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 and efficient wall installation to improve the comfort of a residence in Vaudreuil-Dorion
In Vaudreuil-Dorion, a residence located in an area where temperature variations are quickly felt between humid summer days and cold autumn evenings needed a simple, reliable, and well-integrated solution to stabilize indoor comfort. The choice fell on a wall-mounted heat pump GREE LIVO R32, a mini split air conditioner system designed to offer a good balance between performance, visual discretion, and energy efficiency.
At AirGreen, we carried out this HVAC installation with particular attention to the location of the indoor unit, the cleanliness of the duct passage, the strength of the wall anchoring, and the final appearance. As can be seen in the image, the GREE indoor unit was installed high up, with a clean finish, straight positioning, and a glossy white front that naturally blends into the interior decor.
This type of installation is common in houses, condos, and apartments in Vaudreuil-Dorion, but each project requires a different analysis. The goal is never just to “install a machine on the wall.” The right location must be chosen, good air circulation ensured, noise disturbances avoided, the building structure protected, and the system’s performance guaranteed to remain stable for several years.
Why the GREE LIVO R32 was well suited for this project
The GREE LIVO R32 is a wall-mounted heat pump appreciated for its compact design, relatively quiet operation, and its ability to provide both heating and cooling in a single solution. In a residential context in Vaudreuil-Dorion, it meets the needs of a homeowner who wants to improve comfort without undertaking invasive work.
The system is based on a mini split type technology, meaning a wall-mounted indoor unit connected to an outdoor unit by refrigerant lines, a communication cable, and a condensation drain. This setup allows for air conditioning and heating of a specific area without the need for a complete duct network throughout the house.
The refrigerant R32 also represents an important advantage. It is now used in several recent models of wall-mounted heat pumps to improve thermal transfer efficiency while meeting evolving HVAC standards. For customers comparing different systems in Montreal, Laval, Longueuil, on the North Shore or the South Shore, this technical detail is often reassuring, especially when they want a durable installation better suited to current equipment.
An indoor unit installed with particular attention to clearance
The image shows an indoor unit positioned high on the wall, near the ceiling, with a well-cleared front air outlet. This detail is essential. A wall-mounted heat pump must be able to draw ambient air from the top and redistribute treated air from the front, without any immediate obstacle that could hinder airflow.
During this installation in Vaudreuil-Dorion, our team paid special attention to several points:
- the clearance above the unit and the ceiling;
- the horizontal alignment of the device;
- future access to filters for HVAC maintenance;
- the direction of airflow in the room;
- the discreet routing of pipes and cables;
- the sturdiness of the wall mount;
- the natural and safe drainage of condensation.
A poor location can cause several problems: discomfort, too short cycles, abnormal noise, poorly drained condensation, reduced performance, or maintenance difficulties. That is why our team never limits itself to the "easiest" place to install the unit. We look for the most logical spot for the customer's comfort, equipment durability, and the final quality of the installation.
The main challenge: a clean installation in a visible space
In this project, one of the most important points was the final appearance. The indoor unit is located in a visible space, which requires careful installation. A wall-mounted heat pump that is misaligned or surrounded by poorly placed ducts can quickly give the impression of sloppy work, even if the device functions properly.
Our approach was therefore to work precisely from the start. Before drilling, we validated the installation axis, the necessary slope for drainage, the technical path to the outside, and the visual impact of the unit once installed. The result is a neatly integrated device, with a uniform front, discreet display, and clear air outlet.
This kind of detail makes a big difference for clients. A successful installation must be efficient, but it must also respect the interior of the residence. At AirGreen, we believe a well-installed HVAC system should be noticed for its comfort, not for finishing defects.
A solution adapted to the real needs of the home
Before recommending a GREE LIVO R32, it is necessary to understand the actual use of the space. In many homes in Vaudreuil-Dorion, owners want to air condition an open area, a living room, a main floor, or a particularly uncomfortable zone in summer. Others mainly want to reduce dependence on traditional electric heating during milder periods.
The GREE LIVO R32 wall heat pump can meet these two needs, provided the capacity is well chosen. A unit that is too weak risks running too long without reaching the desired comfort. A unit that is too strong can cause short cycles, poorly controlled humidity, and premature wear. That is why we always evaluate the area, insulation, solar orientation, number of windows, ceiling height, and room layout.
In this case, the objective was to achieve stable comfort without complicating the building. The wall system effectively targets the main area while maintaining a simple, quick, and less intrusive installation than a central system.
The key steps of this HVAC installation in Vaudreuil-Dorion
An installation of a wall air conditioner or a mini split heat pump follows a precise sequence. Each step influences the final performance of the system.
1. Analysis of the indoor location
We first validated the wall chosen for the indoor unit. The goal was to promote good air distribution while keeping the device accessible for filter cleaning. The unit had to be installed high enough to optimize airflow but not so high as to make maintenance difficult.
2. Preparation for the refrigeration passage
The passage between the inside and outside must be done cleanly, with an adequate slope for condensation water drainage. A poor slope can cause backflow, dripping inside, or odors over time. In a professional installation, this point is checked before finalization.
3. Installation of the GREE indoor unit
The wall unit was mounted on its mounting plate with precise alignment. The positioning was checked to ensure a straight appearance and good stability. The device must remain perfectly in place even after several years of operation, light vibrations, and seasonal cycles.
4. Connection to the outdoor unit
The refrigerant lines, wiring, and drain were then connected according to best industry practices. In a quality HVAC installation, connections are protected, lines are well insulated, and the layout is organized to avoid performance losses.
5. Startup and checks
Once the installation is complete, our team conducts tests: startup, operating modes, output temperature, drainage, noise, remote control response, and overall stability. These checks confirm that the GREE heat pump is working properly before leaving the site.
What customers notice after installation
After installing a GREE LIVO R32 wall-mounted heat pump, customers generally notice three immediate changes.
The first is comfort. The air becomes more stable, especially in areas where the old system was insufficient. The second is the relative quietness of the indoor unit, especially when the device runs at low speed. The third is ease of use: the temperature is controlled directly, without having to adjust multiple baseboards or open windows to compensate for temperature differences.
In Vaudreuil-Dorion, where many homes have open areas, extensions, or sun-exposed rooms, this type of system can make a big difference in daily life. It’s not just about cooling the air in summer. A good wall-mounted heat pump improves comfort management all year round.
What this installation reveals about the importance of well-executed HVAC work
A high-performance wall-mounted heat pump depends as much on the machine as on the quality of the installation. Even a good model can deliver disappointing results if the location is poorly chosen, if the ducts are poorly insulated, if drainage is neglected, or if the commissioning is rushed.
Mistakes to avoid with a wall heat pump
Many clients contact us after seeing problematic installations elsewhere. The most frequent mistakes are often the same:
- indoor unit installed too close to the ceiling;
- device not properly leveled;
- drain without sufficient slope;
- pipes poorly protected outside;
- capacity poorly matched to the room;
- outdoor unit installed in a space that is too confined;
- lack of a complete check after startup;
- filter maintenance forgotten for several months.
These mistakes can reduce the device’s lifespan and harm comfort. At AirGreen, we emphasize preparation because a good result depends on details that are not always visible in the final photo.
Recommended maintenance for a GREE LIVO R32
To maintain the performance of a GREE wall air conditioner, regular maintenance is essential. The client must clean the indoor unit’s filters according to usage, especially during periods of heavy air conditioning. Periodic professional checks also ensure the drain remains clear, the exchanger stays clean, and the system maintains good efficiency.
Good HVAC maintenance helps prevent odors, performance losses, water leaks, and unusual noises. It also helps extend the lifespan of the heat pump, which is particularly important in a climate like Greater Montreal’s.
Grants and eligibility: a point to verify precisely
Grant programs can represent a significant advantage for homeowners installing a heat pump in Quebec. However, eligibility depends on the exact model, the indoor/outdoor combination, applicable certification numbers, installed capacity, and the criteria in effect at the time of the application.
For this reason, at AirGreen, we always verify eligibility information before presenting a final recommendation. For a client in Vaudreuil-Dorion, as for a client in Montreal, Laval, Longueuil, on the North Shore or the South Shore, this check helps avoid unpleasant surprises and better understand the real cost of the project after available aids.

What would it look like 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.

Your own project, step by step
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
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.
