F**K off spammer

PS.
ANY one with A/C issues please take your car to a professional, where
leaky parts will be fixed, the system vacuumed and regased properply.

The websites BS do it yourself methods stuff the enviroment, can
easily damage parts in you A/C system and leave your wallet with a
massive hole in you wallet.
You have been warned.

A/C is kiddies play. Nothing about it is complex.

Kinda like brake boosters - the "expert" home handyperson
won't understand, or want to touch them.

Indeed. Almost as simple as an LPG fuel system. :-)

Yes, but the fecking big spring in a booster is dangerous. :-)

One thing I have noticed with folks who "recharge" their various AC systems
with cans, is the necessity to evacuate the air that has got in. Another
thing overlooked is old AC hoses which have hardened, and hence lose their
flexibility, continue to cause leaks as engine movement stresses connection
points, especially on older installs, such as York compressors.

The solution I've seen on a few cars from VIC recently is to use LPG
hoses for replacements in the A/C.

Absolutely, and another thing to consider is the
charge required. I've got an R12 system here that won't
be going R290 because of a number of issues. The volume
of R290 required.
is one.

Hoses aren't a major issue as you can either make up your own (hose
and fittings are readily available) or have them made up (Pirtek,
Enzed, etc). The old flare fittings (used on some R12 systems) are
getting hard to come by but you can get flare adaptors to use with the
standard O ring type fittings.

A sealed unit from a domestic fridge can be used as a vacuum pump,
although I've never tested one to see how good a vacuum they pull... I
did once know a fridge tech who never used anything else. The rough
way, though not recommended, is to flush the system with refrigerant.
It's not legal if using HCFC's -- not that it stops plenty of domestic
a/c installers from doing it that way.

Nor can you buy HCFC (R134A) in cans... or any other container if you
don't have a licence. They've long been banned here in Oz though it's
apparently still legal in USA. AFAIK hydrocarbon refrigerant is now
available in cans (Hychill HR12), which might also be a bit easier to
use than the other stuff (especially if you don't have any way of
weighing it for systems without a sight glass). :)
