Split systems help to reduce the amount of energy used and ensure you're not wasting power. Multi split system air conditioners have the added benefit of operating more than one indoor unit but is still one of the most energy efficient air con systems around.Unlike a system that requires a series of  networked throughout the ceiling, split air conditioners rely on a set of pipes to connect the outdoor to the inside air unit which is why they are referred to as a ductless mini-split air conditioner installation.Inverters are used in air conditioning equipment to vary, to modulate the speed of the compressor, as opposed to a standard split system which just cycles the compressor on and off to maintain temperature control.
