In Brossard, on Montreal's South Shore, a homeowner wanted to upgrade his heating and air conditioning system. His goal: to reduce his energy bill while increasing comfort, both summer and winter.
We suggested the installation of a Gree wall-mounted heat pump with Inverter technology , an ideal solution for a suburban residence with a terrace and backyard.
Context of the residential project in Brossard
The house is typical of Brossard: a front yard entrance, a raised back patio, a concrete slab, and paved landscaping. The client was still using more energy-intensive heating systems and a portable air conditioner to cool a few rooms, without any real precise temperature control.
The main challenges:
-
Unequal comfort between the ground floor and the upper floor;
-
Overheating in summer in rooms facing the sun;
-
High heating costs in winter, despite the house being properly insulated.
Installing a Gree wall-mounted heat pump made it possible to address these challenges while preparing the house for the harsh winters of Greater Montreal.
Choosing a Gree Inverter wall-mounted heat pump
We recommended a Gree single-zone wall-mounted heat pump with inverter technology . This residential line from Gree is designed to offer:
-
High energy efficiency : the Inverter compressor continuously adapts its power according to the actual heating or cooling demand, which reduces electricity consumption.
-
Excellent performance in winter : the unit continues to heat efficiently even when the mercury plunges below −20 °C, a well-known reality on the South Shore.
-
Quiet operation : both for the indoor unit and the outdoor unit, which is appreciated in a quiet residential area of Brossard.
-
High reliability : Gree is one of the brands we install most often at AirGreen, especially for wall-mounted heat pump projects.
Inside, the Gree wall head was installed in the main living area to serve the living room, kitchen and part of the upstairs, creating centralized comfort for the whole family.
Details of the outdoor installation under the terrace
The photo clearly shows the Gree outdoor unit installed under a concrete slab, sheltered by a balcony or terrace. This location choice is strategic for the Quebec climate.
Weather protection
By positioning the condenser under the terrace structure , we offer:
-
a natural protection against snow and ice ;
-
a reduction in ice buildup on top of the unit;
-
better protection against driving rain and direct sunlight , which helps to extend the life of the device.
This configuration remains in line with the manufacturers' recommendations: the unit has enough space around it to ensure good air circulation at the front and sides.
Elevated and stable support
The Gree heat pump is installed on a raised metal stand , itself placed on stable concrete slabs/blocks. This approach offers several advantages:
-
The unit is raised above ground level , which protects it from accumulated snow and meltwater in the spring.
-
The support ensures good mechanical stability , limiting vibrations and noise transmitted to the building.
-
The whole thing remains easily accessible for maintenance , without direct contact with the soil or garden plants.
Under and around the unit, we leveled the ground with rock and gravel to promote drainage and prevent puddles that could freeze in winter.
Management of connections, drainage and electricity
To the right of the condenser, the routing of the insulated refrigerant lines and electrical wiring , protected by a sheath, is visible. We have:
-
respected the bending radii of the refrigerant pipes to preserve the efficiency of the system;
-
properly insulate the lines to limit heat loss;
-
adequate drainage of condensate is provided, often connected to a gravel area or an existing drain;
-
installed and connected the electrical supply according to the Quebec electrical code , with a dedicated circuit breaker and disconnect switch near the unit.
This attention to detail ensures reliable, safe and efficient long-term operation.
Interior integration: comfort and discretion
Although the provided photo primarily shows the outdoor unit, the heart of the customer experience lies inside. In this Brossard home, the discreet, white Gree wall-mounted unit was installed to:
-
to effectively circulate the air in the main living areas;
-
avoid direct air currents on the occupants;
-
to blend harmoniously into the existing decor.
We drilled cleanly through the wall, using a sealed and insulated hole to prevent air or moisture infiltration. The connections are concealed as much as possible for a neat and professional finish.
Results for the customer: comfort, savings and peace of mind
Since installing his Gree wall-mounted heat pump, the homeowner has benefited from several tangible advantages:
-
Four-season comfort : efficient air conditioning in summer and efficient heating in winter, with a stable temperature throughout the service area.
-
Energy bill reduction : Inverter technology allows for savings compared to traditional electric heating and portable air conditioners.
-
Quiet operation : both inside and in the backyard, the noise level is controlled, which is appreciated by the family… and the neighbors.
-
Simple and precise control : the Gree remote control allows you to adjust the temperature, fan speed, operating mode and time programs.
-
Easy maintenance : access to the outdoor unit is unobstructed despite its position under the terrace, simplifying maintenance visits and seasonal inspections.
