What is a Split System Air Conditioner?

A split system air conditioner uses liquid refrigerant to cool or heat the air. It comes in two separate parts — an indoor and an outdoor unit.

The indoor unit mounts on the wall inside your home, distributing air throughout the room. The outdoor compressor unit directs the refrigerant to and from the indoor unit.
