For this project in Rosemont–La Petite-Patrie , we assisted a condo owner who wanted to modernize their air conditioning system while adding a truly efficient heating capacity for winter. Our recommendation: the installation of aSharp wall-mounted heat pump , a compact, efficient solution perfectly suited to Montreal condominiums.
A bright condo with large windows… and comfort challenges
The accommodation is located in a residential building typical of the area:
-
several floors,
-
large patio door opening onto a balcony,
-
unobstructed view of the trees and rooftops of Rosemont.
This configuration provides a great deal of natural light, but presents two major challenges:
-
Significant solar gain in summer : heat accumulates quickly, especially in the afternoon.
-
Heat loss in winter : even with high-performance windows, the proximity of the glass can create a feeling of cold.
The client's objective was therefore clear:
benefit from a 4-season system capable of efficiently cooling in summer, comfortably heating in winter and maintaining a stable temperature throughout the living space.
The choice: a Sharp wall-mounted heat pump
We proposed a Sharp Eco Inverter wall-mounted heat pump , from the Sharp ZU1 (R-32) model family, in a single-zone configuration, dedicated to the main open area (living room, dining room, kitchen).
This choice is necessary for several reasons:
-
High energy efficiency thanks to Sharp inverter technology, which continuously modulates the compressor power according to actual needs.
-
Very quiet operation , both inside and outside, a crucial point in a condominium.
-
Reliable performance in Quebec winters , with excellent heating capacity in cold weather.
-
Clean design , which integrates easily into an existing decor without having to redo everything.
The capacity (in BTU) was carefully sized according to:
-
of the surface area of the open area,
-
the orientation of the windows,
-
of the building's insulation level.
Interior installation details
The photo shows the Sharp wall-mounted head installed just above the large patio door:
-
High position, near the ceiling
-
This position allows for better air circulation throughout the room; fresh or warm air is projected towards the center of the condo, then naturally descends.
-
It frees up wall space and does not interfere with furniture or curtains.
-
-
Installation above the window
-
Placing the heat pump above the patio door allows you to directly treat the area most sensitive to temperature variations: the large glazed surface.
-
This reduces heat pockets in summer and the feeling of cold near windows in winter.
-
-
Discreet integration into the decor
-
The chosen Sharp model has a simple and modern finish that blends well with the existing wall covering.
-
The transition line with the ceiling and the finishing box above ensure a clean finish, without visible cables or pipes.
-
-
Refrigerant line and drain management
-
The refrigeration lines (insulated copper) and the condensate drain are carefully concealed in a finishing cover running along the ceiling to the exit to the balcony.
-
The drain is installed with the appropriate slope to ensure gravity drainage of condensation water, avoiding any risk of dripping or infiltration.
-
The Sharp outdoor unit: efficiency and discretion
From the balcony, you can see the Sharp outdoor unit positioned on a stable stand:
-
Elevated installation to promote air circulation and protect the unit from the accumulation of snow and ice.
-
Adequate distance from the facade to comply with the clearances recommended by Sharp and ensure optimal performance.
-
Thoughtful orientation to limit noise transmission to immediate neighbors and into the condo.
The indoor unit + outdoor unit together form a Sharp wall-mounted heat pump perfectly suited to the urban environment of Rosemont–La Petite-Patrie.
Four-season comfort for the customer
Since its installation, the new Sharp wall-mounted heat pump has offered the homeowner several tangible benefits:
In summer
-
Rapid cooling of the main room, even during heat waves.
-
Precise temperature control thanks to inverter mode which avoids excessively frequent on/off cycles.
-
Effective dehumidification is essential during periods of hot and humid weather in Montreal.
During the off-season
-
It is possible to use the heating mode to delay the activation of the central heating or electric baseboard heaters.
-
Stable and pleasant temperature in spring and autumn, with very reasonable electricity consumption.
In winter
-
Significant contribution to heating the condo, relieving the existing electrical systems.
-
More even heat distribution, particularly appreciated near large windows.
-
It is possible to use lower instructions at the baseboard level while maintaining the same level of comfort.
The result: enhanced comfort and better-controlled energy bills .
Compliance with condominium standards and building code
In a co-owned property, each installation must meet a set of constraints:
-
Building regulations : position of the outdoor unit, noise pollution, visual impact on the facade.
-
Building Code and Electrical Code :
-
dedicated power supply with appropriate circuit breaker;
-
compliant wiring;
-
adequate protections.
-
During this project in Rosemont–La Petite-Patrie, we have:
-
The feasibility was validated with the condominium association;
-
Strictly adhered to the clearances, heights and fixings required by Sharp;
-
Documented the installation (photos, serial numbers, nameplate) to facilitate any future warranty or subsidy claim, if applicable.
