    Low charge = low pressures both sides typically, again I say typically there are always exceptions.
    High head =
    dirty condenser
    overcharge
    fan problem
    re circulation
    high load
    and other factors like your bent fins, comb them out and see where it runs.

    Welcome to the trade, keep practicing we all are, and when you post a question you are our eyes and ears at your site give us all the info and we will help. Always need pressures, temps, subcooling and superheat posted to give good answers Good luck
