High head pressure has me worried!
Changed evap coil on 30 year old 5 ton commercial split yesterday. Temperatures were extreme here in St. Louis to say the least, but 375# head pressure has me worried. Any feed back would be appreciated, all data listed below.
Indoor entering drybulb: 95.5 deg
Indoor entering wetbulb: 80.4 deg
outside ambient: 110 deg
Low side pressure: 80#
High side pressure: 375#
Suction line temp: 84.2 deg
Condenser leaving temp: 142.7
Cond delta T : 32.7 deg
Charged to target superheat of 34deg ( 84-50). Could the high head be due to extreme conditions or could there be something else?
Call for Heat means get more firewood
