What would cause high pressure on the low side? This is after evaporator, compressor, expansion valve, accumulator, and condenser replacement, basically everything. Air is cool, but not cold, and won't keep you from sweating in this 90+ degree weather. I replaced everything, and then had the shop evacuate the system, recharge, add oil to compressor and perform leak test. I know a bad compressor could cause this, but is brand new. I replaced everything, so there should be no blockage anywhere, either. Thanks!
