Apparently, I'm now a "crew"
OK friend call tonight say his Girl friend's AC " been having trouble" so he call a large national company.
here's the techs what the Trip sheet say's
unit 9 year old split
OA dry 93 OA wet 82
Suction 53 Head 220
SH 40 SC 10
Fan 4.1 Comp 16.2
Unit low on charge coil has leak Unit needs replaced
OK not much know about unit but with age I'm guessing its R22 based on age.
I told My buddy "OK I'm very rusty but I think he full of BS"
Comments PLEASE I'm that rust
Head 220 suction 53 SH 40 SC 10 and he say LOW ON CHAGE
Head looks about normal for that kind of ambient.
A piston MD might run a higher SC than a TEV unit.
Given that and ASSUMING that the airflow was correct, I'd shoot a bit of gas in it and see what happened.
Low airflow would tend to give you a lower Superheat.Quote:
