Regarding AC recharging.

[Skeith]

My AC on my 93 lumina is not up to par as it should be. Ive had the car for a year, and noticed last summer that the AC is not as cold as it should be.

Its not getting worse so I just figure it needs recharging.

However it uses the old R12 Refrigerant. (Unless it was converted to R134a but I don't recall seeing a sticker.)

My question is, the recharge kits they sell (R12a) supposed to be eco friendly replacement for R12 refrigerant. Can it be mixed with existing R12 or should I have it evacuated before recharging?

i've never heard of 12a, but it's container should state if it's compatible with R-12 or not.
