Packaged Terminal Air-Conditioners (PTAC)


Program Scope

The certification program includes packaged terminal air-conditioners as defined below.

A packaged terminal air conditioner consists of a wall sleeve and a separate encased combination of heating and cooling assemblies intended for mounting through the wall. It includes refrigeration components, separate outdoor louvers, forced ventilation, and heating availability by hot water, steam, or electric resistance.

Models designated as a “cooling only” unit may not include heating elements if the physical characteristics and arrangement of the refrigeration system are identical to models with heating availability.

This program applies to 50 and 60 Hz Production Models of New Construction PTAC. A new construction unit is a unit with sleeve dimensions of at least 16 in. high and/or at least 42 in. wide, as defined by ASHRAE Standard 90.1.
