In this project in Rosemont–La Petite-Patrie , Montreal, our AirGreen team modernized the comfort of a brick house by installing a Sharp Eco Inverter wall-mounted heat pump . The client's objective was clear: to have a reliable and economical system for heating and cooling the house, while maintaining a clean, safe, and durable outdoor installation for Montreal winters.
A typically Montreal context
The residence is a brick row house with an exposed concrete foundation and a narrow backyard, typical of Rosemont–La Petite-Patrie. The constraints were as follows:
-
Optimize the already limited ground space in the courtyard.
-
Protect the equipment from snow and ice accumulation.
-
Minimize noise for immediate neighbors.
-
Ensure an installation that meets standards, is aesthetically pleasing and easily accessible for maintenance.
After analyzing the thermal load and the occupants' lifestyle, we recommended a Sharp Eco Inverter wall-mounted heat pump, model Sharp ZHU1 12,000 BTU , perfectly suited to a main living area (living room, dining room, kitchen).
Why choose the Sharp Eco Inverter wall-mounted heat pump?
The Sharp brand is renowned for its cutting-edge technologies in residential air conditioning and heating. The Eco Inverter range offers an excellent balance between performance, energy consumption, and acoustic comfort.
The main advantages of this house in Rosemont–La Petite-Patrie:
-
Inverter technology : the heat pump continuously adjusts its power according to the actual demand, which ensures a more stable temperature and better energy efficiency.
-
Heating mode for Quebec climate : when properly sized, the Sharp ZHU1 heat pump is capable of providing comfortable heat for much of the winter, significantly reducing the electricity bill.
-
Quiet operation : the outdoor unit, with its large fan and protective grille, is designed to limit noise, which is essential in a dense area like Rosemont.
-
Plasmacluster Ion Technology : on the interior part, this purification technology helps to improve air quality by reducing dust and allergens.
A raised wall-mounted installation: designed for winter
The photo clearly shows the Sharp heat pump mounted on a brick wall, above the concrete slab , using a galvanized steel wall bracket . This type of mounting is not a minor detail; it is an integral part of the unit's performance and durability.
1. Protection against snow and ice
By raising the unit:
-
We protect it from snowbanks created by clearing snow from the yard or from the roof collapsing.
-
We reduce the risk of the fan being blocked by ice or blown snow.
-
We facilitate the drainage of defrost water, which can accumulate under the unit during defrost cycles in winter.
The result: a heat pump that defrosts properly, remains functional, and offers better performance even in cold weather.
2. Stability and safety
The wall mount is:
-
Securely anchored in the brick , with mechanical anchors adapted to the weight of the device.
-
Equipped with leveling screws to keep the unit perfectly horizontal, which is essential for compressor operation and condensate drainage.
-
Designed to absorb some of the vibrations and withstand freeze/thaw cycles.
We always ensure that the installation height complies with standards and allows safe access for maintenance.
3. Clearances and air circulation
The Sharp heat pump is installed at a sufficient distance from the wall to:
-
Allow good air circulation around the unit.
-
Avoid recirculating hot air in heating mode, as this could decrease the system's efficiency.
-
Facilitate the cleaning of the coils and the ventilation grille.
These details are essential to preserve the seasonal yield (SEER/HSPF) advertised by the manufacturer.
Electrical and refrigeration connections: cleanliness and compliance
Beneath the unit, the concrete foundation and a flat surface, which facilitates the connection work, are clearly visible. Our technicians have:
-
Install a disconnect (safety switch) near the unit, as required by electrical standards.
-
Route the refrigeration lines and power cable in an orderly manner, with appropriate fixings to avoid any chafing or pinching.
-
Pressures were checked, a vacuum was evacuated from the lines and a leak test was performed before commissioning.
This rigor is directly reflected in the reliability of the system and the validity of the manufacturer's warranty.
Four-season comfort for the occupants
Inside, the Sharp wall-mounted unit paired with this Eco Inverter condenser offers:
-
Fast and gentle air conditioning in the summer , ideal for the heat waves of July and August in Montreal.
-
A very effective supplementary heating source during the shoulder seasons and for a good part of the winter, which reduces the load on electric baseboard heaters or any other existing system.
-
Precise temperature control , thanks to the integrated thermostat and the different modes (heating, cooling, dehumidification, ventilation).
-
Improved air quality , especially for occupants sensitive to allergens.
Owners thus benefit from constant comfort, while reducing their energy costs.
