Home Depot window air conditioners are self-contained cooling units installed in a window frame to provide localised cooling in a room. They typically consist of a compressor, a condenser, an evaporator, and a fan, and are designed to cool a specific area rather than an entire home.
Window air conditioners offer several advantages, including affordability, ease of installation, and energy efficiency. The first window air conditioner was invented in 1931 by H.H. Schultz and J.Q. Sherman, and has since become a popular choice for cooling homes and offices.
