short answer: Only people with and EPA certification may purchase R22 and/or R410A refrigerants.
Air conditioner refrigerants, such as the widely used Freon, are not considered to be environmentally friendly substances at all. They are corrosive to organic material and highly toxic if consumed by living things, and should be kept out of reach when not in use.
There are a number of different refrigerants used - typically, CFCs were used in older AC systems, and HFCs are much more common now. Many people refer to all refrigerants as Freon - this is a misnomer. Freon is a trademark name for a series of CFC and HFC refrigerants manufactured by DuPont.
Refrigerant compatibility refers to different types of refrigerant being compatible. Not all air conditioners use the same type of refrigerant and not all refrigerants are compatible in every air conditioner.
Most refrigerants are heavier than air. Because of this, they can displace air and cause someone to suffocate.
Natural refrigerants - ammonia, hydrocarbons, carbon dioxide, water, air; HFC's
