Packaged Unit

In Plain English

An all-in-one HVAC unit containing both the heating and cooling equipment in one outdoor cabinet.

Definition

A self-contained HVAC unit in which all components—compressor, condenser, evaporator, air handler, controls, and optional heating—are housed in a single weatherproof cabinet. Packaged units are typically installed on rooftops or ground pads adjacent to the building. They are common in light commercial applications because they simplify installation and service access.

Example

Six 10-ton packaged rooftop units serve the retail store, with each unit connected to the interior ductwork through roof curbs.
