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.

If you’ve been searching for a cooling and heating system that doesn’t just perform but excels, let us take you through the details of this impressive installation.
Why the Gree Extrême is the Ultimate Choice for Canadian Winters and Summers
The Gree Extrême series has gained a reputation as a leader in the HVAC industry, especially for the challenging Canadian climate. This particular model is designed to handle temperatures as low as -30°C, ensuring that even during the coldest winter nights, you stay warm and comfortable without a hitch. Here are some reasons why this model shines:
- Unmatched Heating and Cooling Performance: With a cooling capacity of 24,000 BTU and heating capabilities that excel in sub-zero temperatures, this unit is ready for any season. It’s like having two machines in one!
- Energy Efficiency: The Gree Extrême boasts a SEER rating of 21.5, meaning it’s not just effective but also extremely efficient, translating into lower electricity bills for you.
- Advanced G10 Inverter Technology: This patented technology ensures that the compressor operates smoothly, reducing noise, vibration, and energy consumption.
The Installation Process: Making Comfort a Reality in Brossard
The process of installing this high-performing unit involved meticulous planning and execution by our experienced team. Here’s a step-by-step breakdown of how we ensured this air conditioner would function at its peak:
-
Site Assessment and Preparation: We began with a thorough evaluation of the home’s layout in Brossard to determine the optimal location for both the indoor and outdoor units. This ensures maximum efficiency and comfort.
-
Mounting the Indoor Unit: The interior unit of the Gree Extrême, with its sleek dimensions of 42.52 x 9.66 x 12.81 inches, was carefully positioned to ensure seamless integration with the room’s décor. Its compact size means it doesn’t intrude into your living space but delivers powerful air conditioning and heating right where you need it.
-
Outdoor Unit Installation: The robust outdoor unit, measuring 38.56 x 16.81 x 31.11 inches, was mounted securely on a solid foundation. This ensures that the unit remains stable even during extreme weather conditions, preventing any vibrations or noise disturbances.
-
Connecting the Refrigerant Lines: The copper piping (1/4 and 5/8) was connected with precision, ensuring a leak-free, efficient flow of refrigerant between the indoor and outdoor units. This step is crucial for the optimal performance of the unit.
-
Electrical Wiring and Testing: We carefully connected the unit to a 220V power supply, tested the system, and ensured that everything was operating perfectly. Safety and efficiency are our top priorities during every installation.
Unique Features of the Gree Extrême That Make It Stand Out
- WiFi Integration: This unit comes with built-in WiFi capabilities, allowing homeowners to control their air conditioner from their smartphone. Adjusting the temperature from the comfort of your couch or even when you’re not home has never been easier.
- Ultra-Quiet Operation: With sound levels as low as 34 dB(A) indoors and 59 dB(A) outdoors, the Gree Extrême is perfect for those who value peace and quiet. Whether you’re sleeping, working, or relaxing, this unit won’t disturb you.
- Intelligent Defrosting: The Gree Extrême is equipped with a microprocessor-controlled defrosting system that activates only when necessary, ensuring efficient operation and energy savings.
Grants and Financial Benefits for This Installation
One of the most appealing aspects of this installation is its eligibility for the $1,860 LogisVert Grant by Hydro-Québec, significantly reducing the upfront cost for homeowners. Additionally, with its Energy Star® certification, this Gree model is also eligible for a federal grant of up to $2,500 / $5,000. This means substantial savings, making this high-quality system even more accessible.

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.
