    This is not a DIY help site. Please read the rules. My advice is to call a technician to properly diagnose your equipment.

    I also deleted your second thread on the same subject in General Discussion, once again, please review the rules re' posting etc.

    If you are not DIY, what does "high side by compressor or evap coil is very hot" mean, exactly? What refrigerant is in this unit? The real question is 'why is there such a difference between high and low side pressures?' 300 and 60 are not r22 typical pressures for an 85 degree day and high space temperature. Seems like a restriction, and you should have seen this within the 20 or so years of a/c work. Good luck.
