A split system is a type of heating and cooling system commonly used in homes and buildings. It consists of two main components: an indoor unit and an outdoor unit. The indoor unit is responsible for distributing air throughout the space, while the outdoor unit contains the compressor and condenser. This design allows for efficient temperature control without the need for extensive ductwork. Split systems are popular for their flexibility and energy efficiency. They can be installed in various configurations, making them suitable for different room sizes and layouts. Additionally, many split systems offer features like programmable thermostats and multi-zone capabilities, allowing users to customize their comfort levels in different areas of the building.
