A split air conditioner is a type of cooling system that consists of two main components: an indoor unit and an outdoor unit. The indoor unit is installed inside the room, where it blows cool air, while the outdoor unit houses the compressor and condenser. This design allows for efficient cooling without taking up much space inside the home. Split air conditioners are popular for their quiet operation and energy efficiency. They can be used to cool individual rooms or larger areas, depending on the system's capacity. Many models also offer heating functions, making them versatile for year-round comfort.
