upon my arrival to del valle, tx., I found that the indoor ac system was extremely dirty and the system appeared to be over charged because it has a high head pressure and subcooling. I increased the airflow to get a little more airflow across the coil. I recommend a pull and clean on the system and while we do that we recover the refrigerant in the system and weight it back in. The client can’t do the repair right now but will call us if he has more issues.
