An indoor installation in Montreal where the finish mattered as much as the performance
In Montreal, our AirGreen team carried out the installation of a wall-mounted heat pump GREE LIVO R32, a mini split system designed to offer both air conditioning, efficient supplementary heating, and precise indoor comfort control. The photo clearly illustrates one of the most important elements of this project: the indoor wall unit was installed in a finished room, on a light wall, near the ceiling, with a clean and discreet visual integration.
In this type of Montreal residence, the challenge is never just to install a functional machine. It is necessary to respect the appearance of the room, choose an appropriate height, ensure good air diffusion, avoid unnecessary marks on the walls, and precisely coordinate the passage of ducts to the outside. A successful HVAC installation must visually go unnoticed while clearly improving daily comfort.
Here, the GREE LIVO R32 was positioned on a clear wall, at a height that promotes effective air distribution. The indoor unit is centered in an area allowing the airflow to circulate freely into the room, without being blocked by furniture, a decorative beam, a curtain, or a nearby partition. The presence of a textured wall or a brick element on the left side of the photo also shows that the space had a certain architectural identity. Our job was therefore to integrate the system without harming the interior character of the room.
Why the GREE LIVO R32 was suitable for this residential project
The GREE LIVO R32 is a wall-mounted heat pump of the mini split type, a solution particularly suited for apartments, condos, duplexes, triplexes, and townhouses in Montreal. It meets the needs of homeowners who want to add efficient air conditioning without installing a full duct network, while benefiting from supplementary heating during cooler periods.
This model uses the refrigerant R32, increasingly present in modern residential HVAC systems. R32 allows good thermal transfer and is part of a new generation of equipment more efficient than many older platforms using other refrigerants. Combined with inverter technology, it allows the unit to modulate its operation according to the actual demand of the room.
For the client, this means more stable comfort. Instead of operating only on an on-off basis, the heat pump adjusts its speed to maintain a steady temperature. This modulation reduces sudden variations, improves the comfort feeling, and can contribute to better-controlled energy consumption when the unit is properly sized.
The BTU capacity must always be confirmed according to the exact configuration of the dwelling. At AirGreen, we evaluate several factors before validating the capacity of a wall air conditioner: area, ceiling height, insulation, solar orientation, number of windows, building airtightness, room usage, and air circulation between zones. In a Montreal dwelling, these details vary greatly from one property to another, especially between a recent condo, an old ground floor, a top floor very exposed to the sun, or a unit with shared walls.
An indoor positioning designed for air circulation
The indoor unit visible in the photo is installed near the ceiling, on a clear wall. This choice is important for a wall-mounted heat pump, as the air must be blown into the room without immediate obstacles. An installation that is too low or too close to a corner can reduce distribution efficiency. An installation too close to the ceiling, without sufficient clearance, can also hinder air intake from the top of the unit.
In this project in Montreal, the goal was to find the right balance: an aesthetic height, good diffusion capacity, reasonable access for filter maintenance, and a clean integration into the room. The unit is placed to remain discreet while being effective. Its white color blends well with the light decor, avoiding the effect of an overly imposing installation.
This attention to location is often what distinguishes an ordinary installation from a true professional HVAC installation. A wall unit must be installed to operate properly for years, not just to look good on installation day.
The challenge of finished walls in Montreal homes
Installing a GREE LIVO R32 wall heat pump in an already finished space requires precision. Interior walls may hide studs, electrical wires, pipes, old repairs, or more fragile materials. In some homes in Montreal, there are also uneven walls, decorative finishes, lower ceilings, or access constraints to the outside.
Our team therefore worked with a rigorous method:
- checking the drilling area;
- exact positioning of the wall plate;
- leveling the indoor unit;
- planning the routing of refrigerant lines;
- care taken with the condensation drain;
- clean sealing of the wall passage;
- protection of the interior finish.
The condensation drain is a critical point. In cooling mode, the indoor unit removes moisture from the air. This water must be properly drained, with an adequate slope or with a mechanical solution when the setup requires it. Poor drainage can cause leaks, stains on the wall, odors, or damage to the building. In a finished interior like this, there is no room for approximation.
A discreet finish to preserve the appearance of the room
In the photo, the installation looks visually simple: a white wall unit, a light wall, no visible piping in the room, a clean line under the ceiling. This is exactly the type of finish sought by many homeowners in Montreal, Laval, Longueuil, on the North Shore and on the South Shore.
In many projects, clients ask if a heat pump will harm the appearance of their living room, office, bedroom, or open area. The answer largely depends on the choice of location and the quality of the installation. A well-placed unit can become very discreet. A poorly positioned unit, on the other hand, can unnecessarily draw attention or complicate the room layout.
At AirGreen, we consider the actual use of the space. In this installation, it was necessary to maintain a simple indoor atmosphere, avoid visual clutter, and ensure good accessibility to the filters. The unit can be opened and maintained without moving large furniture or working in an uncomfortable position.
Technical choices that make this GREE LIVO R32 installation durable and efficient
A wall-mounted heat pump only delivers its full performance if the installation follows best practices. The machine matters, but the work around the machine matters just as much: refrigerant connections, vacuuming, drainage, sealing, line protection, electrical supply, outdoor location, and commissioning.
Concrete advantages for the client
In this Montreal project, the GREE LIVO R32 improves comfort in a specific area without heavy construction. The client benefits from a compact wall unit capable of cooling the room during hot and humid summer days in Montreal, while also providing supplementary heating during transition periods.
The main benefits are clear:
- more stable air conditioning during heat periods;
- better indoor humidity management;
- useful supplementary heating in spring, fall, and depending on winter conditions;
- modulating operation thanks to inverter technology;
- installation without ductwork;
- discreet format suitable for urban housing;
- local temperature control in the served area.
For properties in Montreal, this flexibility is particularly useful. Buildings can have rooms that overheat in summer, poorly ventilated bedrooms, sun-exposed living rooms, or floors where air does not circulate well. A mini split solution allows you to precisely target these problems without overhauling the entire home's mechanical system.
Mistakes to avoid during an indoor installation
Installing a wall air conditioner seems simple when only looking at the indoor unit, but many mistakes can compromise the result.
Installing the unit in the wrong place
A poorly chosen location can create areas that are too cold, direct drafts on occupants, or poor air circulation. The unit should not blow directly on a bed, sofa, or workspace used for long periods.
Neglecting drainage
An insufficient slope or poorly positioned drain can cause water problems. In a finished room, this can quickly become costly. Drainage must be planned from the start, not fixed afterward.
Choosing capacity based only on surface area
Two rooms of the same size can have very different needs. An open area with large south-facing windows does not require the same capacity as an interior room with little sun exposure. The BTU capacity must be chosen carefully.
Installing without considering maintenance
The indoor unit filters must be accessible. A device installed too high, too close to a shelf, or above an obstacle can discourage regular maintenance. Good HVAC maintenance starts with easy access.
Drilling without wall analysis
In a Montreal building, walls can hold surprises. A careful inspection reduces the risk of damage and allows for a cleaner installation.
Subsidies and eligibility: an essential check before the file
For owners in Montreal, subsidy programs can make installing a heat pump more advantageous. Eligibility, however, depends on the exact model, installed capacity, current technical criteria, and administrative requirements of the program applicable at the time of the work.
For a GREE LIVO R32, we always recommend verifying the exact model information before submitting a file. At AirGreen, we help our clients gather the necessary information, such as the brand, model, detailed invoice, and required technical data. This step avoids unpleasant surprises and helps the client better understand the conditions related to subsidies.
The AirGreen experience in wall-mounted installations in Montreal
We regularly install wall heat pumps, wall air conditioners, and mini split systems in homes in Montréal, but also in Laval, Longueuil, on the North Shore, and on the South Shore. Each area has its particularities. In Montréal, the most common constraints involve exterior access, party walls, condominiums, balconies, alleys, narrow yards, old walls, and aesthetic requirements.
In this project, the simplicity of the interior installation was a central element. The photo shows a clean result, with no visible ductwork in the room, and a well-aligned and well-integrated unit. For a client, this level of finishing greatly changes the perception of the project. A heat pump must improve comfort, but it must also respect the living space.
A result that combines comfort, discretion, and technical rigor
This installation of a GREE LIVO R32 wall heat pump in Montréal shows that a good HVAC project relies on a series of precise decisions. The choice of model, mounting height, airflow direction, drilling, drainage, interior finishing, and commissioning must be consistent from start to finish.
The final result is a discreet, efficient solution adapted to a Montréal residential interior. The wall unit integrates neatly into the decor, the system provides a concrete response to air conditioning and supplementary heating needs, and the installation meets the necessary standards to ensure good durability.
At AirGreen, we approach every project with the same high standards: offering a solution tailored to the building, carefully installed, designed for the real comfort of the client, and supported by local expertise in HVAC. Whether in Montréal, Laval, Longueuil, on the North Shore or on the South Shore, our goal remains the same: to deliver a clean, reliable, and well-thought-out installation, capable of serving the client season after season.
The job tools
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Baseboards and electric furnaces turn 1 kWh of electricity into 1 kWh of heat. A heat pump delivers more: that is its COP. At Hydro-Québec’s rate D (11.142¢/kWh above 40 kWh a day, since 1 April 2026):
Hydro-Québec: a heat pump can be up to three times more efficient than baseboards for heating in the colder months.
Estimate per kWh of heat, at the chosen temperature, using the certified COP from the product page. Taxes, access charge and backup heat not included.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.

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.
