For this project, we visited a single-family home in Boucherville , on Montreal's South Shore. The homeowners wanted to replace their portable air conditioner with a complete heating and cooling solution that was quiet and reliable in winter. We suggested installing a Gree wall-mounted heat pump , perfectly suited to this type of residence with a grassy side yard and a wooden fence.
A clear need: more comfort, less consumption
The house already benefits from good insulation, but the temperature differences between summer and winter remained significant:
-
Summers are getting hotter and hotter, with persistent heat in rooms on the sunny side.
-
Harsh Quebec winters, where electric baseboard heaters consumed a lot of energy to maintain acceptable comfort.
The owners had a twofold objective:
-
Improve comfort in the main living areas.
-
Reduce the electricity bill without compromising system reliability in the middle of January.
The chosen solution: a Gree single-zone wall-mounted heat pump , approximately 12,000 BTU, ideal for covering a semi-open-plan main floor.
Why a Gree wall-mounted heat pump?
Gree wall-mounted heat pumps are known for:
-
Their Inverter technology , which modulates the power rather than operating in on or off mode;
-
Their excellent energy efficiency , both in air conditioning and heating;
-
Their quiet operation is important in a quiet residential area like Boucherville;
-
Their ability to provide efficient heating in sub-zero temperatures is a necessity on the South Shore.
By replacing or supplementing electric baseboard heaters, this Gree heat pump allows occupants to enjoy a stable and pleasant temperature while saving on their Hydro-Québec bill.
Side courtyard layout: constraints and considerations
The Gree outdoor unit was installed in the side yard , along a stucco wall overlooking a strip of lawn. Several factors influenced our choice of location:
-
The presence of the electricity meter nearby facilitates the supply and installation of the external disconnect switch;
-
The neighboring wooden fence requires compliance with the recommended clearances for air circulation and maintenance;
-
The natural slope of the land and the risk of rainwater or melted snow accumulating near the foundation.
We therefore chose a location that respects both the technical constraints and the comfort of the occupants: the unit is discreet from the street, without hindering access to the gate or encroaching on circulation spaces.
Installation details visible in the photo
Several key elements of our AirGreen expertise are visible in the photo:
-
Gree outdoor unit on wall bracket
The heat pump is securely mounted on galvanized steel brackets anchored to the foundation. This is an elevated installation:-
Keeps the device at the correct height relative to the ground.
-
Protects against snow, ice and moisture,
-
Reduces the transmission of vibrations to the building.
-
-
Proper management of refrigeration connections
The refrigerant lines, condensate drain, and communication cabling are protected in a vertical white trunking leading to the house entrance. This approach:-
Protects connections against shocks and weathering;
-
Improves the aesthetics of the wall;
-
Facilitates intervention during a future interview.
-
-
Electrical connection compliant
Next to the meter, you can see the outdoor electrical disconnect switch , which meets Hydro-Québec and Electrical Code requirements. It allows you to quickly shut off the power to the Gree heat pump during work or maintenance. -
Preservation of the land and foundation
Underneath the unit, we stabilized the ground with stones and cleaned the base of the wall in order to:-
Promote water drainage;
-
Avoid accumulations of compacted snow in contact with the foundation;
-
Keep the area accessible for service.
-
Performance and comfort in all seasons in Boucherville
With this Gree wall-mounted heat pump , homeowners now benefit from:
-
Effective air conditioning during periods of summer heat, with cool air diffused silently inside;
-
High-performance, high-efficiency heating during the winter, reducing reliance on electric baseboard heaters;
-
From an Intelligent Inverter device capable of precisely adjusting its power to maintain a stable temperature, without large differences between hot and cold.
The whole thing is done in remarkable silence both inside and outside, which is appreciated by both the occupants and the close neighbors.
A discreet, aesthetically pleasing and durable installation
An important point for this Boucherville residence was to preserve the neat character of the side courtyard:
-
The Gree unit is well aligned with the wall , at a convenient height for maintenance, while remaining quite discreet.
-
The white gutter visually blends into the grey plaster, giving an impression of a clean and professional finish.
-
The passage to the door and the wooden gate remains clear; the heat pump does not obstruct traffic or the opening of the gate.
This attention to aesthetics is part of AirGreen's DNA: a heat pump system must be efficient, but also well integrated into your outdoor environment.
