Hi to all I've got me a problem here where the suction pressure on this Carrier A/C 30 ton system reads 50 PSIG. Three compressors have been replaced already. The evaporator coil has been cleaned. Any suggestions ?

That high side psi is kinda high for a 50 psi suction pressure. What was the original problems that cause the first compressor to be changed, and is this a roof top unit?

if this a 30 ton ac instead of 2.5 ton 30'000 btu ac i think i would look at the txv at the evaporator coil this sounds like it is not opening correctly make sure its sensing bulb has not come loose from the suction line please let us know what you are cooling with 30 tons of ac

A model # and serial # would help.

You most likely has a restriction on the orifice, it is located between the header and the distributor.
