Freon (R-12) is way too expensive as it is no longer in production. Have it converted to use R-134a. I suggest a visit to a professional A/C shop as the fact that you need to add refrigerant indicates you have a leak that needs repairing. It is illegal to add refrigerant to a system with a leak without first repairing the leak.
R-12 which is very dangerous. And they don't make it anymore. You need to have what freon is left in it flushed out and then get the kit to switch it over to be able to use 134A. You can get the kit and freon at walmart or pepboys or autozone or whatever local parts store you use.
It could need freon. and you can do it most auto part stores carry it so does walmart
The 1992 Toyota Camry air conditioning system has a Freon capacity of 5.1 pounds. In most cases recharging the air conditioning system will take much less than the system capacity.
Either low on freon or the low pressure switch is bad. You are gonna have to put a set of gauges on it. Usually this happens when the freon leaks out of the system. If there is not enough freon in the system, the low pressure switch keeps the compressor from coming on and being burned up.
It turns out that if there is no freon in the system, the computer puts out errors which in turn shut off the power to AC. Refill the freon and clear the errors either by tech or diconnect the batter for few minutes :) Learnin the hard way
Was built for R12, should be converted to R134a

If you're not familiar with the A/C system, then you need to take it to a mechanic. You can damage your A/C system and even get hurt if you don't know what you're doing.
If its been recently charged there maybe moisture in the system.
