A PAC (Packaged Air Conditioning) unit in HVAC refers to a self-contained system that houses all the components, such as the compressor, evaporator, and condenser, in a single casing. These units are typically installed outdoors and are connected to the building’s ductwork. PAC units are known for their space-saving design and are commonly used in commercial and industrial applications.
