In this Rosemont–La Petite-Patrie apartment, our client's priority was simple: to enjoy year-round comfort without sacrificing the clean aesthetic of her interior. The light, uncluttered walls and the apartment's layout were perfectly suited to the addition of a discreet and efficientSharp wall-mounted heat pump .
Context: a Montreal apartment to optimize
Before our intervention, the apartment was heated primarily by electric baseboard heaters and had no fixed air conditioning. Result:
-
High electricity bills in winter.
-
Stifling heat in summer, especially in the main room.
-
Temperature variations from one room to another.
Our mandate at AirGreen: to install an all-in-one solution for heating, air conditioning and dehumidification, while preserving the minimalist style of the home.
Choosing a Sharp wall-mounted heat pump
We recommended a Sharp ZHU1 12,000 BTU wall-mounted heat pump , a recent model operating with R-32 refrigerant, particularly suitable for apartments in Rosemont–La Petite-Patrie:
-
Heating performance even during the intense cold typical of Montreal winters.
-
Excellent energy efficiency , reducing reliance on electric baseboard heaters.
-
Air conditioning and dehumidification function for more comfortable summers.
-
Simple and elegant design: the white casing blends perfectly into a cream wall, as seen in the photo.
This Sharp model is a good compromise between power, quiet operation and energy saving, ideal for a well-insulated 4½ or 5½.
Integration of the wall unit into the room
In the photo, the Sharp unit is installed high on the wall, just below the ceiling. This positioning was carefully chosen by our team:
-
It allows the blown air to diffuse gently throughout the room , without direct drafts on the sofa or bed depending on the configuration.
-
The height optimizes the mixing of warm air in winter , which avoids cold areas on the floor.
-
The unit remains visually discreet against the plain wall, preserving the clean look of the room.
We also took into account:
-
Adherence to the clearances recommended by Sharp to ensure good air circulation.
-
The distance from wall corners or furniture so as not to disrupt the airflow.
-
Accessibility for filter cleaning and maintenance.
The small marks around the wall bracket, visible at the bottom of the unit, were carefully filled and painted after installation to ensure a clean and professional finish.
Technical installation: efficiency and discretion
Even though only the interior unit appears in the photo, the success of a project like this also depends on everything that is invisible :
-
Passing the refrigeration lines through the wall, choosing the shortest possible route to limit efficiency losses.
-
Installation of a condensation drain with sufficient slope to prevent any water accumulation inside.
-
Installation of the Sharp outdoor compressor at the rear of the building, on anti-vibration supports, to reduce noise perceived by the customer and the neighborhood.
-
Performing a rigorous vacuum test , leak tests and verification of operating parameters before final commissioning.
As always, we provided the customer with all the necessary documents: detailed invoice, installed model, serial number, and useful information for assistance programs or warranties.

Sharp Heat Pump Maintenance and Durability
To preserve the performance and longevity of the heat pump, we advised the client:
-
Clean the filters every 4 to 6 weeks during periods of intensive use.

Avoid obstructing airflow by placing furniture or curtains too close to the unit.
-
To schedule an annual maintenance visit with AirGreen to check the overall operation, drainage, electrical connections and system performance.
