Tech before me added 3 lbs too much refrigerant before condemning the TXV and quoting the homeowner to replace the metering device and dryer.
I came out for a second opinion and found the issue in the first 5 minutes.
Homeowner said:
"You're the first person to look under there."
First thing to check with a frozen coil: airflow before charge.
Cleaned the coil, recovered the excess refrigerant — system running like new. ⚙️
