A GREE VITA R32 installation in Deux-Montagnes in a tight outdoor space, between foundation, brick, and balcony
This installation carried out in Deux-Montagnes, on the North Shore, highlights a type of HVAC project where the quality of the result depends as much on the choice of the machine as on how it is integrated into the building. The client wanted to improve indoor comfort with a GREE VITA R32 wall-mounted heat pump, used both as a wall air conditioner in summer and as an efficient heating system in mid-season and during cold periods, according to the home's needs.
The construction site photo shows a very concrete constraint: the GREE outdoor unit is installed near a basement door, under a wooden balcony structure, against a concrete foundation, and near a brick wall. The duct passage is visible in a brown line cover on the brick, then in a gray vertical downpipe to the outdoor unit. This type of installation requires careful planning to ensure a clean finish, maintain the necessary clearances around the device, preserve access to the door, and prevent the system from becoming a nuisance for the occupants.
At AirGreen, we often see this kind of configuration in Deux-Montagnes, Sainte-Marthe-sur-le-Lac, Saint-Eustache, Laval, Montreal, Longueuil, and in several areas of the South Shore. Houses are sometimes enlarged, renovated, or built with narrow exterior accesses. A standard installation is not always enough. The method must be adapted to the building without compromising performance or future maintenance.
The main challenge: install the outdoor unit without blocking access to the basement
The outdoor unit is placed right next to a white door leading to the basement or a service area. This location was not chosen at random. It shortens the route of the refrigerant lines, keeps a direct logic between the inside and outside, and limits the visual impact on the facade. However, it was absolutely necessary to preserve the door opening and avoid creating a dangerous obstacle in the passage.
Our team therefore worked with three priorities:
- maintain convenient access to the door;
- ensure sufficient frontal clearance in front of the outdoor unit's fan;
- Protect the ducts with a solid finish consistent with the existing wall.
The outdoor unit’s fan must be able to expel air freely. In this project, the front area remains clear despite the presence of the balcony and the wooden structure on the right. This is an essential point: a unit cramped in a poorly ventilated corner can lose efficiency, become noisier, and work harder during heating or cooling cycles.
A neat finish thanks to the line cover on brick and foundation
The passage of ducts is one of the most visible aspects of a mini split installation. On this house in Deux-Montagnes, the red brick and gray foundation created two very different surfaces. A white or poorly aligned duct would have caught the eye. So we used a more structured routing: a horizontal brown section on the brick, then a vertical gray drop along the foundation.
This detail is important for two reasons. First, the line cover protects the technical elements: refrigeration piping, insulation, communication wiring, and drainage depending on the configuration. Second, it gives the whole installation a neater appearance. A residential HVAC installation must work properly, but it must also respect the property's appearance.
In areas like Montreal, Laval, Longueuil, North Shore, and South Shore, many customers ask us for a discreet installation. They want an efficient heat pump without the ducts dominating the facade. In this project, the line cover follows the building’s lines and limits the visual impact of the connection.
The GREE VITA R32: a choice suited to the residential needs of the North Shore
The GREE VITA R32 is a wall-mounted heat pump designed for residential installations where a simple, efficient, and well-integrated solution is sought. The VITA R32 series is available in several capacities, including 9,000, 12,000, 18,000, and 24,000 BTU, allowing the system to be adapted to the area to be cooled or heated. GREE Canada also lists features for this range such as Inverter technology, Wi-Fi connectivity, R32 refrigerant, a refrigerant leak detector, and coils with Blue Fin treated fins.
For an owner in Deux-Montagnes, this flexibility matters a lot. A house on the North Shore may have an open area on the ground floor, a finished basement, a room above a garage, or an extension that is harder to temper. The same capacity does not suit all situations. At AirGreen, we assess the area, insulation, windows, solar orientation, ceiling height, and actual room use before confirming the sizing.
The public technical sheet for the VITA series notably indicates efficiencies that vary according to capacity and voltage. As a reference, the 18,000 BTU version at 230 V shows published values of SEER2 20, EER2 12.35, HSPF2 8.5, and COP 3.9, while other capacities in the range have their own values. This data helps compare options, but it never replaces building analysis. A well-performing heat pump that is poorly sized can disappoint, even if it looks good on paper.
Why R32 is relevant in a recent installation
The VITA R32 model uses the R32 refrigerant, making it a consistent choice for owners who want to install a newer system better aligned with current HVAC market trends. The interest is not only environmental. R32 is also associated with systems designed to offer good energy efficiency, with compact equipment suitable for residential projects.
GREE and other distribution sheets indicate that the VITA R32 can provide heating down to very cold outdoor temperatures and air conditioning during intense heat, depending on installation conditions and the chosen capacity. The published ranges notably mention heating operation down to about -25 °C and air conditioning up to about 48 °C for the series. For a city like Deux-Montagnes, where winters are harsh and summers are humid, this type of operating range is a concrete advantage.
A stable outdoor base to limit vibrations and protect the building
The outdoor unit is installed on a concrete pad near the foundation. In a confined space like this, base stability is essential. An outdoor unit that moves, vibrates, or rests on an uneven surface can generate noise, prematurely wear certain components, and make maintenance more difficult.
We therefore pay special attention to:
- stability of the support;
- leveling of the unit;
- distance from walls and obstacles;
- protection of refrigerant lines;
- drainage of water produced during defrost cycles;
- access to service panels.
Under a wooden balcony, these factors become even more important. It is necessary to prevent water from accumulating near the structure, compacted snow from blocking the unit, or the fan from blowing air into a too confined area. The final location must consider the client’s daily life, not just ease of installation.
Managing drainage and snow in Deux-Montagnes
On the North Shore, outdoor installations must be planned for winter. A heat pump operating in heating mode produces water during defrost cycles. This water must be able to drain without creating a dangerous ice zone near a door or passage.
In this installation, the proximity to the basement entrance required special attention. Our team checked that the unit would not create an obstacle in the access path and that the space around the machine could be maintained during winter. The client also received simple advice: keep the front of the unit clear, remove snow accumulations without hitting the grille, and avoid storing objects around the compressor.
Regular HVAC maintenance also helps ensure that the coils stay clean, drains are not blocked, and the unit maintains good efficiency.
Grants: eligibility to be verified according to the exact model
Homeowners who install a wall-mounted heat pump often ask if their project might be eligible for financial assistance. Hydro-Québec’s LogisVert program offers aid for the purchase and installation of certain ENERGY STAR certified cold climate wall-mounted heat pumps; eligibility and amounts must, however, be verified with the exact model numbers and the rules in effect at the time of the application.
At AirGreen, we provide the customer with the necessary information on the invoice and help them identify important details: brand, model, capacity, indoor unit, outdoor unit, and installation date. This step prevents common mistakes, such as submitting the wrong model number or confusing the commercial series with the installed combination.
What this installation in Deux-Montagnes reveals about a truly successful HVAC installation
An installation like this may seem simple at first glance: an outdoor unit, a brick wall, a line cover downspout, and a well-positioned GREE machine. In reality, it summarizes several technical decisions that directly impact comfort, reliability, and the final appearance of the project.
Key steps carried out by our team
We first assessed the outdoor area to confirm that the device could be installed without obstructing basement access. The wooden balcony, black railing, brick wall, foundation, and door formed a tight set of constraints. Once the location was validated, we planned the line route to reduce unnecessary lengths and protect the exterior finish.
The installation then proceeded in several steps:
- Validation of the outdoor location to preserve access, ventilation, and maintenance.
- Tracing the duct path on the brick and foundation.
- Installation of the line cover with a clean transition between surfaces.
- Connection of the GREE VITA R32 outdoor unit with proper line insulation.
- Vacuuming and technical checks before startup.
- Operation test in cooling and heating according to available conditions.
- Explanations given to the customer for use, filters, maintenance, and winter instructions.
This process reduces the risks of leaks, vibration, poor drainage, or disappointing performance. It also ensures that the customer understands how to use their device, rather than just receiving a remote control without explanation.
Mistakes to avoid in a similar setup
This project in Deux-Montagnes highlights several common mistakes when installing a wall-mounted heat pump near an entrance or under an outdoor structure.
Installing the unit too close to a door
An outdoor unit must not prevent a door from opening or make a passage less safe. Here, the door remains accessible, and the unit is placed so as not to become a daily obstacle.
Neglecting fan clearance
The front fan must exhaust air freely. A hedge, a wall, an outdoor piece of furniture, or snow accumulation can reduce system efficiency. Even in a tight space, clearance must be respected.
Leaving lines exposed
Poorly protected refrigerant lines age worse and give a messy finish. The line cover protects the system and improves the appearance of the facade.
Ignoring defrost water
In heating, defrost water must be anticipated. Near a basement door, ice accumulation can become problematic. We integrate this reality from the choice of location.
Choosing capacity based only on area
The area gives a first reference point, but it is not enough. A poorly insulated room, very glazed or exposed to the sun may require a more detailed analysis. Conversely, a device that is too large can create short cycles and less stable comfort.
A discreet result for a North Shore house
The client wanted an efficient solution without turning the exterior of the house into a too visible mechanical zone. The result respects this request: the outdoor unit is accessible, the line cover is organized, and the whole remains consistent with the existing structure.
In this type of project, the most satisfying feedback is often very simple: the device works well, the space remains practical, and the installation does not feel hastily added. This is exactly what we look for in our residential HVAC projects.
Useful expertise throughout Greater Montreal
We face similar challenges in several sectors. In Montreal, backyards are sometimes narrow and brick walls require a clean finish. In Laval, some houses have extensions or finished basements that require a well-targeted system. In Longueuil, duplexes and townhouses often require more delicate line routing. On the North Shore and the South Shore, winter constraints, snow accumulation, and outdoor access must always be taken seriously.
This installation in Deux-Montagnes represents our approach well: we don’t just install a machine. We assess the building, the client’s habits, visible obstacles, technical requirements, and long-term maintenance needs.
Practical advice after installing a GREE VITA R32
To maintain good performance, we recommend the client regularly clean the indoor unit filters, especially during periods of intensive use. Outside, keep the grille clear, remove leaves, and clear snow around the unit. No objects should be stored in front of the fan.
We also advise using the heat pump steadily. In summer, a constant temperature helps the system better manage humidity. In heating mode, allowing the unit to modulate gradually often provides better comfort than frequent stops and restarts.
Periodic HVAC maintenance allows checking the coils, drains, connections, overall operating level, and the condition of the outdoor unit. For an installation placed near a passage like this one, maintenance is also an opportunity to confirm that the environment around the machine remains clear and safe.

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.
