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.
Bringing Unmatched Comfort to Every Corner: The Gree Sapphire Installation Journey
At AirGreen, we take immense pride in transforming spaces across Montreal, Laval, Longueuil, and beyond, with our top-tier HVAC installations. Recently, we had the opportunity to install a Gree Sapphire 12,000 BTU wall-mounted heat pump in the vibrant neighborhood of Côte-des-Neiges-Notre-Dame-de-Grâce. This wasn’t just any routine installation—it was a story of design finesse, technical precision, and a commitment to delivering unparalleled comfort, even during the harshest of Montreal winters.
Why the Gree Sapphire?
The Gree Sapphire series is renowned for its efficiency, sleek design, and cutting-edge technology. For this particular installation, our client wanted more than just a cooling solution—they needed a high-performance heat pump capable of handling Montreal’s extreme temperatures, especially in the depths of winter where temperatures can dip well below freezing. The Gree Sapphire model, with its exceptional heating capacity of -30°C, was the perfect choice.
The Details Behind the Installation
We began this project with a careful analysis of the client’s living space—a modern, spacious condo with large windows overlooking a beautiful part of Montreal. The challenge was to ensure the unit’s outdoor component was installed in a manner that would maximize efficiency without compromising aesthetics or the view from the balcony.
- Model: Gree Sapphire 12,000 BTU
- Cooling Capacity: 12,000 BTU
- Heating Capacity: Effective down to -30°C
- Energy Efficiency: Up to 30.5 SEER, ensuring the highest energy savings year-round
- Dimensions (Interior): 39.88" L x 8.75" D x 12.13" H
- Dimensions (Exterior): 35.41" L x 14.88" D x 23.5" H
- Noise Level: An ultra-quiet operation with a sound pressure level of 22-49 dB(A) indoors and 53 dB(A) outdoors, making it almost unnoticeable even when operating at full capacity.
Precision in Every Step
The Gree Sapphire is not just about performance—it’s about blending seamlessly with the client’s home. We made sure that both the indoor and outdoor units were positioned perfectly, ensuring optimal airflow and minimal visual impact.
Indoor Unit Placement:
The sleek, low-profile interior unit was installed in the main living area, where it would be most effective at evenly distributing cool air during the summer and providing warmth in the winter. Its minimalistic design fits beautifully with the condo’s modern aesthetic, proving that functionality doesn’t have to come at the expense of style.
Outdoor Unit Installation:
Outdoor units often pose a greater challenge, especially in urban settings. For this project, the exterior unit was mounted on the balcony. We used specialized brackets to ensure stability while maintaining enough space for proper airflow. The design of the Gree Sapphire outdoor unit is compact, which was essential for not obstructing the client’s panoramic view of the city.
The placement also needed to comply with condo regulations regarding noise levels, which the Gree Sapphire comfortably adheres to with its quiet outdoor operation. Even at full performance, the unit generates just 53.0 dB(A), quieter than most residential air conditioning units.
Grants and Energy Efficiency—A Great Deal for the Client
One of the most appealing aspects of the Gree Sapphire is its eligibility for several governmental grants, including Hydro-Québec’s LogisVert program, which offers a $972 rebate for this specific installation. The unit’s Energy Star certification and high SEER rating further ensure that the homeowner will benefit from reduced energy costs, making this a smart long-term investment.
Beyond the Technical Specs: A Personal Touch
While the installation process was smooth and efficient, what truly sets AirGreen apart is our commitment to client satisfaction. In this case, our team went the extra mile to explain every feature of the Gree Sapphire to the homeowner, ensuring they understood how to maximize their unit’s efficiency. From connecting the system to the WiFi-enabled Gree+ app to walking through the smart defrost and preheat features, we left no stone unturned.
Enhanced Comfort with Modern Features:
- WiFi Enabled: The homeowner can control the system remotely through the Gree+ app, adjusting the temperature and monitoring energy consumption from their smartphone.
- Multi-Speed Fan & Smart Defrost: The unit offers precise airflow control, with a multi-speed fan that adapts to the room's needs, keeping the space comfortable without wasting energy.
- Smart Preheating: Perfect for those cold Montreal mornings, this feature ensures that the system preheats before blowing warm air, enhancing overall comfort.
- Self-Diagnosis & Sleep Mode: These features offer peace of mind and user convenience, ensuring the system is always running smoothly without excessive energy usage.
A Seamless Integration into the Home
The Gree Sapphire’s sophisticated design was the perfect match for the condo’s contemporary interior. The client, a professional living in the Côte-des-Neiges-Notre-Dame-de-Grâce area, appreciated how the unit’s sleek lines complemented their modern décor. Additionally, the WiFi control feature allowed them to maintain the perfect temperature in their home with ease, especially on busy workdays.
Client Satisfaction and Final Thoughts
At the end of the installation, our client was thrilled—not just with the product, but with the level of service and attention to detail provided by AirGreen. They can now enjoy optimal indoor comfort year-round, whether it’s the humid summer months or the freezing cold of winter.
The combination of energy efficiency, smart features, and aesthetic appeal has made this installation one of our most satisfying projects to date. The Gree Sapphire, with its quiet operation and superior performance, is truly the ideal solution for Montreal’s unique climate challenges.

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.
