What is a Package System?

A single package system is a year-round comfort system in which all equipment is self-contained in one unit and installed outdoors, typically on a concrete slab or other platform.

In the summer, a single package system provides the comfort of central air conditioning. During the colder moths, the unit provides heat. Essentially, it is an air conditioner and heating unit in a single package, hence the name.

The efficiency of single packages are rated using SEER (for cooling efficiency), AFUE% (for gas heating efficiency) and HSPF (for heat pump efficiency). Ductwork is required to transfer the heated or cooled air throughout the home.
