Split System

In Plain English

An HVAC system with separate indoor and outdoor components connected by refrigerant lines.

Definition

An HVAC system in which the refrigeration components are split between an indoor unit (air handler or evaporator coil) and an outdoor unit (condensing unit), connected by refrigerant piping. Split systems are the most common residential and light commercial HVAC configuration. They offer quieter indoor operation than packaged units because the noisy compressor and condenser fan are located outside.

Example

A 5-ton split system serves the executive office suite, with the air handler in the ceiling plenum and the condensing unit at grade.
