A compact and strategic installation in an open space between the kitchen and living area
In Pont-Viau, a well-established residential area of Laval, our AirGreen team carried out the installation of a GREE LIVO R32 wall-mounted heat pump, a mini split wall air conditioner system designed to improve comfort in an indoor area where air circulation had to be carefully planned. The unit was installed high on a light textured wall, immediately near an opening to the kitchen, under a dropped ceiling, and close to dark wood cabinets visible in the adjacent room.
This type of configuration is common in houses and condos in Laval, especially in neighborhoods like Pont-Viau, where rooms have often been renovated over the years: decorative walls, enlarged openings, dropped ceilings, semi-open kitchens, shared living areas. For a quality HVAC installation, it is not enough to choose a high-performance device. You also need to understand how air moves in the actual space, how occupants use the room, and how to integrate the unit without compromising the interior aesthetics.
In this project, the goal was clear: to install a discreet, efficient, and well-oriented wall-mounted heat pump, while respecting the physical limits of the wall and the proximity of the ceiling. The result is a compact, clean installation well integrated into an environment where every available inch mattered.
A location chosen to maximize air diffusion
The GREE indoor unit was installed above a decorative wall with horizontal panels, in an area that allows the treated air to diffuse toward the main space and the adjoining kitchen. The presence of an opening on the right side made this choice particularly interesting: instead of concentrating comfort in a single closed room, the device can help stabilize the temperature in a larger living area.
The height positioning also helps avoid obstacles such as furniture, cabinets, countertops, or appliances. In a kitchen or transition area, this decision is important because a unit installed too low or poorly oriented can blow directly on the occupants, create a feeling of discomfort, or be exposed to localized heat sources.
At AirGreen, we always evaluate several factors before fixing the final location of a wall air conditioner:
- the distance between the top of the unit and the ceiling;
- the presence of a soffit or bulkhead;
- the natural direction of air circulation;
- proximity to the kitchen and heat sources;
- the position of cabinets, doors, and openings;
- possible routing of refrigerant lines;
- condensate drain management;
- future access for HVAC maintenance.
In this installation in Pont-Viau, the space above the textured wall offered a solution that was both practical and aesthetic. The unit remains visible but does not dominate the room. Its white color blends with the light wall, giving a sober and professional impression.
Why the GREE LIVO R32 was a good choice for this project
The GREE LIVO R32 is a wall solution appreciated for residential installations where a good balance between comfort, efficiency, discreet size, and reasonable cost is sought. It is particularly suitable for living spaces, condos, open kitchens, living rooms, and mixed areas where occupants want to improve cooling in summer while benefiting from effective supplementary heating during cooler seasons.
The model uses the refrigerant R32, a next-generation refrigerant increasingly found in modern wall systems. This choice aligns with the evolution of HVAC equipment towards more efficient solutions better suited to current standards. For a Pont-Viau homeowner, this means a contemporary device, well suited for residential installation and compatible with current performance expectations.
Depending on the chosen capacity and the exact combination of indoor and outdoor units, the LIVO R32 range can offer interesting performance in cooling and heating. However, data such as the SEER2, HSPF2, BTU capacity, and subsidy eligibility must be validated with the exact model number, the installed combination, and the corresponding AHRI number. At AirGreen, this verification is part of our submission process, as two devices that look similar can have different results depending on their configuration.
A delicate installation near a ceiling drop
The project photo shows an important detail: the unit is installed very close to a ceiling drop. This constraint requires great precision. A wall-mounted heat pump needs sufficient clearance to properly draw air from above and ensure good circulation. If the device is too close to the ceiling, its performance may be affected and access to the filters may become more difficult.
Our team therefore paid special attention to the installation height, tilt, alignment, and stability of the wall support. In a professional installation, the device must be securely fixed, perfectly level, and placed to allow the front panel to open for regular maintenance.
This type of detail makes a big difference in the long run. A quick but poorly adjusted installation may seem acceptable at first but cause problems later: noise, vibration, difficult access to filters, poor air intake, imperfect drainage, or discomfort in the room. In Pont-Viau, we favored a clean, measured approach adapted to the available space.
The challenge of the decorative wall: secure attachment without compromising the finish
The wall on which the unit was installed has a decorative finish with rectangular panels. This type of surface requires a different approach than a standard flat wall. You must consider the reliefs, joints, coating stability, and the best way to achieve a solid attachment without unnecessarily damaging the interior finish.
For a mini split installation, the wall plate must be perfectly stable. The indoor unit rests on this support, and the pipes must be properly aligned behind or near the device. A rough attachment can cause a slight visible misalignment, especially on a decorative wall where horizontal and vertical lines make any error more apparent.
Our team therefore worked precisely to ensure that the GREE unit was well positioned relative to the wall lines. This visual care is important, but it also reflects technical rigor: a straight, well-supported, and neatly installed device inspires confidence and facilitates future interventions.
The proximity of the kitchen: a factor not to be overlooked
Installing a wall-mounted heat pump near a kitchen requires special attention. The kitchen produces heat, humidity, sometimes vapors, and rapid temperature changes. The choice of location must avoid the device being directly exposed to cooking sources or drawing in too much particle-laden air.
In this project, the unit was placed on an adjacent wall rather than above the cooking area. This decision helps preserve the device's operation and maintain better air quality. It also helps distribute comfort to the living area without creating too direct an airflow over the counter or cabinets.
For homeowners considering a HVAC installation in Laval, this nuance is important. A device may be technically capable of cooling a space, but its location will largely determine the actual comfort. A good installation takes into account how the house is used every day.
Condensation management: a key point for wall installations
In cooling mode, the indoor unit extracts moisture from the air and produces condensation. This water must be reliably drained. In a high installation, near a ceiling drop and an adjacent room, the drain path must be planned before the final installation.
A bad slope or poorly executed passage can cause problems: drips on the wall, infiltration, odors, water accumulation, or avoidable service calls. At AirGreen, we treat drainage as a central part of the installation, not just a minor detail.
In this installation in Pont-Viau, planning allowed respecting the wall configuration and preserving the interior finish. This is exactly what our clients are looking for: an effective heat pump, but also an installation that remains clean and reliable after the technicians leave.
Common mistakes to avoid in a similar installation
A compact wall installation like this may seem simple, but several mistakes are common when the work is not well planned.
Installing the unit too close to the ceiling
Insufficient clearance can hinder air intake and make maintenance more difficult. The available space must always be measured before confirming the location.
Ignoring the lines of the decorative wall
On a textured or decorative wall, a slightly crooked device becomes very noticeable. The alignment must be precise.
Placing the unit too close to a heat source
In a kitchen, the device should not be directly exposed to the cooking area. This can affect temperature readings and increase filter clogging.
Choosing capacity based only on surface area
The number of BTUs must be determined based on the area, but also on insulation, sun exposure, openings between rooms, ceiling height, and occupant habits.
Neglecting access for maintenance
A device installed in a space that is too tight can become difficult to clean. Filters must remain accessible to ensure good performance.
AirGreen expertise tailored to homes and condos in Pont-Viau
AirGreen regularly works in Laval, both in residential neighborhoods like Pont-Viau, Laval-des-Rapides, Chomedey, and Duvernay as well as in the North Shore, Montreal, Longueuil, and South Shore areas. This experience allows us to quickly recognize the typical constraints of buildings in the region: renovated walls, semi-open rooms, low ceilings, limited outdoor access, condominiums, semi-detached houses, and installations where interior aesthetics are as important as performance.
A complete installation process
For this project, our work was not limited to installing the wall unit. A professional installation includes several essential steps:
- validation of the indoor location;
- confirmation of the technical route;
- secure mounting of the wall plate;
- routing of refrigerant lines and drain;
- connection to the outdoor unit;
- vacuuming the lines;
- checking for leaks;
- testing in cooling and heating modes;
- explanation of operation to the client;
- maintenance recommendations.
This method delivers a reliable, efficient installation tailored to the actual use of the home.
Comfort achieved after installation
Once the GREE LIVO R32 is running, the goal is to create a more stable temperature in the served area. Thanks to its modulating operation, the device can adjust its output according to demand, rather than operating only in abrupt cycles. This modulation helps reduce temperature fluctuations and improve daily comfort.
In a space like this, located between a kitchen and a living area, comfort depends greatly on air circulation. The unit must be able to treat the air without creating an unpleasant draft. The choice of location in Pont-Viau precisely followed this logic: to send the air in the right direction while keeping the device discreet and accessible.
Subsidies and eligibility: a necessary verification
Some wall-mounted heat pumps may be eligible for subsidy programs, depending on the exact model, capacity, installed combination, and current criteria. For the GREE LIVO R32, this verification must be done on a case-by-case basis, notably based on the indoor and outdoor model numbers as well as the applicable AHRI number.
At AirGreen, we support our clients in this step to avoid unpleasant surprises. A subsidy should never be assumed based solely on the brand or series name. Technical validation is part of a serious quote, especially for homeowners in Montreal, Laval, Longueuil, the North Shore, and the South Shore who want to plan their budget precisely.
A project that illustrates the value of a well-thought-out installation
This installation in Pont-Viau demonstrates the importance of a professional approach in residential spaces where there are many constraints. The wall unit had to be placed high, on a decorative wall, near a kitchen, with a dropped ceiling and limited workspace. A poor decision could have affected comfort, appearance, or future maintenance.
The final result is a clean, compact, and consistent installation of the GREE LIVO R32 wall-mounted heat pump with the interior design. For homeowners looking for a mini split wall air conditioner in Laval, this project shows that a good device must always be accompanied by a careful installation. The performance of an HVAC system depends as much on the quality of the equipment as on the precision of the work done on site.
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.

What we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.
