The answer to 'types of ductless system' is that ductless HVAC systems, also known as mini-split systems, are a type of air conditioning and heating system that does not require traditional ductwork. Instead, they use one or more small, wall-mounted indoor units connected to an outdoor compressor unit by refrigerant lines. Ductless systems are highly efficient and flexible, making them a popular choice for homes and buildings that cannot accommodate traditional ducted systems.
Ductless systems come in several different configurations, including single-zone and multi-zone systems. Single-zone systems have one indoor unit connected to one outdoor unit, while multi-zone systems can have up to eight indoor units connected to a single outdoor unit. This allows for individual temperature control in different rooms or zones of a building.
