time when too much refrigerant Is also very good observation, you only need to turn on the air conditioner and turn off air conditioning,Observation of the refrigerant from the master to see the sight glass bubbles, if bubbles always see, pipe joints and no traces of oil, hand feeling significantly high and low side when the temperature difference felt, it indicates that the refrigerant Is too too much.
