I'm not one hundred percent on what subcooling should be. I forgot the tp chart.
From the info you've given you're running a 10 degree subcooling. That's about normal.
However, as prodiyer said, check and charge a piston (bullet) metering system with superheat. Difference between saturated vapor temperature in evap and temperature of suction line outside condenser is called "compressor superheat". It lets you know how well the compressor is being cooled and if your evap is running flooded, proper, or starved.
Piston metered systems are critical charge. If you don't nail it, the system will suffer performance loss.
Electricity makes refrigeration happen.
Refrigeration makes the HVAC psychrometric process happen.
HVAC pyschrometrics is what makes indoor human comfort happen...IF the ducts AND the building envelope cooperate.
A building is NOT beautiful unless it is also comfortable.

If people want correct answers... we need information to do so!
If, you are not willing to get/or ask what some of the info needed is... why should we spend our time trying to help?
