A packaged terminal air conditioner (commonly referred to as a PTAC) is a compact, self-contained air conditioning and heating unit that is most commonly used to control the temperature of a single room or living space. The units are self-contained, which means that they will only heat or cool the area where they are installed. As with most air conditioning units, PTAC units are designed to deliver cool and warm air into a room or living space. The efficiency at which these units operate and the on-demand heating and cooling they provide for single rooms is an excellent fit for applications in the hospitality industry such as hotels, motels and resorts. These PTAC units are also commonly used in apartment buildings, office buildings, university dormitories and many older buildings.

The uses for PTAC units continue to grow as more people look to take advantage of the energy efficiency and simple installation that these units provide. New applications include residential use; PTAC’s can be installed in new home additions and sunrooms where it is too expensive or difficult to extend existing ductwork.
