how much r-12 does the 7 take (lbs)?

 

don't know. Why don't you just have it converted to 134 ?

 

isnt it bad for the system?

 

craps $70 dollers a lb. wow. 4 cans is what it takes. how much is 134

 

******* CHEAP.

 

If you didn't keep your location a secret, someone might be able to help. I have lots of R-12.

 

That, and you have to be certified to handle R-12. They won't/shouldn't sell R-12 to anyone unless they flash their card. You might wanna go ahead and get the adapters to convert to R-134. Plus 134 is a TON cheaper.

 

Freeze 12 is your friend.
1.5 pounds should do the trick on the seven

 

Well that was helpful!

Here is a price comparison for bulk purchases.

Here are some R134a supplies on JC Whitney.

Here is a related thread, SAE has declared a worldwide shortage of R134a so prices will be going up:

I got some last winter for $12. a can, but now its summer$.
You can take an online, open book test (very easy) $20., to get your cert to buy.
134a is like $7. a can at Walmart.
Wheres a good source for freeze-12, and how much is it?

 

ok this may be a bad question but why do i need a license for r-12....
i only ask because i was screwing around with my ac compressor and air started leaking out of it....and made my throat numb, went away though.
I know nothing about a/c crap

 

You need a license because the EPA is trying(not very hard) to make sure you know enough not to vent it into atmosphere.
By having this license, you can be fined thousands for doing so.

There should be no air in the system, you released and breathed refrigerant.
I don't believe there are any lasting ill effects from that.
You can get frostbite if the liquid form gets on your skin, not hard to do btw.

You should take some time to learn more, or get someone to help you.

 

well it was far from cold, and i found a place to do the work but that ***** expensive

 

Okay, BREATHING "Freon" is not necessarily deadly, but it's not exactly safe for human consumption, either
As soon as the refridgerant leaves the system, it is depressurized, and therefore becomes liquid. There is a mild risk of frostbite ANY time you see refridgerant escaping, so be a bit careful, please.

The cert., obtained at www.ase.com (refridgerant recovery recycling or something like that) costs $13 by Credit Card (Check Card) and is invaluable if you don't plan on converting to R134 A.

"Freon" will also do VERY weird things to paint! Be CAREFUL venting that. If someone who knows their **** was watching, they could've reported you to the EPA, and fined you, certification or not!

FREEZE 12 is obtained at any refridgerant supply store/depot, and is around the same price as R134, give or take ten percent of the price or so depending on your area.

It is a DIRECT DROP IN for R12 systems. You don't even need to get 'barrier hoses,' although it IS very suggestable.

One word of advice: It's got some CFC's in there, so, therefore, it WILL require the certification.

 

Damn, never take your A/C system to a tech!
If I'm right, you're getting charged from $300 up?

 

First of all, when any kind of refrigerant leaks and becomes depressurized, it becomes a GAS, not a liquid. Its a liquid under pressure. Propane does the same thing. Thats why you can shake a propane cylinder and hear it sloshing, yet its a gas when it comes out because its a gas at atmospheric pressure and a liquid under high pressure.

Second, you need to be certified to buy any kind of refrigerant with CFC's in it. This goes for R-12, R134, and Freeze-12. I would highly suggest taking your car to a cerified mechanic that can work on A/C systems and has the tools to do so PROPERLY. The A/C system on any car is not to be tampered with by amatures. In no way should you ever touch anything or remove anything unless you know for sure it is fully discharged.

Sure, A/C work is expensive, but its worth it to have the work done by a pro.

 

Yeah, that's what I meant How embarrassing

R134 does NOT require a liscense to buy. That could be a misconception, though, as you are in Canada, which obviously has different laws.

If you KNOW that you just need a refridgerant refill, just do it yourself! There is NO reason to pay the exorbant rates that your local A/C guy will charge, unless you live in My area

BTW, you will probably need a vacuum as well, if you 'unsealed' the system.

 

My station wagon's a/c was R-12, but the charge was dead, so it was gonna cost me $150, but r-12 is worth it, but i was looking at freeze 12, some people say it works, for like a quick fix if your gonna sell your car and you don't wanna go through all the hassle of converting, or paying for a recharge, but in the long run, most of my friends complain because it kills their compressor and seals.

even though R-12 is expensive, it's still better than 134a, colder and more efficient. just as long as you make sure all your hoses are in good condition, and there's no leaks. Also if you run your A/C in the wintertime like maybe once a week for 2 minutes, it will prevent leakage, and for the $150-$175, you'll be good for a few years.

 

Fishbulb speaks the truth.

Freeze will last you a while, but it is known too. . . . um, deteriorate. It doesn't last forever like other refridgerants. It shouldn't kill the compressor and seals, though, unless they were already in poor condition.

R-12 isn't expensive, it's EXTREMELY expensive. Not worth it anymore to use it, even though it STILL has the best cooling capacity of all the current fridgers on the market.

"Freon" should last FOREVER, as long as your system remains sealed. Run the A/C in the winter, like Fishbulb said. The leakage that would come from this is worn seals (settled in to much), and that could also lead to a fried compressor.

For the $150 or so charge, you shouldn't be good for a few YEARS, you should be good FOREVER. ANYTIME you open your system, you should replace the receiver dryer as well, and the original poster seems to have opened his system.

 

any r134A converted system will cool like CRAP... You need a higher capacity system for r134A to work well at all

you can still get r12 for dirt cheap in canada! If your close to the border, then make a trip and get your a/c recharged!

 

i live in pheonix so they pretty much rape you i think ill hang on another month or so

 

[QUOTE=85rotarypower]First of all, when any kind of refrigerant leaks and becomes depressurized, it becomes a GAS, not a liquid.

Thats true, but its not instantaneous. It depends on the size of the opening, or volume. If it comes out fast enough it can get a surface wet, and very cold, if only for a split second, or longer if the source continues. The valve on the propane cylinder is designed to keep the flow minimized.
Also, if you open the top of an upright can, or an ac system, sure gas will come out, but try the bottom, where the liquid is at.

dirty86, theres an ac place in Phoenix I've bought stuff from, they have a forum, and I believe they have a shop, they seem very fair.
