I would strong suggest not converting to 134a like everyone else says
you should. The people at the shop want people to because they can make
MONEY off of it. Now I got screwed, and my A/C is never very cold. It's
only cold when you have been driving for a while, but when your in
sit-and-go traffic it's just very cool/warm air coming out.
Do this work yourself, and keep your R12. Trust me, unless it's not
very hot where you live, your want to keep your R12!
take it easy!
Your conversion was evidently not done correctly or you still have a
Here in hot, humid Central Florida I have seen hundreds of these conversions
on Hondas and they cool the car sufficiently.
The conversion parts are simple. All you need is the two valves (high side
and low side) replaced. Individual valves are usually available at a good
auto supply parts store such as Napa. Once your repair is done, if you do
have a leak, the system is evacuated and filled with R134a. Any future
repair will be reasonably cheaper considering the difference between R134a
There is no doubt that getting R12 refills is difficult and expensive, but
R134a definitely has limitations in an R12 system. I was talking to the head
mechanic in our company garage about conversions, and he gave me his
R134a needs a much larger condensor surface area and demands an electric
condensor fan (for the same reason). The R134a compressor and expansion
valve are also designed differently to match the differences. Since the 92
Accord has an electric condensor fan already, it might be satisfactory. The
$1100 conversion and compressor replacement (the compressor had seized) the
dealer did on our Volvo was totally professional and was never adequate. It
blows maybe 45 degree air on the freeway and maybe 60 degree air while
stopped in Phoenix traffic. Ya pays yer money and takes yer chances.
