Id like to keep my AC instead of tossing it. I have a 91 crx that uses R12.

How much is the R134 conversion and what does it involve?

If its too much, I'll sell the system and get my rear quarter windows and hatch tinted and buy a cheapo windsheild sun shade for when im parked.

The 134a conversion is fairly easy, but you will need to take it to a shop. Then they will suck out what's left of the r12, probably replace the receiver/dryer, and fill the system with 134a. You should also have them check for leaks. R134 doesn't work nearly as well as R12 though, so if you can find a place that still has some r12 then you should go for it

 

you may need to change your compressure but not a 100% on that r 12 is the **** tho freeze 12

Don't think it is legal in the US but it works and is in use in Canada.

 

Honda is about 120.00 range. But this is what happens. they suck out R12 and as much oil as possible. They have to add the 134 fitting on top of the r12 ones since machine connections are different.
It is not a bad idea to replace the drier anytime the system is opened up but not neccessary.
Then fill with amount of R134 oil that was drained from R12. Charge and go.
I did this to my 91 accord wagon last year and A/C is good.

The deal with the different oils is the R12 oil will sit under the R134 oil so it will be at the bottom of the system.

= no worries mate

 

And what types of shops do this besides say a dealership? Never looked into this before, sorry.

 

Don't know I was working at a honda dealership at the time but I had a local guy I know suck the R12 out for me since we didn't have an R12 machine yet. I did 2 or 3 after mine.
Just about anybody with the equipment should take R12 and not charge you if you talk to them right. Since it is expensive and you are just giving it to them.

EXACTLY.

This is a VERY important point. Unless you are totally comfortable with the fact that you WILL lose cooling ability, don't convert to R134a. Because if you think that your A/C is going to work as well as it always has in the past, you have another thing coming. Keep in mind that the loss of cooling power will be most noticeable in situations that put the A/C under the most stress. These include VERY hot days and running the A/C without the vehicle moving.

I would have to agree with this. Although I never used A/C much I just wanted the convenience of R134a I did notice a loss in cooling at a stop.
