Im changing my refridgent over to 134a. I vacuumed out all the old r12 and added 30 oz of 134a. The low side is reading around 20 lbs and the high side is around 220 lbs It should read between 35 (low) and 150 (high) any ideas?

Was the AC working prior to the work? Also, is it working at all now? To me it sounds like something is plugged.

Let me know.

No It wasnt working its been parked for 2 years. The ac will work if I force the compresser to run but the pressure gets to high on the high side. I think Ill replace the dryer and expansion valve any thing else you can think of?
