An HVAC installation where every exterior detail mattered as much as indoor performance
In Dollard-des-Ormeaux, on the west side of Montreal Island, our AirGreen team completed the installation of a GREE LIVO R32 wall-mounted heat pump, a mini split system designed to provide air conditioning, efficient supplemental heating, and seasonal comfort in a residence where the outdoor integration had to be particularly meticulous. The project photo clearly illustrates the context: a red brick facade, a window located directly above the chosen spot, an existing vertical passage on the wall, and a space where the outdoor unit had to be installed without compromising aesthetics or accessibility.
This type of project is exactly the kind of HVAC installation where field experience makes all the difference. Installing a heat pump is not just about mounting an outdoor unit and connecting an indoor unit. You have to consider the building, the necessary clearances, drainage, duct routing, protection of refrigerant lines, the final appearance, and the durability of the installation under the climatic conditions of the Montréal, Laval, Longueuil, North Shore, and South Shore regions.
In this specific case, the brick wall required a methodical approach. Brick is solid, but it demands appropriate anchors, good load distribution, and special attention to avoid unwanted vibrations. The GREE outdoor unit had to be positioned in a stable, secure, and compliant manner, while maintaining reasonable access for future HVAC maintenance.
Why choosing the GREE LIVO R32 was relevant for this residence
The GREE LIVO R32 model is an interesting choice for owners looking for a reliable, compact, and efficient wall solution. It is a wall-mounted heat pump of the mini split air conditioner type, suited to common residential needs: improving comfort in summer, reducing indoor humidity, providing efficient heating during cooler periods, and better controlling the temperature of a specific area of the home.
In a residence in Dollard-des-Ormeaux, where rooms can have temperature variations depending on the building’s orientation, sunlight, insulation, and interior layout, a properly sized wall unit can correct discomfort without necessarily replacing the entire existing heating system. The BTU capacity must always be chosen according to the area, ceiling height, sun exposure, insulation quality, and room use. At AirGreen, we avoid approximate choices: a unit that is too small will constantly work at full capacity, while a unit that is too large risks cycling too often and controlling humidity less effectively.
The R32 refrigerant is also an important point. Compared to some older refrigerants, R32 is recognized for its efficiency and its growing use in new generations of wall systems. In the residential context, it allows manufacturers like GREE to offer efficient units, well suited to current expectations regarding energy efficiency.
A brick facade, a nearby window, and a vertical passage to manage
One of the most interesting aspects of this installation in Dollard-des-Ormeaux was the outdoor location. The GREE unit is installed under a window, on a brick facade, with a vertical line protected by a brown duct cover installed nearby. This choice is not improvised: it meets several practical constraints.
First, the outdoor unit had to be placed at a height and position allowing good air clearance. A wall-mounted heat pump needs to breathe properly. If the warm air expelled in cooling mode or the cold air expelled in heating mode remains trapped around the unit, efficiency can decrease. The location therefore had to preserve enough space in front of the fan and limit immediate obstacles.
Next, the proximity to the window required a clean installation. It was necessary to prevent the refrigerant lines, wiring, or drain from becoming visually intrusive. That is why the vertical passage was organized with a duct cover that protects the ducts while maintaining a neat appearance. On a red brick facade, choosing a brown duct cover helps reduce the visual impact of the installation, especially when it runs along an existing vertical line on the wall.
Finally, the base of the unit had to be securely fixed. Even slight vibrations must be controlled from the start. A sloppy installation can transmit noise to the wall or cause long-term discomfort. Our approach is to use appropriate supports, check alignment, respect clearances, and ensure the whole remains stable over time, even after multiple freeze-thaw, rain, and snow cycles.
Key steps of our HVAC installation in Dollard-des-Ormeaux
For this project, our team followed a precise work sequence, adapted to the building and the installed model.
1. Validation of indoor and outdoor locations
Before drilling or fixing anything, we always validate the location of the indoor and outdoor units. The goal is to achieve good efficiency, convenient access, and a logical path for the ducts. In this case, the outdoor location under the window offered a compact solution, but precise work was needed to maintain a clean finish.
2. Protection of the brick wall and choice of anchors
Brick requires an appropriate anchoring method. We avoid unnecessarily forcing the material and ensure that the fastening points are solid. The weight of the outdoor unit, vibrations, wind, and seasonal variations must all be taken into account.
3. Routing of refrigerant lines and wiring
The refrigerant lines, communication cable, and components necessary for the operation of the wall-mounted heat pump must be routed neatly. The duct cover visible in the photo protects these elements from the weather and provides a professional finish. It is an aesthetic detail but also an important mechanical protection.
4. Vacuuming and technical checks
A mini split installation is not limited to assembly. The refrigeration circuit must be properly prepared. Vacuuming removes air and moisture from the ducts before commissioning. This step is essential for the reliability of the device, the longevity of the compressor, and the overall system performance.
Startup, testing, and explanations to the client
Once the device is connected, we proceed with operational tests in cooling mode and, when conditions allow, in heating mode. We check the unit's response, noise, drainage, communication between the indoor and outdoor units, and basic settings. We then explain to the client how to use the device effectively: recommended temperature, filter maintenance, seasonal use, and best practices.
What this installation shows about the importance of well-planned work
This project in Dollard-des-Ormeaux shows that a good HVAC installation is visible as much in the details as in the performance. An outdoor unit can work, but if it is poorly positioned, poorly protected, or poorly integrated into the building, the client may have to deal with annoyances for years. Conversely, a thoughtful installation makes the system more pleasant to use, easier to maintain, and more harmonious with the home's architecture.
Common mistakes to avoid when installing a wall-mounted heat pump
Many homeowners first compare prices or brands, which is normal. However, the installation itself strongly influences the final result. Here are some common mistakes we often see in the field:
- choosing a BTU capacity without considering insulation, orientation, and the actual use of the room;
- installing the outdoor unit in a space that is too confined, which hinders air circulation;
- neglecting the protection of refrigerant lines;
- using a duct path that is too visible or poorly aligned on a facade;
- forgetting future access for HVAC maintenance;
- underestimating the importance of a complete vacuum and rigorous commissioning;
- mounting the unit on a wall without properly controlling vibrations.
In the case of this residence, the location visible in the photo specifically required avoiding these mistakes. The brick wall, the window, and the vertical elements of the building demanded a disciplined installation. Our goal was to deliver a functional, durable, and neatly integrated system.
Practical advice for homeowners in Dollard-des-Ormeaux and western Montreal
For homeowners in Dollard-des-Ormeaux, Pointe-Claire, Pierrefonds, Kirkland, or Beaconsfield considering a wall-mounted heat pump, several points should be evaluated before installation.
First, you need to determine the area to be treated. An open room, a floor, a living room with large windows, or a bedroom on the second floor do not behave the same way. Then, you need to look at the possible path between the indoor unit and the outdoor unit. The more logical this path is, the cleaner, more efficient, and discreet the installation can be.
Winter must also be considered. Even if the main goal is sometimes air conditioning, a heat pump must be installed taking into account snow, ice, drainage, and accessibility. A device placed too low or in a spot where snow accumulates can cause problems. In many projects on the island of Montreal, in Laval, in Longueuil, on the North Shore, and on the South Shore, we recommend an appropriate height or protection depending on the immediate environment.
Finally, appearance matters. An installation on brick, vinyl, stucco, or a facade visible from the yard requires a choice of routing and finishing. Duct covers, supports, and the unit’s position must be planned from the start, not added as a correction afterward.
Customer experience: more stable comfort and a well-respected exterior
After installing this GREE LIVO R32, the client benefits from a wall system capable of improving comfort in the targeted area, with simple controls and a quick response to temperature changes. The exterior result remains clean: the unit is well positioned, the facade maintains an orderly appearance, and the ducts are protected.
This type of result is especially important in established residential neighborhoods like Dollard-des-Ormeaux, where houses often have brick facades, landscaped backyards, and space constraints. A poorly planned installation can become very noticeable. A well-executed installation integrates with the building and naturally becomes a functional part of the home.

This local knowledge helps us recommend relevant solutions and carry out durable work.
For models like the GREE LIVO R32, we pay special attention to sizing, connection quality, outdoor protection, and commissioning. These are the elements that make the difference between a merely functional installation and a truly professional one.
Grants, efficiency, and eligibility: what to check
Depending on the exact model, chosen capacity, and criteria in effect at the time of installation, some wall-mounted heat pumps may be eligible for financial aid programs or energy grants. Since criteria can change and eligibility often depends on the precise model numbers of the indoor and outdoor units, we always recommend verifying the information at the time of the quote.
At AirGreen, we help our clients understand the necessary documents, the information to keep, and the usual steps to follow after installation. A detailed invoice, model numbers, and required proofs can be part of the file. This support is especially appreciated by owners who want to combine comfort, energy efficiency, and potential financial return.
