Commerical system has extreme high suction, and low head. Twinned evap coils, single condenser, with 2 compressors. No funky noises. 120 psi on head, 1 degrees subcool, about 95-100 on suction, 66 degrees suction line temp. Indoor delta T is about 4 degrees. Each evaporator coil has it's own TXV, didn't notice external equalizer. Doesn't make any sense, both TXV's cant be both stuck open?, and or both compressor's can't both be bad? Possibly condenser running backwards from reversed phase? Please need help/adice!!! Thanks

It sounds like one of your compressors has a broken discharge valve.
