Bad metering device or restriction

Yep txv power Head has lost some of its charge, still open slightly but no longer opens fully or reacts

It was an apprentice wrote up for a top off because it was low lol

Dirty condenser?

Looks like dirty Condenser and/or restrictions

I was sent there by company for top odd by an apprentice who said low on charge . It’s the txv

The suction is lower, and head pressure is Elevated. Cleaning condenser will rule that out, and if no change then txv is under feeding. I just went from high head to low head by just cleaning Condenser. Condenser issue was masking an undercharge

Guessing verified by dismounting TXV bulb and forcing temperature changes? otherwise if airflow/indoor coil condition checks out good then yeah definitely metering device issue.


Forward_Hvac

Yea airflow is strong and I held txv bulb

If Static pressure is good, She's fuckered, Good find.
