Sometimes the term “Package” unit is confusing, but in this case we are referring to a self contained unit that comes pre – assembled. The differences between this and a window unit or PTAC are substantial. First, a package unit usually can cool and / or heat the entire home or building, and this system is connected to a ducting system, unlike the window unit or PTAC. If the unit also includes gas heating, they are sometimes referred to as a “gas pack.”

Package units sit outside the home on the ground or on the roof. In trying to identify this type of system, you won’t normally see copper tubes coming out of it to the house, but you could see ductwork, or a large boxed in area connecting the unit to the house that the ductwork runs through.
