In this project in Ahuntsic-Cartierville , in the north of Montreal, our team replaced an aging air conditioning system with a modernSharp wall-mounted heat pump . Our clients' goal was to enjoy year-round comfort in their brick home, while reducing their energy bills and preserving the aesthetics of the rear facade.
Context: a typical brick house from the north of the island
The property is a single-family home with:
-
rear facade in yellow brick , typical of the residential areas of Ahuntsic-Cartierville;
-
large windows overlooking the backyard , facing full sun for a good part of the day;
-
semi-buried basement , with low windows;
-
wooden terrace with railing, used intensively in the summer.
The owners wanted:
-
To efficiently cool the main living area (living room, dining room and upstairs kitchen);
-
Add a high-performance auxiliary heater to relieve the electric baseboard heaters during periods of extreme cold;
-
Install outdoor equipment discreetly, safely and easily accessible for maintenance , without encroaching on the terrace space.
Choosing a Sharp wall-mounted heat pump
We recommended a Sharp wall-mounted heat pump from the high-efficiency residential range, comparable to a Sharp ZU1 of approximately 12,000 BTU :
-
Inverter technology : the machine continuously modulates its power, which avoids frequent on/off cycles and optimizes electricity consumption.
-
R-32 refrigerant : more efficient and with a lower environmental impact than previous generations using R-410A.
-
Excellent heating performance even at sub-zero temperatures typical of Montreal winters.
-
Quiet operation , both for the indoor unit and the outdoor compressor, so as not to disturb the neighbors or the occupants when they are enjoying the terrace.
The Sharp brand has established itself for its reliability, the quality of its electronic components and the stability of the temperature, both in air conditioning and heating.
Outdoor unit installation details
The Sharp heat pump's outdoor unit was installed at the base of the back wall , between a basement window and the deck. This positioning required careful planning.
Raised support and concrete slab
We opted for:
-
an elevated metal support , securely anchored and equipped with anti-vibration pads;
-
a concrete slab to ensure stability and prevent any subsidence of the ground;
-
a height calculated to remain well above the snow and ice accumulated in winter.
This assembly guarantees:
-
excellent air circulation around the condenser ;
-
a minimization of vibrations transmitted to the structure of the house;
-
simplified access for annual maintenance (cleaning, inspection, testing).
Drainage and snow management
The backyards of Ahuntsic-Cartierville are not spared from snow and freeze/thaw cycles. Therefore, we have:
-
checked the natural slope of the land to prevent defrost water from pooling near the foundation;
-
planned the direction of the flow so that neither the basement window nor the terrace would be splashed;
-
left the necessary space for manual snow removal around the unit in winter.
Passage of connections and conduits
The refrigerant lines, communication cable and power supply are:
-
grouped in exterior channels of a color coordinated with the existing elements;
-
carefully fixed to the wall to avoid friction and premature wear;
-
protected against shocks, humidity and UV rays.
This finishing work allows the installation to remain visually discreet , while offering mechanical protection to the components.
Integration with the indoor unit and air distribution
Inside, the Sharp wall-mounted unit is installed upstairs in the main living area. The single-family home + backyard configuration is perfectly suited to a single-split system .
-
the distance between the wall head and the compressor is optimized, limiting pressure losses in the pipes;
-
the refrigeration network remains relatively short, which improves overall efficiency ;
-
The distribution of fresh or hot air is very homogeneous in the living room, dining room and partially in the corridor.
Owners can therefore:
-
enjoy efficient air conditioning all summer long;
-
benefit from rapid heating when the temperature drops in spring or autumn;
-
maintain a stable temperature without having to constantly adjust the thermostat.
Performance in all seasons in Ahuntsic-Cartierville
With this Sharp wall-mounted heat pump, the house is now ready to face:
-
the heat waves of July and August , where the modulating compressor avoids overconsumption;
-
the extreme cold of January , where the high-performance heating mode allows for a significant reduction in the use of electric baseboard heaters;
-
the more humid periods, during which the dehumidification mode significantly improves comfort.
In practice, customers observe:
-
a reduction in their electricity bill thanks to the advantageous COP of the heat pump;
-
superior acoustic comfort , the machine being much quieter than an old portable or window air conditioner;
-
a more pleasant house to live in, summer and winter, without compromising on the aesthetics of the backyard.
A clean and safe construction site
As with all our installations, we have:
-
protected the work surfaces and cleaned the outdoor area after the work;
-
pressure tests and prolonged vacuum testing were carried out before commissioning;
-
checked the current draw , operating pressures and parameters of the Sharp heat pump;
-
provided the customer with all warranty information and explained proper usage practices.
