Packaged units are comprised of a compressor, condensing coil with a cooling fan, and an evaporator coil with a blower fan. Packaged units function much the same as a traditional split system, encompassing all components in one cabinet versus two different ones. Typically the cabinet is mounted on the exterior of a building then ducts deliver air to the building or home and return air to the machine.
The most common application for package units are mobile homes and rooftop mounted systems. In some cases, package units are a perfect alternative to split systems when it is impractical to install equipment in attics or in closets where space is limited.
Trane package units are available in straight cool and heat pump models and in various levels of energy efficiency.
