A/C Conversion

[93 Q-SHIP]

My '93 Q45t is still running R12 refrigerant. Any suggestions as to the cheapest way to convert to 134a or the other refrigerants on the market today?

Freeze 12 will drop in but its really a mix of R134 with other refrigerants to make it compatible with the R12 oil.

Does your system need work or is it just low on juice?

I tried changing over and killed my compressor. Finaly said heck with it and bought some r-12 off of ebay. It sells for about 15 bucks a can> Much easier and cheaper as long as you fix your leaks.

Short answer, the cheapest way is to restore your R12 system.

Isn't R12 colder anyway?

I would disagree with that, because theres always shortcuts you can take (freeze 12, R134 without changing everything, etc), but all things considered for things to work as designed, that is the case... For some having 45F air on a hot day in florida is better than having no air at all.

Ive had experience with this before, and with all that said, I would personally convert to R134a before I did anything else. Note that you have to entirely flush the system...

to buy R12 legally you have to have an EPA license, which consists of taking a quiz online for like $20.

If you dont ahve to take the system apart to replace something, buying a can of R12 and topping it off is the best way.
