[LG Air Conditioner Sound] Outdoor unit generates louder noises

When the indoor temperature is high, the inverter type air conditioner operates the compressor at higher speed, thus quickly cooling the indoor environment with strong coldness, but the high pitch noises will be louder. When the indoor temperature is adequate, the compressor runs slowly to maintain the temperature with low coldness and thus the noises will be less loud and power saving effects will be improved.

※ While cooling operation takes place, the noises from the outdoor unit become loud and quiet repeatedly, and this is normal, so rest assured when you use it.
