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 Seamless Integration of Comfort and Aesthetics
In the charming community of Rosemère on Montreal's North Shore, our latest project at AirGreen highlights not only our commitment to delivering top-tier HVAC solutions but also our dedication to aesthetic excellence and customer satisfaction. This detailed account not only showcases the installation of a GREE LIVO GEN4 wall-mounted heat pump but also illustrates our meticulous approach to overcoming structural challenges, ensuring that each project blends seamlessly into the decor of our clients' homes.
The Challenge of Visible Piping
Often, the biggest challenge in residential HVAC installations isn't the installation itself but ensuring the equipment integrates well with the home's design. In this particular project, the structure of the home did not allow for hiding the heat pump's piping within the walls or ceiling. This is a common issue many homeowners face, but it is one that we at AirGreen are prepared to tackle creatively.
Understanding our client’s desire for a clean look, we recommended a professional plasterer from our trusted network. After our installation was complete, the plasterer constructed a custom box to encase the pipes. This solution was not only functional but also aesthetically pleasing. The box was then painted to match the room’s color scheme, ensuring that the heat pump’s presence was felt only through the comfort it provided, and not through any visual discordance.
The GREE LIVO GEN4: A Synthesis of Technology and Efficiency
The GREE LIVO GEN4 wall-mounted heat pump is renowned for its exceptional efficiency and cutting-edge features. With a cooling capacity of 18,000 BTU and a heating limit that extends down to -25 °C, it stands as a formidable solution for climate control. The model's 18.5 SEER efficiency rating is a testament to its design, aimed at reducing electricity usage while maximizing output.
Key features include:
- Inverter G10 Technology: This technology adjusts the motor speed in real time, based on the needs of the room, which minimizes energy consumption and maintains consistent temperatures.
- I-Feel Function: This feature uses sensors in the remote control to adjust the room temperature to where you are, ensuring personalized comfort.
- Multiple Fan Speeds and Intelligent Preheating: These allow the system to quickly reach the desired temperature and maintain it with minimal fluctuation.
- WiFi Connectivity: Allows homeowners to control their climate settings from anywhere, directly from their smartphones.
Additionally, this model is equipped with a resin-coated coil and includes features like sleep mode, auto-clean, low-voltage start-up, and auto-diagnosis for troubleshooting. Such comprehensive functionality ensures that the GREE LIVO GEN4 is not only effective but also user-friendly and durable.
Collaboration and Customer Satisfaction
The success of this installation in Rosemère was not just due to the high-quality heat pump or our technical expertise; it was also a result of the collaborative effort between AirGreen, our client, and the skilled plasterer who provided the finishing touches. This project exemplifies our holistic approach to HVAC installation—where functionality meets design.

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.
