There may be a difference in how each gas effects different seals & gaskets, so they probably should be changed to compatible items. But the cost may not be worth changing until there is a problem if any, then get a recon done.
On a vehicle or house system, pump out the Freon r12 into a gas bottle (well vacuum the bottle 1st really to suck it in).
Then pump in R134a (well vacuum the aircon system & then it sucks in the R134a).
Or - just ask a Refridgeration maintenance guy to filler-up & check for leaks.
Would have been built for R12, can be converted to R134a.
It came with R12. Due to the high cost of R12, I suggest you convert it to R134a.
R134a Freon is an oxymoron, Freon is R12 but the answer is yes, a subtle 'sweetish' odor
R134a
OEM refrigerant which came installed in 1993 was Freon R12. I suggest you convert it to R134a if it has not already been converted. R12 is far to expensive.
It is still possible to aquire R12 Freon, but the cost is excessive. My advice is to convert the system to R134a.

Unless it has been converted over to R134 it came with R12. I suggest you convert it to R134a. R12 is very expensive.
It was built with r12. It can be retrofitted to R134a.It was built with r12. It can be retrofitted to R134a.
No, uses R134a.
Most systems can be retrofitted to R134a
None, the refrigerant is R134a not Freon which is R12.
