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 GREE LIVO R32 wall installation perfectly adapted to a bright residential space in Chomedey
In Chomedey, in a residential area of Laval where houses and condos often have very varied interior layouts, our AirGreen team installed a GREE LIVO R32 wall-mounted heat pump, also used as a mini split wall air conditioner. The project had a simple but very concrete goal: to improve the thermal comfort of a main room without cluttering the space, without encroaching on existing openings, and without creating a visually intrusive installation.
The image of this project clearly shows the spirit of the project: a white GREE indoor unit, installed high on a light wall, near the ceiling, in a sober and bright environment. The presence of a nearby window required special consideration of the airflow direction, shutter orientation, distance from the ceiling, and the overall integration of the device. In a room where natural light enters directly, the wall-mounted heat pump must compensate for heat gains in summer while maintaining comfortable and stable diffusion.
At AirGreen, this type of installation is never treated as a simple mechanical setup. Every HVAC (heating, ventilation, and air conditioning) project must take into account the building’s reality: room dimensions, ceiling height, location of openings, air circulation, occupant habits, maintenance accessibility, and technical constraints related to refrigerant line routing.
Why the GREE LIVO R32 model was a relevant choice for this installation
The GREE LIVO R32 is a wall-mounted solution appreciated for residential projects where a compact, efficient, and easy-to-use device is sought. In this case in Chomedey, the system met several important needs: cooling during hot periods, supporting heating during intermediate seasons, improving humidity control, and offering a more flexible solution than a window unit or a portable system.
The refrigerant R32 also represents an important advantage in recent equipment. It is used in several new generations of wall systems and allows a more current design in terms of energy efficiency and environmental impact compared to some older refrigerants. For owners, this means a modern unit, better suited to current market expectations for the wall-mounted heat pump.
The GREE LIVO R32 series is notably distinguished by:
- a compact and discreet wall-mounted design;
- operation in cooling mode and in heating mode;
- air distribution adjustable by motorized louvers;
- a use adapted to main rooms, bedrooms, condos, and residential spaces;
- a sober appearance, easy to integrate into a light decor;
- a technology designed for simple daily use;
- an interesting solution for owners looking for a good balance between budget, comfort, and reliability.
The exact BTU capacity must always be validated according to the actual project configuration. The same room may require a different capacity depending on its sun exposure, insulation, ceiling height, windows, and its opening to other spaces. In this installation, the chosen location allowed maximizing the efficiency of the mini split while keeping the indoor unit in a logical and discreet place.
A location near the ceiling that required great precision
The indoor unit was installed very high on the wall, near the ceiling. This choice is common for a wall-mounted heat pump, but it must be done carefully. A unit placed too close to the ceiling can hinder air intake and reduce the unit's efficiency. Conversely, a unit placed too low can be less aesthetic, more exposed to impacts, and less effective at distributing air in certain configurations.
In this room in Chomedey, our team made sure to respect the necessary clearances to allow air to circulate properly around the unit. The goal was to achieve a stable, clean, and functional installation while keeping the unit visually aligned with the lines of the wall and ceiling.
Several checks were made before the final fixing:
- Wall strength and quality of support.
- Exact level of the mounting plate.
- Available upper clearance.
- Position of the diffusion louvers.
- Air orientation relative to the window.
- Possible passage for refrigerant lines.
- Condensation drainage.
- Accessibility for filter cleaning.
- Visual aspect from the room entrance.
- No direct obstacle in front of the air outlet.
The photo shows a well-integrated unit, installed in a minimalist space where the finish matters a lot. On a pale wall, the slightest tilt or irregularity becomes visible. That’s why alignment is an essential part of the work.
The importance of airflow in a room with a window
The window visible in the photo brings in natural light, but it can also influence the indoor temperature. In summer, sunlight can quickly increase the perceived heat, especially if the room faces a very exposed area. In winter or cold seasons, proximity to a window can also create a cooler sensation if the insulation or glazing is not optimal.
The GREE LIVO R32 was therefore installed to promote uniform air distribution, without directing the airflow directly toward an uncomfortable area. The unit’s louvers allow adjustment of the direction, but the initial positioning remains crucial. A good HVAC installation always starts with understanding the natural movement of air in the room.
In a home in Laval, particularly in Chomedey where there are many condos, duplexes, semi-detached houses, and compact buildings, this detail can make a big difference. A well-placed system can improve comfort throughout the room. A poorly oriented system can create zones that are too cold, unpleasant drafts, or an uneven temperature sensation.
A clean, simple, and easy-to-maintain installation
One of the great advantages of a mini split wall heat pump is its discretion when properly installed. In this project, the white casing of the GREE LIVO R32 naturally blends into the wall. The result is clean, without visual overload, which suited the space very well.
To ensure this quality of finish, our team paid attention to several details:
- straight and solid mounting of the indoor unit;
- careful drilling for pipe passage;
- surface protection during work;
- checking the condensate drain;
- complete commissioning after installation;
- checking the operation of main modes;
- explanation of controls to the customer;
- filter maintenance advice.
A successful installation is not judged only when the unit starts. It must remain practical for many years. Filters must be accessible, the unit must be easy to clean, the drain must work properly, and the system must be installed to minimize unnecessary interventions.
Technical decisions that ensure performance, durability, and comfort in Laval
Proper sizing: a step never to be overlooked
In wall-mounted heat pump projects in Chomedey, a common mistake is to choose a unit solely based on the room’s area. This method is too simplified. Sizing a wall air conditioner or a mini split must take several factors into account.
A very sunny room may require a different capacity than a room on the shaded side. A higher ceiling increases the air volume to be treated. Poor insulation can cause greater heat loss or heat gain. A room open to a corridor or another area can also change the distribution strategy.
At AirGreen, we evaluate these elements before recommending a model:
- actual area;
- air volume;
- insulation;
- solar orientation;
- number and size of windows;
- type of occupancy;
- number of electrical devices generating heat;
- heating expectations;
- air conditioning expectations;
- desired noise level;
- possibility to install the outdoor unit in a suitable location.
For the GREE LIVO R32, as with any other heat pump, this analysis helps select a capacity consistent with actual use. A unit that is too small risks running continuously on hot days. A unit that is too large can quickly reach the setpoint but manages humidity less effectively and creates short cycles. Comfort comes from balance, not just nominal power.
Vacuum sealing and refrigeration connections: an invisible but essential job
In the photo, you mostly see the indoor unit. Yet, a large part of the quality of an HVAC installation lies in what is not visible: the refrigerant connections, vacuuming, sealing, drainage, and electrical connection.
With a system using R32, installation rigor is essential. The lines must be properly connected, the flares must be well made, the circuit must be vacuumed according to best practices, and the necessary tests must be performed before commissioning. Neglect at this stage can lead to performance loss, leaks, premature wear, or avoidable service calls.
This is one of the reasons why AirGreen never treats the installation of a mini split as just equipment placement. The professionalism of the team is measured by the precision of the technical steps, even those the customer doesn’t see once the work is finished.
Drainage: a detail that prevents many problems
A wall-mounted heat pump produces condensation in cooling and dehumidification modes. This water must drain naturally, without backflow, stagnation, or risk of running down the interior wall. In a high installation like this, the drain must be carefully planned.
Poor drainage can cause:
- water leakage under the unit;
- marks on the wall;
- musty odors;
- gurgling noise;
- water accumulation in the tray;
- unnecessary service calls;
- discomfort for the customer.
During this project in Chomedey, the drain slope and condensation outlet were carefully checked. This kind of detail protects both the building and the reputation of the installed system.
Subsidies and energy efficiency: carefully check the exact model
Customers from Montreal, Laval, Longueuil, the North Shore, and the South Shore often ask questions about the subsidies available for wall-mounted heat pumps. Programs like Hydro-Québec’s LogisVert can offer significant financial assistance, but eligibility always depends on the exact combination installed: indoor unit, outdoor unit, capacity, efficiency, and applicable reference number.
For a GREE LIVO R32, it is important to verify the exact system information before confirming a subsidy amount. At AirGreen, we assist customers in this verification to avoid misunderstandings. The invoice, model numbers, and technical documents must be consistent with program requirements at the time of application.
This approach is especially useful for customers comparing several brands and models. The installation price should not be analyzed alone. Efficiency, warranty, potential eligibility for financial aid, installation quality, and after-sales service must also be considered.
Mistakes to avoid when installing a wall unit in a condo or house in Chomedey
In this Laval area, we often work in homes where space is limited and installation constraints are many. Here are the most common mistakes we see when an installation has not been well planned.
Installing the indoor unit without considering the furniture
A unit may seem well placed on an empty wall but become problematic if a bed, sofa, or desk is directly in the airflow. Real comfort depends on the occupants' position.
Placing the unit too close to the ceiling
Insufficient space above the unit can hinder air circulation and complicate maintenance.
Neglecting the location of the outdoor unit
The outdoor unit must be installed in a stable, accessible location and comply with applicable regulations. Noise, clearance, snow, ice, and access for maintenance must be considered.
Choosing based on price alone
A cheaper installation can become costly if it causes drainage, vibration, performance, or service issues.
Forgetting regular maintenance
A wall system must be maintained. Filters need to be cleaned and periodic HVAC maintenance helps preserve the device's performance.
Usage tips to extend the lifespan of the GREE LIVO R32
After installation, we always recommend some good practices to the client. They are simple but very effective.
It is preferable to maintain a stable temperature rather than constantly turning the device off and on. In summer, a reasonable setting allows air conditioning while improving dehumidification. In heating mode, a gradual temperature increase is often more comfortable than an excessive and sudden demand.
Filters must be cleaned regularly. In a bright room, near a window or a frequently used space, dust can accumulate faster than expected. A clean filter allows better air circulation, reduces system effort, and improves comfort.
It is also important to avoid blocking the air outlet with curtains, tall furniture, or decorative objects. The wall heat pump works better when air can circulate freely.
