I'm faced with replacing my A.C. unit due to oil leaks from the compressor.
QUESTION: Is this the time to install R-134 due to the high price of R-12
and the future availability of R-12?

Any suggestions?

Bob:

NAPA, for one, will have a replacement A-6 compressor for ~ $100.00.

If you do go to R-134a, you should plan to also replace your system hoses (~
$200.00 from Cinnabar) as well as the must do dryer change. If you have
Cinnabar's back issue newsletters, there was an article in one of them
detailing why the hose change is necessary (i. e. to prevent refrigerant
leakage), since the new refrigerant molecules are smaller and will otherwise
penetrate the hose sidewalls in time. I know one coach owner who had a
local (FL) A/C service shop make up the new hoses at a much more reasonable
cost - ~ $75.00.

There are also a lot of claims that R-134a has a reduced cooling capacity
vs. R-12 refrigerant. I've also seen a few claiming equivalency.

I opted to use an alternative refrigerant called AutoFrost, obtained from
Monroe Air Products in Bloomington IN, when I replaced my compressor in
1996.

Bob,

I would say no, Buy a new compressor head south to the Mexican border where
you can not only buy and have R12 charged curb side on the main streets but
one can have AC Service under most large trees from a mechanic. (There is no
evacuation done except to just release in the air.) If you make several
trips across the border having your system charged and drained into your own
canisters you will have enough R12 left to top off the system for a few
years

If you are really brave you can just smuggle the individual can across .

Thom:

A-6 is the designation of the original type compressor used in the coach and
also used in GM 70s vehicles. Later, 80s GM vehicles used a compressor,
designated A-4, which is much shorter in length, but larger in diameter.

Ask any parts place for an A-6 A/C compressor and they'll know what you're
talking about.

Now there is an excuse for me to make that big trip out West in my GMC.
I've always wanted to go Mexico in a motorhome. So when the A/C stops
running I'm heading south of the border!! :-)

Do I detect that you are skeptical????
As I said below, I've been running AutoFrost in my A-6 compressor since 1996
and I know someone who just converted to R-134a when he replaced his
compressor with another type A-6.

Finally I get to contribute something useful.

"A-6" Stands for Axial 6 cylinder. This compressor has 6 cylinders arranged
axially. It is extremely efficient and reliable. If you ever tear one down
or look at an exploded drawing you will understand why my had is off to the
designer. There oughta be a museum for such elegant designs. And yes it will
accept the "modern" refrigerants just fine, though you will need to change
to compatible oil.

It was replaced starting in the mid 70's on smaller GM cars and gradually on
just about everything by a compressor designated "R-4" which meant Radial 4
cylinder. Because it is a radial design...kinda like a Pratt&Whitney
airplane engine...it is shorter but somewhat larger in diameter. Both are of
nearly the same displacement. The early R-4's were somewhat unreliable but
later units seem to be holding up well.

A little trivia question...any of you guys ever give any thought to why a
radial engine Always has an odd number of cylinders?

Travis

BTW, do you suppose it is so hot in Mexico because of the ozone hole caused
by those guys releasing R12 into the atmosphere there?

Thank!! Autozone had the A6 on the shelf for $59.95 with a $10 core charge.
Now, while I'm at it, I should probably replace the 'Receiver/dryer'
before filling up the system with R12. Anyone have a common part number
for that part of the system?? (ps I have a 35 lb R12 container that I
purchased before that imposed 'Ban' on it.)
