A specialized HVAC solution for spaces where every detail matters

In many residential , commercial , and multi-unit projects in Montreal , Laval , Longueuil , on the North Shore and the South Shore , the challenge is not simply to heat or cool a space. It is about doing so without compromising the architecture , without creating localized discomfort , and without multiplying visible equipment .
The GREE CROSSOVER R32 1-Way Cassette Heat Pump | 12000 BTU precisely meets these types of requirements.

At AirGreen , we integrate this model into projects where a traditional wall-mounted heat pump would be either unsuitable or aesthetically problematic. Modern condos, professional offices, clinics, narrow retail spaces, circulation areas, or spaces with large windows: this 1-way cassette allows for controlled, directional, and discreet air distribution directly to the ceiling.

Unlike more generic solutions, this type of device requires careful planning beforehand . This is precisely where our field experience makes the difference.

Understanding the actual use of a 1-track cassette

A common mistake is to consider a 1-way cassette as simply a ceiling-mounted equivalent of a wall unit. In practice, it is a specialized HVAC tool , designed for very specific scenarios.

This model is particularly relevant when:

• the walls must remain clear (furniture, display cases, workstations, fixed equipment);

• air diffusion should be directed in a single direction , rather than distributed in all directions;

• The space requires a virtually invisible solution, integrated into the ceiling;

• Acoustic comfort is a priority;

• The service area is clearly defined.

In Montreal , we installed this cassette in glass-fronted offices where controlled horizontal airflow neutralized the cold wall effect in winter. On the South Shore , it was used in linear retail spaces where the air needed to flow with customer traffic without creating drafts.

Thermal performance: what the numbers really mean

Capacity and stability in real-world conditions

• Cooling capacity : 12,000 BTU

• Heating capacity down to -30°C

• Rated power : 12,000 BTU

• Power output maintained at -8°C : approximately 10,000 BTU

This data is important, but its interpretation is even more so.
In the reality of the Quebec climate, this cassette is perfectly suited for well-sized areas , properly insulated and integrated into a coherent HVAC project.

During our assessments in Laval and Longueuil , we consistently emphasize the importance of accurately calculating the thermal load . Installing this model in a space that is too large or poorly insulated inevitably leads to unrealistic expectations. Conversely, when properly sized, its thermal stability is remarkable, even during periods of intense cold.

Energy efficiency and choice of R-32 refrigerant

The use of R-32 gas offers a tangible advantage on several levels:

• improved heat transfer efficiency;

• reduced refrigerant charge;

• lower environmental impact compared to previous generations;

• compatibility with current and future regulatory requirements.

For many of our clients in Montreal and on the North Shore , this choice is part of an approach to reducing the overall energy footprint of the building, even in the absence of specific subsidies.

Dehumidification and seasonal comfort

With a dehumidification capacity of 2.96 pints/h , this cassette actively contributes to summer comfort. In urban offices and condos, this helps maintain a consistently cool feeling without the need for excessive air conditioning.

Air diffusion and acoustic comfort: an often underestimated point

One of the major advantages of this cassette lies in the precise management of airflow . Controlling the orientation of the louvers allows the diffusion to be adapted according to the actual occupancy of the space.

In several installations carried out by AirGreen:

• we avoided direct air currents on fixed workstations;

• we directed the airflow towards glazed areas to counteract heat loss;

• We have improved temperature homogeneity in confined spaces.

Indoor noise levels , particularly at low and medium speeds, are a major asset in professional environments. In a practice located in Longueuil , reducing perceived noise was a determining factor in client satisfaction.

Installation: where everything really happens

Ceiling integration and technical constraints

Installing a 1-channel cassette requires a rigorous analysis:

• Available ceiling height;

• future access for maintenance;

• condensate management;

• aesthetic integration with the existing grid and finishes.

The internal condensate pump , combined with a float switch safety system, significantly reduces risks, provided the drainage network is properly designed. We have seen too many projects where this step was neglected, leading to costly interventions later on.

Electricity and compliance

• Voltage : 220 V

• Minimum ampacity (MCA) : 11 A

• Maximum protection (MOP) : 15 A

In several older residences in Montreal , electrical panel upgrades were necessary. Anticipating these adjustments during the assessment phase helps avoid delays, additional costs, and compromises on safety.

Indoor/outdoor association

• Indoor unit : GKH(12)DA-D6DNA1B/I

• Outdoor unit : GWH12AGCXD-D6DNA4D/O

• AHRI : 216618213

The balance between the two units is essential. An incorrect combination, even with a similar BTU, can reduce efficiency, increase consumption, and shorten the compressor's lifespan.

Common mistakes observed in the market

Thanks to site reviews and diagnostics carried out by our teams, certain errors recur regularly:

• oversizing leading to short cycles;

• poor airflow direction;

• absence of serious thermal calculations;

• maintenance access forgotten;

• unrealistic expectations regarding surface coverage.

These errors are not related to the product itself, but to a misunderstanding of its use . This is precisely what we at AirGreen aim to avoid.

Guarantee, reliability and continuity of service

• Compressor warranty : 10 years

• Parts warranty : 10 years

• Labor : 0 years (extension possible)

For commercial or multi-residential projects in Laval and on the South Shore , we often recommend an additional guarantee to ensure long-term peace of mind and optimal continuity of service.

Why AirGreen stands out from this type of product

We never offer a 1-channel cassette by default. At AirGreen, this model is only recommended when it is the most technically logical solution .

Our approach is based on:

• an in-depth analysis of the space and its actual use;

• concrete examples of successful installations in Montreal , Laval and Longueuil ;

• refrigeration technicians experienced with ceiling-mounted systems;

• complete transparency regarding the limitations and benefits of the product.

This methodology helps to avoid compromises and ensures lasting comfort, season after season.
