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. This system allows for individual temperature control in different rooms or zones, making it energy-efficient and convenient for homes and businesses. Mini-split systems do not require ductwork, which makes them easier to install in spaces where traditional HVAC systems may not be feasible. They are often used in homes, offices, and additions to provide targeted comfort without the need for extensive renovations.
