Perfect 260,000 BTU 230 Volt 21 SEER 1000 Sq Ft Smart Ductless Mini Split Air Conditioner and Heater with 25ft Installation Kit, Mini Split Heat Pump and AC · Ductless Mini Split · Mrcool · Bosch. The central air uses ducts and all rooms receive the same air treatment; with a mini split, each room is individually served by its own air handler. A ductless minisplit is a variant of the basic central air configuration, but instead of a single condenser feeding a single air handler, a ductless minisplit could have multiple air handlers. While central air uses powerful equipment to move staggering amounts of air throughout the house through ducts, minisplit systems isolate air movement to rooms where it's needed, using in-room air handlers for the task.
If you have an older home, it may not be possible to install air conditioning throughout the house due to lack of space for ducts. Ductless mini-split air conditioning systems consist of two main parts: an outdoor compressor or condenser combined with an indoor air handling unit. Room-by-room control enabled by ductless mini-divisions reduces energy costs better than a whole-house air conditioning system.
