GREE FLEXX R32 “ADD-ON” Central Heat Pump | 2T | Case Coil

• BROCHURE

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

At AirGreen , our approach to HVAC installation is based on a simple reality: in Quebec, a central system must operate without compromise , whether during summer heat waves or periods of extreme cold. The GREE FLEXX R32 | 2T | Case Coil "ADD-ON" Central Heat Pump was designed specifically for this context. It is not a generic product, but a coherent technical solution for residential buildings that demand thermal stability, energy efficiency, and intelligent integration with existing systems .

In our daily practice in Montreal , Laval , Longueuil , on the North Shore and the South Shore , this model stands out for its ability to adapt to a multitude of real-world scenarios: houses with still-functional electric furnaces, aging central systems without air conditioning, or gradual energy modernization projects.

The ADD-ON principle: optimize without destroying everything

The ADD-ON concept is often misunderstood. It is not a temporary solution or a technical compromise. On the contrary, it is a strategic approach that allows for significant improvements in comfort and energy performance , while retaining existing, still-relevant equipment.

In many homes in Laval and Boucherville , we encounter homeowners who have ductwork in excellent condition and a reliable, but costly, heating source. Installing a GREE FLEXX R32 central heat pump in an ADD-ON configuration then allows you to:

• to immediately reduce annual energy consumption

• to add a high-performance central air conditioning system

• to limit wear and tear on the main heating system

• to maintain an effective backup source for extreme cold

• to improve the overall value of the building

In a recent project in Longueuil , a single-family home heated solely by electricity was consuming excessive amounts of energy in winter. The addition of this 2-tonne / 24,000 BTU central heat pump stabilized the temperature on two floors, while reducing energy bills from the very first heating season.

Real performance on the field, not just on paper

The GREE FLEXX R32 – 2T stands out for a rare combination: constant power, extended operating range and stable performance , even when the temperature drops sharply.

Heating and air conditioning adapted to the Nordic climate

• Rated capacity : 24,000 BTU

• Guaranteed heating down to -30°C

• Power at -15°C : 24,000 BTU

• Power at -8°C : 15,000 BTU

This data translates into a system capable of providing a significant portion of the heating needs for most of the Quebec winter. In several installations on the North Shore , we observed a significant reduction in the activation of supplemental heating, even during prolonged periods below -10°C.

Consistent and measurable energy efficiency

• High SEER2 for efficient central air conditioning in summer

• HSPF2 optimized for seasonal heating

• EER2 stable, even under conditions of high demand

• High COP at low temperatures

These indicators explain why this system meets ENERGY STAR® criteria, including for cold climates. For homeowners, this translates into real and predictable savings, rather than theoretical promises.

R-32 refrigerant: a future-proof technical choice

The choice of R-32 is not insignificant. At AirGreen, we favor this refrigerant for very specific reasons:

• Reduced environmental impact compared to previous generations

• Better energy efficiency , requiring less load

• More stable heat transfer , especially in heating

• Better compatibility with upcoming standards

In a context where regulations are evolving rapidly, investing in a central heat pump operating on R-32 helps to avoid premature obsolescence and to protect your investment in the long term.

Well-thought-out mechanical and acoustic integration

The outdoor unit of the 2-tonne version has a balanced design that facilitates its installation on typical residential properties. Its noise level of approximately 60 dB(A) allows for installation near outdoor living spaces without creating excessive disturbance.

Inside, the Case Coil FXA24C32AH integrates easily into existing conduit systems. During installation, our teams pay particular attention to:

• static pressure

• the actual airflow

• the tightness of the fittings

• balancing the areas served

These adjustments, often overlooked, are nevertheless essential to ensure consistent comfort and optimal performance over several years.

LogisVert subsidy: a concrete financial lever

The GREE FLEXX R32 | 2T | Case Coil "ADD-ON" Central Heat Pump is eligible for a $1,800 LogisVert provincial grant . In numerous projects in Montreal and Laval , this financial assistance has made the project immediately profitable.

At AirGreen, we don't just install the equipment. We support our clients every step of the way:

• validation of eligibility

• technical conformity of the installation

• documentation required for the application

• post-installation follow-up

This approach avoids grant rejections and unnecessary delays.

The AirGreen installation: method, precision and consistency

Installing an ADD-ON central heat pump requires much more than a simple connection. A common mistake we often correct is incorrect sizing or ignorance of existing electrical constraints.

Before each installation, our certified refrigeration technicians assess:

• available electrical capacity

• protection parameters ( MCA, MOP )

• the actual length of the piping

• the compatibility of the 24 VAC thermostat

On the South Shore , several clients contacted us after poorly executed installations by other contractors. In these cases, a complete rebalancing and adjustment restored the expected performance.

Reliability and long-term guarantees

The GREE FLEXX R32 comes with a 12-year warranty on the compressor and parts , with the possibility of extensions depending on the circumstances. For a centralized system, this protection is essential: it reflects the manufacturer's confidence and safeguards the owner's investment.

Why AirGreen frequently recommends this model

This central heat pump is not universal, but it perfectly matches a profile that is very common in Quebec: a house with existing ducts, a heating system that is still functional and a clear objective of reducing energy costs.

We particularly recommend it for:

• single-family homes

• duplex and triplex

• projects for gradual modernization

• owners seeking performance, stability and flexibility
