In the Southwest, many new condos have narrow balconies, modern facades, and very real space constraints. This is precisely the context for this AirGreen installation: a Gree FreeMatch heat pump (multi-zone system) installed on a terrace/balcony, with particular attention paid to noise, air vents, snow protection, and the finishing of wall penetrations.
Our goal here was simple: to offer stable comfort, summer and winter, while respecting the aesthetics of the balcony and the condominium requirements.
An ideal solution for condos: the Gree FreeMatch (multi-zone)
The Gree FreeMatch range is designed for homes where you want to heat and cool several zones (e.g., living room + bedroom, or two floors) with a single outdoor unit . In urban areas like the Southwest of France, this is often the cleanest and most logical option: less outdoor equipment, less clutter, and zone-by-zone comfort control.
Why this type of system is particularly relevant in Montreal
-
Rapid weather changes (mid-season): we often go from heating to cooling in a few days.
-
Different needs depending on the room : a bedroom does not have the same needs as a glass-enclosed living room.
-
Energy optimization : a well-sized multi-zone system avoids unnecessary overheating/overcooling.
-
Façade constraints : a single external compressor is often easier to get accepted (according to regulations).
The location: The Southwest, between urban density and balconies “counted down to the centimeter”
The Southwest (think Griffintown, Saint-Henri, Little Burgundy) combines modern buildings with older ones. In this project, the development is clearly in a condo -type environment, where:
-
The space on the terrace is limited.
-
Access is more restricted than a backyard.
-
Noise and vibration management is crucial.
-
Aesthetics matter as much as performance.
This is precisely where AirGreen makes the difference: a carefully designed installation, built to last, and above all designed to avoid irritants (neighborhood noise, vibrations, condensation, insufficient ventilation, etc.).
Visible installation details: what the image reveals (and why it matters)
In the photo, several elements speak for themselves — and these are exactly the points we monitor in every installation.
1) Outdoor unit on a raised support (balcony/terrace)
The outdoor unit is mounted on a raised metal stand . This is a very suitable choice in Greater Montreal.
-
The unit is protected against water, ice, and blowing snow.
-
Drainage is improved and accumulation under the base is limited.
-
This reduces the risk of premature corrosion.
2) Air clearances and intelligent positioning
Even on a balcony, the device needs to breathe. Positioning takes into account:
-
of the fan's airflow ,
-
minimum distances from the wall and partitions,
-
avoiding a too closed “corner” (which would recirculate the air and lower the efficiency).
3) Wall penetration of refrigerant lines: insulation + sealing
You can see the pipes exiting towards the wall with protection (sheath/insulation) and a sealed penetration. This is essential for:
-
prevent air and moisture infiltration,
-
limit energy losses,
-
avoid pests,
-
maintain a clean finish (especially in a condominium).
4) Clear electrical section with disconnect box
The disconnect box near the unit is a point of compliance and safety. For us, this is non-negotiable: access, height, fixing, and clean routing.
5) Vibration and noise management
On a balcony, the structure can amplify vibrations. In this type of project, we pay attention to:
-
the quality of the support,
-
stability,
-
the points of contact,
-
minimizing resonance (especially near a patio door).
Model: realistic and consistent identification
The exact label is not legible in the photo, but the brand provided manually is our confirmation: Gree FreeMatch . In this condo setting, the most logical scenario is a FreeMatch R32 outdoor unit designed for 2 or 3 zones , typically in the 30,000 to 42,000 BTU range depending on the indoor configuration.
Beyond the exact number, what matters is the sizing: at AirGreen, we don't "guess" blindly. We aim for a capacity aligned with:
-
the area,
-
sunlight (frequent glazing in condos),
-
insulation,
-
orientation,
-
lifestyle habits,
-
and the desired comfort in winter.
Key steps in our AirGreen approach (which avoids 90% of the problems)
1) Validate the location (before drilling, before fixing)
On the balcony, we check:
-
access for maintenance
-
air vents,
-
protection against snow/ice accumulation,
-
neighborhood (noise),
-
condominium constraints.
2) Fixing and leveling
An unevenly leveled compressor can:
-
to vibrate more,
-
wear out faster,
-
drains less well during defrosting.
Here, the raised base and structure indicate an installation designed for stability.
3) Refrigeration connections and finishing
A clean wall crossing is:
-
less risk of infiltration,
-
an aesthetically pleasing result
-
superior durability (the “beautiful” here also protects the “good”).
4) Commissioning and checks
Once the installation is complete, we confirm:
-
pressures and operation,
-
behavior in heating mode
-
reaction during defrosting,
-
temperature stability
-
noise heard on the terrace.
Everyday comfort: what the customer actually gains
With a properly installed Gree FreeMatch , the customer obtains:
-
a more stable temperature
-
zone control (depending on the interior layout),
-
efficient operation in air conditioning,
-
comfortable heating in Quebec winters,
-
a reduction of typical discomforts (rooms too hot / too cold).
And above all: an installation that "goes unnoticed". Because the best HVAC system is the one you no longer think about.
Common mistakes when using a balcony (and how to avoid them)
In urban areas, we often see installations that end up causing problems. Here are some classic examples:
-
Unit too close to the wall → loss of efficiency, air recirculation.
-
Improvised support → vibrations, noise, neighborhood complaints.
-
Non-watertight penetration → infiltration, humidity, degradation.
-
"Sloppy" pipe routing → questionable aesthetics, mechanical risk.
-
Maintenance access impossible → neglected maintenance, more frequent breakdowns.
On this project, we see instead a logic of sustainability: solid support, clean positioning, controlled crossing.
Why have a Gree FreeMatch installed by AirGreen in the Southwest?
Because in a condo, details matter twice as much:
-
We install it in a shared, visible, and enclosed space.
-
We want efficiency, but also silence.
-
We want a clean finish.
-
and we want a result that respects the building as much as the client.
At AirGreen , we adapt to the terrain: terrace, balcony, party wall, restricted space — and we maintain the same standard of quality.
