My 1991 Sapphire has Air Con which was fitted when it was a few months old by Alpinair in Middlesex. Its not working & was going to get it regassed & check for leaks to see if its worth bothering with,if its too costly to repair i was going to remove it. On the slam panel it says R12 refrigerant on the Alpinair plate, now i thought this was an old type gas & R134a is used now, can i still get it gassed or is R12 not available or can i just have R134a put in ?

Cheers Simon.
