Installation of a Gree Charmo wall-mounted heat pump in Ville-Marie (Montreal)

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.
