Dual AC

I Have a 1985 Gmc conv Van With Dual Ac And it needs a retro fit to put new
freon in it ,and the chevy houses want about four hundred dollors to do
this,But here is my dallima we are on a fixed budget.so a friend told me i
could bye a conversion kit to do this my self from checker auto for about
60 dollors,but an ase certified mechanic says they will have to replace
both dryers and valves to convert this over.so my friend says to have it
evac and then bye the conversion kit and do it my self.Is this doable for
me.

You do not need to replaced dryers for a conversion but you do need
the vacum down the system. (No way around that) Why are you
converting? If you are low on freon even at totadys price you should
be able to get R12 replenished for a lot less than 400 bucks and
beside if you switch over to R134, cooling performance will degrade a
noticable amount because R134 has a lower heat content than R12 and a
different pressure curve too. New R134 system have different
compressors and bigger condensors and evaporators to make up for this
efficency loss you old R12 system does not. I would only convert to
R134 as a last resort as there are some other option out there for R12
systems that are better than R134 but all of them require system to be
vacumed down.

I'm not here to debate anybody but $400 does not sound like an
unreasonable price for a duel system. I had my 1983 Continental
Mark VI converted to R134 last year, at a Lincoln dealership.
They changed some seals, evacuated the system and refilled it
with R134 for $185 plus tax. It is still working fine a year
later. I too was told it would not be efficient, however I have
not noticed any deterioration in cooling ability. In fact it
apparent to cool down a hot car more quickly than does my 2205
Lincoln LS or my 2005 Mustang GT

Thx guys I was told they did away with r12 freon.we just bought this
conversion van and it sat for 9 years in a shed,And the air wont cool.so i
will go to checker today and bye a r12 kit.

thx snowman,were i live for some reason these garages want to tell me a lot
of money to change this system over wich aint bad as yall say.so I'll just
take it out of town to a big city and have them service it thx.loyd

so steve can i request to have a garage put R19 in it,we use this
conversion to take long rode trips out of our home state to see family in
az and ca.and its really hot on that az desert if you nkow what i mean.

IF you know how to recharge it you can get your 609 certificate online
for 20.00
Real easy to do just download the book and take the test.

Saw the question about R-19? Never heard of it.
Basically IF you want it to be serviced by any normal shop your choices
are R-134A or R-12. Most shops won't even hook onto a vehicle with any
of the blends in them.

Personally I'd just find a shop and have them vac it down, check for
leaks, recharge with R-12. Probably should have the compressor seals
replaced considering the year.
Should run about 150.00 or so plus the cost of the seal repair. Then you
would be right back to original condition. With a conversion van you
need all the cooling you can get. Especially if you have leather
interior. Mine has Dark blue exterior and Royal blue leather interior.
Let it set in the sun a bit and you could cook inside the beast.
