In many typical Rosemont–La Petite-Patrie buildings—brick duplexes and triplexes, renovated in phases, with sometimes cramped mechanical spaces—the challenge isn't simply "installing a unit." The real issue is integrating a high-performance system without sacrificing aesthetics , while ensuring uniform air distribution and easy access for maintenance. This is precisely the context of this AirGreen installation: a Gree ducted system (concealed indoor unit) integrated into an existing structure, using a clean and sustainable approach.
Why choose a ducted system for residential use in Montreal?
A ducted (concealed) system is an ideal solution when you want to:
-
To heat and cool multiple rooms evenly
-
Reduce visual clutter (no large wall-mounted headboard in the living room)
-
Improve comfort through gentler and better distributed diffusion
-
Working with existing ducts (or creating new ones) during a renovation
In a neighborhood like Rosemont, where each dwelling has its own configuration (ceilings, partitions, stairwells, divisions), ducted systems allow for customized integration : discreet grilles, well-positioned air return, and optimized circulation.
The chosen solution: Gree Ducted (concealed indoor unit)
The brand installed here is Gree , in a ducted version. Specifically, it's an indoor unit of the box type installed in a technical space (mechanical cupboard / soffit / framed area), designed to supply a network of ducts.
Even when the exact model is not visible in the photo, the configuration is consistent with a modern residential “central” approach such as the Gree ducted air manager , often selected for:
-
its compatibility with compact ductwork systems
-
its silent operation
-
its ability to maintain a stable temperature despite the typical variations of our climate
Observable installation details: what really matters
The photo shows a Gree unit installed in a wood-framed cavity, typical of a space undergoing renovation or refurbishment (exposed structure, direct access to the equipment). This type of situation is common in Montreal: modernization is carried out one section at a time, and the existing structure must be integrated with the new.
Here are the key points that AirGreen systematically manages in this type of installation:
1) Integration into a restricted space (and future access)
A ducted unit must remain accessible : filter, drain, electrical compartment, service panel.
In a framework like this, we plan:
-
a realistic clearance area for maintenance
-
access without repeated disassembly
-
a service logic that avoids unnecessary calls later
2) Condensation management (drainage and safety)
Ducted unit = condensation in air conditioning mode. Therefore:
-
correct drain slope
-
watertight fittings
-
reduction of the risk of overflow
-
prevention of odors and moisture return
It's an "invisible" detail, but it's one of the most critical points for preserving ceilings, gypsum, floors... and peace of mind.
3) Vibration and noise reduction
Even a good machine can become noisy if it's poorly integrated. We pay particular attention to:
-
anti-vibration (suitable mounts)
-
the fixings and contact points
-
aligning the conduit sections (avoiding stresses)
-
the quality of the sealing of the joints
The result: a more “subtle” comfort, particularly appreciated in stacked apartments (very common in Rosemont).
4) Sealing and performance of the ducts
In a ducted system, performance depends not only on the machine, but also on the distribution .
We secure:
-
sealing the fittings (to limit losses)
-
isolation of sensitive sections (depending on location)
-
the consistency of airflow to important areas (bedrooms, living area, office)
The goal: to avoid rooms that are “too hot” and others that are “too cold”, a classic problem when a network is improvised.
Why this installation is particularly well-suited to Rosemont–La Petite-Patrie
In this sector, we often see:
-
gradual renovations (one room, one floor, then the next)
-
dwellings with partitions and ceilings modified over time
-
more specific comfort needs (teleworking, children's bedrooms, double rooms)
Ducted air conditioning then becomes a logical choice for gaining discretion while significantly improving thermal stability. And with a brand like Gree , the aim is a good balance between performance, reliability, and comfort .
What owners notice after commissioning
After a properly executed ducted installation, the difference is quickly noticeable:
-
More uniform temperature (less variation from one room to another)
-
More consistent comfort during rapid weather changes (very frequent in Montreal)
-
Less unpleasant “direct blast”
-
A cleaner interior: discreet grilles , hidden machine
And most importantly: when the system is correctly sized and installed, unnecessary cycles are reduced, which improves comfort and helps to maintain more controlled consumption.
Common mistakes that AirGreen avoids (and that cost a lot)
In ducted systems projects, certain mistakes are repeated far too often:
-
Underestimating the importance of the pipes (leaks, unbalanced flow rates)
-
Install the unit in a space without realistic maintenance access
-
Neglecting drainage management (condensation = potential damage)
-
Forgetting the impact of vibrations in a residential structure
-
Improvising the air intake (poorly placed return = inconsistent comfort)
Our approach: we treat the installation as a complete whole — unit, ducts, drainage, access, sealing — and not as a simple “equipment replacement”.
Our AirGreen approach: clean, sustainable, and designed for maintenance
With every Gree ducted installation, we aim for three things:
-
Real comfort (not just a spec sheet)
-
Careful integration (discretion + access)
-
Long-term reliability (drainage, waterproofing, installation quality)
This is particularly important in Montreal, where a system must be ready to withstand: summer humidity, dry cold, thaws, and long periods of heating.
