A split system air conditioner is a type of air conditioning system that is made up of two main components: an outdoor unit and an indoor unit. The outdoor unit is usually installed outside the home and houses the compressor, condenser, and other components. The indoor unit is usually installed inside the home and contains the evaporator, blower, and other components. The two units are connected by refrigerant lines, which allow the air conditioning system to move cooled air from the outdoor unit to the indoor unit. Split system air conditioners are popular because they are relatively easy to install and can be used to cool a single room or an entire home. They are also energy efficient and can help reduce energy costs. Additionally, split system air conditioners are available in a variety of sizes and styles, making them a great choice for any home.
