Check the information sticker on you Air Conditioner It will tell you the Voltage, cycle, Amperes, and B.T.U.
If the sticker is not located on the outside of the Unit, You may find this sticker on the inside of the unit, removing the front cover and air filter.
The Gage of wire too use:
12 Gage wire will carry safely 15 amps and it's suggested that you do not exceed that size breaker.
Most 220 Volt Air Conditioners of that size (18,000 B.T.U# will draw around 12 Amps or less, depending on condition #age) of the unit, older units will draw considerably more.
Hope this helps answer your question...
