kestas ive considered the duracool option too but my vehicle is not exclusively non smoking

It may cool well but its illegal most places due to flamability...and just how well will it carry the oil...my understanding was while Propane and Butane woudl function as a refridgerant it can't carry the oil needed to lubricate the pump.

apparently "autofrost" is r406a.it is a drop in replacement for r12 with no oil compatibility issues.

But who determined that....the manufacturer (who has every motive to stretch the truth) or respected ndependent sources (with no motive to stretch the truth)....

To riterate for the 100th time! All alternative refrigerants are either flammable or a blend. R406a is a blend. The problems with blends are; the components leak at different rates requiring COMPLETE removal in the case of a minor leak instead of topping off, also they have trouble circulating lubricants to keep your compressor alive.

Additionally for the 100th time, each one of these alternative refrigerants are supposed to be recovered just like 12 or 134. Have you ever seen a recovery machine setup for anything other than 134 or 12? I haven't. These machines are expensive and no one is going to have one set up for every possible refrigerant, plus the EPA does not allow machines to be changed around. The EPA also requires fittings specific to the refrigerant. Have you ever seen any 406a fittings? I haven't and probably never will.

For the life of me, I can't understand the fixation people have that keep them from buying a refrigerant (R12) because it costs $15 per pound. People routinely spend HUNDRED$ of dollars to convert so that they can save maybe $30 on refrigerant. I guess there are just that many people that flunked third grade math.

Have a great day,

s that is a very valid question.my info comes from independant test.linkyehttp://www.refrigerantsales.com/

LarryBible is one of our resident experts.....

Like I said....look who is making the claims...its a place with financial motive to make those claims...becasue they sell it...Its also illegal to use in most states.

Refridgerant costs for the right stuff are not high enough to justify using anything but the right stuff.

Also be very wary of venders hawking their wares......Like the snake oil salesman of yesteryear they have every motive to say anything it takes to sell every bit they have....

R134 is more like $10 where I live. Have you actually seen it recently for $4 at WalMart?

Do you realize the cost to properly convert to R134 from R12 so that the system doesent disolve itself from the inside out from aacids formed within 2 years...is pricey and labor intensive.

And even a properly converted system will not cool as well on a 90 degree day as R12 will....There are more things to think about the just what the refrigerant costts...that is the cheap part of the equasion.

Yup, $4, on sale recently and now off sale the last time I looked. I expect it to get back down again as we get into hotter weather toward July and August.

230/8

$4 a can is big news. Where did you see it for that price?

dollars are not the issue for me.no shop in canada will touch r12 system.they insist on evacuation and swap to r134 before any leaktesting or repair.i am simply looking for the best alternative.the law is very strict here on r12.

I just bought R12 for $14.06 per pound, not per 12 oz. can, but $14.06 per full pound. Most a/c's take a little over 2 pounds. You do the math.

If you can find any 134 for $4 per pound in the last four weeks, I'll bet it will be gone or the price higher the next time you go back there. If you think you might have a need for 134 you better latch onto it.

Anyone paying $150 per pound in todays market is one of those people that P.T. Barnham talked about.

Have a great day,

Larry is correct. Just saw Dupont Suva 12oz can 134a at Autozone for $10.99. My 16oz can of R12 was $14 (134a is more than R12!) Hey Larry my Autozones do not rent a/c vacuum pumps, just the mity vac types.

Hey folks either stay with R12 or go with R134a, anything else is snake oil!

A sucker is born every minute.



R12 is $12-15/lb on ebay if you look about. 134A was $11/12oz from Dupont four days ago.
