A custom installation for a modern South Shore home
At AirGreen , we understand that every HVAC installation project has its own unique characteristics. This is exactly what we found during this installation of a Willis wall-mounted heat pump in a residence in Sainte-Julie , on the South Shore of Montreal. The client wanted to optimize their comfort in both summer and winter while benefiting from a reliable, energy-efficient system that was eligible for available grant programs.
Why the Willis wall-mounted heat pump?
The Willis brand is renowned for its compact, high-performance units, ideal for residential properties in the greater Montreal area. In this case, the chosen model offered:
-
A capacity adapted to the needs of the house ( BTU sizing adjusted according to the surface area and insulation).
-
Stable operation in heating mode even at low temperatures.
-
Energy efficiency in accordance with the criteria of Quebec government programs .
-
Reliability adapted to the harsh winters of the South Shore .
Technical details of the installation
Our team installed the outdoor condenser on a galvanized steel wall bracket , securely fixed to the concrete facade adjacent to the garage. This configuration has several advantages:
-
Optimal ground clearance : protection against snow accumulation and debris.
-
Enhanced stability : robust mounting minimizes vibrations.
-
Easy accessibility for maintenance and periodic inspections.
The refrigerant lines and electrical wiring were carefully sheathed and connected to a sealed junction box, ensuring the safety and durability of the installation. The tubing length was optimized to reduce energy losses and maintain the machine's nominal performance.
The challenges encountered and our solutions
Every project presents its challenges. In this case, we were working on a decorative stone façade combined with a smooth concrete base. Our technicians used specialized anchors to ensure impeccable fixation without compromising the aesthetics or watertightness of the structure.
Another aspect concerned the working height. Since the unit was installed several meters above the ground, we used secure equipment to comply with workplace safety standards, while ensuring a precise and durable installation.
Results obtained
Upon completion, the client immediately noticed a difference in comfort and noise reduction. The Willis outdoor unit operates quietly, and the interior of the home benefits from even heating and cooling.
In addition to comfort, the owner now benefits from:
-
Significant energy savings on annual bills.
-
Eligibility for provincial and federal grants , which reduce the initial investment.
-
A scalable and sustainable system, capable of meeting seasonal needs efficiently.
