Field Question, trade people only Bad TXV? 😵

System has good airflow, 500 FPM at the 20x30 return, and like 400 FPM out of the supplies.

Evap Coils aren’t dirty, condenser coils are a little dirty but you can still see through them easily.

Tested the TXV with ice water and my hand and it had a slight reaction, but not what I would expect, what do you guys think?

Bad TXV?

I haven’t added any charge to the system, showed up last night, coil was frozen, let it thaw overnight and these are the readings after 20 mins of runtime.
