A neat and discreet interior installation carried out by AirGreen
In a bright apartment in the Villeray–Saint-Michel–Parc-Extension neighborhood, our AirGreen team installed a Sharp ZU1 wall-mounted heat pump , a solution renowned for its high energy efficiency and reliability in cold climates. This project perfectly illustrates our meticulous approach to residential HVAC installation : performance, cleanliness, and aesthetic integration.
Choosing the Sharp ZU1 model: performance and comfort in an urban environment
The Sharp ZU1 , equipped with Plasmacluster Ion technology, purifies the air while providing stable heating down to -25 °C . This compact model blends harmoniously into modern living spaces, while providing remarkable operating silence .
For this typical Montreal accommodation, the client's criteria were clear:
-
An effective year-round solution to replace an old, noisy air conditioner.
-
An elegant wall installation , without visible conduit.
-
Minimal maintenance , with easy access for cleaning filters.
The Sharp ZU1 was a natural choice thanks to its superior energy efficiency and discreet design .
A clean and optimized installation
In this project, the indoor head was installed on a white load-bearing wall near the living room. The installation was carried out with millimeter precision to ensure even distribution of airflow throughout the main room.
The refrigeration connections and the condensate drain are grouped in a white capping running along the wall to the exterior outlet, ensuring a clean and uniform finish . This technical choice allows:
-
Perfect visual discretion .
-
Easy access in case of maintenance.
-
Better protection of lines against shocks or dust.
The installation also complies with RBQ and Hydro-Québec electrical standards, with a dedicated circuit and an independent circuit breaker .
The gravity condensate drain ensures smooth evacuation, without a pump, which reduces noise and maintenance requirements.
AirGreen know-how: precision, safety and cleanliness
Each AirGreen installation follows a rigorous protocol:
-
Checking the optimal location according to the layout of the accommodation.
-
Waterproof drilling with vapor barrier sleeve and insulating mastic.
-
Installation of capping and sealing of fixings to prevent any air infiltration.
-
Nitrogen pressure test and deep vacuum before commissioning.
-
Airflow and temperature differential control for immediate comfort.
Our technicians always leave a clean, functional and tested site: each step is documented and validated before the team leaves.
An aesthetic and functional result
The Sharp ZU1 head blends elegantly into the interior environment: its slim profile follows the ceiling line and its automatic horizontal blowing guarantees uniform comfort throughout the living room.
The customer now benefits from:
-
Rapid heating from the first cold spells of autumn.
-
Gentle and quiet air conditioning during the summer.
-
Healthier air , thanks to Plasmacluster Ion technology which neutralizes allergens and fine particles.
An ideal solution for Montreal apartments
Apartment buildings like those in Villeray–Saint-Michel–Parc-Extension often present technical challenges: concrete ceilings, tight spaces, and the inability to add ducts. It is precisely in this type of configuration that the wall-mounted heat pump excels.
Thanks to the compactness of the Sharp ZU1 and our expertise in discreet conduit passage , we were able to deliver a silent, efficient and aesthetic installation, perfectly suited to urban life.
Maintenance and durability
To maintain optimal performance, AirGreen recommends:
-
Cleaning the internal filters every two months.
-
A complete annual inspection including checking the drain, refrigerant gas and compressor efficiency.
-
Seasonal maintenance of the outdoor unit to ensure smooth operation even in winter.
Our preventative maintenance contracts provide peace of mind and extend the life of your device.
