A robust and consistent central solution for buildings with high energy requirements

At AirGreen Air Conditioning & Heating , we have been installing and analyzing central HVAC systems for over 15 years in Montreal , Laval , Longueuil , and on the North and South Shores. The GREE UNIX R32 central heat pump – 5 tons – 60,000 BTU – is one of the systems we recommend when needs exceed typical residential standards and require a stable, measurable, and long-lasting solution.

This model was not designed to meet a simple, one-off air conditioning need. It is intended for large buildings, multi-generational residences, multi-unit residential buildings, as well as light commercial buildings where consistent heating, humidity control, and winter reliability are non-negotiable criteria.

A design conceived for the climatic realities of Quebec

Reliable heating during long winters

In Greater Montreal, central HVAC systems are subjected to particularly demanding conditions: prolonged periods below freezing, frequent restarts, prevailing winds, and rapid temperature fluctuations. The GREE UNIX R32 was developed to maintain its performance even when conditions become critical.

• Functional heating down to -30°C

• Maintaining full heating capacity at -20°C

• Thermal stability without constant dependence on supplementary heating

In our projects carried out in Laval-Ouest , Boucherville and Saint-Eustache , this stable behavior in periods of extreme cold helps to avoid the drops in indoor temperature often observed with more traditional central systems.

Detailed technical specifications – 5-tonne version

Thermal and energy capacities

The 5-tonne (60,000 BTU) version of the UNIX R32 range is distinguished by a precise balance between power, modulation and seasonal efficiency:

• Rated power : 60,000 BTU

• Heating capacity at -8°C : 45,000 BTU

• Heating capacity at -15°C : 54,000 BTU

• SEER2 : 18.5

• HSPF2 : 10.5

• EER2 : 11.7

• COP at -8 °C : 3.40

These values ​​are not abstract: they translate into better controlled electricity consumption during long heating seasons, particularly in buildings where the central system operates for several months a year without prolonged interruption.

Real and measurable dehumidification

An aspect often underestimated in central systems

Dehumidification is a major challenge in well-insulated buildings, especially during the summer and shoulder seasons. The GREE UNIX R32 – 5 tonnes offers a dehumidification capacity of 17.22 pints per hour .

In several projects carried out in Longueuil and Saint-Bruno-de-Montarville , this capacity has enabled:

• To reduce the feeling of inner heaviness during the summer period

• To limit condensation in basements and poorly ventilated areas

• To improve comfort without unnecessarily overcooling the spaces

This is a tangible benefit for families, rental properties, and buildings where indoor humidity is difficult to control with a simple central air conditioner.

DC Inverter technology and two-stage compressor

Continuous modulation adapted to actual demand

The DC Inverter technology integrated into the GREE UNIX R32 continuously adjusts the compressor speed according to the building's actual heating and cooling needs. Unlike binary (on/off) systems, this modulation allows for:

• A more stable indoor temperature

• A reduction in aggressive cycles

• Slower mechanical wear of the components

The two-stage, two-cylinder compressor plays a central role in this precise regulation. In practice, we observe improved comfort consistency, particularly in large homes in Montreal North or on the North Shore , where load variations are frequent between day and night.

Installation flexibility: a real advantage in renovation

Adaptation to existing systems

A major strength of the GREE UNIX R32 is its ability to integrate intelligently into existing installations:

• Compatible with standard 24 VAC thermostats

• Advanced RS485 communication capability

• Installation with dedicated ventilation cabinet , boxed coil or existing furnace

• Compatibility with downstream configurations

In renovation projects in Ahuntsic , Anjou and Châteauguay , this flexibility made it possible to retain part of the conduit network and significantly reduce structural work, while improving the overall performance of the system.

Controlled acoustic comfort for a high-capacity system

Despite its high power, the GREE UNIX R32 – 5 tonnes remains relatively discreet for a central system of this category:

• Indoor unit : 53 dB(A)

• Outdoor unit : 62 dB(A)

In dense residential environments or commercial buildings in urban areas, this feature helps to preserve the quality of life of the occupants and the neighborhood.

R-32 refrigerant: energy efficiency and current compliance

The choice of R-32 refrigerant offers both technical and environmental advantages:

• Improved energy efficiency compared to previous generations

• Lower charge quantity for the same capacity

• Reduced environmental impact

• Compatibility with current and future standards

For owners wishing to invest in a sustainable long-term solution, this choice limits the risks of regulatory obsolescence.

LogisVert subsidy and energy compliance

The GREE UNIX R32 – 5-tonne central heat pump meets the criteria of current energy efficiency programs:

• ENERGY STAR® Certification

• ENERGY STAR® Cold Climate Certification

• Eligibility for the LogisVert grant of up to $5,400

• Recognized and compliant AHRI number

At AirGreen , we systematically support our clients in preparing grant applications to avoid rejections related to technical or administrative details or inadequate configuration.

Concrete examples of AirGreen installations

Multi-unit residential building in Laval

Replacement of an old, energy-intensive central system with a 5-ton GREE UNIX R32 . Results observed after the first full season:

• Significant reduction in electricity consumption

• Uniform temperature between floors

• Reduction in complaints related to thermal comfort

Intergenerational residence on the South Shore

Installation with boxed coils and existing ductwork. Increased dehumidification resolved persistent humidity problems in the basement and common areas.

Common mistakes to avoid with a 5-tonne central system

Systems of this power demand a rigorous approach.

• Oversizing without accurate thermal load calculation

• Undersized or poorly balanced duct network

• Incorrect thermostat selection

• No adjustments were made after commissioning.

At AirGreen , each project begins with a detailed thermal analysis , followed by a design adapted to the actual use of the building.
