In this charming Outremont home, surrounded by greenery and large, mature trees, the owners wanted to replace their aging air conditioning system with a modern, quiet, and above all, efficient heating solution for Montreal winters. Our AirGreen team recommended the installation of aSharp wall-mounted heat pump , model Sharp ZHU1 18,000 BTU , perfectly suited to a single-family home with living areas on the ground floor and bedrooms upstairs.
A green… and demanding residential environment
The house, typical of Outremont, is covered in pale stucco with large wooden windows overlooking a well-landscaped garden. This verdant setting offers two important features for a heat pump system:
-
Heavy vegetation near the exterior walls, which can impair ventilation if the unit is poorly positioned;
-
A facade exposed to climatic variations : sun in summer, snow and cold winds in winter.
The challenge was therefore to install the outdoor unit discreetly , efficiently and sustainably , while preserving the aesthetics of the house and the health of the garden plants.
The chosen solution: Sharp ZHU1 18,000 BTU wall-mounted heat pump
We directed the owners towards a Sharp ZHU1 18,000 BTU wall-mounted heat pump , a new generation unit operating on R-32 refrigerant , known for its excellent energy efficiency and reduced environmental impact.
This Sharp model offers:
-
A power of 18,000 BTU , ideal for covering a main living area (living room, dining room, open kitchen) as well as part of the upper floor;
-
Four-season operation , capable of efficiently heating during the coldest weather while providing comfortable air conditioning during heat waves;
-
Inverter technology that continuously adjusts power, reducing temperature variations and energy consumption;
-
A reduced noise level , appreciated both inside the house and in the garden.
Details of the outdoor installation: performance and discretion
The photo shows the Sharp outdoor unit securely fixed to wall brackets on the plastered wall, slightly raised above the floor. This positioning is not accidental: it meets several technical and practical requirements.
1. Clearance from the ground and snow
By placing it at an appropriate height, we protect the unit:
-
Accumulations of snow in winter;
-
Plant debris and stagnant moisture on the ground;
-
Risk of accidental impacts (lawnmower, garden tools, etc.).
This helps to extend the life of the compressor and ensures good air circulation around the device.
2. Management of refrigeration and electrical connections
The refrigerant lines and power cable are neatly enclosed in a vertical and horizontal white conduit , perfectly aligned with the facade's style. This enclosure:
-
Protects the tubing from weathering and UV rays;
-
Improves the aesthetics of the facade by avoiding visible cables;
-
Facilitates potential service interventions.
The connection is made close to the electricity meter , which simplifies the installation of the dedicated line and the external disconnect device, in accordance with Quebec electrical standards.
3. Vegetation Management
The unit is integrated into the existing vegetation, but with calculated clearance at the front and sides to allow air to circulate freely. We advised the owners:
-
To regularly prune the shrubs and plants around the heat pump;
-
Maintain a free space of at least 30 to 60 cm all around the device;
-
Clear the area before service or cleaning periods.
Thus, the garden retains its natural charm, while ensuring maximum performance from the Sharp heat pump.
Indoor comfort: a warm house in winter, cool in summer
Inside, the Sharp wall-mounted heat pump primarily serves:
-
The living room and dining room on the ground floor, often combined in an open area;
-
Part of the upstairs corridor , facilitating the transfer of heat or coolness to the bedrooms.
The benefits for the occupants:
-
Gentle and even warmth in winter, without dry air and without sudden fluctuations;
-
Rapid air conditioning on hot days, even in direct sunlight;
-
Better humidity control , which is very welcome in a house surrounded by vegetation;
-
A significant reduction in electricity bills , especially for those who previously used inefficient electric baseboard heaters or portable devices.
An installation that meets standards and is designed for longevity
At AirGreen, we place particular importance on:
-
Regarding electrical compliance (dedicated line, circuit breaker rating, outdoor disconnect box);
-
Sizing the power according to the surface area and insulation of the house;
-
In compliance with the recommendations of the manufacturer Sharp (clearances, fixings, condensate drainage);
-
The quality of the wall supports and anchors in the masonry or plaster.
Every detail counts to ensure that the Sharp ZHU1 wall-mounted heat pump operates reliably for many years, with minimal maintenance (filter cleaning, annual inspection, clearance checks).
