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.
An HVAC Installation in Saint-Bruno Where Precision Mattered as Much as Performance
In Saint-Bruno, on the South Shore, our AirGreen team completed the installation of a GREE CLIVIA R32 wall-mounted heat pump, used as a mini-split wall-mounted air conditioner, in a room undergoing renovation where several technical constraints had to be considered from the outset. The construction site image clearly shows the context: an interior wall still marked by openings, work benchmarks, a finish to be completed, a nearby window, and a wall unit installed high up, near the ceiling.
This type of project requires rigorous coordination between mechanical installation, interior finishing work, and the future use of the room. It's not just about mounting a white unit on a wall. It involves understanding the structure, anticipating the path of refrigerant lines, respecting necessary clearances, protecting the final aesthetic, and ensuring the system's proper functioning for several years.
In this Saint-Bruno residence, the client wanted a reliable solution to improve indoor comfort without compromising the ongoing renovation project. The GREE CLIVIA R32 proved to be a relevant option: compact, modern, efficient, and well-suited to the residential needs of the South Shore, where homeowners often seek a high-performance air conditioning solution for summer and efficient heating during cooler spring and autumn periods.
A GREE CLIVIA R32 Installed in a Space Undergoing Transformation
One of the most interesting aspects of this installation is its context. The room was not yet completely finalized at the time of installation. We observe an existing wall opening under the unit, traces of work on the ceiling, markings on the wall, and visible renovation elements in the room. For AirGreen, this kind of situation requires a different approach than an installation in a fully finished house.
Why Installing a Heat Pump During Renovation Can Be Advantageous
When an owner renovates a room, it is often the best time to integrate a wall-mounted heat pump. Walls may be more accessible, technical passages can be planned with more freedom, and finishes can then be adjusted around the installed equipment. This results in a cleaner final outcome than an improvised installation after the work is complete.
In this Saint-Bruno project, installing during renovation allowed for better coordination of:
- the exact positioning of the indoor unit;
- the routing of conduits and drain;
- future wall repair;
- access near the window;
- integration of the final finish around the appliance;
- protection of the unit during the remaining stages of the construction.
This planning is essential. A well-executed HVAC installation must consider not only the immediate operation of the appliance but also the final state of the room after painting, plastering, carpentry, or fitting out.
The Choice of Wall and Installation Height
The GREE CLIVIA R32 indoor unit was installed high up, near the ceiling, on a clear wall located near a window. This choice allows for good air diffusion in the room, while freeing up lower wall space for furniture or future fittings.
However, installing a unit near the ceiling requires special attention. The heat pump must have sufficient clearance to draw air properly from above. If it is placed too close to the ceiling, air circulation can be limited, which reduces efficiency, increases fan effort, and can affect comfort. Our technicians therefore adjusted the position to maintain a balance between available height, aesthetics, and the manufacturer's technical requirements.
The wall also showed signs of previous work, including a visible circular opening under the appliance. This detail had to be taken into consideration to avoid weakened areas and ensure solid mounting of the wall plate.
Solid Mounting Despite a Wall Under Construction
In a room undergoing renovation, walls can hold surprises: irregular studs, old openings, partial repairs, existing conduits, wiring, or weakened materials. Before installing the unit, our team checked the mounting location to ensure the appliance would be securely anchored.
An indoor wall unit is not extremely heavy, but it must remain perfectly stable. An imprecise mounting can cause vibrations, noises, misalignment, or unnecessary pressure on refrigerant connections. In the case of this Saint-Bruno installation, mounting precision was all the more important as finishing work would continue after installation.
Our goal was clear: to install the unit permanently, stably, and aligned, so that the subsequent renovation stages could proceed around an already well-positioned system.
Routing of Refrigerant Lines and Drain
The success of an HVAC installation largely depends on what is not seen. Behind or around a wall unit, several elements must be correctly installed: refrigerant lines, communication cable, power supply, condensate drain, and the passage to the outside.
In this installation, the presence of a window on the left and the wall configuration influenced the possible routing. A logical, safe, and durable path had to be chosen, while respecting the building's constraints. The drain, in particular, had to be carefully thought out. In air conditioning mode, the wall-mounted air conditioner removes moisture from the air, and this water must drain without stagnation.
An improperly calculated slope, an overly compressed drain, or an unprotected passage can lead to problems: insufficient flow, odor return, internal leakage, or water accumulation. At AirGreen, we systematically check drainage during commissioning, as it is one of the most important points to ensure client peace of mind.
Advantages of R32 Refrigerant
The GREE CLIVIA R32 model uses R32 refrigerant, a technology increasingly present in modern wall-mounted systems. This refrigerant is appreciated for its energy efficiency and performance in new generation appliances. For homeowners in Saint-Bruno, Montreal, Laval, Longueuil, the North Shore, and the South Shore, it represents an interesting option when looking for more modern and high-performing equipment.
In this project, the appeal of R32 was linked to three aspects:
- better potential efficiency in a properly sized system;
- a modern design suitable for residential installations;
- compatibility with current HVAC performance expectations.
However, the choice of a wall-mounted heat pump should never be based solely on refrigerant technology. Sizing, installation quality, indoor unit placement, and commissioning are equally important.
A Solution Designed for Daily Comfort
The GREE CLIVIA R32 meets a very concrete need: to offer better temperature control in a room that, once renovated, will be regularly used. In many Saint-Bruno homes, rooms located near a large window can be warmer in summer due to sunlight, or cooler in winter depending on insulation and the age of the openings. The addition of a wall-mounted heat pump allows for stabilizing comfort without having to modify the entire existing heating system.
The client wanted a discreet, yet effective solution. The white indoor unit integrates well with the wall and can become even more discreet once plastering and painting are completed. This is one of the advantages of an installation carried out during a renovation: the appliance can be integrated into the final vision of the room instead of being added as an afterthought as a compromise.
A Clean Installation Despite a Construction Environment
Even when the room is under construction, our teams maintain the same standards of cleanliness and rigor. Surfaces must be protected, drillings must be controlled, debris must be limited, and the unit must be installed in a way that it is not damaged by subsequent stages of the construction.
In this Saint-Bruno installation, the environment already showed several traces of renovation: marks on the wall, circular opening, ceiling to be redone, and materials present in the room. Our role was to add the HVAC system without worsening the condition of the wall or complicating the work of other trades.
Simple, but important coordination was applied: placing the appliance in the right place, maintaining necessary access, checking connections, and then leaving a sufficiently clear environment for finishes to continue.
Mistakes to Avoid in a Wall Installation During Renovation
This project illustrates several common mistakes homeowners should avoid when installing a mini-split wall-mounted air conditioner during work.
Installing the unit before confirming the final layout
Before installing a unit, it is necessary to know where furniture, shelves, curtains, cabinets, or future wall elements will be placed. A well-placed unit today can become an inconvenience if the final layout has not been considered.
Forgetting about future wall repairs
In a room under renovation, walls will often be re-plastered or repainted. The unit must be installed in a way that allows for a clean finish around the appliance, without having to unnecessarily dismantle it.
Underestimating the importance of the drain
A poorly planned drain is one of the most common causes of post-installation problems. In a renovation, it can be tempting to quickly conceal conduits, but drainage must always remain a priority.
Choosing capacity without analysis
A heat pump that is too large or too small can reduce comfort. The choice must be made based on the area, insulation, room orientation, ceiling height, and the client's actual needs.
Neglecting access for HVAC maintenance
Even in a well-renovated room, filters will need to be cleaned. The unit must remain accessible for HVAC maintenance, inspections, and future cleanings.
The Role of Sizing in Performance
For this installation in Saint-Bruno, as for all our installations, the choice of system must match the reality of the room. A wall-mounted unit works best when it can modulate correctly, maintain a stable temperature, and manage humidity without excessively short cycles.
During the evaluation, we take into account several factors:
- room area;
- number of windows;
- sun exposure;
- insulation quality;
- ceiling height;
- air circulation to adjacent rooms;
- intended use of the space;
- desired sound level;
- heating and cooling needs.
In Saint-Bruno, many homes have renovated rooms, extensions, converted basements, or spaces with large windows. These specificities directly influence the choice of the wall-mounted heat pump.
Subsidies and Potential Eligibility
Depending on the exact model, installed capacity, and current criteria, certain wall-mounted heat pumps may be eligible for subsidy programs, particularly when the appliances meet applicable energy efficiency requirements. At AirGreen, we help our clients understand the necessary documents, such as invoices, model information, and references required to submit an application when the system is eligible.
It is important to specify that eligibility always depends on the criteria in force at the time of installation. Homeowners in Montreal, Laval, Longueuil, the North Shore, and the South Shore should verify these elements before making a final decision, especially when the goal is to reduce the net cost of the project after financial aid.
AirGreen Expertise Adapted to Residential Construction Sites
This project demonstrates the importance of working with a team accustomed to the realities of homes undergoing renovation. An installation in an already finished room requires delicacy. An installation in a room under construction requires anticipation. In both cases, expertise makes a difference.
At AirGreen, we regularly carry out installations in homes under transformation in Saint-Bruno, Brossard, Longueuil, Laval, Montreal, on the North Shore, and on the South Shore. We know that a residential construction site evolves quickly and that every technical decision must take into account what will be done after our visit.
In this GREE CLIVIA R32 installation, our team paid particular attention to alignment, upper clearance, wall support, conduit routing, and compatibility with finishing work. These details ensure a lasting result.
Lasting Comfort for a Soon-to-be-Finished Room
Once the renovation is complete, this room will benefit from a modern, discreet, and efficient comfort system. The wall-mounted unit installed high up will air condition the space during hot days and add heating during cooler periods. The client will enjoy more precise temperature control, without having to rely solely on the existing house system.
The GREE CLIVIA R32 wall-mounted heat pump is well-suited to this type of project, as it offers a good balance between performance, discretion, and installation flexibility. In a room where wall space is limited by a window, ongoing work, and future layouts, this flexibility becomes a real advantage.
Practical Advice for Saint-Bruno Homeowners
For homeowners considering an HVAC installation during a renovation, a few recommendations can avoid many complications:
-
Plan the installation before wall finishing.
This allows for better integration of conduit passages and avoids unnecessary rework. -
Validate the location with the final layout plan.
The unit must not interfere with planned furniture, curtains, light fixtures, or storage. -
Maintain access to the unit.
Filters, the front panel, and components must remain accessible. -
Do not neglect condensation drainage.
The drain must be installed with an adequate slope and properly tested. -
Choose a team specializing in residential HVAC.
A high-performance appliance will only deliver its full potential if installed rigorously.
An installation that prepares the room for years to come
This installation of a GREE CLIVIA R32 wall-mounted heat pump in Saint-Bruno perfectly illustrates the value of a well-planned intervention in a renovation context. The unit was installed at the right time, in the right place, with particular attention to the constraints of the wall, ceiling, window, and upcoming work.
For AirGreen, a successful installation is not limited to starting the machine. It must integrate into the home, respect the construction stages, meet comfort needs, and remain reliable over time. This project in Saint-Bruno reflects this approach: a well-positioned heat pump, a clean installation, and a solution adapted to the residential realities of the South Shore.
Whether in Montreal, Laval, Longueuil, on the North Shore or on the South Shore, we apply the same rigor to every project. The GREE CLIVIA R32 installed here is an excellent example: a modern system, carefully integrated, ready to offer lasting comfort once the renovation is complete.

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.
