Upon arrival the humidity was higher than set point for cool. The overcool function was disabled but fan would kick on to dehumidify but no compresser so fan only blowing wascausing humidity to rise. I explained to homeowner that system will cool 2 degrees below set point. I all went to condenser and the unit was very loud and vibrating. The blade looked as if it was out of balance. I ordered new blade and motor in case motor is damaged as well.
