Refrigerant is used because it evaporates at a low temperature, and condenses at a higher temperature. Refrigerant is any element that can be boiled into a vapor, and then compressed into a liquid. This means that even water is a refrigerant (and indeed, we take advantage of its cooling properties all the time.) However, other elements that are used specifically for refrigerant have a lower boiling point (or temperature at which they evaporate) and condense at a higher temperature. This gives us a faster cooling effect which gives us the chill of an air conditioner.
Almost all air conditioners today use a freon refrigerant called R-134A, which replaced the old R-12 when we discovered how R-12 hurt the ozone layer with CFC byproducts.
Maintaining Your Air Conditioning System
Many professionals recommend having your A/C checked every year. An A/C checkup can ensure the efficiency of your car, since running the air conditioner does take energy from the engine and cost you extra gas. Yearly checks can identify leaks early, which makes them easier and cheaper to fix, and can prevent one broken part from compromising the whole air conditioning system.
