A DoubleZone installation on brick in Fabreville: precision, solidity, and clean integration
In Fabreville, in the western sector of Laval, our AirGreen team completed the installation of a GREE FREE MATCH R32 DoubleZone heat pump, consisting of 2 zones and 2 wall-mounted heads, to provide targeted comfort in two distinct areas of the residence. The project stands out for an outdoor installation on a brick wall, with the unit fixed on wall mounts, ducts grouped in a vertical duct matching the facade color, and an integration designed to remain clean, accessible, and durable.
The construction photo clearly shows the GREE outdoor unit installed under a window, securely anchored on a foundation and a brick wall. To the right of the unit, a vertical reddish-brown metal duct protects and conceals the refrigerant lines and wiring. This finish is especially important on brick buildings, where a poorly planned installation can quickly become too visible or harm the appearance of the backyard. Here, the goal was to combine performance, safety, accessibility, and discretion.
This type of project requires excellent mastery of residential HVAC installation. A DoubleZone heat pump is not just an outdoor unit with two indoor heads: it is a complete system that must be sized, connected, protected, and commissioned according to precise criteria. In Fabreville, our team had to consider the facade configuration, available height, the window above the unit, duct routing, electrical protection, and future access for HVAC maintenance.
Why a GREE FREE MATCH R32 DoubleZone was suitable for this residence
The GREE FREE MATCH R32 model is an interesting multi-zone solution for homeowners who want to heat and cool two areas without multiplying outdoor units. In this installation in Fabreville, the goal was clear: to offer independent comfort in two zones of the house while maintaining a compact and well-organized outdoor setup.
A DoubleZone heat pump allows two wall units to be connected to a single outdoor unit. Each indoor unit can meet the specific needs of its zone, which is especially practical in homes where some rooms are harder to heat or cool than others. An open area, an upstairs bedroom, a home office, a finished basement, or an extension can have very different needs depending on orientation, insulation, sunlight, and daily use.
The FREE MATCH R32 platform from GREE is designed for this type of application. It allows flexible management of multiple zones, with a modulating capacity that adapts to actual demand. Rather than operating abruptly, the system adjusts its output according to the needs of the indoor units, which helps maintain a more stable temperature and better comfort.
For homeowners in Montreal, Laval, Longueuil, the North Shore, and the South Shore, this type of system often represents a very balanced solution: a single outdoor unit, two comfort zones, good energy efficiency, and a more discreet installation than multiple devices.
An outdoor installation on wall mounts: a practical choice for the Quebec climate
In this installation, the outdoor GREE unit was installed on sturdy wall mounts. This choice is important, especially in a climate like Laval’s, where snow, ice, dead leaves, and temperature variations can affect outdoor equipment.
Wall mounting keeps the unit above the ground, which reduces the risk of obstruction by snow and makes clearing around the device easier. It also helps limit vibrations transmitted to the ground and keeps the outdoor space more open. In this project, the unit is positioned at a practical height, with sufficient access for maintenance, cleaning, and future inspections.
The location under the window also required careful planning. An outdoor unit must have enough space to discharge air without obstruction. It must not be installed too close to an obstacle, a side wall, or an enclosed space that would limit its ventilation. In this case, our team positioned the unit to preserve good air circulation in front of and around the unit.
A successful outdoor installation relies on several elements:
- wall mounts securely anchored;
- positioning respecting the required clearances;
- sufficient height to limit snow accumulation;
- adequate accessibility for maintenance;
- mechanical protection of the lines;
- an exterior finish consistent with the building.
These elements may seem technical, but they directly influence the durability and performance of the system. A well-installed heat pump operates under better conditions and requires fewer corrective interventions over the years.
The vertical conduit: an essential finish on a brick facade
One of the most visible details in this installation is the vertical conduit installed to the right of the outdoor unit. Its reddish-brown color matches very well with the brick and the architectural elements already present on the facade. This finishing choice results in a cleaner look than a set of exposed lines.
In an HVAC installation, refrigerant lines, communication wiring, and sometimes drainage must be routed between the outdoor unit and the indoor heads. Without protection, these elements can be vulnerable to weather, impacts, UV rays, and movements caused by freeze-thaw cycles. A well-installed conduit protects the components and improves the overall appearance of the project.
On a brick house, drilling and fastening require special attention. Unnecessary holes must be avoided, the right anchors used, the wall structure respected, and the lines ensured to follow a logical path. In this project in Fabreville, the vertical passage allows the ducts to be grouped and results in an orderly installation.
This approach is particularly appreciated by homeowners who want a high-performance heat pump without compromising the aesthetics of their home. A clean installation is not limited to the interior: the exterior must also be neat, especially when the unit is visible in a yard, alley, side passage, or rear facade.
Challenges encountered on this site in Fabreville
Each installation has its constraints. In Fabreville, the building presented several elements to consider: brick facade, window above the unit, nearby side wall, limited space, vertical duct passage, and the need to maintain a neat finish.
Our technicians had to plan the line routes to serve the two indoor units while reducing the visual impact outside. In a 2 zones – 2 heads system, the duct path can be more complex than with a single-zone heat pump. Maximum accepted lengths, height differences, drainage slopes, access to connections, and line protection must be considered.
The main challenges of this project were as follows:
- install the outdoor unit at a practical and safe height;
- securely anchor the supports in a suitable facade;
- maintain good ventilation around the unit;
- group ducts in a clean vertical shaft;
- limit visible penetrations;
- respect the aesthetics of the brick wall;
- ensure sufficient accessibility for HVAC maintenance;
- coordinate electrical and refrigeration connections.
It is precisely these details that make the difference between a simply functional installation and a professional installation. At AirGreen, we place great importance on this step because it influences the customer experience long after the initial startup.
Two comfort zones with a single outdoor unit
The main value of a DoubleZone heat pump is its ability to create two independent comfort zones. In a residence, needs are not always uniform. A sun-exposed room can become too hot in summer, while another remains cooler. A bedroom may require a different setting than a living room. A home office may be used all day, while another area is only used in the evening.
With two wall units, the customer can better manage their comfort daily. Each zone can be adjusted according to the actual use of the space. This flexibility is especially useful in homes in Laval, where extensions, renovations, finished basements, and interior divisions sometimes create significant temperature differences.
A single outdoor unit also helps preserve outdoor space. Rather than installing two independent devices, the GREE FREE MATCH R32 system centralizes heating and cooling production outside, then distributes comfort to two heads. It is a compact solution well suited to urban yards, narrow side passages, and buildings where available space is limited.
The role of R32 in new heat pump installations
The GREE FREE MATCH R32 model uses the refrigerant R32, a fluid increasingly present in new generations of heat pumps and wall air conditioners. R32 is known for its good thermodynamic properties and reduced environmental impact compared to many older refrigerants.
For homeowners, choosing an R32 system means investing in newer technology that meets current market standards. This evolution is important in the HVAC sector, where devices are becoming more efficient, more compact, and better suited to modern residential needs.
In a region like Laval, where heating and cooling systems must operate under varied conditions, it is important to choose a well-designed device and to entrust installation to a team that understands the product's requirements. The refrigerant, fittings, line length, condensate drainage, and commissioning must be handled rigorously.
Performance, efficiency, and seasonal comfort
A well-chosen heat pump can improve comfort all year round. In summer, it allows targeted cooling and better humidity control. In autumn and spring, it can provide efficient heating without unnecessarily straining the home's main system. In winter, depending on conditions, it can contribute to heating and improve comfort in the served rooms.
The GREE FREE MATCH R32 system is designed to modulate its capacity according to demand. This modulation helps avoid sudden temperature changes and improves perceived comfort. It also contributes to more rational energy use, since the system does not always need to operate at full capacity.
For an owner comparing several options in Montréal, Laval, Longueuil, on the North Shore or on the South Shore, the question is not limited to the price of the machine. The house configuration, number of zones, installation quality, noise level, possible subsidies, parts availability, and after-sales service must be evaluated. It is in this comprehensive analysis that a well-designed project takes its full value.
Subsidies and eligibility: an aspect to check before choosing
Subsidy programs, notably LogisVert from Hydro-Québec, can represent a significant financial advantage for owners who install an eligible heat pump. However, the criteria depend on the exact model, certification, performance, capacity, and the rules applicable at the time of the application.
At AirGreen, we help customers better understand the information needed for their subsidy application. After installation, documents such as the invoice, model numbers, and technical details must be kept to facilitate the process. The customer usually submits their application according to the program requirements, and the amounts may vary.
It is important to remember that a subsidy should not be the only selection criterion. An eligible device must also meet the actual needs of the building. An oversized or poorly placed machine can harm comfort. An undersized machine may not meet expectations. A professional evaluation helps avoid these mistakes.
The importance of HVAC maintenance after installation
Once the system is installed, HVAC maintenance becomes essential to preserve the machine's performance and lifespan. Wall heads must be cleaned regularly, especially the filters, to maintain good air circulation. The outdoor unit must be kept clear of leaves, snow, dust, and debris.
In this installation in Fabreville, wall mounting facilitates access to the outdoor unit. This makes it easier to clear the device and check its visual condition throughout the seasons. The vertical duct also protects the lines, which helps reduce the risk of premature wear.
Regular maintenance allows you to:
- maintain better energy efficiency;
- reduce noise or vibration risks;
- preserve indoor air quality;
- avoid performance losses;
- extend the equipment's lifespan;
- detect anomalies earlier.
For owners, it is a simple but important action. A well-maintained heat pump retains its performance better and offers more stable comfort.
Mistakes to avoid during a DoubleZone installation
A multi-zone installation must be carefully planned. Some mistakes often recur when the project is done too quickly or without a complete analysis.
The first mistake is choosing the head locations based only on appearance. Positioning must first consider air diffusion, room use, available height, and duct routing.
The second mistake is neglecting the outdoor routing of the lines. On a brick facade like this project, ducts must be protected and organized. A well-chosen duct can completely transform the final appearance.
The third mistake is placing the outdoor unit too low. In the Quebec climate, snow and ice can affect operation. Mounting on wall brackets is often an effective solution when the structure allows it.
The fourth mistake is not thinking about future maintenance. A unit that is hard to access or poorly positioned indoor heads complicate cleaning and inspections.
The fifth mistake is choosing a machine without considering the actual building. An HVAC installation must be adapted to the area, insulation, windows, orientation, and occupants' habits.
