I'm sorry to hear about your issues with your mini split. It sounds like it has lost charge and this most likely happened as a result of the move. The dripping water can be caused by the coil icing up and melting on the off cycle.
Sorry, was out doing service calls all day. On these mini split systems, most of them have what's called a "critical charge". That is, you weigh in an exact amount of refrigerant. This must be done by removing what's in there, and then using a refrigerant scale, an exact charge weighed in according to the manufacturers specs. The reason both lines are cold is because the system is not doing what it's supposed to be doing due to low charge issues.
OK, thanks for the update.
Did you have additional questions on this? Otherwise, good luck! Thank you for using Just Answer and please don't forget to rate my service as that's how experts get paid (Thanks in advance for any bonus left). Otherwise experts work at their own time and expense. Feel free to post back with any additional questions.
Have you zeroed out your gauges before checking?? Sure they are accurate?
If there was a restiction, it may have broken loose. 150 PSI is about a 53 degree coil, about right for an average day. Which is why I asked about guages. However, if it is freezing up, then that indicates a problem.
Probably will need to evacuate system and purge with nitrogen, then vacuum and recharge. I would also pressure the system with nitrogen when the charge is out and see if it holds pressure to make sure you have no leaks. It doesn't make sense that the pressure was low one day and (almost) back to normal the next unless there is a restriction in the system. Also, make sure it is not an intermittent blower issue because loss of evap blower would cause low side pressure to go way down and coil to freeze.
I still think you need to do the evacuation and purge as mentioned previously, then weigh in an exact charge.
