Auto Air Conditioning & Heater Repair: Auto a. c., professional facility, freon

Question
My 1990 olds delta 35000 miles a.c. blows only warm air ,can a novice check the gas or add some without any special tools or gauges? Can I buy it at a auto supply store? Or how should I proceed?

Answer
If the system is LOW on FREON this indicates that there is a LEAK in the A/C system.

You need to get the leak fixed by a professional facility who has the necessary equipment to properly diagnose and repair the leak BEFORE you add additional freon.
