A central heat pump designed to meet the real needs of Quebec

At AirGreen, we work daily on central HVAC projects in Montreal, Laval, Longueuil, and on both the North and South Shores. Quebec's climate demands precision: systems must provide reliable heating in the depths of winter , stable cooling during heat waves , and effective humidity control during the shoulder seasons. The Gree FLEXX ULTRA R32 – 2-tonne central heat pump perfectly addresses these challenges.

This model was designed to operate in harsh conditions, with a heating range down to -30°C , while maintaining impressive energy efficiency throughout the year. In our field experience, this type of performance isn't just a theoretical argument: it's a key factor for homeowners looking to replace an old central heating system without compromising their comfort in January or February.

The FLEXX ULTRA R32 is suitable for both replacement projects and new constructions, and it is this versatility that makes it a solution that we regularly install in very varied contexts, from single-family homes to multi-unit buildings.

A truly flexible core design, conceived for replacements.

Compatibility with existing systems

One of the major advantages of the Gree FLEXX ULTRA R32 central heat pump is its compatibility with conventional 24 VAC thermostats . In practical terms, this means that in many projects in Montreal and Laval, we can completely upgrade the heating and cooling system without having to replace the entire control infrastructure.

For customers, this translates to:

• Fewer invasive procedures

• A simpler transition to a modern heat pump

• A reduction in costs related to electrical or control modifications

In several replacements carried out by AirGreen on the South Shore, this compatibility made it possible to keep the existing thermostat while benefiting from a latest generation central heat pump.

A solution adapted to existing conduit networks

The FLEXX ULTRA R32 was designed to integrate into existing ductwork systems , provided these are correctly sized and in good condition. Before each installation, we carry out a complete analysis:

• Evaluation of available airflow

• Checking the insulation of the ducts

• Adjusting the registers and the fan

This approach is essential to ensure that the full 24,000 BTU capacity is actually utilized in every room of the building. A high-performance central system that is poorly integrated quickly loses its benefits.

Energy performance and operation under real-world conditions

Heating capacity in cold climates

One of the most important criteria for our customers in Montreal and on the North Shore is heating capacity in extreme cold. The Gree FLEXX ULTRA R32 central heat pump is capable of maintaining stable heat output down to -30°C , making it perfectly suited to Quebec winters.

In several installations carried out by AirGreen, we observed:

• Maintaining comfort during prolonged cold spells

• A reduction in dependence on a backup system

• Improved temperature stability inside

For homeowners accustomed to systems that quickly lost efficiency below -15°C, the difference is noticeable from the first winter.

Efficient and constant air conditioning

In cooling mode, the 24,000 BTU capacity effectively cools average-sized homes, even during periods of intense heat in Montreal or the Montérégie region. The system modulates its power to avoid excessively short cycles, improving both comfort and the lifespan of the components.

This modulation also contributes to better humidity management , an aspect often overlooked but essential for summer comfort.

Dehumidification and air quality

With a dehumidification capacity of approximately 7.73 pints per hour , the Gree FLEXX ULTRA R32 central heat pump plays an active role in controlling indoor humidity. In areas like Longueuil or certain neighborhoods in Montreal where humidity can become uncomfortable in the summer, this feature significantly improves quality of life.

Several customers have reported a feeling of increased comfort, even at slightly higher temperatures, simply because the air was better dehumidified.

The choice of R-32 refrigerant: a well-considered technical shift

Switching to R-32 is not just a matter of environmental compliance. In practice, this refrigerant allows for:

• Improved thermodynamic efficiency

• A lower fluid charge

• Stable performance over a wide operating range

At AirGreen, we are supporting more and more customers who want to modernize their HVAC system while taking these aspects into account, without sacrificing reliability or performance in cold climates.

Acoustic comfort and residential integration

The noise levels of the Gree FLEXX ULTRA R32 central heat pump are compatible with dense residential environments:

• Approximately 50 dB(A) for the indoor unit

• Approximately 60 dB(A) for the outdoor unit

During installation, we pay particular attention to the placement of the outdoor unit, especially in urban areas of Montreal or Laval where proximity to neighbors requires a thoughtful approach. Proper placement contributes to both comfort and compliance with municipal regulations.

AirGreen Case Study: Real-World Installation on the South Shore

In a recent project in Boucherville, AirGreen replaced an old central system combining gas heating and aging air conditioning with a Gree FLEXX ULTRA R32 – 2 tonne central heat pump .
The client's objectives were clear:

• Reduce energy consumption

• Maintaining optimal comfort in winter

• Take advantage of available subsidies

After a complete thermal analysis, the installation enabled:

• A measurable reduction in energy costs

• Stable comfort even at temperatures below -25°C

• A smooth transition to a fully electric system

This type of project perfectly illustrates the relevance of the FLEXX ULTRA R32 for Quebec residences.

Installation: the details that make the difference

A high-performance central heat pump only delivers its full potential if the installation is flawless. At AirGreen, we emphasize:

• The precise sizing of the system

• Compliance with pipe lengths and heights

• Adjusting the airflow according to the building configuration

• A complete and documented commissioning

These steps are essential to ensure the longevity of the system, the stability of performance and compliance with warranty conditions.

Maintenance, reliability and long-term durability

The Gree FLEXX ULTRA R32 central heat pump is built to last, but like any HVAC system, it requires regular maintenance . We recommend annual maintenance including:

• Inspection of mechanical components

• Heat exchanger cleaning

• Pressure and yield check

In our experience in Montreal and on the North Shore, rigorous maintenance not only prevents costly breakdowns, but also maintains a consistent level of performance year after year.
