On this project in the Plateau-Mont-Royal borough , our AirGreen team installed a Gree FreeMatch MultiZone heat pump with an outdoor unit positioned on a rooftop terrace . This type of environment (brick wall, metal railings, roofing membrane) is very typical of Montreal residential buildings and requires rigorous execution to guarantee stability, quiet operation, and durability .
A logical choice for Montreal's plexes: MultiZone
The Gree FreeMatch is an ideal solution when a dwelling has several spaces to serve (open area + bedrooms, floor + mezzanine, etc.) and you want to maintain maximum control room by room.
Specifically, we are talking about a multi-zone heat pump (multi-zone mini-split) :
-
an outdoor unit (condenser)
-
capable of powering multiple indoor units (depending on the chosen configuration)
When the exact model is not legible on the label, we remain consistent with the range: a Gree FreeMatch Multi R32 (2 to 5 zone configuration), very common in residential areas in Greater Montreal.
Prominent installation details observed in the photo
1) Outdoor unit on an elevated support (roof terrace)
The unit is installed on an elevated metal structure , which is excellent practice on a rooftop:
-
protects the membrane by preventing direct contact
-
improves drainage (water, slush) under the device
-
limits the accumulation of leaves and debris around the interchange
-
facilitates seasonal maintenance and winter clearing
We also pay particular attention to load distribution , because on a roof terrace, it is necessary to avoid any excessive pressure point on the roof.
2) Proper management of conduits and wiring
The finishing elements of the construction site are clearly visible: pipes, cables, tools, and fasteners. In a densely populated area like the Plateau, the quality of the delivery (and its final appearance) makes all the difference.
-
logical and safe route
-
solid fixings to the brick (appropriate anchoring)
-
protection of sections exposed to UV and weathering
-
maintaining sufficient clearance for service
3) Noise and vibration reduction
In urban environments, comfort doesn't end inside the home: it's also important to respect the neighbors. For this type of installation, AirGreen systematically applies vibration control measures (depending on the substrate and structure) to:
-
reduce transmission to the building
-
avoid resonances on the structure
-
maintain quiet operation, even when heating
4) Service areas and air circulation
The outdoor unit is positioned to maintain clearance around the fan and service panels. This is essential for:
-
preserve efficiency (proper ventilation of the device)
-
to facilitate maintenance and repairs
-
avoid hot/cold air recirculation which reduces efficiency
Commissioning: our AirGreen method
A high-performing multi-zone installation relies as much on the equipment as on the commissioning. For this type of project, we notably carry out:
-
leak tests and fitting checks
-
vacuuming according to best practices
-
Electrical inspection and safety measures
-
validation of pressures/temperatures during operation
-
calibration of heating/cooling modes for the actual comfort of the occupants
Why this installation is particularly well-suited to Plateau-Mont-Royal
The Plateau often combines: brick buildings, fragmented spaces, outdoor location constraints, close neighbors, and the need for winter/summer comfort. A well-installed Gree FreeMatch allows you to achieve:
-
effective air conditioning during heat waves
-
efficient heating during Quebec's cold weather
-
A very practical zone-based management system for everyday use
-
a discreet system that is well integrated into the building
Conclusion
This Gree FreeMatch MultiZone heat pump installation in Plateau-Mont-Royal perfectly illustrates the AirGreen approach: a clean, thoughtful and sustainable execution, with an exterior positioning optimized for the roof, performance and tranquility of the occupants.
