A PTAC, or Packaged Terminal Air Conditioner, is a self-contained heating and air conditioning system that is commonly found in commercial spaces such as hotels, motels, senior housing facilities, hospitals, condominiums, and apartment buildings. It is a ductless, through-the-wall heating and cooling system that can be used in typical residential environments as well. PTACs are compact in size, ranging from 42”x16” to 36”x15”, and are designed to heat or cool a single living space using only electricity (with resistive and/or heat pump heating) . They are also equipped with a heating function, making them ideal for year-round use. PTACs are a cost-effective choice for heating or cooling individual rooms in a home or commercial buildings like hotels, apartments, or senior living facilities. Some benefits of PTACs include:

• Compact size
• Year-round use
• Cost savings on power bills
• Individual temperature control for each room
• Easy installation and lack of ductwork

PTACs are commonly installed in window walls and masonry walls, and their installation typically requires louvers, a metal sleeve, a heating coil, the PTAC itself, and room enclosure.
