In Chomedey , a typical residential area of Laval with many brick houses featuring basements and bay windows, reliable thermal comfort is essential… without complicating the exterior design. It was precisely in this context that our AirGreen team installed aSharp wall-mounted heat pump , a compact, quiet system particularly well-suited to our Quebec winters.
For this project, the client wanted a solution capable of providing efficient heating in mid-season and winter , while offering precise air conditioning in summer , all with controlled energy consumption and a clean, durable and aesthetically pleasing installation.
The installed system: Sharp wall-mounted heat pump ( ZU1 series)
The type of equipment shown is a wall-mounted heat pump (mini-split) : a compact outdoor unit connected to a wall-mounted indoor unit (not visible here) via refrigerant lines and a drain. For this project, we selected a solution consistent with the unit pictured: the Sharp ZU1 (R-32) , a range known for its excellent balance of performance, comfort, and air quality.
What makes Sharp interesting in a neighborhood like Chomedey:
-
Inverter technology : the machine modulates its power instead of operating “ON/OFF”, which stabilizes the temperature and reduces electricity costs.
-
Acoustic comfort : both outside and inside, Sharp focuses on discreet operation, which is very important in a residential environment.
-
R-32 : a more modern refrigerant, with a good performance/environment compromise.
-
Plasmacluster (indicated on the unit): a signature Sharp feature, often appreciated by customers sensitive to indoor air quality.
A well-considered location: under the soffit, on a wall bracket, and with optimized clearance
The photo clearly shows an installation on aluminum wall brackets , under the soffit, near a basement window. This choice is not insignificant: in Laval, the realities of the terrain (snow, ice, freeze/thaw cycles, soil drainage) directly influence durability and performance.
Why a wall mount rather than a floor slab?
At AirGreen, we often prefer wall mounting when the site allows, because:
-
Protection against snow and ice banks : an elevated unit breathes better and remains less exposed to accumulations.
-
Reduction of vibrations transmitted to the ground : a good, well-anchored support limits resonance and improves acoustic comfort.
-
Easier maintenance : simpler access for inspection, seasonal cleaning and service as needed.
-
Drainage management : less risk of stagnant water around the device.
Clearance and air circulation
We also paid attention to the clearance around the fan . A heat pump performs best when it can draw in and expel air freely. Under the soffit, this is perfectly possible provided minimum distances are respected and the unit is positioned to avoid air recirculation.
Electrical connection and finishing: clean, safe and durable installation
Another important detail visible in the photo is the presence of an external electrical box (disconnect switch) , installed near the unit. This is an essential element for:
-
work safely during maintenance,
-
comply with installation requirements,
-
facilitate future interventions (diagnosis, maintenance, etc.).
We also take care with the routing of conduits and cables to achieve a clean and durable finish, especially on a brick facade where every penetration must be made cleanly , properly sealed, and protected against moisture.
Typical challenges in Chomedey (Laval)... and how they are managed
Even for a “simple” mini-split installation, there are local realities that must be anticipated.
1) Frost and snow
In Laval, rapid temperature variations and significant accumulations require a clear strategy: elevation , judicious positioning , and prevention of areas where snow could block air exchange.
2) The brick facades and respect for the building
A brick facade requires a solid and appropriate anchoring system. The goal: a durable fixing without weakening the wall, while maintaining an aesthetically pleasing installation.
3) Acoustic comfort near windows
Here, the unit is installed near a basement window. We take this seriously: stable support, precise mounting, and vibration checks. These are the details that make the difference between an acceptable installation and a truly “AirGreen” installation.
Why our customers choose a Sharp wall-mounted heat pump
For many homeowners in Laval, Sharp becomes a natural choice when they want to:
-
an energy-efficient system,
-
a brand renowned for comfort and air quality ,
-end a reliable machine for heating + air conditioning , -
a compact installation that respects the exterior aesthetics.
And above all: a solution well suited to housing where you want to improve a specific area (ground floor, open area, master bedroom), without transforming the entire mechanics of the building.
The AirGreen approach: performance, cleanliness and sustainable results
At AirGreen , our goal is not just to “install a machine”. We aim for a lasting result: efficiency , quiet operation , reliability , simple maintenance , and clean integration into the home.
In this project in Chomedey (Laval) , the installation illustrates exactly what we are looking for:
-
a relevant location,
-
a sturdy fixing,
-
a clear and secure connection
-
and a Sharp system consistent with the residential needs of the region.
If you are in Laval (Chomedey, Duvernay, Vimont, Sainte-Dorothée, etc.) and are considering a wall-mounted heat pump, we can guide you towards a solution that is truly suited to your home, your habits… and our climate.
