Re: More a/c questions



If your low side pressure is that high you probably have air in the
system. You have to pull a HARD vacuum for an extended period of time
to evaporate (boil) all the moisture out and get out all of the air.
Recover the R-12, leak-test again, and a good idea would be to replace
the "O" ring at the "loose" fitting. It would also be good "insurance"
to replace the dryer, orifice tube, and refrigerent oil. Just getting
the system to blow cold is not what you really want. If the system is
contaminated then in the not too distant future you will have even
bigger problems like internal corrosion which will eat the system from
the inside out and kill the compressor and all the aluminum. All of
the small orifices will plug up. You will wind up replacing the coils,
lines, compressor, and valves.
