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.
Efficiency and Comfort in One Sleek Package
A Seamless Installation Journey
When it comes to enhancing the comfort of your home with the latest in air conditioning technology, the details of the installation process are just as crucial as the capabilities of the equipment itself. At AirGreen, we pride ourselves on providing not just advanced HVAC solutions, but also on ensuring that each installation is a smooth, stress-free experience for our clients. Our recent project in Dorval, Montreal, serves as a prime example of this commitment.
The Simplicity of Perfect Placement
Choosing the right location for both the indoor and outdoor units of an air conditioner can significantly affect its efficiency and performance. In this instance, the homeowner benefited immensely as both units were installed on the same wall—directly opposite each other. This ideal placement meant that we could minimize the length of piping and wiring required, which not only streamlined the entire installation but also led to considerable cost savings for the homeowner.
The proximity of the electrical panel to the compressor was another fortunate aspect of this project. With everything so conveniently placed, our team was able to complete the installation swiftly and without any unnecessary disruptions to the homeowner's daily life.
Client Delight and Referrals
Our client's satisfaction with the installation of the Gree Vireo GEN3 was palpable. This 9000 BTU model, known for its compact design and silent operation, fits unobtrusively into the living space while providing exceptional cooling. It's no surprise that our client was so pleased that they recommended AirGreen to a friend, leading to another similar installation shortly thereafter.

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.
