PTAC Units
A PTAC unit — packaged terminal air conditioner — is the self-contained heating and cooling unit you see under the window in hotel rooms, apartments, senior housing and offices. Most install through an exterior wall in a standard 42-inch sleeve, and most models heat as well as cool, with an electric heat strip or a heat pump. A PTAC air conditioner typically runs on 208/230 volts from a dedicated receptacle. When you replace one, match the sleeve, the voltage and amperage, and the heat type, then compare BTU capacity, corrosion protection for coastal buildings, and the controls.
