likely restriction, or is this possible?
5 ton trane split system, condenser is on the roof. system cools a server room. at 55* ambient, i have ~100psig liquid pressure, close to zero subcooling, and amps in excess of RLA at the compressor.
Any ideas? i'm starting to think air in system.
p.s. 20* evaporator, with excessive superheat (TXV).
