Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
A Custom HVAC Installation in Baie-D’Urfé: Balancing Architectural Constraints and Seasonal Performance
In Baie-D’Urfé, wall-mounted heat pump projects often require special attention to the outdoor environment. Residences there feature varied configurations: brick walls, horizontal siding, narrow side access, shared backyards, elevated balconies, fences, trellises, exterior staircases, and areas prone to snow accumulation. For this installation, our AirGreen team installed a GREE CROSSOVER R32 wall-mounted heat pump, used as a wall-mounted air conditioner, supplementary heating system, and compact mini-split for efficient year-round comfort.
The project photo illustrates a particularly interesting installation: the GREE outdoor unit is fixed on a metal wall bracket, installed at a strategic height, between a brick wall and exterior siding. We also note the presence of snow on the ground, a green trellis, a fence, a confined side space, and a technical passage protected by conduit covers. This is not a "simple" installation in the ordinary sense of the term. Rather, it's a concrete example of an HVAC installation where every detail matters: stability, clearance, accessibility, weather protection, aesthetics, and durability.
At AirGreen, we know that a good system only performs at its best when installed methodically. The GREE CROSSOVER R32 offers an excellent combination of comfort, efficiency, and compactness, but its real performance largely depends on the quality of the installation. In a residential area like Baie-D’Urfé, where homeowners seek clean, discreet, and reliable installations, our approach is to integrate the equipment into the building without compromising appearance or performance.
An Outdoor Unit Mounted on the Wall: Why This Choice Was Essential
In this project, the outdoor unit was not placed on the ground. It was installed on a robust wall bracket, fixed to the brick wall. This choice addressed several technical objectives.
Firstly, the elevated installation limits the risks associated with snow accumulation. In Baie-D’Urfé, as elsewhere in Greater Montreal, winters can lead to significant ground accumulation, especially near walls, fences, or side passages. An outdoor unit placed too low can become partially blocked, which hinders airflow and can affect the functioning of the heat pump.
Secondly, the wall bracket frees up ground space. In the photo, the environment is already occupied by a trellis, a fence, and a narrow passageway. A ground base would have complicated maintenance, increased obstruction risks, and made the overall appearance less tidy. The wall bracket ensures a more open, stable installation better suited to the available space.
Finally, this type of support facilitates drainage and maintenance. The unit is accessible, visible, and protected from ground debris. For a homeowner, this means fewer complications when checking the appliance's condition or calling a team for HVAC maintenance.
An Installation Between Brick and Siding: Precision is Mandatory
One of the most important elements of this installation in Baie-D’Urfé was the coordination between two different exterior surfaces: a red brick wall and horizontal siding. Installing a GREE CROSSOVER R32 wall-mounted heat pump in this type of environment requires a precise understanding of the building.
The brick wall offers a solid surface for anchoring the bracket, but the correct fastening methods must be used to ensure the unit's stability. Poor fastening can lead to vibrations, unwanted noise, or long-term weakening of the support. Our technicians therefore took care to choose an appropriate structural area and securely fasten the bracket.
On the siding side, the refrigerant lines, wiring, and drain needed to be routed cleanly. The photo shows a brown-grey metal exterior casing that protects the passage of the conduits. This finish plays an important role: it protects the components from bad weather, UV rays, accidental impacts, and seasonal building movements.
This attention to detail in finishing is one of the characteristics that distinguishes a professional HVAC installation. A well-protected refrigerant line extends the system's lifespan and results in a much neater visual appearance.
The GREE CROSSOVER R32: A Relevant Choice for Residential Comfort
The GREE CROSSOVER R32 is a wall-mounted heat pump designed to offer a good balance of efficiency, reliability, and accessibility. It is particularly well-suited for homeowners who wish to improve their comfort without undertaking major renovations.
This model can serve as an efficient wall-mounted air conditioner during the summer and a supplementary heating source during cooler periods. Thanks to inverter technology, the system modulates its operation according to actual demand, which helps maintain a more stable temperature and avoid abrupt on-off cycles.
The R32 refrigerant also represents a significant advantage. Compared to several older refrigerants, it is known for its efficiency and reduced environmental impact. For homeowners in Montreal, Laval, Longueuil, the North Shore, and the South Shore, this type of technology represents a modern solution, aligned with growing expectations for energy performance and environmental responsibility.
Depending on the chosen capacity, exact features may vary, including BTUs, efficiency ratings, and eligibility for certain programs. In the context of a residential project, we always validate the building's actual needs before recommending a specific size. The goal is never to install the largest possible unit, but rather the system best suited to the space, insulation, solar exposure, and usage habits.
Challenges Visible in the Photo: Confined Space, Snow, and Technical Access
This installation in Baie-D’Urfé clearly demonstrates several typical constraints we encounter in the field.
Snow on the ground
The presence of snow highlights the importance of thoughtful positioning. An outdoor unit installed too low could be affected by accumulations, particularly during storms or after snow removal. The wall bracket limits this risk while allowing good airflow around the unit.
The trellis and the fence
The green trellis and the fence near the unit create a tighter environment. In this type of situation, it is necessary to avoid blocking the fan's air exhaust. A mini-split heat pump must breathe properly to function efficiently. Our technicians therefore ensure that the unit has the necessary clearances despite the existing configuration.
The brick wall
Brick offers good solidity, but it requires suitable anchors. A careless installation can generate vibrations or weaken the fastenings. Here, the wall bracket was installed stably to support the weight of the outdoor unit under real winter conditions.
Conduit routing
The exterior cover installed on the siding protects the conduits while providing a clean finish. This protection is essential in a climate like Quebec's, where temperature variations, ice, rain, sun, and wind can prematurely wear down exposed materials.
Why Wall-Mounted Installation is Often Preferable in West Island Residential Areas
In Baie-D’Urfé and several areas of the West Island of Montreal, houses often have well-landscaped yards, narrow side passages, and outdoor areas where aesthetics are very important. Homeowners want the benefits of an efficient wall-mounted air conditioner, but they don't necessarily want an outdoor unit to occupy a passageway or detract from the landscaping.
Wall-mounted installation addresses this reality well. It allows:
- to free up ground space;
- to reduce the risk of obstruction by snow;
- to facilitate cleaning around the unit;
- to better integrate the equipment into the building;
- to protect the appliance against certain impacts;
- to improve access for maintenance;
- to maintain a tidier appearance.
This type of installation must, however, be carried out by an experienced team. The choice of wall, height, anchors, level, clearances, and unit orientation must be carefully analyzed. At AirGreen, we regularly carry out this type of project in complex residential environments, as much in Montreal as in Laval, Longueuil, on the North Shore, and on the South Shore.
A Solution Adapted for Homeowners Who Want Air Conditioning Without Major Renovation Work
The GREE CROSSOVER R32 wall-mounted heat pump effectively meets the needs of homeowners who wish to improve their comfort quickly. Unlike a central system, a wall-mounted mini-split does not require a duct network throughout the house. It can be installed in a targeted manner to treat a main area: living room, open concept area, floor, office, bedroom, or apartment.
In this project in Baie-D’Urfé, the client wanted an efficient solution, but also an outdoor installation that would not hinder the use of the space. The wall bracket, the protected conduit passage, and the unit's positioning allowed this request to be met.
This is an important point for readers comparing different heat pump options. The choice of model is important, but adapting it to the building's reality is equally so. Two installations of the same appliance can yield very different results depending on the quality of installation, positioning, and commissioning.
Key Steps Performed by Our Team
An installation like this involves several steps, each having a direct impact on the system's performance and durability.
Location Assessment
Before installation, we analyze the indoor and outdoor space. It is essential to choose a location that allows for good air distribution indoors and a logical connection to the outside.
Wall Bracket Preparation
The bracket must be perfectly level, securely fastened, and suitable for the unit's weight. In this case, fixing to brick required special attention.
Outdoor Unit Installation
The GREE unit is then installed on the wall bracket, with the necessary clearances for ventilation and maintenance.
Conduit Passage
Refrigerant lines, wiring, and the drain are routed neatly, then protected by an exterior cover. This step is essential for durability and final appearance.
Connection and Vacuuming
Our technicians perform the refrigeration connection, leak test, and vacuuming. These steps should never be neglected, as they directly influence the system's reliability.
Commissioning and Verification
The system is tested in operation to confirm proper communication between the units, the appliance's response, and drainage. The client also receives the necessary explanations for correctly using their wall-mounted heat pump.
Errors to Avoid During a Mini-Split Installation in Baie-D’Urfé
Homeowners shopping for an HVAC installation should pay attention to several common errors.
Installing the unit too close to the ground
In a Quebec climate, snow accumulation can interfere with operation. An installation that is too low is rarely ideal in exposed areas.
Neglecting the solidity of the support
A poorly supported outdoor unit can vibrate, move over time, or generate unpleasant noises. The support must be adapted to the building.
Leaving conduits exposed
Unprotected conduits can be damaged more quickly. A well-installed cover improves durability and aesthetics.
Choosing an appliance without assessing real needs
An appliance that is too small may work constantly. An appliance that is too large may offer less stable comfort. Sizing must be done according to the building's configuration.
Entrusting the work to an unqualified team
Wall-mounted heat pump systems require specific skills. Refrigerant handling, connections, and commissioning must be carried out by qualified professionals.

At AirGreen, we install wall-mounted heat pumps, wall-mounted air conditioners, and mini-split systems in a wide variety of environments. This experience allows us to anticipate problems before they arise: insufficient clearance, incorrect support choice, overly exposed conduits, poorly directed drainage, difficult access, or noisy positioning.
This GREE CROSSOVER R32 installation in Baie-D’Urfé perfectly illustrates our working method. We adapted the installation to a restricted outdoor space, protected the conduits, used an appropriate wall bracket, and took winter conditions into account. The result is a clean, stable, and functional installation, designed to offer lasting comfort.
An Approach Focused on the Building, Not Just the Equipment
A good HVAC contractor doesn't just sell a machine. They must understand the building, the client's lifestyle, and the physical constraints of the location. That's why we take the time to evaluate each project before recommending a model.
For an installation like this, several elements must be validated:
- the location of the indoor unit;
- the distance between units;
- the structure of the exterior wall;
- exposure to snow and wind;
- access for maintenance;
- desired sound level;
- electrical availability;
- the cleanest path for the conduits;
- the exterior finish desired by the client.
This analysis allows for a more reliable and better integrated heat pump installation.
A result that combines comfort, discretion, and durability
The final result of this project is a GREE CROSSOVER R32 wall-mounted heat pump installed compactly, well-supported, and protected. The outdoor unit is placed at a height that limits risks associated with snow, the conduits are neatly framed, and the overall setup respects the visual constraints of the environment.
For the client, this translates into improved indoor comfort, efficient air conditioning in summer, useful supplementary heating depending on conditions, and an outdoor installation that does not compromise the use of the space.
For AirGreen, this project represents exactly what we strive to offer on every job site: a well-thought-out HVAC solution, meticulously installed, and adapted to the building.
Practical advice for homeowners in Baie-D’Urfé
Before installing a wall-mounted heat pump in an area like Baie-D’Urfé, it is recommended to plan the outdoor location at the very beginning of the project. The most discreet location is not always the best technical choice, and the simplest location is not always the most durable.
Winter must also be taken into account. Even if the heat pump is mainly purchased for air conditioning, the outdoor unit remains exposed all year round. Snow, ice, debris, and humidity must be considered from the design of the installation.
Finally, it is preferable to choose a company capable of providing both installation and after-sales service. A well-installed and well-maintained system generally retains better performance over time.
