A neat and efficient installation for optimal comfort in a modern condo
In the dynamic Saint-Laurent district, known for its modern buildings and its balance between urban life and greenery, our AirGreen team recently installed a Sharp ZU1 wall-mounted heat pump . This model, powered by R-32 refrigerant, stands out for its remarkable energy efficiency and stable operation down to −25 °C , perfectly suited to Quebec winters.
The context: optimizing the comfort of a brick-structured condo
The building in question, a two-story condo with a beige brick façade typical of the area, presented a unique challenge: integrating the outdoor unit aesthetically while meeting efficiency and safety standards. The owner wanted a discreet, quiet solution capable of providing heating and cooling without compromising the façade or disturbing the ground-floor residents.
Model choice: the Sharp ZU1, a high-efficiency wall-mounted heat pump
The Sharp ZU1 has emerged as the ideal choice. This model offers:
-
Adjustable capacity (up to 24,000 BTU depending on needs).
-
Exceptional seasonal efficiency (high SEER).
-
Reduced noise level thanks to its variable speed compressor.
-
Reliable operation at very low temperatures , essential for the Montreal climate.
The device is also eligible for certain subsidies linked to Quebec energy efficiency programs, making it a smart long-term investment.
The particularities of the installation
The installation was carried out on sturdy wall brackets , positioned at an ideal height to avoid any contact with snow and allow optimal ventilation.
The electrical wiring and refrigerant pipes were carefully concealed in beige capping that matched the color of the brick, ensuring a clean and professional visual appearance.
Technical details:
-
Line path : direct wall crossing, with discreet exit under the main window.
-
Duct length : approximately 3.5 meters, minimizing efficiency losses.
-
Gravity drainage of condensates, avoiding the need for a pump.
-
Dedicated electrical box installed in the immediate vicinity for easy maintenance and complies with CSA standards.
Constraint resolution
One of the main challenges was the limited space between windows and the need to ensure sufficient clearance for ventilation of the unit.
Our technicians opted for an installation centered under the largest window, guaranteeing both efficient air flow and visual discretion .
Thanks to precise planning and tailor-made adjustments, we were able to complete the installation in a single day , without disturbing the building occupants.
An aesthetic and lasting result
The Sharp ZU1 unit fits perfectly into the architecture of the condo.
The combination of matching vertical capping , symmetrical positioning and carefully designed height creates an installation that is aesthetic, stable and functional .
In addition, the heat pump helps reduce home energy costs while improving thermal comfort throughout the year.
