Is it a new or an old window unit? Assuming your looking to refill it I will assume it is an old window unit which most likely uses R-22 refrigerant.

For automobiles there are many but the two major ones are R-12 and R134a.. For the home there are various types of air conditioners like window air conditioner, split air conditioner, packaged air conditioner and central air conditioning system..... Most home systems use R-22 refrigerant but R-410a is also an increasingly used refrigerant known as PURON...................
You will need a set of refrigerant gauges, a tank of refrigerant and a refrigerant scale. You will also know technical knowledge of superheat and subcool and be EPA certified.

An air conditioner in a RV uses refrigerant to chill air passing over an evaporator coil. The most common refrigerant is Freon and is easily found in most autopart stores.
