Why PTAC Unit
A Packaged Terminal Air Conditioner (often abbreviated PTAC) is a type of self-contained heating and air conditioning system commonly found in hotels, motels, senior housing facilities, hospitals, condominiums, apartment buildings, add-on rooms & sunrooms. Many are designed to go through a wall, having vents and heat sinks both inside and outside.
PTAC units act much like a standard window or wall air conditioning unit but are meant for thru-the-wall installations. Besides providing you cooling comfort in the hot weather days of summer, PTAC units also provide you heat to warm your surroundings in the cold winter days.
