R12 refrigerant conversion for pre-1993 vehicles

If your car was manufactured prior to 1993 then it will contain a CFC refrigerant called R12.  In May 1995, scientists discovered the depletion of the Ozone layer due to CFCs and in 1997 the ‘Montreal Protocol’ determined CFC refrigerants be phased out.

If you are not sure which refrigerant your vehicle uses, don’t panic, there is an easy way to tell the difference. The car manufacturers decided to change the design of the a/c service ports when R134a was introduced to highlight the difference.

Car air conditioning systems using R12 refrigerant are still allowed to operate but when serviced, the CFC refrigerant must be recovered and disposed of, and the system re-charged with an alternative refrigerant.

For the car owner, having your pre-1993 vehicle converted to non-CFC refrigerant means you can once again enjoy the benefits of air conditioning all year round.

- 1978 Rolls Royce
- 1984 Porsche 928s
- 1989 Audi 200 turbo
