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.

This strategic installation showcases our commitment to providing high-quality, sustainable, and efficient heating solutions tailored to the harsh Canadian winters.
The Context of Our Latest Project
Located in the charming suburb of Rivière-des-Prairies–Pointe-aux-Trembles, this project involved outfitting a residential home with a state-of-the-art mini-split system designed to offer superior heating and cooling capabilities.

Choosing the GREE Extreme Mini Split
The homeowner opted for the GREE Extreme 18,000 BTU model due to its exceptional features and high efficiency. Renowned for its 24.5 SEER rating and ability to operate efficiently down to -30°C, this system is perfect for handling Montreal's extreme weather. Additionally, the inclusion of intelligent defrosting and two-stage compressor technology ensures that the unit operates at peak efficiency while minimizing energy costs.

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.
