Selling disposable cans of refrigerant to the public is not only very
dangerous to them, but, they do not have the expertise on how to
properly charge a cars a/c system. You dont just 'fill er up' with freon
; it has to be accurately measured in and you have to know what you are
doing . Youre doing a disservice to the public , albiet making a profit
doing so.

So I sure can not comment on it or the above reply...

I can tell you a bunch of us older farts used to buy 75 cent cans of
R12 at the local Auto Zones/Pep Boys etc and just filling "her" up so
to speak...

As long as you made dang sure the can stayed upright, worked just fine.

Still have a couple of cans on the shelf.
Regrettably, I didn't buy a large tank of R12
when Costco had it on sale, for "export to
Mexico."

My a/c guy is still peddling 'recycled' R12;
however the price is getting fierce.

I see mixed reports on FR-12 conversion --
any experience here??

REPLY: Its a pure guess unless your cars a/c system had a liquid line
sight-glass indicator whereby you would add refrigerant until all the
bubbles in the sight-glass went away thereby guaranteeing a full head of
liquid to the evaporators metering device ; but , manufacturers did
away with sight-glass indicators to save money and so Joe Public would
have to take it in to the respective Manufacturers Dealership to have it
properly recharged.

There's always somebody wanting to tell us not to service our own
airconditioners, but plenty of us are still doing it.
Anyone who wants to can take a test, pay a fee and become certified.

I bought the manifold gauges and vacuum pump on Ebay, very reasonably priced
I think the gauges were about $40 and the used vacuum pump was about $80,
incl. shipping. I needed both R-12 and R-134a gauges as I have vehicles of
both varieties. A little research on the Net was all I needed to get the
info like correct pressures, recommended oil (closed ended-refers to the
molecule), etc. and since having all this I've worked on about six different
cars and home A/C units too, I've probably saved at least $600 in service
charges so far. There's this clever inexpensive device that injects the oil
without adding any air or breaking open the system once under vacuum. There
is also a flush solution and 'gun' you can buy to 'pressure wash' the inside
of the system works great if you have an air compressor. And one can buy
R-12 on Ebay without a license if you send the seller a statement saying you
are buying it for re-sale.
