What is a Mini Split AC Unit?
A mini split AC unit is a ductless heating and cooling system that consists of an indoor air-handling unit paired with an outdoor compressor. Unlike traditional central air systems, mini splits require no expensive ductwork, allowing them to deliver targeted, highly efficient climate control directly to individual rooms or zones. They are widely used by homeowners looking to cool specific hot spots, additions, or entire homes with minimal energy waste and whisper-quiet operation.
