A DoubleZone installation in Brossard designed for a building where every inch counted
In Brossard, AirGreen carried out a particularly precise HVAC installation: a GREE FREE MATCH R32 DoubleZone heat pump, configured to supply two indoor zones from a single outdoor unit. This project clearly illustrates a reality we often encounter on the South Shore: owners want to improve their comfort with a high-performance solution, but the available space to install the outdoor equipment is sometimes limited, irregular, or surrounded by architectural elements that must be respected.
In this installation, the outdoor unit was placed in a narrow space between two very different surfaces: a brick wall on one side and horizontal exterior siding on the other. Just above, a window imposed height, clearance, and aesthetic constraints. Below the unit, the presence of a basement window also required special attention to preserve access, safety, and the building’s overall appearance.
The result is a clean, compact, and functional installation, with a GREE outdoor unit securely mounted on metal wall brackets, well off the ground and positioned to optimize the machine’s operation. The refrigerant lines are protected by a white vertical conduit that discreetly blends with the existing siding, while the electrical connections are professionally organized.
This type of project requires rigorous execution. A DoubleZone heat pump is not simply a larger machine than a single-zone system. It involves more connections, more precise planning of the refrigerant line routing, careful clearance checks, and close coordination between the two indoor units and the outdoor unit.
Why a GREE FREE MATCH R32 DoubleZone was a suitable choice
The GREE FREE MATCH R32 model is an interesting multi-zone solution for homeowners who want to cool and heat two distinct spaces without installing two separate outdoor units. In a residential area like Brossard, where side yards can be narrow and the building's exterior appearance remains important, this setup offers a clear advantage.
With a single outdoor unit, it becomes possible to serve two rooms or two areas of the house while limiting clutter. Occupants can adjust temperatures independently according to the actual needs of each zone. For example, a living area may require more cooling in the afternoon, while a bedroom or office may need a different setting in the evening or overnight.
The inverter technology of this type of heat pump also allows for more stable modulation. Rather than operating only by frequent starts and stops, the system adjusts its power according to demand. This modulation contributes to more consistent comfort, a more stable noise level, and better energy consumption management.
The refrigerant R32, used in this generation of GREE systems, also fits into the evolution of modern HVAC equipment. It is increasingly present in new residential installations and allows manufacturers to offer efficient systems with a more current approach to air conditioning and heat pump heating.
An outdoor installation in a very limited space
The project photo clearly shows one of the main challenges: the outdoor unit had to be installed in a narrow area, framed by the brick facade, exterior siding, and building openings. In this context, positioning could not be improvised.
Our technicians had to consider several factors:
- the available height under the main window;
- the clearance needed in front of the unit's fan;
- the presence of a basement window;
- the wall's strength for the supports;
- the vertical passage of ducts;
- future access for HVAC maintenance;
- the visual integration into a visible residential space.
The unit was installed on sturdy wall mounts, which keeps it off the ground. This approach protects the equipment from snow buildup, splashes, debris, and frost-related stress at ground level. It also facilitates drainage and helps maintain better air circulation around the machine.
In an installation like this, the height must be well calculated. Too low, the unit could be affected by snow and obstacles. Too high, it could harm aesthetics, complicate connections, or reduce access to service panels. The right balance is found in the details, and this is precisely where AirGreen’s experience makes the difference.
The importance of wall supports in an installation in Brossard
Wall supports are not only used to hold the outdoor unit. They play an important role in stability, durability, and acoustic comfort. A heat pump that is poorly supported can transmit vibrations to the building, generate noise, or lose its level over time.
On this site, metal supports were installed to keep the unit stable and aligned. We always pay attention to the wall structure, anchor points, equipment weight, and the conditions the installation will face throughout the seasons.
In Brossard as elsewhere on the South Shore, freeze-thaw cycles, snow accumulation, and moisture can put an outdoor installation to the test. A solid attachment and good positioning reduce the risks of displacement, vibration, and premature wear.
A clean and discreet duct passage
A particularly successful aspect of this installation is the vertical passage of the ducts. The white conduit, installed along the exterior siding, protects the refrigerant lines, communication wiring, and related elements while giving the whole a much cleaner finish.
In a DoubleZone heat pump installation, the line routing requires more planning than a simple single-zone wall system. Two indoor units generally mean more connections, more coordination, and more precision in the routing. The lines must be protected against weather, UV rays, impacts, and unwanted movements.
A well-installed conduit offers several advantages:
- mechanical protection of the ducts;
- better exterior appearance;
- reduced risk of insulation damage;
- easier path to inspect;
- more professional finish on the facade;
- better integration with the building.
In this project, the light color of the conduit naturally blends with the siding, making the installation less visible. This kind of detail is important for homeowners, especially when the unit is located in a side yard or an area visible to passersby.
Electrical connections: safety and compliance above all
To the right of the outdoor unit, you can see the electrical box installed nearby. In a professional HVAC installation, the electrical part must be handled with as much care as the refrigerant connections. A GREE FREE MATCH R32 heat pump requires proper power supply, compliant protection, and a clean installation.
Our teams coordinate the necessary steps to ensure the connection is safe, accessible, and compliant with applicable requirements. The outdoor box must be placed conveniently for maintenance, without obstructing unit clearances or creating unnecessary tension on the cables.
A poorly planned electrical installation can cause operational problems, outages, overheating risks, or difficulties during future interventions. At AirGreen, we aim for a complete and durable installation, not just a quick startup.
A multizone solution suited for homes in Brossard, Montreal, Laval, Longueuil, the North Shore, and the South Shore
This installation in Brossard is a great example of the type of project we regularly carry out in Greater Montreal. Townhouses, duplexes, triplexes, condos, and properties with limited side space often require custom solutions. In these situations, a GREE FREE MATCH R32 DualZone heat pump can be an excellent choice when the building needs two comfort zones but the outdoor space does not allow for multiple units.
In Montreal, Laval, Longueuil, on the North Shore and the South Shore, we often see similar setups: brick walls, vinyl or aluminum siding, closely spaced windows, narrow access, nearby electrical panels, neighborhood constraints, and appearance rules. The role of an experienced HVAC contractor is to turn these constraints into a coherent, reliable, and clean installation.
The comfort achieved with two independent zones
A 2-head heat pump better meets the real needs of the occupants. In a house, not all rooms behave the same way. A sun-exposed room can become hot quickly, while a basement or shaded area can stay cooler. A single-zone system can sometimes create uneven comfort, especially when air must circulate through several closed or distant rooms.
With a DoubleZone system, each indoor head can be used according to occupancy and time of day. This flexibility not only improves comfort but also allows for smarter energy use. It is not always necessary to cool or heat the entire house with the same intensity.
For families, teleworkers, or owners who use rooms differently throughout the day, this zone autonomy becomes a very tangible advantage.
The specific challenges of a wall combining brick and siding
On this project, the facade combined two materials: brick and exterior siding. This type of configuration requires great precision during the planning of the route. Drilling, fixing, and routing ducts near different materials can create technical and aesthetic challenges.
Brick offers a solid surface, but it requires the right tools, the right anchors, and special attention to avoid cracks or unnecessary damage. The siding, on the other hand, demands a clean finish to prevent leaks, movement, or poorly sealed openings.
Our technicians therefore worked with a simple logic: respect the existing building while ensuring a durable installation. The vertical duct was positioned to minimize visual impact, the supports were fixed securely, and the unit was placed to maintain proper clearances.
Mistakes to avoid during a DoubleZone installation
Several owners compare the prices of wall-mounted heat pumps or wall air conditioners without always realizing that the quality of the installation influences the result as much as the choice of the machine. Here are the most common mistakes we help our clients avoid.
Installing the outdoor unit in a space that is too tight
An outdoor unit must exhaust and intake air properly. If it is placed too close to a wall, fence, staircase, or other obstacle, its performance can decrease. The compressor may work harder, and maintenance becomes more complicated.
Neglecting the appearance of ducts
Ducts visible on a facade can harm the building's appearance if they are misaligned or poorly protected. A clean, well-installed, and well-oriented duct provides a much more professional finish.
Forgetting snow and winter conditions
In Brossard and Greater Montreal, a heat pump must be installed with Quebec winters in mind. A unit placed too low or poorly cleared risks being affected by snow accumulation, ice, or ground splashes.
Poorly choosing the location of indoor units
A DoubleZone heat pump delivers good results only if the indoor units are well positioned. You need to consider air circulation, doors, corridors, windows, heat sources, and lifestyle habits.
Comparing price only
A lower price can hide shortcuts: less robust supports, poorly protected ducts, minimal finishing, incomplete commissioning, or lack of support. An HVAC installation must be evaluated as a complete system.
Commissioning: an essential step
Once the equipment is installed, commissioning is a decisive step. It allows verifying that the system works properly, that the connections are sealed, that the units respond well, that heating and cooling modes are operational, and that the customer understands the basic usage.
For a GREE FREE MATCH R32 DoubleZone, this step is particularly important because both zones must be tested individually. It is necessary to ensure that each indoor unit communicates correctly with the outdoor unit and that the system's behavior matches the demand.
At AirGreen, we place great importance on this phase. A well-done installation does not stop at the physical assembly of the machine. The system must be tested, explained, and left in a clean, safe, and ready-to-operate condition.
Subsidies and eligibility: carefully check the exact model
Several owners in Brossard, Montreal, Laval, Longueuil, on the North Shore and the South Shore also contact us to understand the subsidies available for their project. Financial aid programs, such as those related to efficient heat pumps, can vary depending on the exact model, installed configuration, current criteria, and provided documents.
For a multizone heat pump, it is important to verify precise information before purchase: brand, model, capacity, performance, eligibility, and required documents. AirGreen helps its clients gather the necessary information, including the invoice, installation details, and system references.
We always recommend confirming the eligibility of the exact model, as two machines that look similar can have different criteria depending on their configuration.
HVAC maintenance after installation
A careful installation must also be properly maintained. For a DoubleZone heat pump, maintenance includes the outdoor unit and the two indoor heads. Filters must be cleaned regularly, coils must stay clean, drains must be checked, and the outdoor unit must be cleared of leaves, snow, and debris.
In the case of this installation in Brossard, the outdoor unit is placed in an accessible location, which will facilitate future inspections. The space around the unit allows for work without having to unnecessarily dismantle parts or work in difficult conditions.
Good HVAC maintenance helps maintain energy efficiency, reduce noise, preserve air quality, and extend the system's lifespan. It is an essential part of long-term performance.
