As an addendum to this, try to find a shop that will do a free recheck of the system integrity a few weeks later. Make sure that you run your a/c as much as possible in the interim. this will help them determine whether or not any leaks are present in the system. I recently had my A/C system (87 Monte Carlo) serviced and recharged with 3.5 pds of r12 freon and will be bringing it back this week for the recheck. I certainly don't want to be caught down south without A/C! OH NO! See you all at the show. Jeff Chabotte http://www.88-mph.com
