Generic diagram: wall-mounted heat pump, indoor and outdoor units

In summer, the outdoor unit rejects the house's heat outside.

Generic illustration of this type of installation, not a survey of this job site. Tap a number.

  1. 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.

  2. The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.

  3. Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.

  4. A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.

  5. The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.

  6. On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.

  7. The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.

A neat HVAC installation on a brick wall in Vaudreuil-Dorion

In Vaudreuil-Dorion, a city where residences often combine contemporary architecture, exposed brick walls, open spaces, and highly variable seasonal comfort needs, AirGreen recently installed a GREE AIRY R32 wall-mounted heat pump. This project perfectly illustrates what many homeowners in the region are looking for: a high-performance, discreet, reliable heating and air conditioning solution, installed with meticulous attention to detail.

The outdoor unit, visible in the photo, was installed on a brick wall using robust aluminum wall brackets. This approach frees up ground space, improves air circulation around the unit, and protects the equipment from snow accumulation, debris, stagnant moisture, and freeze-thaw stresses. In an area like Vaudreuil-Dorion, where winters can be cold and summers humid, this configuration is a sound technical choice for maximizing system durability.

The installed GREE AIRY R32 is a wall-mounted heat pump, also known as a mini-split or wall-mounted air conditioner, designed to provide precise indoor comfort while maintaining controlled energy consumption. At AirGreen, we know that choosing a unit isn't just about brand or price: it's essential to consider the building's structure, insulation, room orientation, installation constraints, exterior finish quality, and daily user experience.

A GREE AIRY R32 unit adapted to modern residential needs

The GREE AIRY R32 range stands out for its balanced approach between efficiency, comfort, quiet operation, and the use of a new-generation refrigerant. R32 is increasingly used in modern heat pump systems, notably because it allows for excellent energy performance with a reduced environmental impact compared to several previous generations of refrigerants.

In the case of this installation in Vaudreuil-Dorion, the client sought a solution capable of stabilizing the indoor temperature during hot periods while offering reliable heating in autumn, spring, and a good part of winter. A GREE wall-mounted heat pump responds very well to this type of need, especially when it is correctly sized and installed by a specialized HVAC team.

An important point for homeowners in Montreal, Laval, Longueuil, the North Shore, and the South Shore: the actual performance of a mini-split depends as much on the unit as on the quality of the installation. Improper mounting height, poorly planned condensate drainage, inadequately protected refrigerant lines, or an outdoor unit placed in too confined a space can impair the system's performance, comfort, and lifespan. For this project, we therefore paid particular attention to ventilation around the unit, the solidity of the supports, the protection of connections, and the overall finish.

A clean, stable, and well-ventilated outdoor installation

The photo shows several important elements of a carefully executed HVAC installation. The GREE outdoor unit is fixed on metal wall brackets, with blue anti-vibration pads placed between the base of the unit and the support rails. These components reduce the transmission of vibrations to the building structure, an essential aspect when equipment is installed directly on a facade.

On a brick wall, improvisation must be avoided. The fastening must be solid, aligned, and adapted to the load of the unit. Anchors must be precisely installed to ensure long-term stability, especially during repeated heating and cooling cycles. The supports must also allow sufficient clearance beneath the unit, which facilitates defrost water drainage and future maintenance.

In this project in Vaudreuil-Dorion, the available space on the exterior wall allowed for clear and efficient integration. The unit is positioned to promote good airflow in front of the fan and on the side of the coil. This airflow is essential: an outdoor unit too close to an obstacle or installed in a confined area risks losing efficiency, running longer, and generating more wear.

Protected refrigerant lines for a durable finish

Below the unit, insulated and neatly grouped refrigerant lines are visible. These lines circulate refrigerant between the indoor and outdoor units. Their installation requires great precision, as they play a direct role in the system's performance. A poorly insulated, improperly bent, or unnecessarily exposed line can lead to efficiency losses and long-term problems.

At AirGreen, we place great importance on protecting refrigerant lines, condensate drainage, and communication wiring. The goal is twofold: to ensure optimal performance and to provide a clean exterior appearance. In a home in Vaudreuil-Dorion, as in residential areas of Montreal, Laval, Longueuil, the North Shore, and the South Shore, the visible finish matters greatly. A good HVAC system must be efficient, but it must also be installed in a way that respects the building's aesthetics.

In this specific case, the white brick and aluminum wall mount create a visually discreet ensemble. The installation does not overload the facade, and the unit is placed at a convenient height for maintenance while being high enough to avoid ground accumulations.

Why the GREE AIRY R32 is an excellent choice for Vaudreuil-Dorion

A wall-mounted heat pump designed for daily comfort

The GREE AIRY R32 is designed to provide stable temperatures without sudden fluctuations. Thanks to Inverter technology, the compressor adjusts its operation according to the actual needs of the home instead of simply starting and stopping at full capacity. This modulation allows for better comfort, reduced short cycling, and more stable energy consumption.

For occupants, this means gentler air conditioning in summer and more consistent heating during colder seasons. A properly installed wall-mounted heat pump avoids unpleasant temperature swings, particularly in open-plan areas, living rooms, master bedrooms, home offices, or upstairs spaces.

In Vaudreuil-Dorion, several homes have areas exposed to the afternoon sun or rooms that are more difficult to balance with an existing central system. A mini-split heat pump can then become a very effective solution for improving comfort without undertaking major ductwork.

R32: a modern and efficient refrigerant

One of the most interesting technical elements of this installation is the use of R32 refrigerant. This refrigerant is now very present in new generations of wall-mounted air conditioners and heat pumps due to its good thermodynamic properties. It allows manufacturers to design efficient appliances while meeting stricter expectations regarding environmental impact.

For a homeowner, this means investing in more current technology, better aligned with the evolution of the HVAC market. It's not just a technical detail: the choice of refrigerant can influence future equipment availability, maintenance, performance, and the overall value of the installation.

An installation eligible for subsidies according to the model and current criteria

Several models of GREE wall-mounted heat pumps may be eligible for subsidy programs, especially when the unit meets the required energy efficiency criteria. For homeowners in Vaudreuil-Dorion, as for those in Montreal, Laval, Longueuil, the North Shore, and the South Shore, this possibility can significantly reduce the net cost of the project.

At AirGreen, we help our clients understand the eligibility conditions, required documents, and steps to follow after installation. The detailed invoice, model numbers, technical information, and proof of installation are essential elements to correctly complete a subsidy application. We always recommend validating the exact eligibility of the model at the time of submission, as programs may be updated.

Specific challenges of this project

Every installation has its constraints. In this case, the exterior brick wall required precise, clean, and durable fastening. It was also necessary to consider the available space, the trajectory of the refrigerant lines, the positioning of the supports, and future accessibility for HVAC maintenance.

One of the common mistakes we observe in some installations is choosing a location that is too low or too exposed to snow accumulation. Here, wall mounting avoids several typical problems: obstruction by snow, contact with stagnant water, risk of impact with gardening tools, or leaf accumulation around the base. This decision improves equipment durability and facilitates cleaning around the unit.

Another important point concerned vibration management. The anti-vibration pads visible under the unit help limit noise transfer to the structure. This is particularly relevant when the outdoor unit is fixed to the building rather than installed on a ground-level base.

A finish that facilitates future maintenance

A good wall-mounted heat pump installation should not only be designed for the day of installation. It should also allow for easy maintenance in the following years. Access to the service panel, visibility of connections, clearance around the outdoor coil, and stability of the supports directly influence the ease of intervention.

For this project in Vaudreuil-Dorion, our team maintained a clear, accessible, and professional configuration. This will allow technicians to more easily check the unit's condition, clean the coil, inspect connections, and examine the entire system during periodic maintenance.

Regular HVAC maintenance is highly recommended to preserve a heat pump's efficiency. It helps maintain good airflow, prevent dust buildup, quickly detect anomalies, and extend the system's lifespan. A high-performing unit that is poorly maintained gradually loses efficiency, which can increase electricity consumption and reduce comfort.

Practical advice for homeowners considering a similar installation

Before installing a GREE AIRY R32 heat pump or any other wall-mounted air conditioner, it is important to consider several points:

  • Proper sizing: a unit that is too small will run too long, while a unit that is too large can create short cycling and less stable comfort.
  • Indoor unit location: choose a wall that allows for good air diffusion without blowing directly on occupants.
  • Outdoor unit location: ventilation, noise, maintenance access, and snow protection must be evaluated.
  • Quality of supports: a wall-mount must be stable, secure, and adapted to the type of exterior cladding.
  • Condensate management: water drainage must be properly planned to avoid backflows, stains, or undesirable accumulations.
  • Final appearance: ducts, lines, and protections must be neatly installed to preserve the building's aesthetics.

These details may seem secondary, but they often make the difference between an average installation and one that is durable, efficient, and pleasant to use.

The AirGreen approach: precision, transparency, and field experience

At AirGreen, we carry out installations of wall-mounted heat pumps, wall-mounted air conditioners, and mini-split systems throughout the greater Montreal area, including Laval, Longueuil, the North Shore, the South Shore, and rapidly growing areas like Vaudreuil-Dorion. Our approach is based on a concrete evaluation of the building, tailored recommendations, and installation in accordance with the best HVAC industry practices.

We know that customers don't just want to buy a machine. They want a reliable, well-installed, quiet, efficient, and easy-to-maintain solution. In this project, the installation of the GREE AIRY R32 met these expectations with a solid and visually clean configuration.

This type of installation is particularly suitable for homeowners who wish to improve their comfort without replacing their entire existing system. It can also serve as a primary solution in certain areas, as supplemental heating in a hard-to-cool room, or as an effective complement to an existing heating system.

Final result: a well-integrated GREE AIRY R32 heat pump ready for Quebec's seasons

The final result of this installation in Vaudreuil-Dorion is a well-positioned, stable system ready to provide constant comfort. The outdoor unit is securely fixed, the lines are protected, vibrations are reduced, and the entire setup meets the practical requirements for a durable installation in Quebec.

For the client, the benefits are tangible: better air conditioning during hot days, efficient auxiliary heating during cooler periods, quiet operation, controlled energy consumption, and modern equipment using R32 refrigerant.

For AirGreen, this project represents exactly the type of intervention we love to carry out: a clean, technical, thoughtful, and building-adapted HVAC installation. Every detail matters, from model selection to exterior finishing. A well-installed GREE AIRY R32 wall-mounted heat pump can provide years of comfort, provided that the installation is carried out rigorously from the start.
