a/c problems

[mckrishes]

I double checked the readings. This time at 70 degrees fharenheit ambient temperature. I got low side readings of 25 and High side reading of about 250. According to the chart it should be around 35 for the low side and 160 for the high. I am not sure if this is significant for a leak, contamination or if I need to evacuate the system completely and recharge appropiately.
