An HVAC installation in Candiac where every centimeter counted
In Candiac, on the South Shore, our AirGreen team carried out the installation of a GREE VITA R32 wall-mounted heat pump, also called a wall air conditioner or mini split, in a particularly challenging outdoor setting: the condenser unit had to be positioned under an existing structure, near a concrete foundation wall, with limited clearance above and a narrow technical passage on the right side.
This type of installation requires much more than just placing equipment. To ensure lasting performance, quiet operation, and good accessibility for HVAC maintenance, we must analyze the immediate environment: air circulation around the unit, protection against snow buildup, ground level, support stability, routing of refrigerant lines, and visual integration around the house.
In this project, the GREE VITA R32 was installed on an elevated outdoor support, itself resting on solid blocks. This setup keeps the unit off the ground, reducing risks related to moisture, fallen leaves, ice, and small debris accumulation. The choice of support is especially important in a city like Candiac, where winters can expose outdoor equipment to repeated cycles of freezing, thawing, wet snow, and humidity.
Why the GREE VITA R32 was well suited for this residence
The GREE VITA R32 is a popular solution for residences in the greater Montreal area, especially in Laval, Longueuil, on the North Shore and the South Shore, because it meets several concrete expectations of homeowners: efficient air conditioning in summer, supplementary or primary heating depending on the house layout, quiet operation, Inverter technology, and use of R32 refrigerant.
For a typical residential configuration of 12,000 BTU, the GREE VITA R32 technical sheet notably indicates a cooling capacity of 12,000 BTU, heating operation down to -25 °C, refrigerant gas R32, included Wi-Fi, an efficiency rating of 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), as well as a 10-year warranty on parts and compressor under applicable conditions.
This data is important, but it never replaces on-site analysis. A successful HVAC installation depends as much on the machine as on its location, the thermal load calculation, the length of refrigerant lines, drainage, electrical connection, and the quality of commissioning.
The main challenge: installing under a structure without compromising ventilation
The project image clearly shows an outdoor unit installed under a wooden structure, with limited overhead clearance. This situation is not uncommon in homes in Candiac, Brossard, La Prairie, Saint-Constant, or Longueuil, where backyards often feature balconies, porches, terraces, or architectural overhangs.
The main risk in this type of location is to hinder the airflow of the outdoor unit. A heat pump must be able to properly draw in and expel air. If the warm air in cooling mode, or the cold air in heating mode, remains trapped around the unit, the system can lose efficiency, work harder, and reduce its actual comfort indoors.
Our approach therefore consisted of validating several points before the final installation:
- the clearance in front of the fan grille;
- the available space on the sides;
- the usable height under the structure;
- the stability of the ground;
- future access for cleaning and service;
- the routing of the refrigerant pipes and wiring;
- the protection of the pipes with a clean and well-positioned line cover.
The decision to use an elevated support allowed for a clean, stable, and more durable installation than placing it directly on the ground.
A solid, clean outdoor installation designed for maintenance
The outdoor unit is installed on a white metal base, well aligned with the machine's facade. The feet rest on concrete blocks, which improves stability while limiting direct contact with the ground. This method reduces vibrations and facilitates natural drainage around the unit.
At AirGreen, we pay special attention to this type of detail because a poorly leveled support can create vibrations, unwanted noise, or premature wear. A wall-mounted heat pump must not only work well on the day of installation. It must remain stable, accessible, and reliable for many years.
In this project in Candiac, the line cover visible on the right side protects the refrigerant pipes and provides a cleaner finish. This part of the installation is often underestimated by homeowners, but it plays an essential role. Poorly protected pipes can be exposed to UV rays, shocks, water infiltration, or movements related to freezing. Careful routing reduces risks and improves the overall appearance of the installation.
A wall-mounted heat pump adapted to the real needs of the house
The choice of a heat pump should never be limited to the brand name or BTU capacity. A unit that is too small will run too long and struggle to maintain the temperature. A unit that is too large can produce short cycles, reduce dehumidification, and create discomfort.
For this installation in Candiac, our work involved taking several factors into account:
Interior layout
A wall-mounted heat pump must be positioned to distribute air efficiently. In an open area, it can cover a living room, dining room, and kitchen. In a house with more closed-off rooms, air circulation between rooms must be evaluated.
Sun exposure
In Candiac, several houses have large windows, patio doors, or very bright back spaces. Solar gain directly affects the air conditioning load in summer. A very exposed room may require a better-sized unit or a different distribution strategy.
Insulation and the age of the property
A recent, well-insulated house does not have the same needs as an older property. We always adjust our recommendations based on the building’s reality, not just the surface area.
Daily use
Some clients mainly want air conditioning during heatwaves. Others want to use the heat pump as a regular heating source for much of the winter. The GREE VITA R32 is designed to provide heating down to -25 °C, making it suitable for the Quebec climate when installation and sizing are done correctly.
What this installation in Candiac teaches South Shore homeowners
This installation perfectly illustrates a reality on site: the available location is never 100% ideal, but an experienced installer knows how to turn a constraint into a reliable solution.
Mistake to avoid: placing the outdoor unit too close to the ground
An outdoor unit placed too low can quickly become vulnerable. In winter, snow, ice, and meltwater can impair operation. In summer, leaves, dust, and moisture can accumulate around the base. In the long term, this complicates maintenance and can reduce the lifespan of certain components.
The elevated support used here is a good practice. It keeps the unit cleaner, facilitates access underneath the device, and helps maintain a more stable environment around the heat pump.
Mistake to avoid: ignoring clearances around the unit
Under a gallery or near a foundation wall, caution is necessary. An installation that is too recessed can harm heat exchange. The unit must be able to breathe. That is why we always carefully assess the location before fixing the unit.
In this project, the unit's facade remains well cleared, which promotes air discharge by the front fan. The lateral positioning of the pipes also helps keep the whole setup clean without blocking critical areas.
Mistake to avoid: neglecting the finishing of refrigeration lines
A visible refrigeration line, poorly aligned or poorly protected, can harm the appearance of the house. It can also become a weak point if exposed to the elements. The white line cover used in this installation blends well with the outdoor environment and protects the essential technical components.
For our clients in Montreal, Laval, Longueuil, North Shore and South Shore, this finish often makes the difference between a simply functional installation and a truly professional installation.
R32: a modern choice for a residential wall-mounted heat pump
The GREE VITA R32 uses the refrigerant R32, a technology increasingly present in residential air conditioning and heating systems. This gas is often chosen for its better environmental profile compared to some older refrigerants and for its efficiency in modern Inverter compressor systems.
For homeowners, this translates into a device designed according to current market standards. For the installer, it requires careful handling, compliant with applicable standards. At AirGreen, we always remind that a system containing refrigerant must be installed and commissioned by qualified professionals.
Built-in Wi-Fi and everyday comfort
The Wi-Fi included on the GREE VITA R32 is a tangible advantage. Occupants can adjust the temperature remotely, prepare the home before their return, avoid heating or cooling unnecessarily during an absence, and adapt settings according to their schedule.
In a residence in Candiac, this flexibility is especially convenient for families with variable schedules. The heat pump can be programmed to maintain stable comfort without running unnecessarily at full power.
LogisVert Subsidy: a point to verify before purchase
Subsidy programs are an important factor when choosing a wall-mounted heat pump in Quebec. Hydro-Québec indicates that for heat pumps installed from November 26, 2025, the devices must be ENERGY STAR certified to be eligible for financial aid, and recommends using the official search tool to check the list of eligible heat pumps.
For AirGreen clients, this means always validating the exact model, the indoor and outdoor unit numbers, the installation date, and the program conditions before confirming the applicable amount. Hydro-Québec also specifies that the application is made through the LogisVert portal and that financial aid is processed after the file is submitted.
Our role is to help owners avoid common mistakes: choosing an ineligible model, confusing two variants of the same device, forgetting a required document, or relying on outdated information.
What the client gets after a well-executed installation
Once the GREE VITA R32 is installed and commissioned, the client benefits from a system capable of meeting the essential needs of a modern home:
- effective air conditioning during hot and humid periods;
- efficient heating during much of the cold season;
- quiet operation indoors;
- remote control via Wi-Fi;
- better management of electricity consumption;
- stable and clean outdoor installation;
- easy access for HVAC maintenance.
The visible result outside is simple and professional: a well-centered unit, installed on a solid support, with protected piping and finishing adapted to the existing environment.
The importance of HVAC maintenance after installation
Even a well-installed heat pump needs maintenance. We recommend that owners regularly clean the indoor filters, keep the outdoor unit clear, monitor leaf or snow buildup, and schedule professional maintenance as needed.
In a location like this, under a structure, periodic inspection is especially useful. It is important to ensure that air always circulates properly, that the support remains stable, and that nothing obstructs the unit throughout the seasons.
Good HVAC maintenance helps preserve performance, reduce the risk of unusual noises, and extend the equipment's lifespan.
