Cleaned both condensers coils First floor system. Standard AC Split system. Checked all electrical. measured pressures for R22 at 50/121psi with 3 degree sub cooling with outside temperature at 56 degrees.. Measured temperature drop at 23 degrees. Cleaned evaporator coil and condensate line. Changed 20x25x1 filter. Performed efficiency test utilizing MeasureQuick. System received an C+ grade but mainly for age not cooling ability. System maybe slightly low on phased out R22 refrigerant but is running as it should.
