A chemical or plastic smell from a newly installed LG ceiling-mounted air conditioner is normal for a new product. It is similar to the smell of a new car or new furniture. This is temporary and does not indicate a defect. Open the windows and run the air conditioner in [Fan Mode] to help clear the smell. The smell will naturally fade within 1–2 weeks.
Please note
- On a clear day, open the windows and run the air conditioner in [Fan Mode]. Avoid doing this on dusty or humid days, as dust or moisture may enter the room and the unit.

When you first turn on a new air conditioner, the internal parts may give off a slight smell. This is normal and comes from the manufacturing process. It will gradually fade with use.
