Mini Split
A Mini Split is a modern type of air conditioning and heating system that doesn't need ducts to work. It consists of two main parts: an outdoor unit and one or more indoor units mounted on walls or ceilings. These systems are becoming very popular in homes and businesses because they're energy-efficient and allow different temperatures in different rooms. They're also called "ductless systems," "ductless mini splits," or "split-system air conditioners." HVAC technicians often work with these systems for installation, maintenance, and repairs.
