Installation of a GREE LIVO R32 Wall-Mounted Heat Pump – Air Conditioner – Mini Split in Laval, in the heart of the North Shore
In Laval, AirGreen installs a GREE LIVO R32 wall-mounted heat pump with a sleek interior finish, high positioning, and precise comfort for residential air conditioning and heating.
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.
A discreet, clean wall installation designed for daily comfort in Laval
In Laval, our AirGreen team completed a HVAC installation that perfectly illustrates what many homeowners look for when choosing a wall heat pump: an efficient device, a discreet appearance, a clean installation, and constant comfort without altering the room’s aesthetics. In the photo, the GREE LIVO R32 indoor unit is installed high on a light wall, near the ceiling, in a very streamlined configuration. Nothing clutters the space. The device blends into the decor while being placed in a strategic location to promote good air distribution.
This type of installation seems simple at first glance. However, success depends on a series of precise technical decisions: mounting height, top clearance, wall strength, conduit routing, condensation drainage, refrigerant connection, commissioning, and explaining the operation to the client. A mini split heat pump is not just a device hung on the wall; it is a complete system that must be installed according to best practices to deliver its full performance.
The GREE LIVO R32 is a wall-mounted solution designed to provide air conditioning and heating in a targeted residential area. According to GREE, the LIVO R32 series can reach up to 20.5 SEER2, 12.5 EER2, and 8.8 HSPF2 depending on the installed combination; it uses the R32 refrigerant, offers a cooling range from 0 °F to 118 °F, and a heating range from -13 °F to 75 °F. These specifications make it an interesting option for residential projects in Laval, but also in Montreal, Longueuil, on the North Shore and the South Shore, when the client wants an effective wall air conditioner with a useful heating function for much of the year.
A high position on the wall for more natural air distribution
In this project, the indoor unit was installed high up on a clear wall. This choice is important. A unit that is too low can blow directly on occupants and create discomfort. A unit too close to the ceiling can hinder air return and complicate access to the front panel. Here, the location allows for more even diffusion in the room while maintaining a very discreet appearance.
The device is positioned above a clear wall, which helps air circulate without immediate obstacles. In a house or condo in Laval, this placement logic is essential, especially when treating a living area, bedroom, office, or open zone. The right location often allows for better comfort with less mechanical effort, as the unit does not need to compensate for a poor blowing angle or air circulation blocked by furniture.
At AirGreen, we always analyze the space before confirming the final position. We look at ceiling height, room layout, occupancy zones, presence of openings, sun exposure, and possible conduit routes. This step avoids common mistakes that can reduce the performance of a wall-mounted heat pump installation.
A minimalist interior finish that respects the room
The photo shows a very understated installation: a light wall, a white unit, a light visual presence, and no clutter around the device. This finish is often one of the most important criteria for customers. They want to improve their comfort without the HVAC system becoming the dominant element of the room.
The GREE LIVO R32 is well suited for this type of integration. Its wall-mounted design is simple, with a discreet front and clean lines. In this project, our team took care to align the unit consistently with the available space. A slightly offset installation or one too close to a corner may seem minor, but it is noticed every day. The precision of the installation is part of the final quality.
This attention to detail is especially important in residences in Laval, where customers often request installations in already furnished rooms: renovated living rooms, painted bedrooms, recent condos, home offices, or family spaces. Our goal is to deliver a HVAC installation that works well and respects the client's interior.
Why the GREE LIVO R32 suits the residential needs of Laval residents
The GREE LIVO R32 is designed for owners who want a reliable, easy-to-use wall system adapted to a specific area. It can serve as a wall air conditioner during the summer and as a heat pump during cooler periods. For a home in Laval, this improves comfort without having to modify the entire central heating or ventilation system.
Inverter technology is one of the important elements. Rather than operating only in abrupt on/off cycles, the system modulates its capacity according to demand. This helps maintain a more stable temperature and limits uncomfortable variations. In a sun-exposed room, in a condo with large windows, or in a bedroom that gets too hot at night, this modulation can make a noticeable difference.
The GREE documentation also mentions functions such as dehumidification, self-diagnosis, self-cleaning, the I-Feel function, multiple fan speeds, and control of the oscillating flap depending on the configuration. These functions are useful daily because they allow the device to adapt to the season, humidity level, and the customer's habits.
R32: a consistent choice with the new generations of mini splits
The installed model is part of the LIVO R32 family, which means it uses the R32 refrigerant. This refrigerant is now common in new generations of wall-mounted equipment. For the customer, the benefit lies in the system's efficiency and the more recent design of the device.
For AirGreen, installing an R32 unit requires the same rigor as any professional refrigeration work: well-made connections, properly insulated lines, leak testing, complete vacuuming, operation verification, and compliance with industry standards. The quality of a mini split heat pump never depends solely on its technical sheet. It also depends on how it is installed.
In this project in Laval, the visible interior finish is clean, but the invisible part matters just as much: routing of pipes, condensation drainage, protection of connections, and commissioning. A careful installation reduces the risks of noise, water leakage, performance loss, and premature interventions.
BTU capacity: a choice that must match the room
The exact installed capacity must always be confirmed according to the submission sheet and the indoor and outdoor model numbers. The GREE LIVO R32 range comes in several capacity formats, and the choice of BTU number must be adapted to the actual room, not just a quick area estimate.
At AirGreen, we specifically assess:
- the area to be cooled or heated;
- ceiling height;
- building insulation;
- the number of windows;
- sun exposure;
- air circulation between rooms;
- the humidity level;
- the use of the room;
- the customer's heating and cooling expectations.
A device that is too small will run too long and may not reach the requested temperature on very hot days. A device that is too large can cool quickly without properly dehumidifying, which sometimes gives a sensation of cold but uncomfortable air. Proper sizing is therefore one of the most important steps in a successful HVAC installation.
Subsidies and eligibility: check the exact model before promising an amount
Subsidies are often a decisive factor for customers comparing several options for wall-mounted heat pumps in Montreal, Laval, Longueuil, on the North Shore or the South Shore. Hydro-Québec specifies that heat pumps installed from November 26, 2025, must be ENERGY STAR certified to be eligible for financial assistance.
For a GREE LIVO R32, it is therefore necessary to validate the exact combination installed, the model numbers, the applicable certification, and the program rules at the time of the project. We always recommend keeping a detailed invoice, the indoor and outdoor model information, serial numbers, and required documents. At AirGreen, we support our clients so they clearly understand the steps to follow to submit their application when the device is eligible.
A GREE LIVO R32 installation in Laval that demonstrates the value of well-planned HVAC work
This project shows that a successful installation is not measured solely by the appearance of the unit. The photo shows a simple and clean finish, but behind this result is a precise working method. Every decision influences comfort, noise, performance, and system durability.
Wall preparation and choice of technical passage
Before mounting a wall unit, we must confirm that the wall can properly support the unit. The bracket must be stable, the location must allow pipe routing, and the drain must be reliably oriented. In some projects, the path to the outside is direct. In others, obstacles must be bypassed or a more complex structure worked with.
In Laval, residences are very diverse: bungalows, cottages, condos, plexes, renovated houses, and newer constructions. Each building has its own constraints. An installation that works in a house in Fabreville will not necessarily be the same as an installation in a condo in Laval-des-Rapides or a residence in Sainte-Dorothée. That’s why our approach is always adapted to the site.
Commissioning: the step that confirms the quality of the work
Once the indoor unit is installed and the system connected, commissioning confirms that everything is working properly. This step includes checking startup, airflow, drainage, operating modes, unusual noises, and basic settings.
We also explain to the client how to use their unit. This explanation is important because improper use can reduce comfort even with a good system. For example, it is best to avoid extreme settings, choose the right mode according to the season, and clean the filters regularly. Periodic HVAC maintenance also helps maintain the unit’s performance and extend its lifespan.
Mistakes to avoid when installing a wall air conditioner
This project highlights several common mistakes that homeowners should avoid when comparing quotes:
- choosing the unit based only on price;
- ignoring exact model numbers;
- installing the unit too close to the ceiling;
- placing the unit in a corner where air circulation is poor;
- neglecting the drain slope;
- accepting poorly protected pipe routing;
- forgetting future access for maintenance;
- not verifying actual eligibility for subsidies;
- comparing quotes that do not include the same work.
A wall-mounted heat pump is a comfort investment. The choice of model matters, but the quality of the installation matters just as much. A quick and rough installation can create problems that could have been avoided with better planning.
Comfort adapted to the realities of Laval
Clients in Laval often look for a solution that meets several needs: cooling a room during summer, improving bedroom comfort, reducing humidity, complementing an existing system, or adding an efficient heating source in a specific area. The GREE LIVO R32 responds well to this type of demand when properly sized and installed.
In this project, the indoor unit is placed to remain discreet while ensuring effective distribution. The client gets a unit that is easy to use, accessible for filter cleaning, and capable of improving comfort without major changes to the interior layout.

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.
