Mini- and multi-split air conditioning systems, also called ductless heat pumps, are a newer subset of split air conditioners. A split-system air conditioner splits the hot side from the cold side of the system, as in the diagram below. And, as with a split system, the unwanted heat is released to the outside through the condenser coil. Thankfully, though, the truth is that most terms are actually quite simple once you have a basic understanding. Timeline followed perfectly.
