At AirGreen, we are committed to providing high-quality heating, ventilation, and air conditioning (HVAC) solutions to our clients. During our most recent installation in Viauville, we installed a GREE Sapphire R32 wall-mounted heat pump, a highly sought-after unit for its energy efficiency and sleek design. This article delves into the details of this installation, its benefits, and the unique challenges we faced during this project.
A Modern and Efficient Installation with the GREE Sapphire R32
The GREE Sapphire R32 model is designed to offer optimal performance in both heating and cooling. This model uses the R32 refrigerant, known for its low environmental impact, making it more eco-friendly than previous models that used R410A. With impressive specifications such as a cooling capacity ranging from 7,971 to 35,308 BTU/h and a heating capacity ranging from 8,134 to 32,879 BTU/h, this heat pump is perfect for residential and commercial installations of medium to large sizes.
Features of the GREE Sapphire R32 Heat Pump
-
Exceptional Energy Efficiency: This model boasts exceptional energy efficiency, with a SEER2 rating of up to 30.0, placing it among the top in its category in terms of energy consumption.
-
Wide Temperature Range: The GREE Sapphire operates within very wide temperature ranges, from -20°F to 122°F for cooling and -22°F to 86°F for heating, ensuring reliable use even in extreme weather conditions.
-
Intelligent Control Technology: Features such as airflow direction control, intelligent pre-heating, and auto-cleaning mode enhance the unit’s lifespan while ensuring consistent performance.
-
Acoustic Comfort: Thanks to its quiet operation, the indoor unit produces sound pressure levels ranging from 23 to 53 dB(A), ensuring optimal comfort without noise disruptions.
The Installation Process in Viauville
During the installation of the GREE Sapphire R32 wall-mounted heat pump in Viauville, one of the main challenges was finding the ideal location for the outdoor unit. The available space in the underground parking lot was limited, and we had to ensure that the unit was mounted securely without blocking access or affecting the aesthetics of the area. Using specialized brackets to hold the outdoor unit while maximizing airflow ensured optimal efficiency.
We also took great care to protect the ducts and wiring to prevent damage and ensure the durability of the installation. Thanks to our expert technicians, we were able to carry out this installation quickly and efficiently, while adhering to strict safety and performance standards.
Why Choose the GREE Sapphire R32?
The GREE Sapphire R32 stands out for its versatility and reliability, in addition to its ability to meet various heating and cooling needs. For residents and businesses in Montréal, Laval, Longueuil, as well as surrounding areas like South Shore and North Shore, this heat pump is an excellent choice, primarily due to its advantages:

Customer Testimonial: Comfort Restored
The client in Viauville, after the installation of the GREE Sapphire R32 heat pump, immediately noticed the difference in terms of thermal comfort. Prior to the installation, temperature control in the space was difficult, with significant temperature variations between rooms. Thanks to the GREE Sapphire, the unit now ensures uniform and comfortable temperatures throughout the year, operating in heating mode during winter and cooling mode in summer.

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.
