That changed when i started to use that kit. I guess faulty temp readings is the reason so many argue they get subcooled liquid at the condenser outlet in units with receiver. When you have a receiver with 50cm pibe between it and the condenser outlet, it is absolutely 100% impossible to have any measurable degree of subcooling if the receiver isnt full of liquid and you dont have uncondensables in the system.
