What kind of pressure are you reading on both the high side and the low side?


Does the system blow cold?

Customer: replied 8 years ago.

no just able to check the low side. I can hear the compressor come off and on. Pressure is showing about 50 on the low side. The air cool at best


Expert:  Ron replied 8 years ago.
-Yes if it at 50PSI is running high, the freon is removed by evacuating the system with a recovery Machine, and the problem is there is no accurate way to know how much your taking out in less you take it all out. The proper amount is critical for the system to cool correctely. The best method is to have the system drained and evacuated and recharged.
