A Seamless HVAC Upgrade: Delivering Comfort and Energy Efficiency
In our latest installation, we had the pleasure of working on a project in Verdun, one of Montreal’s most vibrant neighborhoods. The client was in search of an energy-efficient and sleek HVAC system, and after assessing their needs, we recommended the Gree Sapphire 12,000 BTU Wall-Mounted Heat Pump. This unit is not only Energy Star® certified but also offers exceptional performance in both cooling and heating, even in Montreal’s extreme winter temperatures of -30°C.
Let’s dive into why the Gree Sapphire is a top choice for homeowners and how our installation process reflects the AirGreen commitment to quality and customer satisfaction.
Why the Gree Sapphire Stands Out
When selecting a heat pump, it’s important to balance both functionality and aesthetics. The Gree Sapphire does exactly that, offering an incredibly sleek design while maintaining high efficiency and durability. Here’s why the Gree Sapphire is the perfect fit for homeowners in Quebec, where winters can be brutal and summers hot and humid.
-
High SEER Rating: With an impressive 30.5 SEER efficiency, the Sapphire provides superior energy savings in cooling mode. This means lower energy bills throughout the hot summer months.
-
Ultra-Efficient Heating: Able to heat your home in temperatures as low as -30°C, the Sapphire ensures warmth during Montreal’s harshest winters. This feature was especially appealing for our Verdun client who needed reliable year-round comfort.
-
Quiet Operation: With sound pressure levels as low as 22 dB(A) indoors, this unit offers whisper-quiet performance—perfect for maintaining peace in the home without sacrificing comfort.
-
Built-in WiFi: Control the Sapphire from anywhere via the Gree+ app. This smart technology allows users to adjust settings remotely, making it easy to arrive home to the perfect indoor climate.
Installation Process: Precision and Expertise
At AirGreen, we believe that a perfect installation is just as important as selecting the right equipment. This installation in Verdun was no exception. Our certified technicians executed the project seamlessly, keeping the client informed every step of the way.
Step 1: Assessing the Site
Before beginning the installation, we conducted a thorough assessment of the client's space. Given the dimensions of the interior unit (39.88 x 8.75 x 12.13), we ensured that the unit would fit perfectly in the designated wall space, providing unobstructed airflow for maximum efficiency.
Step 2: Preparing the Installation
The exterior unit is a crucial component in any heat pump system, and the Gree Sapphire’s external unit measures 35.41 x 14.88 x 23.5—compact yet powerful. We positioned the outdoor unit on a secure mounting system to minimize vibration and reduce noise. The client’s home was a few stories high, so our team took extra care in routing the refrigerant lines and piping (1/4 - 1/2) through the building structure, ensuring a clean, professional finish.
Step 3: Mounting and Connecting
Once the units were in place, we connected the system, ensuring that both the cooling and heating capacities of 12,000 BTU would function optimally. We used high-quality insulation for the refrigerant pipes to prevent energy loss and ensure the longevity of the system. The R-410A refrigerant used in this system is eco-friendly, aligning with modern environmental standards.
Step 4: Fine-Tuning and Testing
With everything installed, our technicians ran multiple tests to ensure the system was operating efficiently. We paid particular attention to the WiFi feature, walking the client through the process of connecting their phone to the Gree+ app. This feature allows the homeowner to monitor and control their HVAC system remotely, a must-have in today’s smart home environment.
Why Choose AirGreen?
Choosing the right HVAC system is only half the battle. At AirGreen, we understand that professional installation can make all the difference between a system that lasts for years and one that faces frequent issues. Here’s why our clients trust us:
-
Expert Technicians: Our team is trained in the latest HVAC technologies and installation techniques, ensuring every job is done to the highest standards.
-
Personalized Service: We take the time to understand each client’s unique needs and provide tailored recommendations. In this case, the Gree Sapphire was a perfect fit due to its energy efficiency, low noise level, and heating capabilities, ideal for Quebec's climate.
-
Government Grants: The Gree Sapphire is eligible for a $972 LogisVert Grant from Hydro-Québec, which helps homeowners offset the initial cost of installation. We guided the Verdun client through the grant application process, ensuring they could take full advantage of the available financial incentives.
The Environmental Benefits of the Gree Sapphire
The Gree Sapphire doesn’t just offer superior comfort; it’s also an environmentally friendly choice. Its Energy Star® certification means it uses less energy, reducing your home’s carbon footprint. In a city like Montreal, where sustainability is increasingly important, installing an energy-efficient heat pump is a great way to contribute to a greener future.
Moreover, the unit’s use of R-410A refrigerant is much more environmentally friendly than older refrigerants, reducing its impact on the ozone layer. For eco-conscious homeowners, this is a key selling point.
Client Satisfaction: Our Priority
Throughout the installation, we maintained open communication with the client, ensuring they were comfortable and informed about every step of the process. From selecting the right model to ensuring that the installation was completed efficiently, we prioritized their needs.
The client in Verdun was particularly impressed with the quiet operation of the Gree Sapphire—it’s almost silent indoors, even when operating at full capacity. They also appreciated the sleek, modern design, which blends seamlessly into the home’s interior without being obtrusive.

The job tools
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.
How the job unfolds
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.
Remote, modes, filters: we show you the essentials before we leave.

What we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.
Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
The right pages, at the right time
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
