE UNIX R32 stands out for its flexible integration . It can be installed:

• with a dedicated ventilation cabinet ,

• retrofitting with an existing furnace (electric, gas or dual-energy),

• with a coil in a box when the objective is to replace only the heat pump part.

In practice, this allows AirGreen to offer solutions tailored to single-family homes, duplexes, triplexes, as well as multi-unit residential buildings and light commercial buildings. In Laval , for example, we often deal with houses built in the 1980s and 1990s: the GREE UNIX R32 allows us to modernize the system without completely redoing the air distribution, which significantly reduces costs and time.

A key advantage in renovation

Many homeowners hesitate to switch to a central heat pump for fear of major renovations. The possibility of retrofitting is a key factor here. In several projects completed by AirGreen in Brossard and Repentigny , this approach allowed them to keep their existing furnace as supplemental heating while benefiting from a modern, efficient central system that qualifies for subsidies.

Reliable central heating down to -30°C: a requirement, not a luxury

A truly usable winter performance

Quebec's climate leaves no room for error. The GREE UNIX R32 central heat pump is designed to operate down to -30°C , with remarkable stability thanks to:

• a two-stage, two-cylinder compressor ,

• DC Inverter technology , which continuously adjusts the power,

• intelligent management of defrost cycles.

In practical terms, this means fewer temperature fluctuations, more consistent comfort, and reduced use of supplemental heating. At several AirGreen installations on the North Shore , customers have found that their system provides the majority of their annual heating needs, even during prolonged cold spells.

Measured and constant heating power

For this 2-tonne model, the power is clearly defined:

• 24,000 BTU nominal

• 20,600 BTU at -8°C

• 24,000 BTU at -15°C

These figures are particularly important during the sizing process. At AirGreen, we always emphasize rigorous thermal analysis , because an incorrectly sized central heat pump, even a high-performing one, will never deliver the expected results.

Efficient and stable central air conditioning during heat waves

Consistent summer comfort

In cooling mode, the 24,000 BTU capacity allows for the efficient cooling of large areas, including multi-story buildings. Unlike some systems that quickly lose efficiency in high temperatures, the GREE UNIX R32 maintains 100% of its cooling capacity up to 46°C .

In densely built-up urban neighborhoods of Montreal , where heat accumulates quickly, this stability is a real advantage. Occupants benefit from a constant temperature, without hot or cold spots.

Energy efficiency: concrete figures, not vague promises

Key performance indicators

The GREE UNIX R32 – 2-tonne central heat pump delivers solid performance:

• SEER2: 18.0

• HSPF2: 10.0

• EER2: 12.5

• COP at -8 °C: 12.03

These values ​​translate directly into optimized energy consumption , particularly for heating, where demand is highest in Quebec. In several AirGreen projects in Longueuil , clients have seen a tangible decrease in their annual bills, without compromising comfort.

ENERGY STAR® Cold Climate Certification

The ENERGY STAR® certification – cold climate – confirms that this system meets the strictest criteria for northern regions. It is also a determining factor for eligibility for financial assistance programs.

Dehumidification: an often overlooked but essential aspect

The dehumidification capacity of 7.73 pints/h plays a key role in indoor comfort. Good dehumidification allows for:

• to reduce the sensation of heat at the same temperature,

• to improve air quality,

• to protect interior materials and furniture.

In well-insulated homes or newer buildings on the South Shore , we frequently find that humidity control is just as important as air conditioning itself. The GREE UNIX R32 addresses this challenge very well.

R32 refrigerant: efficiency and environmental responsibility

The choice of R32 represents a significant evolution in the field of central HVAC . This refrigerant offers:

• a reduced environmental impact compared to previous generations,

• improved thermodynamic efficiency

• a lower load for equivalent performance.

For AirGreen, this is a consistent choice: to improve energy performance while respecting current environmental standards, without compromising long-term reliability.

Acoustic comfort and discreet integration

With an indoor noise level of approximately 50 dB(A) and an outdoor noise level of 60 dB(A) , the GREE UNIX R32 central heat pump remains quiet, even in close-knit residential environments. During our installations in Rosemont , Ahuntsic , and Saint-Lambert , we pay particular attention to the positioning of the outdoor unit, the insulation of the ducts, and the use of anti-vibration mounts to optimize acoustic comfort.

System control, compatibility and scalability

Compatibility with standard 24 VAC thermostats is a major advantage. It allows:

• to keep an existing thermostat,

• to opt for more advanced control,

• to add WiFi connectivity if desired.

This flexibility simplifies the integration of the system into existing buildings and reduces indirect costs associated with the unnecessary replacement of functional equipment.

LogisVert subsidy and AirGreen turnkey support

This model is eligible for a provincial LogisVert grant of up to $2,472 , depending on the configuration and building. At AirGreen , we don't just install the equipment:

• We verify eligibility before work begins.

• We are preparing the required documents.

• We support the client until the final deposit.

This approach avoids unpleasant surprises and allows clients in Montreal , Laval and Longueuil to maximize their investment.

Why AirGreen recommends the GREE UNIX R32 – 2 tonnes

Our recommendation is based on field experience, not just technical specifications. This system is distinguished by:

• its reliability in heating during extreme cold ,

• its flexibility for installation during renovations ,

• its balance between performance, cost and sustainability ,

• its adaptation to the realities of Quebec buildings.

This is a central heat pump that we install with complete confidence, in both residential and light commercial projects.

Discuss your HVAC project with AirGreen

Each building has its own specific characteristics: surface area, insulation, ductwork, and energy consumption patterns. A central heat pump must be carefully selected and installed to ensure optimal performance.
