GREE FLEXX R410A “ADD-ON” Central Heat Pump | 3T - Cased Coil

• BROCHURE IN

A central heat pump designed for the actual climatic conditions of Quebec

At AirGreen , we have been installing, analyzing, and optimizing central HVAC systems for over fifteen years throughout Greater Montreal, Laval, Longueuil, the North Shore , and the South Shore . Our field experience has taught us one essential thing: a central system that performs well on paper is only truly effective if it is adapted to the climate, the building, and the actual usage of the occupants .

The GREE FLEXX R410A | 3T - Cased Coil "ADD-ON" Central Heat Pump is one of the few models that meet these three requirements simultaneously. It has been designed to operate stably, efficiently, and durably in severe winter conditions , while remaining perfectly suited to renovation or energy conversion projects where a ductwork system already exists.

In many projects completed by AirGreen in Montreal and on the South Shore, this heat pump has allowed homeowners to modernize their central system without replacing everything , significantly reducing their operating costs and improving the overall comfort of the home.

Heating and cooling performance: measurable stability

Power output adapted to Quebec homes

With a nominal cooling capacity of 36,000 BTU (3 tonnes) , this model is ideal for:

• medium to large-sized single-family homes,

• well-insulated duplexes and triplexes,

• residences with multiple floors and heated basements,

• buildings where central air distribution is already in place.

In heating mode, the GREE FLEXX ADD-ON clearly stands out from many standard central heat pumps. It is capable of maintaining efficient heat production down to -30°C , a crucial factor for the climate of Montreal and Laval.

In practice, this translates to:

• 29,000 BTU at -8°C

• 28,000 BTU at -15°C

• stable performance during long periods of continuous cold

For our North Shore customers, this means that the heat pump remains the primary source of heating for most of the winter, greatly limiting the use of an existing or electric backup system.

Energy efficiency and real savings

Energy efficiency isn't just a number: it directly impacts your electricity bill, thermal stability, and system durability. This heat pump delivers solid and consistent performance.

• SEER2: 16.0

• HSPF2: 9.0

• EER2: 10.0

• COP of 11.83 at -8 °C

• ENERGY STAR® Certification

• ENERGY STAR® Certification – Cold Climate

In several AirGreen installations in Longueuil and Boucherville, these features have made it possible to significantly reduce annual heating consumption , while ensuring constant comfort, even during prolonged cold spells.

Inverter technology: continuous comfort and reduced wear

Intelligent power modulation

The GREE FLEXX series is equipped with variable-speed inverter technology , a key element for indoor comfort. Unlike older central systems that operate in abrupt cycles, this compressor continuously adjusts its power according to the building's actual needs.

The benefits observed on the ground are numerous:

• more stable temperature in all rooms,

• elimination of sudden temperature fluctuations,

• noise reduction related to frequent starts,

• reduction in electricity consumption during intermediate periods.

In multi-story houses in Montreal, this modulation helps to avoid temperature differences between the ground floor and the upper floor, a common problem with traditional central systems.

Add-on configuration with Cased Coil: an ideal solution for renovations

Integration with existing network

The ADD-ON configuration with Cased Coil is designed to integrate seamlessly with an existing core system. It is particularly relevant when:

• The pipes are in good condition.

• An old heating system must be retained as a backup.

• The client wants to reduce transformation costs.

• Priority is given to energy efficiency.

Thanks to 24V communication , standard 3/8 – 3/4 piping and a 220V power supply, integration is done cleanly, without major structural modifications.

At AirGreen, we often use this model in modernization projects in Laval and on the South Shore, where it would make little sense to replace the entire network to achieve excellent performance.

Acoustic comfort and discretion in everyday life

A silent central system

With an outdoor sound pressure level of approximately 52 dB(A) , this heat pump is among the quietest central options in its class. In dense residential areas of Montreal or on smaller lots, this feature is far from insignificant.

Inside, the modulated airflow (up to 1,500 CFM ) allows for uniform distribution without excessive noise in the grilles, provided that the sizing is rigorous — a point that we systematically validate during our HVAC installations.

Dimensions designed for flexibility

• Outdoor unit : 32.25 x 18.125 x 37 in

• Indoor Unit (Cased Coil) : 17.5 x 21.25 x 23 in

These dimensions facilitate installation in confined mechanical spaces, particularly in converted basements, existing mechanical rooms or partial replacement projects.

Dehumidification, air quality and overall comfort

The dehumidification capacity of 9.68 pt/h directly contributes to summer comfort. During periods of high humidity, particularly in Montreal and Longueuil, this function helps maintain a more stable indoor humidity level, reducing the feeling of heaviness and improving ambient air quality.

Combined with good balancing of the ductwork, this feature significantly improves perceived comfort, even on hot and humid days.

Reliability, guarantees and intelligent control

A solid foundation for long-term investment

The 12-year warranty on the compressor and parts reflects the robustness of the design. Depending on the project and configuration chosen, an additional warranty can be added to ensure maximum peace of mind.

At AirGreen, we take the time to clearly explain the warranty conditions, limitations and best maintenance practices to ensure the longevity of the system.

Wi-Fi control option

The system is compatible with an optional Wi-Fi thermostat , allowing:

• remote control,

• precise programming

• better daily energy management.

In several recent projects in Laval, this option has allowed owners to optimize their consumption without compromising on comfort.

LogisVert subsidy and overall profitability

This heat pump is eligible for the LogisVert provincial subsidy , with an amount of up to $3,480 depending on the applicable criteria. For many customers, this financial assistance plays a decisive role in their investment decision.

At AirGreen, we support our clients in validating eligibility , preparing documents and optimizing the configuration to maximize return on investment.

Why AirGreen recommends this model

The GREE FLEXX R410A | 3T - Cased Coil "ADD-ON" Central Heat Pump is not a generic choice. It's a solution we recommend when:

• The cold climate is a key factor.

• Stability of the heating system is a priority.

• a network of conduits already exists,

• Energy efficiency and long-term reliability are essential.

Our experience in Montreal, Laval, Longueuil, on the North Shore and the South Shore demonstrates that this model offers a remarkable balance between performance, flexibility and controlled costs , provided that it is properly sized and installed.
