If you have an air conditioning system that is older than 15 years, chances are that it uses R-22 refrigerant. And, the manufacturing and sale of new R-22 refrigerant is NO LONGER ALLOWED in the US. If you need a coolant charge this year, the service bill may be as high as $1,000. If you need a coolant charge next year, you are out of luck and will be faced with an AC system upgrade!  This is a mandated environmental impact directive issued by the United States government.
