A central heat pump designed for Quebec’s real climate, not theoretical conditions

At AirGreen, we work every day with Quebec’s climate reality: long winters, periods of intense cold, increasingly humid summers, and unpredictable transitional seasons. Installing a central heat pump here is never just about comparing numbers on a spec sheet. It’s about understanding how a system will perform over several years, in an occupied home, with real habits, load variations, and constraints unique to each building.

The Gree FLEXX ULTRA R32 Central Heat Pump – 3 tons fits perfectly within this approach. It is not a product designed solely to show good performance on paper, but a system engineered to operate stably, continuously, and predictably, even when conditions become challenging. This is precisely why we regularly install it in Montreal, Laval, Longueuil, as well as on the South Shore and the North Shore, in single-family homes, plexes, multigenerational houses, and medium-sized residential buildings alike.

The Gree FLEXX ULTRA R32 – 3 tons: a design focused on flexibility and durability

A central architecture suited for smart replacements

A key point sets the FLEXX ULTRA R32 apart from many recent central systems: its compatibility with existing configurations. The system operates with a conventional 24 VAC thermostat, which greatly simplifies replacement projects. In many cases, it is possible to keep:

• Existing ventilation ducts

• The zoning logic already in place

• Certain peripheral components, depending on their condition

At AirGreen, we find that this flexibility not only reduces costs but also shortens installation times and limits risks associated with major HVAC system modifications.

A more modern refrigerant that aligns better with current standards

The choice of R-32 gas is no accident. It offers:

• A lower global warming potential than older refrigerants

• Improved partial load energy efficiency

• Better compliance with current and future environmental regulations

In projects we carry out on the South Shore, notably in Brossard and Saint-Constant, this point is often decisive for owners who want to invest in a durable system without having to consider premature replacement in a few years.

Heating performance: stability that changes the daily experience

Maintaining comfort even at very low temperatures

The FLEXX ULTRA R32 – 3 tons is designed to operate efficiently down to -30 °C, which corresponds to the most demanding conditions encountered in the greater Montreal area. Specifically, this means:

• A nominal capacity of 36,000 BTU

• Power maintained at -8 °C around 28,200 BTU

• A still very high capacity at -15 °C, nearing 34,000 BTU

In several installations carried out in Laval and Terrebonne, we observed that the system continues to heat evenly even during long periods of intense cold, without constantly triggering auxiliary elements.

Even heat distribution

Another often underestimated aspect concerns the quality of thermal distribution. A central heat pump can produce a lot of heat, but if airflow management is poorly balanced, comfort will not be achieved.

With the FLEXX ULTRA R32, the high and stable airflow allows:

• A more uniform temperature between floors

• Fewer cold spots in distant rooms

• A gentler and more consistent feeling of warmth

Clients in Longueuil and Montreal have often told us that the house feels "more stable," without sudden variations, which greatly improves daily comfort.

Air conditioning and dehumidification: better-controlled summer comfort

A concrete response to Quebec humidity

Summers in southern Quebec are marked by high humidity, sometimes more uncomfortable than the heat itself. The dehumidification capacity of about 11.26 pints per hour of the 3-ton version plays a central role here.

In practice, this translates to:

• Drier and more pleasant air

• A reduction in the feeling of heaviness

• An improvement in indoor air quality

During a recent installation in a duplex in Montreal, the owner reported a significant reduction in persistent humidity in the upstairs bedrooms, a problem present for several years with the old system.

Efficient air conditioning without overconsumption

With a cooling capacity of 36,000 BTU, the FLEXX ULTRA R32 – 3 tons is perfectly suited for medium to large residential areas. Its modulating operation avoids short cycles, which improves:

• Energy efficiency

• Acoustic comfort

• Compressor longevity

Noise level, dimensions, and residential integration

Quiet operation for urban environments

In dense neighborhoods of Montreal or Laval, the noise of an outdoor unit is a real issue. With an outdoor noise level around 61 dB(A) and about 51 dB(A) for the indoor unit, the FLEXX ULTRA R32 remains within a comfortable range for a central system of this power.

This discretion facilitates integration:

• In restricted backyards

• Near bedrooms or living spaces

• In multi-unit residential buildings

Dimensions and installation constraints

The compact design of the indoor unit allows installation in technical rooms, basements, or mechanical rooms where space is sometimes limited. At AirGreen, we systematically adapt the layout to preserve accessibility for future maintenance.

HVAC installation: the importance of AirGreen expertise

Rigorous sizing, a key step to success

A 3-ton central heat pump is not universal. Poorly sized, it can cause:

• Insufficient dehumidification

• Unnecessary energy consumption

• Accelerated wear of components

That is why we always perform a detailed thermal analysis before recommending this model. This step is essential to ensure that the FLEXX ULTRA R32 will express its full potential in your specific building.

Installations adapted to every reality

We have installed this system in a wide variety of contexts:

• Replacement of central systems over 15 or 20 years old

• Modernization of houses with existing distribution

• Integration into energy-renovated buildings

Each project benefits from the field experience of our refrigeration technicians and our in-depth knowledge of Gree equipment.

Energy efficiency, subsidies, and long-term investment

Access to provincial subsidies

The Gree FLEXX ULTRA R32 Central Heat Pump – 3 tons is eligible for the LogisVert program, with a subsidy of up to $3,384, depending on current criteria. At AirGreen, we support our clients at every step to ensure a compliant and complete application.

A real impact on energy costs

Thanks to its high efficiency ratings and its ability to maintain power in cold conditions, this system often allows:

• A significant reduction in heating costs

• Better stability of energy bills

• Less dependence on auxiliary heating sources

Over several years, this aspect becomes a determining factor in the overall profitability of the installation.

Why entrust your project to AirGreen

Choosing AirGreen means benefiting from:

• With professional and compliant HVAC installation

• With experienced technicians specialized in central systems

• With $5,000,000 liability insurance
