Q: R12 looks cloudy

asked by on

The R12 looks a little cloudy, and it takes a while longer to cool off.

When you say that the R12 is cloudy, I assume that you are looking at the sight class on the receiver drier. When oil is going through the drier, it may look like a cloudy liquid. If you cannot see through the sight glass, then you may have a leak in your system, or the system is overloaded with oil. I recommend that you have a mechanic, such as one from YourMechanic, come by and inspect your AC system.
