Rattling Noise

The rattling sound is normal. Samsung air conditioners (in fact, most current air conditioners) have a pan on the bottom that catches the water that condenses on the cooling coils. Fan blades pick up the water and spray it as a fine mist onto the compressor, cooling the compressor. This process improves the cooling efficiency of the air conditioner and keeps its EER (Energy Efficient Ratings) at around 9.8. The rattling you hear is caused by the water hitting the fan.
