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.
A Masterpiece of Comfort and Efficiency
Nestled in the picturesque town of Oka, a recent HVAC installation by AirGreen has set a new standard for residential comfort and technological sophistication. The project involved the meticulous setup of a Gree Vireo GEN3 Mini Split Heat Pump, a model renowned for its exceptional energy efficiency and advanced technological features. This installation not only enhanced the home's climate control capabilities but also aligned with the homeowner's commitment to sustainability, thanks to the $550 grant from the LogisVert Program by Hydro-Québec.
Cutting-Edge Technology for Optimal Comfort
The Gree Vireo GEN3 is a marvel of modern HVAC technology, boasting a series of features designed to deliver unparalleled comfort and convenience. Here’s a glimpse into its standout attributes:
- High-Efficiency Ratings: With an impressive SEER (Seasonal Energy Efficiency Ratio) of 23.0, this heat pump optimizes energy use while providing robust heating and cooling.
- Wi-Fi Connectivity: Integrated Wi-Fi allows homeowners to control their indoor climate with the tap of a smartphone, blending seamlessly into the fabric of a smart home.
- Enhanced Durability: Equipped to handle temperatures as low as -30°C, the unit ensures consistent performance even during the harsh Canadian winters, making it a reliable choice for year-round comfort.
A Seamless Installation Journey
The installation process in Oka was a testament to AirGreen’s commitment to quality and customer satisfaction. The team faced unique challenges due to the layout and aesthetics of the home, requiring a strategic approach to ensure the unit complemented the interior design while maximizing its efficiency. The chosen location for the indoor unit was critical in maintaining the visual appeal of the home’s décor and ensuring optimal airflow.
Special attention was given to the placement of the outdoor unit, which was installed in a discreet location to preserve the home's external aesthetics while minimizing sound, thanks to its 57 dB(A) sound pressure level. The interior unit's quieter operation at 31 dB(A) ensures a tranquil environment, crucial for the homeowner's comfort.

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.
