In Brossard, on Montreal's South Shore, a family owning a single-family home wanted to modernize their heating and air conditioning system. Their goal: to be comfortable during both summer heat waves and the bitter cold of winter, while reducing their electricity bill.
We recommended the installation of a Gree Inverter wall-mounted heat pump with R32 , a high-performance and discreet residential system, perfectly suited to the climatic realities of Greater Montreal.
A typical South Shore residential project
The house is typical of Brossard's residential neighborhoods: pale vinyl siding, a brick corner wall, a small lawn, and a nearby driveway. The client had limited space on the side of the house, which necessitated a compact, unobstructed, and safe outdoor installation.
Before starting the work, we have:
-
analyzed the orientation of the facade and the prevailing winds;
-
checked the necessary clearances around the future condenser;
-
planned the routing of the refrigeration lines and the condensation drain in a clean and discreet manner.
The goal was to integrate the Gree heat pump harmoniously, without harming either the aesthetics of the house or daily movement around the yard.
Why a Gree R32 wall-mounted heat pump?
The Gree wall-mounted range with Inverter technology uses R32 refrigerant, category A2L , as indicated on the outdoor unit's label. This choice offers several tangible advantages for a Brossard homeowner:
-
High energy efficiency : the inverter compressor modulates continuously, which helps to avoid energy-intensive on/off cycles.
-
Cold weather performance : Gree R32 models maintain very good heating capacity even in temperatures well below freezing, ideal for Quebec winters.
-
Reduced environmental impact : R32 has a lower global warming potential (GWP) than the old R410A, making it part of a more responsible approach.
-
Acoustic comfort : the fan and compressor are housed in a well-insulated casing, significantly reducing noise both outside and inside.
In this project, we configured the system as a single-zone wall-mounted heat pump , dedicated to the main living area of the house (open-plan living room, dining room and kitchen).
Details of the outdoor unit installation
The photo shows the Gree outdoor unit installed against the side wall of the house. Several technical choices were made to guarantee reliability and longevity:
-
Wall-mounted : The condenser is securely fixed to metal brackets anchored to the wall. This raises it off the ground to protect it from the accumulation of snow, ice, and debris.
-
Clearance around the fan : the area in front of the grille is clear to ensure optimal air circulation, essential for the proper functioning of the heat pump.
-
Condensate management : a PVC drainage pipe runs down under the unit, allowing for the clean removal of summer condensation water.
-
Protected refrigeration connections : refrigerant lines and wiring are grouped, protected and routed to the house in an orderly manner, which facilitates future maintenance and avoids direct exposure to the elements.
-
Intelligent positioning : we have placed the unit away from falling ice from the roof and at the edge of the passage area, in order to limit the risk of impact and vibration.
As with all our installations, we checked the level of the supports, carried out a rigorous vacuuming, checked for leaks and validated the operating pressures before commissioning.
Interior comfort and performance in all seasons
Inside, the Gree wall-mounted unit diffuses air gently and evenly, without harsh drafts. Thanks to the precise modulation of Inverter technology:
-
In summer , the house stays cool even on hot and humid days, thanks to effective dehumidification;
-
In mid-season , the heat pump ensures stable comfort while consuming very little energy;
-
In winter , the system takes over a large part of the heating, reducing the use of electric baseboard heaters and therefore the Hydro-Québec bill.
The customer has already noticed that the temperature is much more constant from room to room, and that the feeling of heaviness and summer humidity has disappeared.
Results for the Brossard family
Since the Gree wall-mounted heat pump was installed, the homeowners have benefited from:
-
four-season comfort in the main rooms;
-
a good reduction in the electricity bill , particularly in winter;
-
a quieter house , with the wall-mounted head operating at very low speed most of the time;
-
modern and environmentally friendly equipment , thanks to the R32 refrigerant and high energy efficiency.
The discreet installation of the outdoor unit on the side of the house also helps to preserve the aesthetics of the front facade and the backyard.
