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.

Project Overview: Seamless Integration During Renovation
Our latest project involved the installation of a Gree Vita wall-mounted air conditioner for a customer in the midst of extensive home renovations. This installation was not just about adding an air conditioner; it was about integrating comfort seamlessly into a newly revitalized living space without compromising the aesthetics or functionality of the home.
The Challenge: Minimal Disruption, Maximum Efficiency
Initially, our client was concerned about the potential disruptions to his home’s interior due to the installation process. He anticipated multiple holes and visible wiring that could detract from the clean look of his renovation. However, our skilled technicians at AirGreen handled the installation with an unexpected finesse that left the client thoroughly impressed.
Technical Excellence and Customer Satisfaction

- Quiet Operation: The unit operates at a noise level of 27 to 47 dB(A) indoors, ensuring a quiet, serene indoor environment, which is crucial during the post-renovation period when peace and comfort are highly valued.
Client Testimonial: Beyond Expectations
Our client's feedback post-installation was overwhelmingly positive. He expressed deep satisfaction with the clean and professional approach taken by our team. The efficient and respectful installation process meant that his renovated space was enhanced rather than disrupted by the addition of the air conditioner. He appreciated the value for money, noting the unit's efficiency, the 10-year warranty on compressor parts and labor, and the aesthetically pleasing outcome.

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.
