A neat wall installation project on a brick residence
At AirGreen , we recently completed a Gree MultiZone heat pump installation in a charming single-family home in Rosemère , on Montreal's North Shore. This project perfectly illustrates our attention to detail and our technical approach adapted to the traditional red brick residences typical of the region.
Context and objectives of the project
The homeowners were looking for an efficient heating and cooling solution for two floors of their home without the need for ductwork. After a comprehensive assessment, we recommended a Gree MultiZone heat pump —a powerful, quiet system ideal for homes with multiple comfort zones.
Choosing a MultiZone system allowed them to independently control the temperature of the main rooms, ensuring optimal comfort while reducing energy consumption.
Building analysis and preparation
Before any installation, our team proceeded to:
-
A detailed inspection of the exterior wall , to determine the best location for the outdoor units.
-
A study of the passage of refrigerant pipes and electrical cables , taking into account aesthetics and the brick structure.
-
A check of the available electrical load at the main panel to avoid any overload.
The northwest-facing wall provided excellent free air circulation and sufficient distance from the ground , ideal conditions to ensure long-lasting compressor performance.
Technical installation: precision and durability
Our technicians mounted two Gree outdoor units on sturdy galvanized wall brackets , capable of supporting the weight and reducing vibrations. These raised brackets offer several advantages:
-
Protection against snow and ice in winter.
-
Better heat dissipation during hot days.
-
Easy access for future maintenance.
The insulated copper refrigeration pipes were carefully grouped in a vertical black sleeve, ensuring a clean and professional finish while protecting the pipes from the elements.
Inside, each zone received a discreet and quiet high-efficiency Gree wall-mounted unit , connected to a single outdoor condenser.
Technical details of the installed system
-
Type: Gree MultiZone wall-mounted heat pump
-
Number of zones: 2
-
Total capacity: 24,000 BTU
-
Refrigerant gas: R-32 (low environmental impact)
-
Energy efficiency: SEER 22 / HSPF 11
-
Voltage: 208/230V
-
Sound level: 53 dB outside – 23 dB inside
This model stands out for its Inverter technology , which automatically adjusts the compressor power according to actual demand, thus reducing start-up cycles and electricity consumption.
Aesthetic finish and conformity
One of the most appreciated aspects of this installation was the visual discretion of the assembly . Due to the red brick facade, we chose neutral-colored ducts and supports , ensuring perfect integration into the house's environment.
Every electrical and refrigerant connection was checked and pressure tested , then sealed according to CSA and RBQ standards. A nitrogen leak test confirmed the absence of leaks before commissioning.
Commissioning and results
Upon final startup, both units operated without excessive vibration or abnormal noise. The programmed temperatures in each zone were reached quickly, demonstrating the effectiveness of the Gree system.
The owner particularly noted the stable comfort and near-silent operation of the interior equipment. In addition, thanks to Gree's intelligent defrosting technology, winter performance remains stable down to -25°C .
Recommendations and maintenance
To ensure the longevity of the system, we advised the customer to:
-
Clean the internal filters every two months.
-
Schedule a complete annual maintenance with AirGreen (pressure check, coil cleaning and electrical check).
-
Keep outdoor units clear of snow and vegetation for optimal airflow.
These simple actions extend the life of the compressor and ensure maximum performance in all seasons.
