A neat indoor wall installation in a space where every centimeter counted
In Senneville, this installation of a GREE LIVO R32 wall heat pump highlights an essential aspect of our work at AirGreen: integrating a high-performance HVAC system into an existing residential space without compromising aesthetics, indoor flow, or daily use of the room. In the photo, you can see the GREE indoor unit installed very close to the ceiling, in a simple wall corner, with the louvers open and the unit running. The installation is clean, discreet, and well aligned, which is particularly important in a home where interior appearance matters as much as technical performance.
In this project, the client wanted to improve the thermal comfort of a specific area of the residence without undertaking major work or modifying the entire building's mechanical system. A mini split wall heat pump was therefore a logical solution: a compact, efficient device capable of cooling in summer and providing heating according to seasonal needs. The GREE LIVO R32 was chosen for its balance between comfort, ease of use, efficiency, and wall integration.
In Senneville, houses can have very varied configurations: open rooms, sloped or low ceilings depending on the areas, successive renovations, limited available walls, spaces where adding ducts would be too invasive. This reality requires a custom approach. At AirGreen, we never choose a location at random. We analyze air circulation, available height, duct routing, maintenance access, drainage, and the position of the outdoor unit before finalizing the installation.
An indoor unit placed high to free up space and optimize diffusion
The photo shows a high installation, near the ceiling, with a white wall unit that blends into a light decor. This positioning is common for a wall air conditioner, but it must be done carefully. A unit placed too close to the ceiling may lack air intake, become difficult to maintain, or lose efficiency. Conversely, a well-calculated installation allows the use of a less useful wall area while ensuring comfortable diffusion in the room.
In this project in Senneville, our team paid special attention to several elements:
- clearance above the unit to allow good air intake;
- alignment of the unit for a neat interior finish;
- the direction of the airflow to avoid an uncomfortable direct draft;
- the passage of refrigerant lines to the outside;
- the slope necessary for condensation drainage;
- future access to filters for HVAC maintenance;
- visual integration into a neat residential space.
The GREE LIVO R32 installed here is not simply fixed to the wall: it is positioned to operate efficiently in the real context of the house. This nuance makes all the difference between an acceptable installation and a truly sustainable installation.
Why the GREE LIVO R32 was suitable for this project in Senneville
The GREE LIVO R32 is a wall-mounted heat pump designed to offer a good level of comfort in residences where one wants to heat and cool a specific area without installing ducts. Its wall format, clean appearance, and relatively quiet operation make it a very interesting option for bedrooms, living rooms, offices, living areas, finished basements, or areas difficult to balance with the existing heating system.
The refrigerant R32 is an important technical element. It is used in several recent HVAC devices and allows good heat transfer. For the owner, this means the device belongs to a modern generation of mini splits, with a design focused on efficiency, reliability, and daily residential use.
Since the exact BTU capacity must always be confirmed according to the device's nameplate and the room's heat load, our team validated the sizing before installation. This point is essential. A heat pump that is too small risks running too long without reaching the desired comfort. A unit that is too large can create short cycles, less stable dehumidification in summer, and a less uniform temperature sensation.
For this project, the selection criteria included:
- a capacity suited to the actual area to be treated;
- a compact wall-mounted installation;
- good air distribution in the room;
- easy use for the customer;
- a ductless heating and cooling solution;
- an appropriate noise level for a residential space;
- compatibility with the architectural constraints of the house.
A discreet HVAC installation, but technically demanding
A HVAC installation of a mini split may seem simple once completed. Yet, behind the clean appearance of the indoor unit, several technical steps determine the quality of the result. In this installation in Senneville, each operation was carried out with the goal of ensuring stable and durable operation.
Our intervention notably included:
- analyzing the room and wall location;
- validating clearance around the indoor unit;
- identifying the best route for refrigerant lines;
- preparing the passage to the outside;
- leveling and securing the wall mount;
- installing the GREE LIVO R32 indoor unit;
- connecting refrigerant lines;
- checking condensation drainage;
- vacuuming the refrigeration circuit;
- tests in air conditioning and heating mode;
- explaining the use to the client.
Vacuuming is a particularly important step. It removes moisture and air from the refrigeration circuit before commissioning. Neglecting this step in installation can cause performance loss, premature wear, and reliability issues. At AirGreen, this type of check is part of our working method, whether for an installation in Montréal or a project in Laval, Longueuil, on the North Shore or the South Shore.
The specific constraints observed in this installation
The image shows a unit placed near a corner and a ceiling, in an area where access had to be used smartly. This kind of situation requires good coordination between aesthetics and technical aspects. The goal was not only to fit the device into the available space but to place it where it could actually function well.
We therefore took into account three main factors.
The upper clearance
Even if the device is near the ceiling, it must maintain the necessary space to draw in ambient air. This air passes through the upper part of the unit, then is treated before being blown into the room. Insufficient clearance can reduce efficiency and force the device to work harder.
The direction of the airflow
The open shutters visible in the photo show that the unit is ready to direct air towards the area to be treated. The orientation must be adjusted to promote an even temperature, without sending air directly onto a seated person, a bed, or a passageway that is too narrow.
Access to the filters
Good HVAC maintenance starts with reasonable access to the filters. In a residence, filters must be removable, cleanable, and replaceable without excessive difficulty. When a device is installed too high or too tight, this maintenance becomes less frequent, which eventually harms performance.
What Senneville homeowners need to know before installing a wall heat pump
A GREE LIVO R32 wall heat pump can offer excellent comfort, but the result strongly depends on project preparation. In Senneville, as in many areas of the West Island, houses often have particular interior volumes, customized renovations, and high expectations regarding the final appearance. A well-thought-out installation must therefore consider the building, the room’s use, and the client’s habits.
Air conditioning in summer and heating in cold season
The GREE LIVO R32 acts both as a wall air conditioner and as a heat pump. In summer, it helps reduce temperature and control humidity, which is very useful during heat periods in the Montreal area. For heating, it can serve as an effective comfort source depending on outdoor conditions and the house layout.
In many residences, this type of system is used as a complement to the main heating. It allows better control of a particular area, for example a room that gets too hot in the sun, an upstairs bedroom, a home office, or a family space that does not receive enough uniform heating.
A relevant solution when ducts are not desired
Adding ducts in an existing house can be costly and invasive. It may require opening walls, ceilings, or soffits, with additional finishing work. The mini split system avoids these heavy interventions while offering targeted comfort.
In this project in Senneville, the wall installation allowed adding a heating and air conditioning solution without altering the interior structure. The unit occupies a high area of the wall, preserves floor space, and integrates into an already furnished room.
Mistakes to avoid in a wall-mounted heat pump installation
Our field experience allows us to quickly recognize mistakes that can compromise an installation.
Choosing the location based only on appearance
Aesthetics are important, but they should never replace technical logic. A very discreet device, but poorly positioned, can result in disappointing comfort.
Installing the unit without checking air circulation
Air must be able to enter and exit freely. A wall too close, a ceiling too near, or an obstacle in front of the unit can harm performance.
Underestimating the importance of drainage
In cooling mode, the indoor unit produces condensation. This water must be drained with an adequate slope. Poor drainage can cause leaks and interior damage.
Neglecting capacity choice
The number of BTUs must be chosen based on a serious evaluation. Area alone is not enough. Insulation, sunlight, ceiling height, windows, and room usage must also be considered.
Postponing maintenance for too long
Dirty filters reduce airflow, increase the device’s effort, and can decrease comfort. Regular maintenance remains one of the simplest ways to protect the investment.
Grants and eligibility: verify the exact model before committing
Financial aid programs for wall-mounted heat pumps can represent a significant advantage for owners, but eligibility always depends on the exact model, capacity, AHRI number, technical criteria, and rules in effect at the time of installation. For a GREE LIVO R32, we always recommend verifying the precise information before confirming an amount or eligibility.
At AirGreen, we assist clients with this verification when applicable. We help gather technical information, the invoice, and necessary documents so the owner can submit their file correctly. This process is useful for clients in Senneville, but also for those in Montréal, Laval, Longueuil, the North Shore, and the South Shore.
The AirGreen experience on this project
For this installation in Senneville, our priority was to deliver a clean, functional, and durable result. The client wanted an efficient solution, but without a bulky device in the middle of the room or major changes to the layout. We therefore chose a strategic wall location, installed the unit precisely, and tested the system before the final handover.
Once the installation was completed, we explained the basic settings, operating modes, filter maintenance, and good usage practices. This moment is important because a well-used device generally provides better comfort and better efficiency.
We especially recommend:
- to avoid too frequent temperature changes;
- to keep the filters clean;
- not to block the airflow with furniture or curtains;
- to use the appropriate mode according to the season;
- to have the system checked if an unusual noise or smell appears;
- to schedule professional maintenance according to usage intensity.

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.
