One "lights" the halide torch and it burns a blue flame. While the flame is burning blue, one uses a "sniffer" tube to probe for a chloroflurocarbon leak, (older style, ozone depleating refrigerant). The sniffer tube sucks in the leak and causes the flame to turn a greenish color due to the burning of the refrigerant. Thus one has now detected a leak. There are also other methods available for detecting a leak ie. soap bubbles, dyes, and electronic leak detectors.
Well I've seen ultraviolet reactive refrigerant that will indicate leaks, when a UV light is shinned on it.
If you are having to add refrigerant, then this means you have a leak, and you will be adding refrigerant again in a few months. It is illegal to add refrigerant to a system with a leak without first repairing the leak. So, my advice is to take it to a professional and have the leak repaired and refrigerant added with the proper equipment, which you do not have.
most modern electronic leak detectors these days can detect up to 0.05oz/y which equals to roughly 1.5grams/year Check for brands such as Inficon, Fieldpiece, Yellowjacket, Bacharach, CPS. Most of their leak detectors sensitivity vary from 0.1oz/y to 0.05oz/y

You don't. The 2000 Saturn refrigerant is not Freon R12 it contains R134a. Add it at the Low pressure port. You have a leak or it would not be necessary to add refrigerant. It is illegal to add refrigerant to a system with a leak without first repairing the leak. Take it to a professional and have the leak fixed.
If this is not a heatpump, the problem is likely a low refrigerant charge. Have a service technician check the pressures and also perform a leak search. If they only add refrigerant and do not perform a leak search you are not getting your money's worth.
First off if it is low of refrigerant then it has a leak. It is illegal to add refrigerant to a A/C system without first repairing the leak. You have neither the tools nor the skill to repair the leak, and to add the correct amount of refrigerant. Take it to a professional shop with the proper equipment and knowledge to repair the system correctly.
There is nothing you can do to prevent a leak from occurring.
it contains no Freon. It contains R134a refrigerant. If it need refrigerant that means you have a leak. It is illegal to add refrigerant without first repairing the leak. Seek professional help with the repair first.
There is no Freon in a 1997 Honda Accord. It contains R134a refrigerant. If it is low of refrigerant you have a leak. It is illegal to add refrigerant to any system with a leak without first repairing the leak. The professional who repairs the leak will recharge the system and check to make sure there is sufficient oil in the system. Not a repair for a novice.
