Installation of a GREE All Match Slim Duct R32 Ducted System in Boucherville: Slim Duct System Integrated into Ducts in a Technical Attic

A GREE ducted installation designed for invisible comfort on the South Shore

In Boucherville, this AirGreen project highlights a type of HVAC installation that requires much more than a simple equipment replacement: the integration of a GREE ducted heat pump in a restricted attic space, connected to a duct network, optimizing airflow and carefully sealing joints. This project is exactly for homeowners seeking stable comfort in multiple rooms without having a visible wall unit in their interior decor.

The installed system is part of the GREE Ducted – Slim Duct – Ductable family, including the GREE All Match Slim Duct R32 solutions and the GREE ducted low or high static pressure duct models. This type of unit is designed to be hidden in a ceiling, false ceiling, or attic, then connected to ducts that distribute air to targeted rooms. In a house in Boucherville, where interior aesthetics, silence, and even temperature distribution are often priorities, this choice offers a very coherent solution.

On this site, the working environment was particularly technical: blown insulation, sloped framing, insulated flexible ducts, metal plenum, aluminum tape, limited access, and tight space around connections. In this context, every detail counts. A poorly sealed joint, an overly compressed duct, or a too abrupt transition can reduce airflow, increase noise, and harm the overall system performance. That’s why our refrigeration technicians paid special attention to duct continuity, airtightness, and the quality of the connection between rigid and flexible sections.

Why choose a ducted system rather than a classic wall unit

A wall air conditioner or a wall-mounted heat pump remains an excellent solution in many homes. However, for some projects, especially when the client wants to cool or heat multiple rooms without multiplying visible units, the ducted system becomes a much more interesting option.

In this installation in Boucherville, the goal was clear: to achieve a more discreet, more uniform air distribution better integrated into the home's architecture. The client wanted to avoid the appearance of a wall unit in the main areas while benefiting from a system capable of supplying rooms through diffusion grilles.

The ducted system notably allows:

• a more discreet interior appearance, with only grilles visible;
• air distribution adapted to multiple zones;
• better integration in high-end renovations;
• a quieter operation when the system is well designed;
• a flexible solution for houses with attic or drop ceiling available.

This type of project, however, requires a more rigorous design than a standard wall installation. The machine is only part of the solution. The ducts, air returns, transitions, grilles, insulation, and static pressure all play an essential role.

The GREE Ducted range offered by AirGreen

AirGreen offers several GREE Ducted solutions suitable for houses and buildings in Montreal, Laval, Longueuil, the North Shore, and the South Shore. The range notably includes units of 9,000 BTU, 12,000 BTU, 18,000 BTU, 21,000 BTU, 24,000 BTU, 30,000 BTU, and 36,000 BTU, depending on the building's needs and the chosen configuration.

In residential installations, capacity selection is never limited to the area. For a Slim Duct system, we also analyze:

• the number of rooms to serve;
• the total length of the ducts;
• the required static pressure;
• the available height in the attic or ceiling;
• the building insulation;
• the windows and solar orientation;
• the desired noise level;
• the feasibility of access for HVAC maintenance.

The GREE All Match Slim Duct R32 models are particularly interesting for projects where you want to combine performance, compact size, and discreet integration. The refrigerant R32, present in some recent models, belongs to a more current generation of equipment. Depending on the chosen combination, some GREE systems can also be associated with an Energy Star certification and performance designed for Quebec’s winter conditions, with models capable of operating down to -30 °C depending on the series and application.

Low static pressure or high static pressure: a crucial decision

An important part of AirGreen’s work is determining whether the project requires a ducted unit with low static pressure or high static pressure.

Low static pressure may be suitable when the network is short, simple, and minimally restrictive. For example, a small, well-aligned duct run with few outlets and few bends can operate efficiently with a more compact solution.

High static pressure becomes more appropriate when the air must travel a longer distance, supply multiple grilles, or pass through more complex transitions. In an attic like this project, where the ducts must navigate around the structure and adapt to the available space, this analysis is essential.

A poor choice at this stage can lead to very concrete problems: too low airflow in a bedroom, excessive air noise near a grille, shorter cycles, uneven temperature, or performance below expectations. At AirGreen, we validate the project before installation to choose a configuration truly suited to the building.

An attic site where precision makes all the difference

The image of the site clearly shows the reality of a ducted installation: the space is tight, visibility is limited, insulation is present around the work areas, and the ducts must be handled without being crushed. This is not an environment where you can improvise.

Our technicians worked around a metal plenum and insulated ducts, paying particular attention to sealing the joints. The metal tape used on the connections plays an important role in airtightness. An air leak in an attic can quickly become costly, as heated or cooled air is lost in an unoccupied space instead of being delivered to the rooms.

In a ducted system project, we also monitor condensation. When cold air circulates in a warm attic, proper insulation and good control of joints reduce the risk of moisture on surfaces. That is why the choice of ducts, the quality of transitions, and the protection of joints are as important as the connection of the unit itself.

The role of the plenum and transitions in the final comfort

The plenum is a central part of the network. It receives or distributes air depending on the configuration, and it must be designed to reduce unnecessary losses. A poorly sized transition can create turbulence, noise, and poor flow distribution.

In this installation in Boucherville, the connection between the metal box and the insulated flexible ducts had to be done neatly to maintain a constant flow. This work is hardly visible once the installation is complete, but it directly influences the comfort experienced by the client.

A good network must allow air to circulate with as little resistance as possible. This means that ducts must be properly stretched, curves must be smooth, joints must be well sealed, and outlets must be positioned according to the actual use of the rooms.

The tangible benefits of a well-executed ducted HVAC installation in Boucherville

More uniform comfort throughout the house

One of the major advantages of a ducted heat pump is the ability to better distribute heating and cooling. Rather than concentrating air in a single room, the duct network delivers air where it is needed.

For a home in Boucherville, this solution can be especially appreciated in bedrooms, hallways, open areas, or floors where a single wall unit does not always allow for balanced coverage of all zones. Once the network is properly adjusted, the client enjoys more natural comfort, with fewer marked differences between rooms.

A more discreet interior aesthetic

The Slim Duct often appeals to homeowners who place great importance on the appearance of their home. In a renovated living room, a master bedroom, or a neat open area, some clients prefer not to install a visible wall unit. The ducted system meets this need by hiding the indoor unit in a technical area.

Only the grilles remain visible. Well chosen and well positioned, they blend discreetly into the ceiling or wall. This discretion is one of the main reasons why many customers in Longueuil, Boucherville, Saint-Bruno-de-Montarville, Saint-Lambert, and the South Shore are interested in ducted solutions.

Savings that depend on installation quality

A system that is efficient on paper can lose part of its advantage if the installation is poorly executed. In a ducted network, air leaks, poor insulation, or overly restrictive ducts can reduce performance.

This is why AirGreen pays so much attention to invisible details:

• sealing of joints;
• protection of insulated ducts;
• respect for service clearances;
• airflow validation;
• choice between low and high static pressure;
• logical positioning of grilles;
• vibration prevention;
• preparation of access for maintenance.

These steps contribute to more stable operation, better durability, and more efficient energy use.

Subsidies: a verification to do according to the exact model

Some heat pump equipment may be eligible for subsidy programs, depending on their efficiency, indoor/outdoor combination, and current official lists. For GREE Ducted systems, eligibility must be confirmed according to the exact model installed, its capacity, and its certification.

At AirGreen, we help customers validate these elements before finalizing their choice. This verification is important because a product family can include several capacities, several series, and several different combinations. The potential amount and eligibility should never be assumed without validation.

For customers in Montreal, Laval, Longueuil, North Shore and South Shore, this step can influence the net cost of the project and facilitate comparison between several options.

Mistakes to avoid before installing a ducted system

A ducted project deserves serious planning. Here are the most common mistakes we see when analyzing existing or poorly designed projects.

Choosing a device without analyzing the ducts

BTU capacity is not enough. The network must be compatible with the device. A system with too low static pressure will not be able to properly supply the most distant grilles.

Over-compressing flexible ducts

A crushed or overly bent flexible duct can reduce flow. Even a properly sized unit can perform poorly if air is blocked by a poorly installed path.

Neglecting service access

A hidden unit must remain accessible. Filters, panels, drains, electrical connections, and refrigeration connections must be inspectable during an HVAC maintenance or service call.

Forgetting the importance of air return

The system must be able to return air as efficiently as it distributes it. Insufficient return can cause noise, reduce flow, and harm performance.

Confusing discreet installation with inaccessible installation

A ducted system must be discreet but never buried in a configuration impossible to maintain. This is an essential nuance in attic projects.
