The air conditioning gas (which I believe is Freon, although it may be spelled differently) is highly dangerous stuff and I don't think it would be wise to try to remove it yourself, unless you are trained to do so and have the correct containers to store it in. I've heard of people losing fingers whilst draining that stuff, so I'd leave it to the professionals.

Don't know WTF this guys talking about but crack a line and wait 30-45 seconds, all of a sudden you have no more Freon. I guess if you get scared by the "hiss" and the hood falls down across your hands....

Ofcourse I don't see the logic in taking apart a perfectly good system, but to each his own.

you could always use a long screwdriver, and press in the shrader valve.

keep clear though because that stuff will be cold enough to give you frostbite.


that will remove all the stuff under pressure.


to really empty the system so you can refill it, you need a vac pump

My only peeve about dumping a good R12 system is the 90 bucks lost in the evac.

I'm really suprised an AC place wouldn't evac it for free, due to the cost of R12.

Why contribute to the pollution problems we have right now? c'mon, just fork up the cash, or the gas to drive to a shop, and have it evac'd by a pro.

when high pressure gas expands, its cools rapidly and ALOT.

in other words, touch the air coming out and you will freeze your hand.

hm... maybe my A/C had some different stuff in it. I was looking around to see what all I could rip out, and accidently opened it (I was going to do that anyway, but wasn't ready at the moment) and the blast hit me in the face... it felt just like normal air out of a tire or something... I'm still here, both eyes, both eyebrows

I just let it "his" for like 30 minutes or so, then yanked it all out :hail:

Seems pretty obvious you don't know what I'm talking about

Maybe when you've taken people to hospital with severe injuries caused purely by a lack of experience with air conditioning equipment, you'll have more of an understanding.

yes, the A/C worked, but I got even worse MPG when I ran it, when the car wasn't moving, it made horrible noises.

Well, the blast of air was REAL strong, I didn't mean to compare the strength to a tire, just that it didn't "burn" me or irritate my face.


sorry about the confusion :-)

seriously, just wait till you can get it to a shop. they will collect it for FREE. please, dont pollute any more than you have to. yes, i dont have a smog pump and all that stuff, but come on, dumping r-12 into the air? thats just ignorant.

Lol....25 + years ago, long before anyone was telling us R-12 was "bad", it was common practice to crack the fitting off the compressor, wait a 1/2 minute or so as it left the system, then change what was needed, pump it down, fill it up, and go on our way.

If someone was doofus enough to burn thier hands, etc in the process, they shouldn't have a wrench in thier hands.

Side note about R12, always though it was heavier than air...seems it would sink to the ground, rather than dissolve in the air ...I dunno.

Oh, and for the enviromentalist in the group that was me digging holes next to fence post's to dump the oil changes in.: ... posts never rotted.

well dont call me an environmentalist yet....hell i dont even dig holes for my oil changes . Actually in the off-road community (read: me) taking care of these things is a big concern. see, you guys dont know what its like to have to fight to keep your "roads" from being taken away by the tree-hugging environmentalists. every little wrong we do, gets multiplied 100x by those fawkers. so i guess it just makes me naturally concerned

Whatever your opinion on how bad R-12 is, I for one am not willing to advise someone I've never met to "crack open a line" when it contains a potentially harmful substance, both to the environment and to him. You say someone has to be a "doofus" to burn themselves with it, what makes you so sure the guy who started the thread isn't a doofus? I'm sure you're not, raffi, but still....

You know, once upon a time we were told smoking was good for us. 25 years ago isn't really relative anymore.

Water is heavier than air. Do you get wet when you look down a hose and turn it on?
