410a unit in cool mold pressures 148 Low 275 high with 80 something supply temp inside
That is a high suction pressure should be running about 46 psig and head pressure should be amibent temp or outside temp and add 25 to it. that will give you approximate head temp. sounds like you have a dirty condenser I would clean it. Check your amp draw on your compressor if its high then I would check for dirty condenser. You can clean it with a stiff hair brush go up and down do not go sideways because you can damage your fins on the coil. Then take a water hose and wash it out. turn off the power to the unit before cleaning do not clean with compressor running. turn off the breaker box. I hope this helps.
