Window installation system and method for split-architecture air conditioning unit

An air conditioning unit comprising:

• a bracket configured to be coupled to a sill of a window by widening or narrowing a cavity defined by the bracket to correspond to a thickness of the sill between an internal environment and external environment and by disposing the bracket over the sill with the sill within the cavity, the bracket comprising a pivot arm configured to be disposed extending away from the window and parallel to a top face of the bracket that extends over the sill, with the bracket defining guide slots disposed in parallel;
• and
• an external unit configured to be:
• positioned on top of the bracket with the external unit extending over the sill and out the window with an internal face of the external unit engaging the bracket, a bottom of the external unit facing the external environment outside the window and a top face of the external unit facing the internal environment inside the window;
• moved on the top of the bracket onto the pivot arm with the external unit secured within the guide slots of the bracket and secured within pivot arm guide slots of the pivot arm, the pivot arm guide slots in a first horizontal configuration;
• and
• rotated downward via the pivot arm such that the bottom of the external unit faces downward and the top of the external unit faces upward, with the external unit disposed in the external environment and extending downward below the sill of the window and with the internal face of the external unit facing the bracket, wherein the rotating the pivot arm downward causes the pivot arm guide slots of the pivot arm to rotate from the first horizontal configuration to a second vertical configuration.

An air conditioning unit comprising:

• a bracket configured to be coupled to a sill of an opening between a first environment and a second environment, the bracket comprising a pivot arm configured to be disposed and extending within the first environment, the bracket further configured to:
• have a first unit positioned on a top of the bracket;
• have the first unit moved on the top of the bracket onto the pivot arm;
• and
• have the pivot arm and the first unit rotated downward so that the first unit is disposed in the first environment and extending downward below the sill of the opening to cause one or more pivot arm guide slots of the pivot arm to rotate from a first configuration to a second configuration.
