This is a healthy debate about refrigerants.

Freeze 12 is NOT illegal in 18 states.

Quote from EPA website:
"The following 18 states ban the use of flammable refrigerants such as HC-12aŽ and DURACOOL 12aŽ in motor vehicle air conditioning, regardless of the original refrigerant: Arkansas, Arizona, Connecticut, Florida, Idaho, Indiana, Iowa, Kansas, Louisiana, Maryland, North Dakota, Oklahoma, Texas, Utah, Virginia, Wisconsin, Washington, and the District of Columbia."

Only hydrocarbons-refrigerants are illegal in those 18 states.

Freeze 12 is a LEGAL replacement for R12, by EPA regulations (all states). IT IS NOT A "SNAKE OIL - REFRIGERANT". It is a blend.

Sometimes we let our personal feelings/opinions get in the way, and call things something they are not.

It is LEGAL to use HYDROCARBON refrigerants in North Carolina. Providing the system was a 134a before the conversion (by EPA standards)

It is ILLEGAL to vent ANY refrigerant into the atmosphere.

Those are the facts, debate about which is better or more or less dangerous is another story.
