Mini-split air conditioning systems operate on a simple concept: indoor units connected to outdoor condensing units with refrigerant line-sets. This creates some key advantages over traditional air conditioning systems. With mini-splits there is easy temperature control among zones, no ductwork, and no noisy units blocking windows.
The fact that indoor mini-split units receive their electrical power directly from the outdoor unit can be easy to overlook. But, when it comes to designing a room, this may be the biggest plus of installing a mini-split. Outdoor units usually require a dedicated circuit for power. Wiring will run, alongside the line-set, to each indoor unit. This means no plugs or wires will be visible in the living space.
