A discreet ducted system designed for a Rosemère house where comfort had to remain invisible
In Rosemère, we recently completed an HVAC installation that perfectly illustrates why ducted systems, also called ducted conduits, Slim Duct or ductable, are becoming an increasingly sought-after solution by homeowners who want to heat and cool efficiently without installing visible wall units in living spaces.
In this residence on the North Shore, the client wanted to achieve uniform comfort in several zones of the house while maintaining a clean and discreet interior finish. The goal was not just to add a high-performance heat pump: it was necessary to integrate a complete system into the existing architecture, with well-thought-out air distribution, low noise levels, and future access for HVAC maintenance.
The choice fell on a GREE ducted solution, more precisely in the GREE All Match Slim Duct R32 family, a range offered by AirGreen for residential and multi-zone projects in Montreal, Laval, Longueuil, on the North Shore and the South Shore. This series combines comfort, discretion, and installation flexibility, especially when available space in ceilings, false ceilings, attics, or technical areas is limited.
Why a GREE ducted system was the right choice for this house
Unlike a wall-mounted air conditioner or a classic wall-mounted heat pump, a ducted system allows the indoor unit to be hidden in a technical space, then distributes air through ducts to different rooms. For this project in Rosemère, this approach met three important priorities:
- preserve the interior aesthetics of the house;
- get a more stable temperature between rooms;
- reduce the presence of visible equipment in living areas.
The client wanted an efficient solution, but without the system becoming a dominant element in the decor. In this type of project, the most important work often takes place even before installing the machine: volume analysis, duct routing, grille placement, service access, air return management, and validation of structural constraints.
An installation where air distribution made all the difference
The project photo shows a central element of this type of installation: a metal distribution piece with several circular openings designed to receive flexible or rigid ducts depending on the chosen configuration. This type of component requires great precision, as each outlet must be positioned to respect the airflow planned for the served area.
In a ducted installation, performance does not depend solely on the brand of the machine. It also depends on the quality of the air network. An excellent device poorly connected can become noisy, inefficient, or uncomfortable. That is why our team paid special attention to several technical elements:
- the limitation of pressure losses;
- the quality of the metal fittings;
- the sturdiness of the assembly;
- the tightness of the connections;
- the orientation of the air outlets;
- the ability to access the system for inspection and service.
Every detail influences the final comfort. A bend that is too tight, a duct that is too long, an improperly sized air return, or a poor metal transition can reduce actual airflow, create whistling, or unnecessarily strain the system.
A GREE All Match Slim Duct R32 solution suited for demanding residential projects
The GREE All Match Slim Duct R32 range is designed for installations where a discreet, efficient, and adaptable system is sought. At AirGreen, we offer different capacities according to the building's needs, including units of 9,000 BTU, 12,000 BTU, 18,000 BTU, 24,000 BTU, 30,000 BTU, and 36,000 BTU, depending on the configuration and load calculations.
For this installation in Rosemère, the capacity selection was not made randomly. We evaluated the served area, insulation, sunlight exposure, room layout, ceiling heights, heating and cooling needs, as well as duct routing constraints. A ducted system requires a more rigorous approach than a simple wall-mounted installation because every decision affects multiple comfort zones at once.
R32, efficiency and modern design
The GREE All Match Slim Duct R32 series uses the refrigerant R32, known for its energy efficiency and reduced environmental impact compared to some older refrigerants. For homeowners in Rosemère, Laval, Montreal, or Longueuil who want to invest in a sustainable solution, this feature has become an important criterion.
Depending on the models and configurations, GREE ducted systems can offer reliable heating performance even during harsh Quebec winters, with some ranges designed to operate down to -30 °C. This cold weather heating capability is essential on the North Shore, where temperature variations can be significant between autumn, winter, and spring.
Low static pressure or high static pressure: an important technical choice
In the GREE range offered by AirGreen, we find both low static pressure and high static pressure systems. This distinction is essential for ducted projects.
A low static pressure unit is generally suitable for shorter networks, with few ducts and simple distribution. It is often chosen when the indoor unit is close to the supply vents and pressure losses are limited.
A high static pressure unit becomes more relevant when the network is more complex, when the ducts are longer, or when several rooms need to be served with a more elaborate distribution. In a house like the one in Rosemère, this analysis helps avoid two common mistakes: underestimating the network resistance or installing a unit that is too powerful to compensate for poor design.
The invisible work behind a clean installation
In this project, one of the challenges was to integrate the system without compromising the house's appearance. A Slim Duct system must remain discreet, but that does not mean the installation is simple. On the contrary, this type of project often requires more planning than a traditional wall installation.
Our technicians coordinated the location of the indoor unit, the routing of ducts, refrigerant connections, condensation drainage, and the location of the outdoor unit. The goal was to create a durable, quiet, and easy-to-maintain installation while minimizing visual impact.
We also paid special attention to drainage. In a ducted system, a poor slope or poor access to the drain can cause moisture, flow, or maintenance problems. That is why each drainage is carefully checked before closing the technical spaces.
A finish suited to high-end homes on the North Shore
In Rosemère, many homes feature refined interior finishes, detailed ceilings, open areas, and sometimes already completed renovations. In this context, the installation of an HVAC system must respect the existing environment.
The GREE ducted system limits the presence of visible equipment. Instead of having a wall unit in each room, air is distributed through more discreet grilles, chosen according to the project's aesthetics. This result is especially appreciated in living rooms, master bedrooms, home offices, and renovated spaces where owners want to avoid visual compromises.
Mistakes to avoid with a ducted system
A ducted heat pump can offer excellent comfort, but only if it is designed and installed correctly. In our projects in Rosemère, Montreal, Laval, Longueuil, on the North Shore and the South Shore, we often see the same mistakes when systems have been poorly planned.
The first mistake is to choose the capacity based solely on the area. Two houses of the same size can have very different needs depending on insulation, orientation, window placement, and room layout.
The second mistake is neglecting static pressure. An overly restrictive duct network can reduce airflow, increase noise, and harm efficiency.
The third mistake is forgetting service access. A hidden unit must remain accessible. At AirGreen, we always plan the installation with future maintenance, cleaning, inspections, and possible repairs in mind.
The fourth mistake is underestimating the importance of air return. Without a properly sized air return, even the best system can operate unstably.
An AirGreen expertise based on design, not just installation
Our work is not limited to installing a machine. For a gainable GREE project, we act as designers, installers, and technical advisors. This means we must understand the building, anticipate constraints, and propose a truly suitable solution.
As a GREE Élite dealer, AirGreen has specialized expertise in ducted systems, including duct network design, static load calculations, diagnostic procedures, and access to original parts. This expertise is particularly important for integrated systems, as a design error can be more difficult to correct after the work.
Our professional refrigeration teams work with a structured approach: on-site validation, clear proposal, scheduling of visits, careful installation, commissioning, flow rate checks, and explanations to the client.
The comfort achieved after installation
Once the system was running, the client immediately noticed a difference in temperature stability. The air was better distributed, without unpleasant direct drafts in the living areas. The ducted system allows for a gentler diffusion than a wall unit placed in a single room, which helps reduce temperature differences between zones.
The noise level was also an important point. Thanks to the design of the network, the positioning of the unit, and the choice of a Slim Duct solution, the operation remained discreet. For an owner who works from home or uses living spaces for long periods, this aspect is often as important as energy performance.
Subsidies and eligibility: a point to check depending on the model
Many clients ask us if GREE ducted systems qualify for subsidies, especially under programs like Hydro-Québec’s LogisVert. Eligibility depends on the exact model, configuration, performance data, installation compliance, and the criteria in effect at the time of the project.
At AirGreen, we support our clients in selecting relevant equipment and understanding the necessary documents. For homeowners in Rosemère, Laval, Montréal, Longueuil, the North Shore, and the South Shore, this assistance can make a significant difference when comparing options.
Why Rosemère is well suited for ducted systems
Rosemère includes many homes where owners seek comfort, quiet, and aesthetic integration. In this type of property, a ducted system can be an excellent solution, especially when wall units do not suit the interior layout.
Homes with accessible attics, technical basements, false ceilings, or storage areas above rooms can often accommodate a ducted unit with good efficiency. However, the project must be seriously analyzed before any decision. At AirGreen, we do not offer a ducted system simply because it is discreet; we recommend it when the building’s configuration allows for a reliable, efficient, and durable installation.
An installation designed to last
The durability of an HVAC system depends on three factors: equipment choice, installation quality, and ease of maintenance. In this project in Rosemère, these three elements were addressed together.
The choice of a GREE All Match Slim Duct R32 system met the expectations for comfort and discretion. The duct network design ensured effective air distribution. The installation was carried out with sturdy fittings, clean passages, and logical access for future service.
This approach reduces the risks of long-term problems: excessive noise, poor airflow, condensation, maintenance difficulties, or premature wear.
What homeowners should remember before choosing a ducted system
A ducted system is an excellent option when you want to combine centralized comfort and discretion, but it must be planned precisely. Before choosing a brand or capacity, you need to ask the right questions:
- which rooms need to be served;
- where the indoor unit can be installed;
- what type of ducts can be used;
- what static pressure will be required;
- how the air return will be designed;
- where the condensation water will be drained;
- what access will be available for maintenance;
- what actual capacity suits the building.
At AirGreen, we help clients answer these questions before presenting a final offer. This method avoids surprises and allows us to propose a solution consistent with the building's real needs.
AirGreen: a transparent approach for complex HVAC installations
For this installation in Rosemère, our team applied the same principles as in our projects in Montreal, Laval, Longueuil, on the North Shore and the South Shore: transparency, technical rigor, and respect for the client's home.
We always send a clear quote before starting work. Our technicians are trained to work in sometimes complex conditions, with special attention to cleanliness, safety, and quality of finishes. Our $5M liability insurance also allows homeowners, condominium associations, and property managers to work with us with full confidence.
A project that shows the potential of GREE ducted conduits
This project in Rosemère demonstrates that a well-designed HVAC installation can transform the comfort of a home without changing its interior appearance. Thanks to the GREE ducted range, careful air network design, and AirGreen's expertise, the client now enjoys better-distributed heating and cooling that is more discreet and better suited to their lifestyle.
For homeowners who are undecided between a wall-mounted heat pump, a central system, or a ducted system, this project highlights the importance of a professional assessment. The right choice is not always the most visible or the simplest at first glance. It is often the one that respects the building, the client's needs, and the technical requirements of the installation.
