A mini-split system is a type of heating and cooling system that consists of two main components: an outdoor compressor and one or more indoor air-handling units. This system allows for individual temperature control in different rooms or zones, making it energy-efficient and versatile. Mini-splits are often used in homes without ductwork, providing a solution for both new constructions and retrofits. These systems operate using refrigerant to transfer heat between the indoor and outdoor units. They can be used for both cooling in the summer and heating in the winter, making them suitable for various climates. Mini-split systems are also known for their quiet operation and ease of installation compared to traditional HVAC systems.
