A few weeks ago, just before a trip across the Mojave Desert, my old
compressor on my car AC system went bad. As I replaced it, I thought I
had two options -- stay with the old ozone-depleting refrigerant, R-12,
or change over my system to hoses and fittings that would handle the
replacement refrigerant R-134 at an expense of about $800.
A third option, using the new HC-12A refrigerant, was brought to my
attention by my AC service person. I had not heard of it before, and so
called the distributor to find out more about this product.
After learning that it is a truly “drop-in” replacement, is completely
ozone-safe, has been passed by the EPA, and has been extensively tested,
I had HC-12A put in -- no conversion was necessary; they just evacuated
my existing system and charged it with HC-12A.
It has been two months since my charge, and so far I could not be
happier with the results. The AC cools better than it ever did before,
holding at 35-40 degrees F. during the cooling cycle; HC-12A is
inexpensive; and since less HC-12A is needed in the system than the old
R-12, the compressor runs quieter, doesn’t work as hard, and puts less
of a load on the engine.
I cannot attest to the long term results with the product, but at this
point I recommend this new refrigerant to those who are ready to change
over from R-12 to an ozone-friendly product.
For more information on HC-12A, contact the distributor:

I suppose neither you nor your mechanic realizes that the EPA has not
certified a single replacement (there are several) for use in _mobile_ A/C
applications. If you have an air-conditioned trailer, you can legally use a
replacement, but if your R-12 car needs a charge, your two legal choices are
more R-12 (as long as supplies hold out), or roll the windows down.
The EPA can fine you $25,000 for using a non-approved alternative, with a
$10,000 reward for whoever turns you in.
Yet another example of our fine government. For sale to the highest bidder.

The Arizona legislature recently passed a bill allowing production and
transport of R-12 within the states borders, in direct violation of federal
mandate. Way to go Arizona!

There are two EPA "approved" substitutes (besides R-134a) for
"automotive retrofit"
Dupont MP52 (R-401C).. blend of R-124/R-152a/R-22, needs
"barrier" hoses, XH9 desiccant in the drier, and alkylbenzene
oil (80% of oil changed). Alkylbenzene oil is "stable"
unlike PAG (for R-134a) in systems which previously had R-12
in them. MP-52 would be a much better choice than R-134a.
Intermagnetics "FRIGC"..(FR-12 ?)
This is just R-134a with a little Butane thrown in to carry the
oil (no percentages released) and some R-124 to control flammability.
Needs barrier hoses, works ok in "mineral oil" (R12 oils)

I am not sure but I think this is the replacement refigerant that
is made up of a large amount of propane. If that is the case you had
best check your insurance for a large number of them will not insure
the car in the event it explodes in an accident..
could be wrong but it might be worth a check..
