Installation of a Gree FreeMatch MultiZone heat pump in the Plateau-Mont-Royal (Montreal)

In the Plateau-Mont-Royal neighbourhood, projects often involve brick buildings with narrow rooms, old windows, and very specific design constraints: the goal is comfort… without “invading” the space. This is precisely the context of this AirGreen installation: a wall-mounted unit installed high up in an office/meeting room (suspended ceiling, whiteboard, stacked furniture), where efficient heating and cooling were required while maintaining a functional wall.

The chosen solution: a Gree FreeMatch MultiZone heat pump , perfect when you want to evolve comfort room by room (today one zone, tomorrow two or three), without starting from scratch.


Why a Gree FreeMatch in this type of space in the Plateau?

In an environment like this, the demand is clear:

  • Rapid cooling in summer (exposed room, solar gains through the window, occupants and equipment)

  • stable heating in mid-season and winter (constant comfort, fewer variations)

  • visual discretion (avoiding visible pipes and heavy construction work)

  • Flexibility if the occupancy changes (offices, service area, classroom, etc.)

The Gree FreeMatch system is particularly relevant because it integrates well into a “modular” approach: a multi-zone installation can be configured with precise management, while maintaining a clean aesthetic inside.


Type of machine installed

Here, we have a MultiZone heat pump (multi-zone mini-split) with a wall-mounted indoor unit .

Visually, we can recognize:

  • a white, horizontal wall-mounted head , installed high on the wall

  • a positioning designed to sweep the room without blowing directly into a fixed area

  • a typical “urban building” installation, where pipe runs are optimized to remain discreet


Model (realistic identification)

The image does not allow for the reading of a sign or a precise reference. Therefore, we are maintaining a consistent and accurate designation for this project:

  • Brand: Gree

  • Range/system: FreeMatch

  • Configuration: FreeMatch indoor wall unit (typical capacity suitable for a small to medium-sized room, often around 9,000 to 12,000 BTU depending on load calculation)

At AirGreen, this point is crucial: we don't "guess" a capacity randomly. It's validated through analysis (volume, insulation, windows, use, internal heat gains). In this type of room, the primary goal is stable and quiet comfort, without oversizing.


Prominent installation details that can be observed (and what that implies)

1) Installation at a height, close to the ceiling

The unit is placed high on the wall , under the suspended ceiling. This is good practice for:

  • improve air diffusion

  • avoid areas of direct airflow at occupant level

  • optimize heating performance (where hot air naturally tends to rise)

At AirGreen, we respect the recommended clearances (top, sides, facade) in order to preserve:

  • performance

  • ease of maintenance (filters, cleaning)

  • longevity

2) “Functional” wall: whiteboard and circulation

The wall is occupied by a whiteboard , which imposes a very precise placement logic: we want a wall-mounted head that does not interfere with the use of the board, nor with circulation, nor with visibility.

Result: placement above the active area , allowing the wall to remain usable while ensuring efficient airflow.

3) Proximity to a window (solar gain and comfort)

The window provides:

  • heat input in summer (and even in winter, at times)

  • variations in temperature and sensation near the glazing

The wall-mounted heat pump allows the room to be quickly stabilized , which is particularly appreciated in premises occupied intermittently.

4) Multi-zone approach: a smart decision for the future

Even though only one indoor unit is visible in the photo, the FreeMatch choice is strategic: in many buildings on the Plateau, needs change (remodeling, adding an office, converting a room). A multi-zone system allows for adding a zone later (depending on the configuration), rather than having multiple independent systems.


How AirGreen secures performance and sustainability

Load calculation and comfort calibration

In a neighborhood like Plateau-Mont-Royal, buildings often have:

  • variable building envelopes (brick, sometimes uneven insulation, partial renovations)

  • windows from different generations

  • rooms with changing uses

We therefore calibrate the solution for:

  • limit short cycles (comfort + efficiency)

  • to obtain useful heating in winter

  • maintain good dehumidification in the summer

Pipe management and clean finishing

In this type of environment, the quality of the installation is mainly evident in two things:

  • the routing of refrigerant lines (cleanliness, discretion, airtightness)

  • Condensate drainage (slope, safety, overflow prevention)

Even when part of the pipes are concealed, AirGreen applies strict standards: insulation, support, sealing, protection of penetrations (often through masonry), and careful finishing.

Noise and vibration reduction

A crucial point in the workplace: sound discretion .

  • Inside: positioning and adjustments to avoid unnecessary turbulence.

  • Outside (depending on the group's location): suitable supports, anti-vibration, and placement designed to reduce resonance on the structure.


What the occupier earns on a daily basis

  • Stable temperature without fluctuations (immediate comfort, especially when the room gets lively)

  • Effective cooling during hot periods

  • Efficient supplementary heating in mid-season and winter, depending on the chosen configuration

  • More pleasant air (better circulation, possibility of filtering dust through regular filter maintenance)

  • Scalability (the advantage of MultiZone FreeMatch: thinking beyond the piece of the day)


AirGreen maintenance advice for a wall-mounted unit in an “office/classroom” environment

To maintain performance:

  • Clean/inspect the filters at regular intervals (especially if the room is used frequently).

  • Seasonal inspection of the condensate drain

  • Regular professional maintenance: heat exchanger, turbine, general inspection, to prevent reduced flow and odors.

A well-maintained system is:

  • less noise

  • greater efficiency

  • a significantly improved lifespan


Conclusion: a coherent and clean choice for Plateau-Mont-Royal

This installation perfectly illustrates our approach at AirGreen: a solution tailored to the location , installed intelligently , with a discreet and effective result. The Gree FreeMatch , in a wall-mounted configuration, perfectly meets the needs of an urban space: rapid comfort, minimal footprint, and future flexibility.
