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.
A sober and efficient indoor installation in a room with very clean lines
In Vimont, in the northern sector of Laval, our AirGreen team carried out the installation of a wall-mounted heat pump GREE LIVO R32, also used as a mini split wall air conditioner, in a room where visual integration was an important criterion. The project photo shows an indoor unit placed high on a white wall, near the ceiling, in a very sober environment. Here, no decorative detail could hide a rough installation: alignment, height, finish, and the discretion of the connections had to be impeccable.
This type of HVAC installation seems simple when looking only at the final result. However, a wall unit installed too close to the ceiling, poorly leveled, or poorly oriented can quickly create problems with comfort, noise, maintenance, or drainage. In this Vimont house, our job was to find the right balance between aesthetics, performance, and future accessibility.
The GREE LIVO R32 is well suited for this type of residential project. It combines the functions of a heat pump and a wall air conditioner, with a compact format and a discreet appearance. The manufacturer states that the LIVO R32 series can reach up to 20.5 SEER2, 12.5 EER2, and 8.8 HSPF2, depending on the exact combination of units, with a heating range announced down to -13 °F, or about -25 °C.
A high installation that requires more than just a good level
In the photo, the indoor unit is installed near the ceiling, on a clear wall. This choice allows for good air distribution in the room, but it also requires several technical checks. A wall-mounted heat pump must have enough space to draw air from the top, allow the panel to open, provide access to the filters, and maintain a proper slope for the condensate drain.
Before the final attachment, our team therefore validated:
- the necessary clearance above for proper operation;
- the ideal location to avoid uncomfortable direct airflow;
- the solidity of the wall surface;
- the exact level of the mounting plate;
- the routing of refrigerant lines;
- the drain slope;
- future access for HVAC maintenance;
- the visual alignment relative to the ceiling and adjacent wall.
In a white and minimalist room, the slightest mistake is immediately noticeable. A slightly tilted unit, a poorly positioned duct outlet, or a miscalculated space can give the impression of sloppy work, even if the unit works. At AirGreen, we give as much importance to this finishing as to mechanical performance because a wall air conditioner installation is part of the client’s daily decor.
The detail visible in the photo: a well-integrated unit, without visual overload
The GREE indoor unit appears neatly installed, with a very light visual presence. The digital display is visible on the front, the louvers are open, and the unit blends into the white wall. In this type of space, the client didn’t just want an air conditioning solution; they wanted an installation that respects the room’s appearance.
We therefore favored a very clear approach: high positioning, straight installation line, unit centered according to the room’s logic, and discreet finishing around the unit. This kind of work is common in Laval, especially in renovated houses or condos where owners want to improve comfort without changing the interior ambiance.
The GREE LIVO R32 is particularly interesting for this type of installation because its design is simple and its white front easily fits into many residential decors. It is well suited for rooms where the owner wants an efficient solution without giving the equipment too much presence.
Why the indoor position directly affects comfort
A mini wall split is not limited to cooling or heating a room. It must distribute air intelligently. A poorly placed unit can blow air directly onto a bed, a sofa, a desk, or a passage area. It can also create temperature differences if the air does not circulate properly.
In this installation in Vimont, the mounting height allows the treated air to spread throughout the room before naturally descending. In cooling mode, this helps achieve a more uniform sensation, without harsh drafts. In heating mode, the orientation of the louvers and ventilation settings become essential to push warm air toward the occupied area.
Our team took the time to explain to the customer how to use the ventilation modes, the orientation of the louvers, and the temperature settings. A good machine delivers better results when well understood. Many owners set their heat pump like an old window air conditioner, with too large temperature differences. We recommend stable settings, regular use, and filter maintenance to preserve efficiency.
The GREE LIVO R32: performance, R-32 refrigerant, and inverter technology
The GREE LIVO R32 uses an R-32 refrigerant, combined with inverter technology. This combination allows the device to adjust its operation according to the actual needs of the room, instead of operating only in abrupt on/off cycles. For the customer, this generally means more stable comfort, less marked temperature variations, and smoother operation.
The LIVO R32 series is designed for single-zone residential applications. GREE also mentions a maximum line length of up to 131 feet, depending on the series' installation limits, which can offer good flexibility when the ideal indoor location is not directly behind the outdoor location.
In an area like Vimont, where houses can have different configurations — bungalows, multi-story houses, condos, renovated homes, extensions — this flexibility is useful. The best indoor location is not always the easiest for running the lines. Our role is therefore to evaluate the best technical route, without compromising the interior appearance or the device's performance.
Capacity in BTU: a decision that must be calculated, not guessed
For this installation, the capacity selection was made according to the actual needs of the room and the building configuration. Even when the commercial model is the same, the GREE LIVO R32 can exist in different capacities. The right choice depends on several factors:
- area of the room or zone to be treated;
- ceiling height;
- insulation quality;
- sun exposure;
- number and size of windows;
- room usage;
- presence of other heat sources;
- air circulation to neighboring rooms.
A device that is too small may run too long without reaching the desired comfort. A device that is too large may quickly reach the requested temperature, but with shorter cycles and less effective dehumidification in summer. This is a common mistake when customers only compare price or choose a capacity “by feel.”
At AirGreen, we prefer to analyze the room and recommend the appropriate configuration. This is especially important for wall-mounted heat pump projects in Montreal, Laval, Longueuil, on the North Shore and on the South Shore, where buildings have very different profiles.
Practical lessons from this installation in Vimont
A successful wall installation starts with the invisible details
The final result is visible: a clean, straight, and well-integrated unit. But much of the work lies behind this simple appearance. Refrigerant connections must be made precisely, pipe insulation must be well done, the drain must be reliable, and communication between units must be verified.
A quality HVAC installation also relies on commissioning. Once the unit is installed, our team checks the operation in cooling and heating, the remote control response, the opening of the vents, drainage, operating noise, and the absence of abnormal vibration. We never consider a device ready just because it turns on.
In this project in Vimont, the device is installed in a very visible area. This requires a clean execution, but also careful commissioning. A well-adjusted system from the start limits unnecessary service calls and gives the customer a better experience from the first hours of use.
HVAC maintenance: the simple action that protects performance
A GREE LIVO R32 wall-mounted heat pump must be maintained regularly. For the customer, the first step is to clean the filters of the indoor unit. Clogged filters reduce airflow, increase the effort of the device, and can affect comfort. Depending on usage, monthly or seasonal cleaning may be necessary.
Professional maintenance goes further. It can include cleaning the exchanger, turbine, drain, outdoor unit, as well as checking overall performance. In Laval homes, outdoor units are exposed to leaves, dust, pollen, snow, and freeze-thaw cycles. A clean system works better and lasts longer.
We often remind clients that a wall air conditioner used only in summer still deserves periodic checks. For a heat pump also used for heating, maintenance becomes even more important because the device works for a larger part of the year.
Subsidies: verify the exact combination, not just the brand
Clients installing a heat pump in Laval often want to know if their system qualifies for financial aid. Hydro-Québec’s LogisVert program offers a search tool to evaluate financial aid based on the heat pump’s model number or AHRI number.
To avoid misunderstandings, always verify the exact installed combination: indoor unit, outdoor unit, AHRI number when applicable, and recognized performance. The name “GREE LIVO R32” alone is not enough to confirm an amount. Two combinations from the same product family can have different efficiencies.
At AirGreen, we help clients gather the necessary information: detailed invoice, model numbers, proof of installation, and available technical data. This thoroughness makes the process easier and helps the client better understand what is actually eligible.
Mistakes to avoid in a room like this
This installation in Vimont highlights several common mistakes we see in wall-mounted mini split projects.
The first mistake is placing the unit too close to the ceiling without checking the suction clearance. Even if the device seems more discreet, it must be able to breathe properly.
The second mistake is neglecting the drain. A poor slope can cause water drainage issues, especially in cooling mode when humidity is high.
The third mistake is choosing the location based only on appearance. The unit should look good, but it must also distribute air properly, be accessible, and allow for easy maintenance.
The fourth mistake is ignoring potential noise. A poorly fixed or uneven installation can cause vibrations. The quality of the installation directly affects sound comfort.
The fifth mistake is underestimating the importance of after-installation service. A good contractor doesn’t disappear after startup. They explain how to use the system, answer questions, and remain available for maintenance.
AirGreen in Laval: expertise adapted to the realities of Vimont homes
AirGreen regularly works in Laval, especially in Vimont, Duvernay, Chomedey, Sainte-Dorothée, Pont-Viau, Fabreville, Laval-des-Rapides, and Sainte-Rose. Each neighborhood has its own particularities: older houses, recent renovations, narrow walls, complex exterior access, condos with co-ownership rules, or rooms difficult to air condition.
Our approach remains the same: to offer an HVAC solution adapted to the actual building. We don’t just aim to install a machine. We aim to create a coherent system, well installed, easy to use, and durable.
This installation of a GREE LIVO R32 in Vimont clearly illustrates our method. The indoor unit is discreet, well positioned, and suited to a simple, bright, and uncluttered room. The client gets a wall-mounted heat pump solution capable of improving daily comfort without weighing down the appearance of their space.
A clean, stable final result designed for daily use
The final result is a GREE LIVO R32 wall-mounted heat pump installed high on a white wall, with a simple finish and natural integration into the room. The unit offers the client a two-in-one solution: air conditioning during hot periods and heating according to seasonal needs.
For homeowners in Vimont and Laval considering a HVAC installation, this project highlights an important reality: the quality of a heat pump depends as much on the product as on how it is installed. A good machine poorly placed can disappoint. A well-selected, well-installed, and well-explained machine becomes a true comfort tool.
At AirGreen, we put this precision at the heart of every project, whether in Montreal, Laval, Longueuil, on the North Shore or on the South Shore. This installation in Vimont is a concrete example: a clean, efficient, discreet solution designed to last.

And at your place?
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.
