A neat installation by AirGreen in the heart of downtown Montreal
In a light-filled condo located in Ville-Marie , our AirGreen team recently installed a Sharp ZU1 wall-mounted heat pump , a model known for its quiet performance and its ability to provide constant comfort, even in Quebec's extreme weather conditions.
A thoughtful choice for an urban space
Downtown condos often present unique challenges: tight spaces, load-bearing concrete walls, noise constraints, and a sleek interior design. For this project, our client wanted an energy-efficient and discreet solution . The Sharp ZU1 was a natural choice thanks to:
-
Its high energy efficiency (R-32) , reducing consumption while reducing environmental impact;
-
Its compactness is ideal for small surfaces;
-
Its reliable heating capacity down to -25°C , essential for Montreal winters;
-
Its sound discretion , both inside and outside.
Technical details and installation configuration
The indoor unit was installed on a south-facing wall , benefiting from excellent air circulation. The refrigerant connection , carefully sheathed in discreet white capping , follows a short, direct route to the outside, optimizing performance and minimizing heat loss.
The installation is gravity -fed, without a condensate pump, allowing natural drainage of condensate to the outside. The outdoor unit, fixed on anti-vibration wall brackets , ensures exemplary stability, even during periods of freezing and thawing.
A quick and clean installation
Our RBQ and CCQ certified technicians completed this installation in a single day , in full compliance with electrical standards and Sharp manufacturer's guidelines. Before commissioning, each component was checked:
-
Nitrogen leak test;
-
Complete vacuum draw of the circuit;
-
Checking pressures and calibrating blowing temperature;
-
Rapid customer training in use and maintenance.
Everyday performance and comfort
Since its commissioning, the Sharp ZU1 heat pump has ensured consistent, even comfort throughout the apartment, while reducing heating costs by approximately 30% compared to traditional electric heating. In summer, the air conditioning mode maintains a cool, pleasant temperature, without drafts.
Why the Sharp ZU1 Series Stands Out
The Sharp ZU1 is designed for the North American market and is suited to Quebec's harsh winters. Its strengths include:
-
R-32 refrigerant, more ecological and efficient;
-
Fine modulation inverter technology;
-
Operation down to -25°C in heating mode ;
-
Self-cleaning mode of the indoor coil;
-
Intuitive remote control with energy saving mode.
