A precise outdoor wall installation in a tight space in Boisbriand
In Boisbriand, on the North Shore, AirGreen completed an installation of a GREE VITA R32 wall-mounted heat pump in a typical residential building context where outdoor space must be used smartly. The photo shows an outdoor unit installed directly on a brick facade, above a lower opening and below a large window. This type of location requires careful execution, as the unit must be perfectly stable, accessible, well cleared, and securely attached to a structure capable of supporting its weight over the long term.
This installation was not a simple standard placement. The brick wall, the presence of a window immediately above, the proximity of the foundation, nearby openings, visible cable routing, and the electrical disconnect box to the right of the unit required precise planning. At AirGreen, we chose a wall-mounted configuration on reinforced metal supports, with aligned anchor points, level control, respected front clearance, and organized connections to preserve both the machine's performance and the facade's appearance.
The client was looking for a reliable solution to improve indoor comfort without cluttering the yard or installing the unit on the ground. In several properties in Boisbriand, as well as in Montreal, Laval, Longueuil, on the North Shore and the South Shore, the available space around the building is sometimes limited by access points, basement windows, side passages, setback margins, or outdoor landscaping. Wall installation then becomes a very relevant option, provided it is carried out methodically.
Why install the outdoor unit on the wall rather than on the ground
In this project, the choice of the wall mount met several practical objectives. A ground installation could have obstructed access, been too close to an opening, or been exposed to the accumulation of snow, leaves, and debris. By placing the outdoor unit higher up, we freed up space at the base of the wall while reducing some risks related to winter conditions.
A wall-mounted heat pump installed on the wall offers several advantages when well positioned:
- it remains clearer during snow accumulation;
- it takes up less ground space;
- it facilitates outdoor layout;
- it reduces the risk of accidental impact with objects, tools, or garden equipment;
- it allows for a clean connection when the indoor unit is located on the other side of the wall or nearby;
- it can improve access to components during HVAC maintenance.
However, this choice requires very good technical expertise. A brick wall should never be treated as a simple mounting surface. The supports must be installed with appropriate anchors, the load points must be consistent, and the whole must remain stable despite vibrations, wind, frost, thaw, and prolonged compressor use.
A brick facade that required serious anchoring
The photo clearly shows the red brick facade and concrete foundation. The GREE VITA R32 unit is mounted on two triangular metal supports, each anchored to the wall. This type of installation is often used for residential mini splits, but its success depends entirely on the quality of the installation.
We paid special attention to three elements:
- The strength of the anchoring: the supports must withstand the weight of the outdoor unit and repeated stresses.
- The level of the device: a poorly leveled unit can cause vibration, drainage, or wear problems.
- Vibration isolation: the supports and contact points must limit noise transmission to the wall.
On this site in Boisbriand, the unit was positioned to maintain sufficient clearance in front of the fan while avoiding blocking the window above. The chosen height also preserves access to the electrical box and connections, an essential point for any future intervention.
A GREE VITA R32 adapted to residential needs
The GREE VITA R32 is a single-zone wall heat pump designed to provide cooling and heating in a targeted area. In the 12,000 BTU 220V version distributed by AirGreen, the technical sheet notably indicates a cooling capacity of 12,000 BTU, the refrigerant R-32, included Wi-Fi, an efficiency SEER2 of 19.0, an HSPF2 of 8.5, an indoor noise level of 22 to 47 dB(A), an outdoor noise level of 52 dB(A), a power supply of 220 V, as well as a warranty of 10 years on parts and compressor. The same sheet also specifies the indoor and outdoor model numbers, the AHRI, capacity at -8 °C and -15 °C, as well as the dimensions of the outdoor unit.
These technical details are important for owners comparing several options of wall air conditioner, heat pump, or mini split. The purchase price alone is not enough to judge the value of a system. It is also necessary to understand the actual capacity, seasonal performance, noise level, type of refrigerant, electrical supply, warranty, and especially the quality of the installation.
In Boisbriand, the client needed an efficient but also discreet system. The VITA R32 met this demand well thanks to its compact size and inverter operation, which allows performance to be adjusted according to demand rather than operating only in abrupt on and off cycles.
R-32: a technical detail visible even on the label
On the label of the outdoor unit visible in the photo, you can see the mention related to R32 and the A2L classification. This highlights an essential point: recent HVAC equipment requires installation compliant with the rules applicable to the refrigerant used. R-32 is present in several new generations of wall-mounted heat pumps and demands professional handling.
For the client, this means it’s not just a simple device to plug in. Refrigerant connections, vacuum pulling, sealing, pipe insulation, joint protection, and commissioning must be performed by qualified technicians. Poor procedures can reduce performance, increase leak risks, or compromise the compressor’s lifespan.
At AirGreen, we treat every HVAC installation as a complete system: indoor unit, outdoor unit, piping, drain, power supply, control, mechanical support, clearances, and operational checks.
The disconnect box: a discreet but essential element
To the right of the outdoor unit, you can see an electrical box installed nearby. In a wall-mounted heat pump installation, the outdoor disconnect is an important element for safety and service. It allows the unit to be isolated during intervention, maintenance, or repair.
Its location must be accessible without hindering the unit’s operation. In this project, we ensured that the electrical connections were neatly organized and that access remained convenient. A successful outdoor installation should not force a technician to navigate obstacles or work in a risky position.
The proximity between the unit and the disconnect box also helps maintain a compact configuration. On a brick facade like this one, the goal is to limit visual clutter while following good installation practices.
Technical choices that turn a wall-mounted installation into a durable setup
Clearance around the outdoor unit
An outdoor unit must be able to exchange air efficiently. The front fan of the GREE VITA R32 must not be obstructed, and the sides must remain accessible for inspection and HVAC maintenance. In this installation in Boisbriand, the unit was placed under the window but with enough distance not to hinder air exhaust or create an excessive recirculation zone.
Air recirculation is a common problem in poorly planned installations. If the air expelled by the unit is taken back too quickly by the coil, the system works harder, consumes more, and loses efficiency. This problem can occur when the unit is too close to an opposite wall, stuck in a narrow passage, or installed under a balcony without adequate clearance.
Here, the facade offers an open front clearance, allowing the fan to operate properly. The wall positioning also helps reduce exposure to certain debris on the ground.
Reducing vibrations on a brick structure
Vibrations are an important issue in wall installations. An outdoor unit installed on a poorly fixed support can transmit a humming through the wall, especially when the device is running in heating mode or during defrost cycles. In a house, this can become irritating for the occupants, even if the unit is technically functional.
For this reason, we paid attention to the stability of the supports, the level of the device, and the quality of the support points. The triangular supports visible in the image help distribute the load and keep the unit in place. The supports under the device’s feet also help limit direct vibrations.
In several projects carried out by AirGreen in Laval, Montreal, Longueuil, on the North Shore and the South Shore, we found that acoustic comfort depends as much on the installation as on the noise level listed on the technical sheet. A device advertised as quiet can become unpleasant if it is poorly installed; conversely, a well-executed installation greatly improves the daily experience.
The routing of the lines and protection of the fittings
In this installation, the fittings and lines are located on the right side of the unit, near the wall. This area must remain clean, accessible, and protected. The refrigerant lines carry the refrigerant between the indoor and outdoor units. They must be well insulated, secured without excessive tension, and oriented to avoid unnecessary bends.
In a brick facade context, the penetration to the interior must be done precisely. Damage to materials must be avoided, good sealing ensured, and condensation drainage planned on the interior side. A sloppy installation can lead to leaks, performance losses, or costly repairs.
At AirGreen, we plan the routing of the lines from the start. The final result must be reliable but also visually clean. A heat pump installed on a visible facade should blend as well as possible with the building, especially in a residential area like Boisbriand.
Subsidies and eligibility: verify the exact model
Homeowners in Boisbriand who choose a wall-mounted heat pump often want to know if their device may be eligible for financial assistance. Hydro-Québec’s LogisVert program offers aid for certain energy efficiency measures, including eligible heat pumps. Hydro-Québec also states that its search tool allows you to assess the amount offered using the heat pump’s model number or AHRI number.
For the GREE VITA R32 12,000 BTU 220V version, the AirGreen page indicates a LogisVert provincial subsidy of $1,164, updated on November 26, 2025, with AHRI 215402236 and the associated model numbers. Since programs, criteria, and eligible lists can change, we always recommend verifying the amount at the time of purchase and keeping all necessary documents: invoice, proof of installation, indoor and outdoor model numbers, AHRI, and technical information.
The subsidy should never replace a proper HVAC analysis. The right device remains the one that meets the building's needs, thermal load, desired comfort, and installation constraints. Financial aid then helps improve the overall project cost when the criteria are met.
Mistakes to avoid for a similar installation
This project in Boisbriand highlights several points that owners should check before accepting a wall-mounted heat pump installation on a brick facade.
Here are the most common mistakes:
- choosing a location only because it is quick to install;
- mounting the unit on a wall without checking the quality of the anchoring;
- installing the device too close to a window, balcony, or obstacle;
- neglecting access to the electrical box or connections;
- leaving exposed pipes without adequate protection;
- underestimating vibrations transmitted to the building;
- forgetting future maintenance;
- choosing a BTU capacity without analyzing the room or the served area.
In this project, every decision was made to avoid these problems. The unit is stable, clear, installed on suitable supports, with an accessible disconnect box and a compact configuration. This rigor is essential to ensure lasting performance.
The indoor comfort sought by the customer
Behind this outdoor unit installed on the facade, there is a very concrete need: to improve the comfort of an indoor area without major work. A GREE VITA R32 in mini split configuration allows efficient cooling during the summer and provides heating according to the needs and limits of the chosen model. For a house or apartment in Boisbriand, this type of solution is particularly useful when certain rooms become too hot, when the existing system does not distribute air well, or when one wants to reduce the use of noisy portable devices.
The wall-mounted heat pump also offers more precise temperature control. The customer can adjust the specific area without changing the entire building. This targeted comfort is one of the major advantages of wall systems, especially in homes where needs vary from one floor or room to another.
Local expertise for the North Shore and Greater Montreal
AirGreen regularly works on the North Shore, notably in Boisbriand, Blainville, Rosemère, Sainte-Thérèse, Laval, and neighboring municipalities. Our experience in Greater Montreal allows us to adapt our installations to a wide variety of buildings: brick facades, concrete foundations, plexiglass, single-family homes, condos, buildings with restricted access, flat roofs, and narrow side yards.
This installation of GREE VITA R32 Wall-Mounted Heat Pump – Air Conditioner – Mini Split in Boisbriand clearly illustrates our approach: assess the building, choose the most logical location, install securely, protect connections, respect clearances, and plan for maintenance. These are the details that distinguish a durable installation from a merely functional setup.
For clients in Montreal, Laval, Longueuil, the North Shore, and the South Shore, this project also demonstrates the importance of comparing contractors by more than just price. A well-done HVAC installation protects the machine, the building, comfort, and the client's investment.
A clean, stable result designed to last
The final result is a compact outdoor installation well integrated into the facade. The GREE VITA R32 unit is securely mounted on wall brackets, well aligned under the window, clear at the front, and accompanied by an accessible electrical disconnect. Choosing a wall-mounted installation helps preserve ground space while better protecting the unit against certain winter constraints.
In Boisbriand, this installation exactly meets the client's expectations: improved indoor comfort, modern solution, clean appearance, rigorous execution, and configuration adapted to an existing building. At AirGreen, we believe a good HVAC installation is judged as much by the visible details as by those that are not seen: anchoring, sealing, commissioning, drainage, electrical safety, pipe protection, and ease of maintenance.
