A meticulous residential project on the North Shore
At AirGreen , every HVAC system installation is designed to provide our customers with lasting comfort, optimal energy performance and impeccable aesthetic integration. This project in Rosemère , on Montreal's North Shore , perfectly illustrates our approach.
The client, the owner of a semi-detached house, wanted to modernize his heating and cooling system by replacing several independent wall-mounted air conditioners with a Trane MultiZone heat pump capable of powering several indoor units with a single outdoor compressor.
Needs analysis and system selection
Our technicians first carried out a complete energy assessment of the building to determine the ideal power and the most appropriate type of installation.
The main criteria were:
-
Reduce electricity consumption.
-
Uniform the temperature in all rooms.
-
Free up outdoor space by limiting the number of compressors.
The choice fell on a Trane 24,000 BTU MultiZone system using R-410A refrigerant , known for its efficiency and reliability. This model allows the connection of up to four independent indoor units, perfect for a multi-story house.
Installation: precision and space optimization
The main challenge of this project was the limited space between the house and the side fence , leaving barely any room for the technician to pass through. This constraint required careful planning.
Our experts have:
-
Securely mounts the Trane outdoor compressor to a reinforced wall bracket, ensuring stability even in freezing and thawing conditions.
-
Installed a system of insulated and carefully sheathed refrigeration pipes , protected by a wall cover in a color matching the brick.
-
Completed the connection of the four independent circuits (one per indoor unit) with perfectly calibrated connections.
-
Performed a complete vacuum draw down to 500 microns to eliminate all traces of moisture and ensure the longevity of the system.
-
Charged the refrigerant according to the manufacturer's exact specifications.
Final pressure tests confirmed a perfect seal.
Commissioning and calibration
Once the mechanical installation was complete, we commissioned each indoor unit to calibrate the airflow and set temperature.
Results :
-
Remarkable thermal stability in all rooms.
-
Reduced noise level , even in heating mode.
-
Increased responsiveness thanks to Trane inverter modulation.
The customer was impressed by the rapid temperature rise and the simplicity of the integrated Wi-Fi central control.
Observed benefits and customer satisfaction
From the first week, the client noted:
-
A significant reduction in the electricity bill .
-
Better overall comfort , especially in upstairs bedrooms.
-
Discreet integration of the external compressor despite limited space.
We also recommended annual preventative maintenance including cleaning the coils, checking pressures and calibrating the temperature probes.
