The answer to 'what is mini split' is a type of air conditioning and heating system that consists of an outdoor compressor/condenser unit and one or more indoor air-handling units. Mini-split systems are ductless, meaning they do not require the extensive ductwork of a central HVAC system. Instead, the indoor unit is connected to the outdoor unit by a refrigerant line, allowing for flexible placement and zoned temperature control.
Mini-split systems are a popular choice for homes and buildings without existing ductwork, or for adding cooling and heating to specific rooms or areas. They are highly efficient, energy-saving, and allow for customized climate control in each zone. Mini-splits are typically easier to install than a full central HVAC system, making them a good option for retrofitting or additions.
