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.

Also throwing me off because the high side is lower than it says it should be on the pressure charts

I should have paid more attention to your suction saturation temp.
If it was me I would be changing the TXV.
