a/c leaking
I need some hel p troubleshooting my a/c. How do I go about looking for leaks in the system? Are there any specific areas I should be looking at? If I decide to convert to R134a, does the conversion kit come with all the o-rings so I can replace all the old ones?

They do sell kits
They sell dye kits that you can inject into your system that will help you find the leak.
I'm not sure if the o-rings come with the conversion kit or not, i'm not even sure if it's woth your trouble.
Once you find the leak, if your components are all still good once you get it recharged the a/c will work and keep working.
The only problem is r-12 can be very expensive, because it is no longer manufactured.
As much as I hate to say this,my suggestion is take it to someone who does a/c systems profesionaly. They have the right stuff to do it right.

What you wanna look for is all the fitting areas. What a leak will show is a greasy spot. The dye works well as stated by racer.
R-12 is running about 500.00 per 30lb jug of it. This is the only way i am able to get it.
My Father owns a HVAC wholesale house and that is about what he buys it for and can only get it in those size bottles. I know you can get smaller ones but need a license or someone that does to purchase it anymore. I can sell you a partial bottle but it is real tricky getting through the shipping companies
My opinion R-12 is the best but there is alternatives several of them. The thing to keep in mind is freon never runs out. If you have a tight system it will last forever but if there is a leak "then" you will run out. Good luck on this!

Any freon is an "oil magnet." If the freon leaks out, it will leave oil residue at the point of the leak. If you see an oily spot on a hose, cover it with a little dishwashing soap, and see if it blows bubbles. Look closely at the center of your clutch. That is where the shaft seal is, and if it leaks, you'll find oil residue in the center of your clutch. If you find and fix the leak, don't forget to add oil to your system when you charge it with freon.
