A mini-split system is a type of heating and cooling system that consists of an outdoor compressor unit and one or more indoor air-handling units. These systems are known for their energy efficiency and flexibility, allowing homeowners to control the temperature in individual rooms or zones. Unlike traditional central air conditioning systems, mini-splits do not require ductwork, making them easier to install in homes without existing ducts. They are ideal for retrofitting older buildings or for use in new constructions, providing both heating and cooling options in a compact design.
