A GREE ducted heat pump integrated into the structure for discreet comfort in Terrebonne
In Terrebonne, on the North Shore, our AirGreen team completed a specialized HVAC installation of a GREE ducted system, also called ducted conduit, Slim Duct, or ductable. This type of installation is for homeowners who want to enjoy efficient heating and cooling while keeping main rooms free of visible wall units. The project goal was clear: integrate the equipment into the house structure, prepare a well-thought-out air distribution, and offer uniform comfort without compromising interior aesthetics.
The construction photo shows a particularly interesting element: the GREE indoor unit installed in a wood-framed space, with the panel open and the fans visible. This view helps better understand how a ducted system works. Air is not simply blown by a wall head into a single room; it circulates through a concealed unit, then is directed to carefully positioned ducts and grilles. In a residence in Terrebonne, this approach is ideal when you want to supply multiple zones with a compact, clean, and well-integrated system.
Unlike a wall-mounted heat pump, the GREE All Match Slim Duct R32 system is designed to be installed in a ceiling, false ceiling, attic, mechanical space, or accessible technical area. Occupants mainly see the supply and return grilles, while the mechanics remain hidden. The result is more understated, more architectural, and often better suited for high-end renovations, extensions, and homes where every visual detail matters.
A project where the available space guided every decision
In this installation in Terrebonne, one of the main challenges was integration in a restricted space. The system had to be positioned between framing elements, with sufficient access for maintenance, connections, drainage, and ventilation. A ducted installation is never just about placing a unit in a box: it is necessary to plan how the air will enter, how it will exit, how the filter will be accessible, how the ducts will be connected, and how the system can be inspected in the future.
Our technicians therefore worked with particular attention to several points:
- aligning the GREE unit in the available space;
- protecting cables and connections;
- preparing the sealing around the opening;
- maintaining realistic service access;
- compatibility between the existing structure and the planned air distribution;
- the reduction of vibrations in a built-in installation.
These are the details that make the difference between a simply functional installation and a durable, quiet, and easy-to-maintain HVAC installation.
Why choose a ducted system rather than a wall unit?
Several clients from Montreal, Laval, Longueuil, the North Shore, and the South Shore contact us when they hesitate between a traditional wall-mounted heat pump and a GREE ducted solution. The choice depends on the building, budget, desired level of integration, and the number of rooms to serve.
The ducted system becomes particularly relevant when:
- the client wants to avoid visible wall units;
- several small rooms need to be supplied;
- the residence is under renovation or construction;
- a false ceiling, attic, or mechanical space is available;
- comfort must be diffuse and uniform;
- interior aesthetics are a priority;
- the owner wants a more discreet solution for bedrooms, offices, or living areas.
In this project in Terrebonne, the concealed installation precisely allowed combining performance and discretion. The GREE unit is integrated into the structure, while the duct network can be developed around the house's architecture.
The GREE ducted range: several capacities according to real needs
AirGreen offers several GREE ducted systems, including the GREE FM Ducted models in low or high static pressure, as well as the GREE All Match Slim Duct R32. Available capacities notably include 9,000 BTU, 12,000 BTU, 18,000 BTU, 21,000 BTU, 24,000 BTU, 30,000 BTU, and 36,000 BTU, depending on series and configurations.
For a residential installation like this, capacity should never be selected solely based on area. We consider several factors:
- the level of insulation;
- solar orientation;
- the ceiling height;
- the number of rooms served;
- the length and diameter of the ducts;
- pressure losses;
- the desired noise level;
- the heating needs during winter;
- the configuration of the outdoor unit.
An undersized system will run too long and may lack capacity during temperature extremes. An oversized system can create short cycles, poorer humidity control, and comfort variations. For a GREE Slim Duct, sizing must therefore combine load calculation and air distribution logic.
Low static pressure or high static pressure: a decision that changes everything
Static pressure is a central element in a ducted installation. It represents the unit's ability to circulate air through a duct network despite the resistances created by lengths, bends, transitions, grilles, and filters.
A low static pressure unit generally suits a shorter and simpler network. It can be ideal when the unit is close to the rooms to be served and the ducts are properly sized.
A high static pressure unit is more suitable when the network is more demanding, with multiple outlets, longer lengths, or passage constraints. It allows for a better design margin, provided the installation is carried out by a team that understands airflows well.
In Terrebonne, the technical space visible in the photo calls for serious consideration of air circulation. The turbines visible inside the GREE unit remind us that the equipment heavily depends on the quality of the surrounding network. A high-performance machine cannot deliver its full capacity if the ducts are too narrow, too long, poorly connected, or poorly insulated.
An AirGreen installation that focuses on access, airtightness, and air distribution
A significant part of the work in this type of project happens even before startup. The installation must be designed for today but also for the years to come. A ducted system installed behind a wall finish or in a ceiling must remain accessible for cleaning, inspection, and HVAC maintenance. This is especially true for filters, connections, the drainage pump if present, and service panels.
The importance of service access
In the photo, you can clearly see the open unit, with the fans and motor accessible. This accessibility is essential. A ducted system that is too enclosed can become costly to maintain because each intervention would then require removing finishing materials.
At AirGreen, we emphasize this aspect during installations in Terrebonne, Laval, Montreal, Longueuil, on the North Shore and the South Shore. A well-positioned access panel, sufficient clearance, and a logical component layout make maintenance easier and extend the equipment’s lifespan.
Sealing around the unit and ducts
Sealing is another critical point. In a ducted installation, every air leak represents a loss of performance. A leak can send conditioned air into an undesired space, reduce airflow in rooms, create noise, or increase energy consumption.
For this project, the transition areas between the GREE unit, the framing, the ducts, and the service openings had to be carefully prepared. Using appropriate materials, sealing tapes, mastics, and solid fasteners helps maintain stable air distribution. The goal is simple: the air must go exactly where it is intended.
Drainage: a discreet but essential detail
In cooling mode, a heat pump produces condensation. In a wall system, the drainage is often visible or easier to locate. In a ducted system, you need to be even more vigilant because the unit is often hidden.
Drainage must have an adequate slope or, if necessary, be assisted by a condensate pump. It must also be accessible for inspection. Neglecting this aspect of the installation can cause damage to the structure, ceilings, or interior finishes. That’s why our technicians carefully check the drain path, fittings, and exit points.
The advantages of R32 refrigerant in the All Match Slim Duct series
The GREE All Match Slim Duct R32 series is part of the new generation of HVAC solutions. The refrigerant R32 is increasingly used in modern equipment due to its energy performance and improved environmental profile compared to some older refrigerants. For the customer, this means current technology, better aligned with the requirements of new residential installations.
Some GREE models in this category can also offer performance suited to Quebec winters, with low-temperature heating capacities down to about -30 °C depending on the model. This feature is important on the North Shore, where periods of intense cold are not uncommon. During the final selection, we always validate the exact model, its performance data, compatibility with the outdoor unit, and potential eligibility for applicable aid programs.
Subsidies and eligibility: what to check
Customers considering a HVAC installation in Terrebonne often ask us about subsidies. Some GREE Energy Star equipment may be eligible for programs such as energy efficiency initiatives, depending on current criteria, indoor/outdoor combination, capacity, certification numbers, and requirements at the time of installation.
At AirGreen, we assist customers with this verification to avoid assumptions. A brand name alone is not enough to confirm eligibility. The complete system combination, official data, invoice, compliant installation, and required documents must be validated.
Mistakes to avoid with a GREE ducted system
An installation of ducted systems can offer excellent comfort, but it requires real expertise. The most common mistakes are often invisible at first, then become obvious after a few weeks of use.
Among the mistakes to avoid:
- installing the unit in a space that is too difficult to access;
- forgetting a service hatch;
- choosing a BTU capacity without serious calculation;
- undersize the ducts;
- neglect the air return;
- create too many bends in the network;
- use a low-pressure unit on an overly demanding network;
- poorly insulate ducts in an attic or unheated area;
- neglect drainage;
- install grilles in places that create discomfort.
In this project in Terrebonne, our approach was precisely to anticipate these challenges. The unit had to be well positioned, accessible, neatly connected, and compatible with coherent air distribution.
A solution suited for renovated homes in Terrebonne
Terrebonne has many residences where owners seek to improve comfort without adding visible units in every room. The Slim Duct GREE systems are particularly interesting in homes with finished basements, extensions, renovated floors, office spaces, master suites, or open living areas.
One of the great advantages of ducted systems is design flexibility. Multiple rooms can be served with discreet grilles, airflow can be adjusted according to needs, and a cleaner interior appearance can be maintained. For homeowners who want to invest in a durable, well-integrated, and comfortable system, this option deserves serious consideration.
AirGreen’s role as a GREE Elite dealer
AirGreen is a GREE Elite dealer, which allows us to offer specialized expertise on ducted systems, including low and high static pressure models as well as the All Match Slim Duct R32 series. This relationship with the brand gives us access to technical information, training, original parts, and support tailored to more complex installations.
For a client, this represents a concrete advantage. A ducted installation is not just an equipment sale. It is a design, coordination, mechanical, electrical, refrigeration, and ventilation project. Our team handles the entire process: estimation, model selection, planning, installation, commissioning, client explanations, and after-sales service.
The expected result: uniform comfort, discretion, and reliability
Once the installation is complete and the system is well balanced, the client enjoys more stable comfort in the served areas. The air is distributed through ducts, which helps avoid concentrating the airflow in a single room. The grilles can be strategically positioned to better cover living spaces.
The GREE ducted system is therefore a relevant solution for those who want a high-performance heat pump that is discreet. In Terrebonne, this type of installation meets the needs of homeowners who are renovating, modernizing, or preparing a home for long-term comfort.
AirGreen tips for properly planning a ducted installation
Before installing a Slim Duct system, we recommend planning the following points:
Have the mechanical space evaluated before choosing the model
Available height, width, depth, and service access directly influence the choice of the indoor unit.
Consider the ducts before finishing work
The best time to plan a ducted system is before closing walls and ceilings. This allows for a cleaner and less intrusive installation.
Do not underestimate the air return
Good airflow alone is not enough. The air return must be properly sized to avoid noise, restrictions, and comfort loss.
Request a detailed estimate
A serious offer must explain the machine, ducts, accessories, constraints, possible exclusions, and installation steps.
Plan maintenance from the start
The filter, access panels, and internal components must remain accessible. An invisible installation should never become inaccessible.
