A compact, solid, and well-thought-out HVAC installation for an urban building in Plateau-Mont-Royal
In Plateau-Mont-Royal, every HVAC installation requires a precise approach. Access is often tighter, outdoor spaces must be used intelligently, and system integration must respect the building’s performance, aesthetics, and durability. For this project, our AirGreen team installed a GREE VITA R32 wall-mounted heat pump, used as a wall air conditioner, an efficient heating system, and a residential mini split adapted to the realities of a dense Montreal neighborhood.
The installation photo clearly illustrates the type of work we regularly perform: a GREE outdoor unit installed on an elevated support, with particular attention to stability, air clearance, protection of refrigerant lines, and overall finish. In an environment like Plateau-Mont-Royal, where balconies, flat roofs, backyards, and technical passages can be limited, the quality of the outdoor positioning has a direct impact on the system’s long-term performance.
This GREE VITA R32 heat pump was chosen for its 18,000 BTU capacity, Inverter technology, operation with R-32 refrigerant, included WiFi connectivity, and heating capacity down to -25 °C. The 18,000 BTU model sheet specifically lists the numbers GWH18ATDXD-D6DNA3F/I for the indoor unit and GWH18ATDXD-D6DNA4F/O for the outdoor unit, with a cooling capacity of 18,000 BTU, a voltage of 220 V, piping of 1/4 - 1/2 inch, and an outdoor sound pressure of 57 dB(A).
Why the outdoor support was central to this project
In the photo, the outdoor unit is installed on an elevated structure with distribution bases. This choice is not only aesthetic. In an outdoor surface installation, it is necessary to avoid the unit being too close to the ground, accumulating snow, having defrost water remain around the base, or having vibrations unnecessarily transmitted to the building structure.
We therefore paid special attention to four elements:
- mechanical stability of the outdoor unit;
- clearance around the fan to maintain good air exchange;
- protection of the visible refrigerant lines at the back;
- vibration management thanks to a clean and well-leveled support.
This type of detail makes a big difference in a neighborhood like Plateau-Mont-Royal, where installations often have to coexist with architectural constraints, limited surfaces, and condominium or owner requirements. A high-performance wall-mounted heat pump can lose some of its efficiency if the outdoor unit is poorly positioned, poorly supported, or exposed to an accumulation of snow, ice, or debris.
A protected and neatly routed refrigerant line
One of the most visible important elements in this installation is the routing of the lines at the back of the unit. The lines are wrapped and protected, with a routing that follows the building surface neatly. This finishing is essential because the lines carry refrigerant between the indoor and outdoor units. Poor protection can cause premature deterioration of the insulation, loss of efficiency, or condensation problems.
At AirGreen, we pay special attention to the alignment, bending radius, and finishing of the lines. A clean installation doesn’t just mean it looks good in a photo. It also means the system is easier to inspect, simpler to maintain, and better protected against the elements.
In this project, the choice of routing allowed us to keep the functional space around the outdoor unit while ensuring a professional appearance. This is an aspect often underestimated by clients who compare several quotes for a heat pump installation in Montreal, but this is precisely where field experience becomes visible.
The choice of the GREE VITA R32 for year-round comfort
The GREE VITA R32 is designed to offer a good balance between performance, comfort, and budget. The manufacturer presents this series as a solution equipped with a variable-speed compressor, intelligent WiFi control via the GREE+ app, Inverter technology, a wireless remote control, a composite drainage tray, copper/aluminum coils with blue fins tested in salt spray, as well as a refrigerant leak detector.
For housing in Plateau-Mont-Royal, these features have practical value. Buildings can be exposed to significant heat gains in summer, especially on upper floors or in sun-facing rooms. In winter, the need for supplementary heating varies depending on insulation, windows, airtightness, and interior layout. Inverter technology allows the system to modulate its capacity instead of operating only by on/off cycles, which contributes to more stable comfort and better-controlled consumption.
The technical sheet for the 18,000 BTU model indicates a SEER2 of 20.0, a HSPF2 of 8.5, an EER2 of 12.4, a power at -8 °C of 15,300 BTU, and a power at -15 °C of 12,100 BTU. These data help better understand the actual heating performance of the machine, especially in a climate like Montreal, where temperature differences are significant between autumn, winter, and spring.
A device suited for open rooms and Montreal housing
A capacity of 18,000 BTU may be suitable for an open area, a large living room, a main floor, a larger condo, or a space requiring better air distribution. In a building in Plateau-Mont-Royal, pre-installation analysis is particularly important because surface area alone is not enough. We also assess:
- the ceiling height;
- the sun exposure;
- the quality of the windows;
- the presence of load-bearing walls or corridors;
- the distance between the indoor unit and the outdoor unit;
- the electrical constraints;
- the acceptable noise level inside and outside;
- the requirements of the owner, the association, or the condominium.
This step avoids two common mistakes: choosing a machine that is too small, which will run too long without reaching the desired comfort, or choosing a machine that is too large, which may cycle quickly and manage humidity less effectively in summer.
In this case, the choice of the GREE VITA R32 18,000 BTU allowed for a comfortable capacity while keeping a relatively compact outdoor unit, well suited to the available space.
The details that distinguish an AirGreen installation in Plateau-Mont-Royal
Site preparation and surface protection
Before fixing or positioning an outdoor unit, we analyze the support surface. On a membrane, terrace, flat roof, or outdoor structure, uneven load distribution must be avoided. The support visible in the photo rests on a stable solution, with well-distributed support points. This approach helps keep the unit level and limits movement caused by vibrations, wind, snow, or defrost cycles.
A poorly leveled unit can cause noise, accelerate wear on certain components, or hinder normal water drainage. In a professional HVAC installation, the level, clearance, and sturdiness of the support are checked before commissioning.
Air clearance and condenser performance
The front fan of the outdoor unit must be able to expel air without obstruction. In the photo, the unit is clear at the front, allowing the condenser to breathe properly. This clearance is essential to preserve system efficiency, especially on very hot days when the compressor works harder.
In urban installations in Montreal, we often have to deal with walls, guardrails, fences, neighboring equipment, or tight mechanical spaces. Our role is to place the unit in the right spot, without obstructing circulation, without creating heat buildup, and without compromising future access for HVAC maintenance.
Electrical connection and compliance
The GREE VITA R32 18,000 BTU operates on 220 V, with a minimum circuit ampacity of 13 A and a maximum overcurrent protection of 15 A according to the model's datasheet. These values show why a wall-mounted heat pump installation should never be improvised. The electrical connection must be properly sized, adequately protected, and carried out according to applicable standards.
At AirGreen, we prioritize clear coordination between refrigeration and electrical work. This rigor reduces the risk of callbacks, simplifies commissioning, and ensures the customer a ready-to-operate installation under the best conditions.
Commissioning: the step that confirms the quality of the work
Once the indoor and outdoor units are installed, commissioning confirms that the system is working properly. This step includes checking connections, vacuuming, monitoring operating pressures, validating drainage, testing cooling, testing heating, and explaining the main functions to the client.
For a model like the GREE VITA R32, we also take the time to explain the use of the remote control, heating mode, cooling mode, ventilation, dehumidification, and WiFi. Smart control is a real advantage for clients who want to adjust the temperature before coming home, avoid unnecessary heating when they are away, or maintain comfort during the night.
LogisVert subsidy and eligibility to be confirmed at the project stage
The AirGreen sheet for the GREE VITA R32 18,000 BTU model indicates a LogisVert provincial subsidy of $1,836, updated as of November 26, 2025. It also specifies that the model is listed with AHRI 215224737, ENERGY STAR®: No, ENERGY STAR® Cold Climate: No, and ENERGY STAR ID 4511818.
For clients, this means the displayed amount must always be confirmed at the time of submission and installation, as subsidy programs can change. Our role is to help the client understand the necessary documents, the final invoice, the installed model information, and the steps to follow to submit a compliant application.
In the greater Montreal, Laval, Longueuil, North Shore, and South Shore area, subsidies often influence the purchase decision. We therefore include this aspect from the project analysis stage, without leaving the client guessing whether their equipment meets the available criteria.
Mistakes to avoid when installing a mini split in Plateau-Mont-Royal
A mini split installation may seem simple at first glance, but several mistakes can reduce the system's lifespan or cause problems after a few seasons.
Installing the unit too low
An outdoor unit placed too close to the ground can be exposed to snow, ice, and splashes. The elevated support visible in this installation is a practical response to this risk.
Neglecting pipe protection
Poorly protected pipes can deteriorate faster, especially when exposed to sun, frost, and temperature variations. A clean and durable finish is essential.
Choosing capacity based only on area
The area is important, but it’s not enough. Two apartments of the same size can have very different needs depending on their insulation, orientation, floor, windows, and interior layout.
Forgetting access for maintenance
An outdoor unit must remain accessible. A technician must be able to inspect, clean, measure, and intervene without having to dismantle part of the installation. This detail is especially important for urban buildings with limited access.
Comparing prices without comparing the installation method
A cheaper quote may exclude important elements: proper support, pipe finishing, surface protection, complete verification, WiFi configuration, client explanations, or post-installation follow-up. At AirGreen, we focus on a complete, transparent, and durable approach.
Final result: comfort, cleanliness, and reliability
The result of this installation in Plateau-Mont-Royal is a discreet, well-positioned system ready to offer stable comfort in both heating and air conditioning. The outdoor unit is securely installed, the pipes are protected, the space around the fan is clear, and the finish respects the building’s environment.
For the client, the benefit is felt daily: better temperature control, effective air conditioning during hot periods, useful heating during cold days, simplified management thanks to WiFi, and an installation designed to last.
This project reflects our way of working at AirGreen: every heat pump, every wall air conditioner, and every HVAC installation is treated as a complete system. We don’t just install a machine. We analyze the space, adapt the support, protect the pipes, validate the performance, and explain the use to the client.
In a sector like Plateau-Mont-Royal, this rigor is essential. The buildings have their character, constraints, and particularities. A good installation must respect this reality while delivering the expected comfort. This is exactly what this GREE VITA R32 offers: a well-integrated, efficient heating and air conditioning solution adapted to the residential needs of Montreal.

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.

The right pages, at the right time
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
