A/C Refrigerant-out to the air?

I am still toying with the idea of removing the air conditioning from my '31 A coupe. I don't use it-it was on the coupe when I bought it and it really adds a lot of lines, bits and pieces to an exposed engine area.

Following some previous advice, I spoke today to the best area mechanic I know and asked him what to do. He basically said, well there are millions of cars slowly leaking refrigerant because no auto AC is really leakproof, so just have yours be one more, but a little quicker.

Now I am kind of concerned about the environment, I re-cycle, conserve when I can and try to reduce my waste,so I am not completely happy with this. However, his points made sense in that:
We don't know what's in the system-Freon or 134a, we don't know if it's contaminated or if it has ever had auto parts store boosters added. It seems the commercial mechanic's refrigerant extractors are very sensitive to the sealant that's added to OTC refrigerant recharges-it ruins their filters to the tune of $400-500.

So I can see why he doesn't want to take a chance on an old, unknown A/C system. Any suggestions short of cracking it open and letting out the gas? And in actuality, I don't know if it's fully loaded or empty. Thanks for the help.

There are testers that will tell you what refrigerant is in the system and if it's contaminated. R134 A will have larger connectors than R-12 and are threaded on the inside as opposed to on the outside on the R-12 fittings. To find out if there's refrigerant in the system just press one of the valve stems under the service port caps in quickly. If pressure is released you know there's something in the system. You won't release enough of anything to hurt.

A/c ?

If your "mechanic" knew anything about A/C he could tell just by looking at the systems fittings if it is 134 or 12 Freon,take it to someone that does A/C and have them evacuate the system via vacuum pump,they'll be glad to take your freon off your hands and recycle it.

This whole R-12 / hole in the ozone thing always gets my blood boiling.

The same tree huggers that told me my heavier than air R-12 was punching holes in the ozone layer by rising there on thermal currents tell me I can't use my push mower and I must take the bus because they produce ozone. Of course this ozone can't ride the thermal currents with the R-12. Go figure.

The bottom line is the tree huggers, the really serious ones, have an agenda. They don't want us to enjoy the fruits of our labors. They would prefer we freeze in the dark.

And the chemical companies rolled over on the R-12 issue as well. With good reason. R-12 had been around so long, it had become a commodity product. Low margin. Banning it and coming out with a new, higher margin product was great for them.

I think we have to be careful with what we do to the environment, but with some common sense. In your case, I think a shop that specializes in AC would use the proper equipment to drain your system for you. If you can't find one to do it, your 2 - 4 lbs. of R-12 isn't going to end the world. But you may want to check your local ordinances to make sure if you get caught you won't get into too much trouble.

The fittings will tell you only that the system is SUPPOSED to have R12 or R134 in it. It does not tell you if the system has any of the junk in it you can buy at auto parts stores.

Release it.........Us Canadians are glad about the Global warming......................

Seriously, an AC shop would charge very little to evacuate the system.

Just go by a mechanic shop, and ask them to evac your system. You will be doing your part, for the environment. It will only cost you about $30 to evac only.

I would not consider myself a "tree-hugger", but use some common sense. You can have that stuff evacuated relatively easilly. You can say that it is just one car, but if everyone says the same thing, they add up. I know a lot of people don't believe in the global warming, but look at the temperatures the last few years. I was in Oblong Illinois a couple of weeks ago. It was mid October and 85 degrees outside.

Also consider the fine for releasing that stuff. Is it worth the chance?

Aaron, your argument about the fine is valid. Your example of global warming is invalid.

Exactly!

http://www.weather.com/weather/wxcli...?climoMonth=10

The record highs for Oblong in October were all in the 80's and 90's with most of them being set in the 50's.
I refuse to use this of evidence of global cooling.

Just drive down this way and let it out. It'll latch onto the ozone put out by all these stinkin pine trees, and nobody'll notice. Heck, if we get lucky, maybe we won't have to use oxygenated fuel.
