Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.

Why Saint-Lambert is the Perfect Location for the Gree Sapphire
Saint-Lambert, located on Montreal's South Shore, experiences a wide range of temperatures throughout the year. With harsh winters and hot summers, having a reliable HVAC system is crucial. The Gree Sapphire is ideal for this region, as it delivers efficient heating even in extreme cold, down to -30°C, and offers effective cooling during summer heatwaves.
By choosing the Gree Sapphire, our client in Saint-Lambert can now maintain the perfect indoor climate regardless of the season, without worrying about exorbitant energy bills.
The Installation Process: Ensuring Seamless Performance
Our team at AirGreen takes pride in providing a smooth and efficient installation process, ensuring that every detail is handled with precision. Here’s a breakdown of how we approached this installation:
1. Site Assessment and Preparation
We started by thoroughly inspecting the client's home in Saint-Lambert to identify the optimal location for the wall-mounted unit. This step is crucial to ensure the system operates efficiently and effectively, providing even heating and cooling throughout the space.
2. Mounting the Interior Unit
The indoor unit was carefully mounted above a doorway, ensuring it would provide maximum airflow and coverage throughout the room. The unit's dimensions (44.19 x 9.81 x 13 inches) make it a perfect fit for various spaces, and its sleek design blends seamlessly with any decor.
3. Installing the Exterior Unit
Next, we installed the outdoor unit, measuring 38.63 x 16.81 x 31.13 inches, in a location that ensures optimal performance and minimal noise disturbance. The exterior sound pressure level of just 59 dB(A) ensures that our client enjoys a quiet and peaceful environment both inside and outside their home.
4. Connecting the Piping and Electrical Components
We used high-quality 1/4 - 5/8 pipes to connect the interior and exterior units, ensuring efficient refrigerant flow and long-lasting performance. The system was then connected to a 220V power supply, providing a stable energy source for the heat pump.
5. Testing and Final Adjustments
Once the installation was complete, our technicians thoroughly tested the Gree Sapphire heat pump to ensure it was operating at peak efficiency. We also took the time to explain the system's features and functions to the client, ensuring they could fully benefit from their new HVAC solution.
Unlocking Savings with the LogisVert Grant
One of the most exciting aspects of this installation is that the Gree Sapphire is eligible for a $1,704 LogisVert Grant from Hydro-Québec. This government incentive makes the Gree Sapphire an even more attractive option, as it helps offset the cost of installation while providing long-term energy savings.

And at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
