what is a split system central air system
Types of Central Air Conditioners. A central air conditioner is either a split-system unit or a packaged unit. In a split-system central air conditioner, an outdoor metal cabinet contains the condenser and compressor, and an indoor cabinet contains the evaporator. In many split-system air conditioners, this indoor cabinet also contains a furnace or the indoor part of a heat pump.
Split-system air conditioners come in two forms: central and mini-split. In both types, the inside-environment (evaporative) heat exchanger and fan is separated by some distance from the outside-environment (condenser) heat exchanger and fan.
