A GREE ducted installation in Lorraine designed for invisible, stable, and lasting comfort
In Lorraine, houses often stand out for their refined architecture, well-designed living spaces, and high expectations for indoor comfort. In this context, installing a GREE All Match Slim Duct R32 ducted system is a particularly attractive solution for homeowners who want to enjoy a high-performance heat pump without multiplying visible wall units in the rooms.
At AirGreen, we recently completed a full HVAC installation of a GREE ducted system in a residence in Lorraine, with an approach focused on three specific goals: discreetly integrating the system, ensuring uniform air distribution in targeted areas, and optimizing energy efficiency while respecting the building’s technical constraints.
Unlike a standard wall installation, a Slim Duct or ducted system requires much more advanced planning. It’s not just about installing an indoor and an outdoor unit. You need to analyze the volumes to be treated, air circulation, available static pressure, duct routing, maintenance access, insulation, condensate drainage, and the location of the outdoor unit. Every detail matters because a well-designed ducted system becomes almost invisible in daily life, but its comfort is felt in every room.
In this installation in Lorraine, the GREE outdoor unit was carefully installed on a sturdy wall mount, directly on the exterior foundation, near a brick wall. This setup helped keep the equipment well off the ground, facilitated drainage, and protected the unit from snow, ice, or debris buildup. Wall-mounted supports are especially relevant in several residential areas of the North Shore, where outdoor layout, side clearances, and weather exposure must be considered from the start.
Why choose a ducted system rather than a traditional wall unit?
A GREE ducted system is aimed at clients looking for a more integrated solution than a wall air conditioner or a classic wall-mounted heat pump. The indoor unit is hidden in a technical space, ceiling, false ceiling, convertible attic, or service area, while the air is distributed through ducts to one or more rooms.
This approach offers several concrete advantages:
- A more discreet appearance, ideal for homes where interior aesthetics are important.
- Better air distribution in several adjacent zones.
- More consistent comfort, with fewer sudden temperature changes.
- A reduction in visual clutter in the rooms.
- A more natural integration in high-end renovation projects.
- A very relevant solution for bedrooms, corridors, home offices, or compartmentalized living areas.
In the case of this residence in Lorraine, the client wanted to improve comfort without changing the appearance of the main rooms. The GREE All Match Slim Duct R32 proved to be an excellent choice because it offers centralized comfort in certain areas while maintaining a compact and discreet installation.
A GREE solution adapted to residences in Lorraine and the North Shore
Lorraine, like several municipalities on the North Shore, features varied residential configurations: single-family homes with finished basements, extensions, finished ceilings, areas difficult to cool, bedrooms far from the central area, or spaces where installing a wall unit would be visually less desirable.
The GREE All Match Slim Duct R32 system is well suited to this type of need, especially thanks to its compact design and integration flexibility. The ducted GREE range available at AirGreen includes several capacities, notably 9,000 BTU, 12,000 BTU, 18,000 BTU, 24,000 BTU, 30,000 BTU, and 36,000 BTU, allowing the system to be adapted to the reality of each residence.
The right capacity choice is never made by chance. A unit that is too small risks running constantly without reaching the desired comfort. A unit that is too large can cause short cycles, poor dehumidification, temperature fluctuations, and premature wear. That is why our team conducts a comprehensive analysis before installation: area, solar orientation, insulation, number of occupants, ceiling height, room layout, window type, wind exposure, and actual heating and cooling needs.
The importance of static pressure in a ducted system
In a ducted installation, static pressure is one of the most important points. It determines the capacity of the indoor fan to push air through the ducts, bends, grilles, filters, and diffusers. An improperly sized duct network can reduce airflow, increase noise, create uncomfortable zones, or force the equipment to operate beyond its ideal conditions.
At AirGreen, we pay special attention to this point in every HVAC project involving a Slim Duct system. For this installation in Lorraine, our team evaluated the possible duct routes before confirming the solution. The goal was to limit pressure losses, maintain stable airflow, and allow reasonable access for future HVAC maintenance.
GREE ducted systems can be offered in low or high static pressure configurations depending on the models and project needs. A low static pressure version is often suitable for a short and simple network, while a high static pressure version becomes relevant when the duct network is more developed or when multiple air outlets need to be supplied with a well-balanced airflow.
A neat and durable outdoor installation
The outdoor unit visible in this installation demonstrates a clean and structured approach. The GREE condenser was mounted on wall supports installed securely, with attention to stability, alignment, and clearance around the unit. The refrigerant lines and wiring were routed neatly to the wall, with appropriate mechanical protection.
This type of finish is essential. A poorly planned outdoor installation can lead to several problems: vibrations, noise transmitted to the building, snow accumulation, difficulty accessing for service, premature wear of connections, or a neglected appearance. Our team always prioritizes an installation that remains clean, safe, and practical in the long term.
In this residence in Lorraine, the presence of the brick wall and foundation required precise mounting. The supports had to be positioned to ensure the stability of the unit while respecting the necessary clearances for the ventilation of the device. An outdoor heat pump must breathe properly. The fan must be able to expel air without obstruction, and the unit must remain accessible for maintenance, inspections, and any interventions.
The role of the R32 refrigerant in this GREE range
The GREE All Match Slim Duct R32 series uses the refrigerant R32, a technology increasingly present in modern HVAC equipment. R32 is valued for its energy efficiency and performance in next-generation systems. For homeowners, this translates into equipment designed to offer a good balance between performance, consumption, and comfort.
The installation of a system using R32 must be entrusted to qualified professionals. Work on refrigerant lines, fittings, leak tests, vacuuming, and commissioning requires precise technical expertise. At AirGreen, our refrigeration technicians follow the required procedures to ensure a reliable, clean installation that complies with applicable standards in Quebec.
It is also important to remember that a heat pump system should never be treated as a simple plug-and-play device. The quality of the installation directly influences performance, lifespan, noise level, energy efficiency, and customer satisfaction.
A structured AirGreen project, from design to commissioning
Needs analysis and selection of the right equipment
Before this installation in Lorraine, our team took the time to understand the client's expectations. The main need was clear: to improve indoor comfort while avoiding a solution that is too visible in the rooms. The client was looking for a clean, discreet, efficient, and durable installation.
We therefore directed the discussion towards a GREE ducted solution, capable of distributing air through ducts while keeping the indoor equipment out of sight. This approach is particularly appreciated by homeowners who want to preserve the interior design of their home, especially in renovated or well-furnished spaces.
The model selection was made based on the required capacity, duct configuration, available space for the indoor unit, heating and cooling needs, as well as the feasibility of the refrigerant line route to the outdoor unit. The capacities offered in the range allow adapting the solution to several scenarios, from a small bedroom area to a larger residential zone.
Duct network design: a step that makes all the difference
The comfort of a ducted system depends as much on the equipment as on the duct network. An excellent machine poorly connected to improperly sized ducts will give a disappointing result. Conversely, a properly designed system can offer a remarkable comfort experience.
For this installation, our team paid attention to several elements:
- Positioning the indoor unit to reduce duct length.
- Choosing air outlets for even distribution.
- The air return, essential for the proper functioning of the system.
- Reducing unnecessary bends to limit pressure losses.
- Acoustic control to avoid excessive air noise.
- Future access for filter cleaning and CVAC maintenance.
- Managing the condensation drain to prevent any risk of unwanted leakage.
A ductable system is not just a technical solution; it is an integration project. You have to consider the client’s comfort but also the house itself: structure, finish, access, aesthetics, after-sales service, and durability.
A clean installation in a finished residential environment
One common challenge in existing residences is carrying out the work without turning the house into a major construction site. In this installation in Lorraine, we planned the steps to limit unnecessary openings, protect surfaces, and keep a clean workspace.
CVAC work in a finished house requires a lot of discipline. Our teams must coordinate drilling, pipe routing, indoor unit installation, electrical connections, outdoor unit installation, and commissioning, all while respecting the premises. This attention to detail is often what distinguishes a proper installation from a truly professional one.
The client particularly appreciated the clarity of the explanations before the work. We took the time to explain how the system works, the location choices, the technical constraints, and the advantages of ducted systems compared to a wall unit. This transparency avoids unpleasant surprises and allows the client to understand exactly what will be installed.
Commissioning: the moment when the quality of the installation is confirmed
Once the equipment is installed, commissioning is an essential step. It confirms that the system is working correctly, that pressures and temperatures are consistent, that airflows are adequate, that the drain functions properly, and that the controls respond as expected.
For this GREE All Match Slim Duct R32 installation in Lorraine, our team checked the operation in cooling and heating according to the conditions available at the time of installation. The tests generally include:
- Refrigerant connections check.
- System vacuuming.
- Electrical connections check.
- Validation of the outdoor unit operation.
- Airflow check at outlets.
- Air return check.
- Condensate drain test.
- Explanation of controls to the client.
- Usage and maintenance advice.
This step is often underestimated, but it is fundamental. A thorough commissioning allows quickly spotting an anomaly, adjusting the settings, and ensuring the system delivers the expected comfort.
Thermal comfort: what the client notices from the first days
With a ducted heat pump, the comfort is different from that of a traditional wall unit. The air is generally distributed more gently, more evenly, without a direct jet too concentrated on one area. In a house in Lorraine, this feature becomes particularly interesting when several rooms need to be treated simultaneously.
The client benefits from a more stable temperature, better air circulation, and quiet operation. Since the indoor unit is hidden, the perceived noise in the rooms can also be reduced when the duct network is well designed and properly installed.
This type of solution is often chosen for bedrooms, master suites, offices, family areas, and spaces where acoustic comfort is important. In a teleworking or family living context, this discretion can make a real difference daily.
Subsidies and eligibility: a point to verify according to the exact model
Several high-efficiency GREE systems may be eligible for certain energy subsidies, depending on the exact model, capacity, certification, indoor-outdoor pairing, and the criteria in effect at the time of application. At AirGreen, we assist our clients in understanding the available programs, especially for installations in Montréal, Laval, Longueuil, on the North Shore and the South Shore.
In the case of a ducted system, it is important to verify eligibility based on exact model numbers. Two seemingly similar units can have different features depending on capacity, refrigerant, indoor-outdoor combination, or available certifications. That is why we always recommend confirming details before installation and keeping the required documents after the work.
At AirGreen, we provide the client with the necessary installation documents, including the invoice and useful information for subsidy applications when the installed model is eligible. This approach helps the owner submit their file more easily and reduces the risk of errors.
Mistakes to avoid with a ducted system
Installing a ducted system requires special expertise. Here are some common mistakes we see in the market and systematically avoid at AirGreen:
Choosing capacity based only on area
Area is a starting point, but it is not enough. Insulation, windows, orientation, ceilings, internal loads, and room layout strongly influence capacity choice.
Neglecting the air return
A ducted system must be able to return air efficiently. Poorly located or undersized air returns can create noise, reduce performance, and harm comfort.
Using ducts that are too long or too narrow
Undersized ducts increase pressure losses. The system can then become noisy, less efficient, or unable to deliver the required airflow.
Forgetting access for maintenance
A filter or indoor unit that is hard to access quickly becomes a problem. We always consider future service during design.
Installing the outdoor unit too close to an obstacle
The condenser must have enough space to exhaust air. Poor outdoor airflow can reduce performance, especially during high demand periods.
Underestimating drainage
Condensate management is essential. Poor drainage can cause interior damage, odors, or system shutdowns.

Expertise useful for complex projects
Ducted systems are often chosen when projects have greater constraints: limited ceiling height, restricted technical space, renovated homes, interior architecture to preserve, multiple rooms to treat, or a need for more discreet comfort. It is precisely in these situations that experience makes a difference.
We have completed similar installations in several areas, including Montreal, Laval, Longueuil, on the North Shore and the South Shore. Each project is different. In some cases, work must be done in an attic with limited access. In others, ducts must be integrated into a false ceiling. Sometimes, the challenge is outside: distance between units, condenser location, condominium restrictions, electrical access, or clearance management.
This range of experience allows us to anticipate problems before they become costly. For homeowners, this means a smoother, cleaner, and more reliable installation.
Practical advice for homeowners considering a Slim Duct system
If you are thinking of installing a GREE ducted heat pump in your home, here are some useful tips:
Plan the indoor space before choosing the model
The indoor unit of a ducted system must be installed in an accessible space. Before choosing a capacity, you must confirm that the location allows for proper installation, good air return, and access for maintenance.
Think about comfort room by room
A ducted system can serve multiple zones, but you need to consider the actual use of the rooms. A bedroom, an office, and a living room do not have the same needs or usage schedules.
Do not neglect acoustics
The choice of ducts, grilles, and air velocity influences the noise level. A well-designed installation should aim for thermal and acoustic comfort.
Check subsidies before starting work
Eligibility must be confirmed according to the specific models. It is best to verify the information before finalizing the equipment choice.
Choose an installer who understands ducted systems
Not all HVAC contractors have the same experience with ducted systems. This type of installation requires specific expertise in sizing, static pressure, and integration.
Final result: a discreet, efficient, and well-integrated system
At the end of this installation in Lorraine, the client obtained a GREE ducted solution that met their expectations: a discreet system, a neatly installed outdoor unit, air distribution designed for comfort, and an installation carried out with rigor.
The great advantage of the GREE All Match Slim Duct R32 is its ability to integrate into the home without imposing a significant visual presence. For homeowners who want to avoid visible wall units while enjoying modern comfort, this solution is a very relevant option.
At AirGreen, we believe that a good installation is not just about making equipment work. It must be designed for the years to come: maintenance, access, efficiency, noise, aesthetics, safety, and customer satisfaction. This project in Lorraine is an excellent example.
