The size of a ductless mini-split system is determined by its cooling capacity, typically measured in BTUs (British Thermal Units). To choose the right size, consider the square footage of the space you want to cool. A general rule of thumb is 20-30 BTUs per square foot, but consulting with a professional for an accurate assessment is recommended.
