In Ville-Marie, you often come across mixed-use spaces (condos, common rooms, home offices, studios, finished basements) where comfort needs to be immediate, quiet, and easy to control. This is precisely the context for this AirGreen installation: a Gree Charmo wall-mounted heat pump installed high on a clear wall to ensure stable and even air distribution, both summer and winter.
The client's objective was clear: to provide efficient air conditioning during hot periods, while adding reliable supplementary heating capacity for the intermediate seasons — all with clean integration, without compromising the aesthetics of the room.
Why a wall-mounted heat pump in Ville-Marie?
In several buildings in Ville-Marie, the layout of the premises imposes concrete constraints:
-
Suspended ceilings (acoustic tiles) with limited technical spaces
-
finished walls (paint, plasterboard) where every passage must be planned
-
multipurpose rooms (meeting room, family room, open area) that require controlled air distribution
-
Need for silence (frequent occupation, activities, work, meetings)
The wall-mounted heat pump responds very well to these realities: it combines comfort , responsiveness , precise control and minimal footprint .
The chosen solution: Gree Charmo (wall-mounted / mini-split)
The brand supplied for this project is Gree Charmo — we treat it as the main reference for the installation and the writing of the file.
System type
This is a wall-mounted heat pump (mini-split) : an indoor wall unit that blows treated air, connected to an outdoor unit (not visible in the photo) via refrigerant lines and a condensation drain.
Why this type of device is relevant here
-
Rapid temperature rise/fall (immediate comfort)
-
Good temperature stability in an occupied room
-
Simple control (remote control / automatic modes depending on configuration)
-
Discreet format : the unit is installed high up, above the traffic area
Observable installation details: an installation designed for cleanliness and performance
The photo clearly shows an indoor unit installed very high , close to the ceiling. This choice is not only aesthetic; it is also a technical decision.
1) High placement = better distribution
In its raised position, the unit can:
-
project the air further
-
reduce localized “hot/cold” zones
-
prevent the airflow from directly hitting occupants seated nearby
In a room with rows of chairs (or any occupied area), this is a crucial point: we are looking for comfort, not a “draft”.
2) Technical management via suspended ceiling
Note the tiled ceiling and an open section (technical access). This type of configuration is very useful for:
-
plan the routing of technical elements
-
limit visible rework
-
to maintain a clean final result (without invasive work)
3) Clean and aligned installation
The unit is centered, above an open space, which facilitates:
-
maintenance (access to the filter, flaps, cleaning)
-
the operation (fewer obstacles in front of the blower)
-
sustainability (better circulation and less short-term recirculation)
Our AirGreen method: “clean” installation + complete commissioning
At AirGreen, a successful wall installation isn't just about "fixing your head to the wall." To achieve a truly lasting result (and avoid irritants), we follow a rigorous sequence:
Key milestones achieved on this type of project
-
validation of positioning (height, clearance, airflow trajectory)
-
wall mounting and leveling
-
Preparation of connections (refrigeration, electrical, drain) according to standards and best practices
-
leak testing and commissioning
-
Functionality check (modes, temperatures, airflow, noise, stability)
The result: an installation that inspires confidence, and a system that works as it should.
Comfort in all seasons: what the customer actually gains
In summer (air conditioning)
-
rapid drop in temperature
-
reduction in perceived humidity
-
improved stability during heat waves (very frequent in Montreal)
In mid-season (economical heating)
In neighborhoods like Ville-Marie, people often want to avoid overheating the entire building for a single room. A wall-mounted heat pump allows you to:
-
to heat as needed, where we live/work
-
to improve comfort without “pushing” another system
-
to obtain a more constant temperature, without large variations
Important points to consider in Ville-Marie (and which we always verify)
Each building has its own unique characteristics. In central areas, we pay particular attention to:
-
noise (choice of location, mounting, vibration, settings)
-
Aesthetics (discreet routes, clean finishes, integration into the decor)
-
future access (maintenance, cleaning, inspection)
-
Air circulation (avoid dead corners and obstacles)
It is often this “invisible” part of the work that makes all the difference between a correct installation… and a remarkable one.
Recommended maintenance for a Gree Charmo wall light
To maintain performance and air quality:
-
Filter cleaning (every 4 to 8 weeks during periods of intensive use)
-
Light cleaning of the panel and shutters (dust)
-
Seasonal checks: drainage, performance, noise, temperature stability
-
periodic professional maintenance (depending on usage, environment and occupancy)
A well-maintained system is:
-
fewer breakdowns
-
better yield
-
cleaner air
-
extended lifespan
Conclusion: an installation adapted to the reality of Ville-Marie
This Gree Charmo wall-mounted heat pump installed in Ville-Marie illustrates well what we aim for at AirGreen: a simple , efficient solution, neatly integrated into the space, with a positioning that promotes both performance and occupant comfort.
If you are in Montreal (Ville-Marie, Plateau, Rosemont, Southwest) or the surrounding area (Laval, South Shore, North Shore) and are looking for a wall installation that respects the constraints of your building — we can guide you to the right configuration, then install it with an impeccable finish.
