Ac was not operating upon arrival. After turning the system back on I found that the evaporator coil was starting to freeze over. I verified the airflow and duct pressure and found no concerns, I then started digging into the refrigerant. This is where I found my pressures to be off. I eventually found that the indoor metering device has failed and verified this with the manufacture. The office will be following up on a date that we can return to make these repairs.
