How are you supposed to “correctly” remove Freon from your original 1968 Air conditioner lines? I am at the stage to remove the compressor but am stumped on this process.
You are supposed to have a shop having a recovery system (which is basically a compressor driving into a container) suck all the R-12 out before anything is taken apart. I have certification for R-12 recycling procedures.
So if my car is on jack stands and I have begun removing engine parts. I am screwed?
I haven’t done it but my father had AC certification and his garage method was to evacuate an empty freon bottle with a vacuum pump. Then he would connect the pump to the system to be evacuated with the output side on the freon bottle. He would open the valves and let the vacuum in the bottle and the pressure in the system equalize, then turn on the pump to suck anything out of the system that he could. He would then shut the service valves remove the tank and pump, then slowly ope the service valve to the system letting air into it. Once it was at atmospheric pressure we took everything apart.
Yep, this is the way. You can use a refrigeration compressor (like from a refrigerator for instance) as the vacuum pump. Low side to what you are evacuating, high side to container.
