Okay, I posted this on Instagram and one comment was in the realm of, if you don't know this is a plugged TXV you should change companies. Huh? There is only one way to know, first ensure the air flow is right, make sure blower isn't in reverse, no dirty filters evap coil. Check across the filter drier, more than a 2⁰F difference, it must be replaced. Then check SH/SC. This will tell you everything. High SH and high SC is considered a liquid line restriction, if it's not the drier, it's the metering device in most scenarios. High SH and low SC is most likely low charge. Let's not guess!
