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 wall-mounted heat pump precisely installed on an accent wall in Sainte-Rose
In Sainte-Rose, in northern Laval, our AirGreen team carried out the installation of a wall-mounted heat pump GREE LIVO R32, a mini split system designed to provide effective comfort in both cooling and heating modes. This installation stands out immediately by its location: the indoor unit was placed on an orange accent wall, near the ceiling, in a room under development where the visual finish had to remain clean despite technical constraints.
The image shows a white GREE unit, well centered on the wall, installed at a strategic height to free up floor space and promote good air distribution. The contrast between the white casing of the wall-mounted heat pump and the bright color of the wall made alignment particularly important. On a colored surface, even the slightest misalignment becomes much more visible. That is why our team took the time to validate the height, level, position relative to the ceiling, and distance from adjacent walls before finalizing the installation.
In a project like this, the challenge is not only to mount the device. It is also necessary to understand how the air will circulate in the room, how the unit can be maintained, how the refrigerant lines will be routed, and how the installation will fit into the existing space without creating too heavy a visual impact.
Why the GREE LIVO R32 model was well suited for this room
The GREE LIVO R32 is a wall-mounted solution appreciated for residential installations where the client seeks a reliable, compact, and easy-to-use device. In this residence in Sainte-Rose, the choice of this system met several needs: improving the comfort of a main room, reducing heat in summer, providing supplemental heating during cooler periods, and avoiding portable devices or window air conditioners that clutter the space.
The refrigerant R32 is one of the important elements of this range. It is used in several recent wall air conditioner and mini split heat pump systems to meet current efficiency and environmental responsibility requirements. For an owner in Laval, this means more modern equipment, better suited to current HVAC market expectations.
The practical advantages of this installation include:
- a compact wall unit that takes up no floor space;
- an efficient air conditioning mode for hot days;
- a heating mode useful during intermediate seasons;
- adjustable air distribution thanks to adjustable louvers;
- a sober appearance that contrasts neatly with the colored wall;
- simple daily use;
- a solution adapted to houses, condos, and apartments in Laval.
The exact BTU capacity always depends on the installed combination and the building configuration. At AirGreen, we avoid recommending capacity based solely on surface area. We also analyze ceiling height, insulation, solar orientation, openings, heat loss, and usage habits. This analysis allows us to choose a heat pump capable of operating efficiently without too short cycles or excessive strain.
An accent wall that required a flawless finish
Installing a white unit on an orange wall creates a strong contrast. This results in an interesting visual effect when the work is clean, but it also leaves little room for error. The lines must be straight, the drillings must be precise, and the wall plate must be perfectly fixed.
In this installation in Sainte-Rose, our team paid special attention to aligning the indoor unit with the ceiling. The top of the device is close to the ceiling line, which requires careful installation. A slightly tilted unit would have been immediately noticeable. The goal was to maintain a clean appearance while respecting the clearances necessary for the proper functioning of the device.
We also took into account the presence of furniture under the unit and the future use of the room. A successful HVAC installation must remain practical after the technicians leave. It must be possible to access the filters, clean the unit, adjust the louvers, and enjoy comfort without the airflow being blocked by furniture, a curtain, or a decorative element.
A high installation for better air diffusion
High placement is common for a wall-mounted heat pump, but it should never be improvised. Warm air tends to rise, while cold air descends. The unit's positioning must therefore take this natural movement into account to achieve a more stable temperature in the room.
In this project, the GREE unit was installed to diffuse air toward the living space rather than directly toward an obstacle. This decision helps reduce uncomfortable zones and improve the distribution of cooling or heating. The adjustable louvers of the GREE LIVO R32 then allow adjusting the blowing direction according to the season.
In cooling mode, the air can be directed to gradually cool the room without creating a too intense direct draft. In heating mode, adjusting the louvers helps push the air downward to better distribute the heat. These details seem simple, but they greatly change the customer's daily experience.
The technical steps behind a clean installation
The photo shows the final result, but a large part of the work lies in the invisible steps. Before commissioning, a mini split heat pump requires a series of essential checks.
Our team notably validated:
- the strength of the wall and the support;
- the level of the mounting plate;
- the location of the drilling;
- the passage of refrigerant lines;
- the condensation drainage;
- the tightness of the fittings;
- the vacuuming of the circuit;
- the compliant electrical connection;
- the operation of basic modes;
- air diffusion after startup.
These steps are fundamental. An indoor unit may seem well installed, but if the drain is poorly sloped, if the fittings are poorly tightened, if the vacuuming is neglected, or if the unit is not stable, the client may encounter problems later. At AirGreen, we give as much importance to what is seen as to what is unseen.
Practical lessons from this HVAC installation in Laval
Drainage: an essential point to protect the interior wall
In cooling and dehumidification mode, a wall heat pump produces condensation. This water must be properly drained. On a colored wall like this one, a leak or internal flow could quickly leave visible marks. Drainage was therefore a priority point.
A poorly installed drain can cause several problems:
- water leakage under the unit;
- marks on the wall;
- humidity odors;
- noise in the drain;
- water accumulation in the tray;
- avoidable service calls;
- discomfort for the client.
Our team therefore checked the slope and drainage before finalizing the startup. This type of check is part of a true professional wall air conditioner installation.
The choice of location: a decision that influences the following years
The indoor unit was placed in the upper part of the wall, which allows keeping the floor space usable. This decision is particularly important in rooms where the layout may change. The client will be able to move or replace the furniture under the unit without compromising the system's operation, provided that clear air circulation is maintained.
A good location must meet several criteria:
- promote air diffusion;
- remain accessible for maintenance;
- limit visual impact;
- respect the manufacturer's clearances;
- allow reliable drainage;
- facilitate the passage of pipes;
- avoid direct blowing on occupants;
- take into account current and future furniture.
In several houses in Sainte-Rose, the rooms have been renovated over time. The walls, ceilings, windows, and interior fittings do not always follow a standard logic. That is why an evaluation visit is essential before recommending a final location.
Subsidies and eligibility: a check to do with the exact model
Owners in Montreal, Laval, Longueuil, the North Shore, and the South Shore often ask if their wall-mounted heat pump is eligible for a subsidy. Programs like Hydro-Québec's LogisVert can reduce the final cost of a project, but eligibility depends on the exact installed combination, certified performance, and criteria in effect at the time of application.
For a GREE LIVO R32, always verify the indoor and outdoor model numbers, BTU capacity, applicable efficiencies, and official documentation. AirGreen assists customers in this verification to provide clear information and avoid unpleasant surprises.
The price of an installation should never be evaluated solely based on the amount shown on the quote. You should also consider:
- installation quality;
- drainage reliability;
- compliance with standards;
- the warranty;
- energy efficiency;
- potential eligibility for subsidies;
- after-sales service;
- the availability of parts;
- the reputation of the installer.
Mistakes to avoid with a GREE LIVO R32 wall-mounted heat pump
An installation like this may seem simple once completed, but several mistakes can reduce system performance.
Installing the device too close to the ceiling without checking the air return
The proximity to the ceiling must be carefully evaluated. Insufficient clearance can hinder air circulation and make the device less efficient.
Neglecting furniture under the unit
A piece of furniture that is too tall or too close can hinder air distribution. It can also complicate access to the filters.
Choosing a BTU capacity without a complete analysis
Surface area alone is not enough. A sunny room, poorly insulated or open to another space, can have very different needs.
Forgetting filter maintenance
A dirty filter reduces air circulation, increases system effort, and decreases comfort. Regular HVAC maintenance helps preserve performance.
Entrusting the installation to an unqualified person
Handling refrigerants, refrigeration connections, and commissioning must be carried out by qualified professionals. Poor installation can negate the benefits of a good device.
Usage tips to maximize comfort
After starting this GREE LIVO R32 wall-mounted heat pump, we explained to the client the best usage practices. To achieve stable comfort, it is better to maintain a reasonable temperature rather than constantly turning the unit off and on. In cooling mode, this also helps better control humidity.
The louvers should be adjusted according to the season. In summer, indirect diffusion helps cool the room without creating unpleasant drafts. When heating, it is better to direct the air to better distribute warmth in the occupied area.
Filters must be cleaned regularly, especially in an active room or during renovation periods. Dust can quickly accumulate on surfaces and inside the unit. Simple cleaning, done at the right time, helps maintain good airflow.
