a/c removal question

dave 911 · dave 911's Garage

I'm planning on removing the a/c system from my car (76 911S, stock). I haven't run my a/c in more than 10 years due to it blowing warm air back then, and really not needing it. What are the chances that there is freon left in the system? Am I ok disconnecting it on my own?

I've done my homework and read all the threads related to a/c removal, and saw reference in one of them to having the freon system evacuated, but am hoping that it's all gone/leaked out by now.

thx

i took my 83 into a professional to have the freon caught/removed and the tech told me it was a waste of time based on the tiny amount that was left. he was a decent guy and did not charge me for his time.

The port on the compressor where the gauges are hooked up has a valve just like a tire valve. Just press in the center of the valve and listen. If there is any freon left it will hiss just like a tire. Do it at arms length. You don't want freon in the eyes.

I removed mine and there was nothing left in it either.........chances are, if it hasn't been converted or meticulously maintained ,and charged over the years, it is probably empty.

+1 nothing in the system when I removed mine. And one summer later, I don't regret it's absence.

I have an '85, considerably younger car...

I did the very same test, used a long screwdriver (and gloves and safety goggles) and gave the valve a very slight push. I figured if there was anything in it, the hiss would be obvious and I would then take it to a shop. As it turned out, my system was COMPLETELY empty.
