In this project in Chomedey, Laval , our team was called in to complete the installation of a Gree wall-mounted heat pump in a residential building. The indoor wall unit ensures the comfort of the occupants; here, we see its outdoor heart: the Gree compressor, optimally installed on the foundation wall near the garage entrance.
This step is crucial: even the best heat pump cannot perform at its full potential if the outdoor unit is poorly positioned, inadequately protected, or improperly secured. Therefore, we treated this installation with the same care as the rest of the system.
A Gree wall-mounted heat pump for four-season comfort
The chosen system is a Gree Inverter wall-mounted heat pump , with a capacity of approximately 12,000 to 18,000 BTU, perfectly sized for a typical Chomedey dwelling (condo, townhouse or compact single-family home).
This heat pump allows you to:
-
To provide effective air conditioning in summer, even during the intense heat waves that Greater Montreal is increasingly experiencing.
-
To heat efficiently in spring, autumn and a good part of winter, reducing reliance on electric baseboard heaters.
-
To save energy thanks to Inverter technology, which automatically modulates the power instead of operating in on or off mode.
With Gree, we have the combination our customers are looking for: reliability, performance in cold climates and good value for money.
An outdoor positioning designed for the Laval climate
The photo shows the compressor securely mounted on wall brackets anchored in the concrete foundation. This choice is not merely aesthetic: it has a direct impact on the lifespan and performance of the unit.
We have :
-
Elevate the unit above ground level to protect it from snow accumulation, ice, and thawing puddles.
-
Take advantage of the overhanging concrete slab to offer natural protection against driving rain and snow falling directly from the sky.
-
Position the device so as to leave sufficient clearance at the front for air circulation and automatic defrosting operations.
This positioning, both protected and well ventilated, is ideal for ensuring stable operation in winter and summer, even when it is very cold on the North Shore.
Robust fixings and vibration reduction
The metal brackets used are specifically designed for wall-mounted heat pumps. They are:
-
Mechanically anchored in the concrete using fixings sized for the weight of the compressor and wind forces.
-
Equipped with anti-vibration pads that absorb the micro-vibrations generated by the compressor and fan.
Result: less transmission of vibrations to the building structure and quieter operation, both for occupants and for the neighborhood.
We also note the clean routing of the refrigeration pipes and wiring behind the unit, which simplifies future maintenance and avoids the risk of mechanical damage.
Defrosting and water drainage management
In heating mode, an outdoor heat pump produces condensation and ice during defrost cycles. To prevent problems:
-
We left a clearance under the unit so that the defrost water could drain freely and the ice would not touch the bottom of the housing.
-
Positioning on a concrete wall prevents defrosting from damaging fragile surfaces (wood, light cladding, etc.).
-
The unit remains easily accessible for early or late season maintenance: cleaning, inspection, defrosting check.
These practical details often make the difference between an installation that ages well and one that causes problems after a few winters.
Careful integration around the garage
The Gree outdoor unit is installed near the door leading to the garage or workshop , in a passageway but without obstructing traffic. We have:
-
Respect the necessary clearances to open the door without risk of impact.
-
Position the device at a height that allows for easy maneuvering of stored vehicles, tools or equipment.
-
Optimized the length of the refrigeration lines to reduce pressure losses and facilitate communication with the indoor unit.
The overall effect is a functional, tidy installation, aligned with the semi-industrial style of the concrete structure and complemented by the horizontal cladding of the facade. Our AirGreen sticker is also visible, a reminder that the installation was carried out by a specialized HVAC team.
