Is it normal to see water dripping from the back of my LG LWG07-Series air conditioner?
Yes, water dripping from the back of the unit is normal, especially in high humidity or rainy conditions. Water is collected in the base pan and overflows out the back of the unit. A whistling sound may also accompany this, as moisture is collected by the condenser to help improve cooling efficiency. (Page 20)
