The part that connects a window air conditioner to the window is called a "window installation kit" or a "window installation bracket." This kit typically includes various components, such as adjustable panels or side curtains, screws, and foam insulation strips, which help secure and seal the air conditioner in the window opening.
The installation kit is essential for proper installation and ensures that the window air conditioner fits securely in the window frame, preventing air leaks and maximizing its cooling efficiency. Different air conditioner models may come with specific installation kits designed to fit their dimensions and requirements. It's essential to follow the manufacturer's instructions and use the correct installation kit for your window air conditioner to ensure safe and effective operation.
