Was charging a system early in the morning today (fixed bore) and had a return air wet bulb of 65 f and outdoor air temp 70 f. That gave me a target SH of 22 f. That seemed really high to me. Could someone explain this? I left the system with about a 16 SH. The suction pressure (R22) was 65 and highside was about 200. I know thats low but it was the best I could get without decreasing the SH even more. I am new to the field and would appreciate any input. Also should I be expecting a callback on this one. Thanks in advance
