The benefits of Package Units start with understanding the term "Package Units". A package unit is a self contained unit that comes preassembled from the factory with all the major components in one cabinet.
The differences between this and a window unit or a PTAC unit are substantial. First, a package unit can cool and or heat the entire home or building through a ducting system. A window unit or PTAC is meant to be used as a single room spot cooler.
Package units sit outside the home on the ground or on the roof. They can be ordered as cooling only or combination cooling and heating systems. Many options can be ordered and installed at the factory based on the customers needs.
