Thanks for the input everyone.
I'm one of those who is too dumb to know if climate change is man-made or not, but thinks I'd feel even dumber if it turns out that we could have made a difference and we chose not to.. so am trying to do this right.
I found a Red-Tec tester for 3 bucks that you use on the low-side port to check for proper oil in the coolant... figured it was a safe way to sample the system.. got a very tiny psssst and then nothing.
So, if the low pressure side is empty is it safe to assume the hi-pressure side is empty as well ?? OK to disassemble ?? I'm thinking the hi-pressure side is only high when the compressor is running ??

yep if the low pressure side is empty then the high side is as well. although when the system is running the low side can be 20 psi and the high side can be about 150-300-ish. that high pressure can take a little while to equalize... i would estimate at about 10-20 minutes.
the ozone layer protects the earth in that it blocks a lot of the harmful radiation from the sun. now with the old refrigerant, it actually destroys the ozone, letting more radiation from the sun in. this is probably the main reason for a lot of the skin cancers and the earth heating up. r134a doesn't contain any ozone depleting gas (or so they say) and besides the hydrocarbon stuff, theres some new refrigerants available mostly for industrial use.
so if its like non ozone depleting like they say, then there should be no problem with releasing it to the atmosphere... just don't let anyone see you do it. R12 is a different story though...
you can just get two cans of duracool... they already come with oil mixed in. you just need to shake the cans like crazy to make sure the oil gets in the system. that way you don't need to worry about low oil situations.
