In summer, the outdoor unit rejects the house's heat outside.

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.

The Installation Journey: Challenges & Triumphs
Embarking on this installation, our team was faced with the challenge of mounting three 12,000 BTU heads on a potent 36,000 BTU compressor. Each head was designated for a different floor, requiring meticulous planning and execution.
First & Second Floors: Smooth Sailing
The living rooms on the first and second floors aligned with the compressor's location, facilitating a straightforward installation for these heads. A bit of height work was necessary for installing the aluminum cover for the pipes, but it was all in a day’s work for our seasoned professionals.
Basement Installation: A Unique Challenge
The basement presented a different scenario. With the living room situated at the apartment’s center, our team navigated through two rooms to reach the installation point. This head required an additional drain pump installation to prevent water leakage during humid summer days, ensuring a dry and comfortable environment.
Finishing Touches: Excellence in Every Detail
Our collaboration with a professional plasterer was crucial in achieving a flawless finish. The expertly installed gyprock and fresh coat of paint provided a sleek look, encapsulating the high-quality work that defines AirGreen.

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.
