The answer to 'how does mini split work' is a mini-split air conditioning system, also known as a ductless mini-split, is a type of HVAC system that provides heating and cooling without the need for ductwork. These systems consist of an outdoor compressor/condenser unit and one or more indoor air-handling units connected by refrigerant lines. The outdoor unit compresses and condenses refrigerant, which is then circulated through the refrigerant lines to the indoor unit(s). The indoor unit(s) use a fan to draw in warm or cool air from the room, pass it over the refrigerant coils, and then distribute the conditioned air back into the space.
Mini-splits are highly efficient and flexible, allowing for independent temperature control in different zones or rooms of a home. They are a popular choice for homes without existing ductwork, additions, or spaces that are difficult to condition with a traditional HVAC system.
