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.
Efficient Climate Control Meets Ingenious Space Management
At AirGreen, we specialize in providing top-notch HVAC solutions that not only enhance the comfort of your home but also complement your living space. Our recent installation in Dollard-des-Ormeaux, Montreal, showcases our commitment to innovative and efficient climate control solutions. The GREE LIVO GEN4, a 12,000 BTU wall-mounted heat pump, stands out not just for its superior efficiency and powerful performance but also for its clever installation that maximizes space utility.
The Challenge: Maximizing Limited Balcony Space
Our customer faced a unique challenge: they wanted to enjoy the benefits of a high-efficiency heat pump without sacrificing the precious outdoor space of their small balcony. Recognizing the importance of every square inch, AirGreen devised a solution that would keep the balcony open and accessible while ensuring optimal climate control.
The GREE LIVO GEN4 Solution
This GREE model is not only robust in functionality but also in its space-saving design. Equipped with a high SEER rating of 18.5 for energy efficiency, this heat pump offers exceptional cooling and heating capabilities, suitable for temperatures ranging from -25°C to 50°C. The installation involved mounting the outdoor unit directly to the wall, high enough to preserve the functionality and aesthetic of the balcony space. This strategic placement not only safeguarded the client's outdoor area but also optimized the unit's performance.
Key Features of the GREE LIVO GEN4:
- High Efficiency: With an 18.5 SEER rating, this unit provides significant energy savings.
- Comprehensive Warranty: 12 years for both the compressor and parts, ensuring peace of mind.
- Smart Technology: Features like WiFi connectivity, multiple fan speeds, and intelligent pre-heating enhance user convenience and comfort.
- Quiet Operation: Maintains a low sound pressure level of 52 dB(A) outdoors and between 27 to 47 dB(A) indoors, ensuring minimal noise disturbance.
- Eco-Friendly: Utilizes R-410A refrigerant, which is known for its lower environmental impact.
Installation Details and Customer Satisfaction
The installation process was meticulously planned to align with the client’s requirements. The compact design of the GREE LIVO GEN4 allowed for a seamless fit on the exterior wall, eliminating any intrusion into the balcony’s space. This thoughtful installation not only optimized the physical footprint but also maintained the aesthetic integrity of the property.
The client was particularly impressed with the ability to control the unit via WiFi, which allows for convenient adjustments and monitoring of their home climate from anywhere. Furthermore, the eligibility of this model for a $350 LogisVert grant by Hydro-Québec added an extra layer of satisfaction, making this investment even more rewarding.

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.
