A custom installation in a downtown building
Located in the heart of Montreal's Ville-Marie district , a young couple who own a renovated condo contacted us for a project to install a Zephyr wall-mounted heat pump . The goal: to replace an old, noisy, and energy-consuming portable air conditioner with a modern, quiet, and energy-efficient HVAC system capable of ensuring comfort all year round.
In a typical Montreal building with brick walls and limited outdoor space, the main challenge was to integrate the new outdoor unit without altering the building's aesthetics or hindering neighborly access.
Preliminary analysis and preparation of the site
Before any installation, our AirGreen team carried out a complete thermal assessment of the home . This crucial step helps determine the required power and ensures accurate sizing of the system.
The data obtained confirmed that a 12,000 BTU Zephyr model perfectly met the needs of this 900 sq. ft. condo.
Preparation steps:
-
Checking the electrical capacity of the existing panel;
-
Planning the passage of the refrigeration pipe through the brick wall;
-
Selection of a raised wall bracket made of galvanized aluminum to avoid vibrations and facilitate drainage;
-
Coordination with the condominium association to ensure compliance with aesthetic and sound standards .
Installing the Zephyr outdoor unit
The sleek and compact outdoor unit was installed on an AirGreen metal base securely attached to the building's rear façade. Our technicians ensured optimal clearance for airflow and sufficient spacing between the brick and the fan to avoid resonance.
All electrical wiring was housed in a CSA-compliant waterproof conduit , ensuring a secure and discreet installation. We also installed a wall-mounted safety circuit breaker (disconnect box) in close proximity to the unit, compliant with the Canadian Electrical Code.
Interior installation and performance testing
Inside, the Zephyr wall-mounted unit was positioned above the main living area, ensuring even air distribution. The wall opening was carefully insulated to prevent air or moisture infiltration.
Once the power was turned on, our technician carried out a series of tests:
-
Vacuum leak test for 45 minutes at -30 psi;
-
Checking R-410A refrigerant pressure ;
-
Simultaneous heating/air conditioning operation test ;
-
Airflow and sound level measurement (results: 21 dB in low mode, almost inaudible).
A result that lives up to expectations
Within minutes of startup, the client noticed the system's consistent, quiet coolness . The sleek design of the Zephyr indoor unit blended seamlessly with the condo's modern decor, while the recessed outdoor unit remained discreet.
The couple was also impressed by the built-in Wi-Fi connectivity , allowing them to control the temperature remotely via a mobile app – a particularly welcome feature for an urban lifestyle.
