In the last 10 years we have bought three 18000 BTU LG window air conditioners. The first one lasted about four years and the pan and case rusted out. We replaced it what's the same model LG air conditioner and it lasted approximately three years and was damaged by Hurricane Matthew causing a mount to break and it ran for about a year very noisily. We then got the 18000 BTU dual inverter model because we figured it would last and run better than the last two unfortunately it only ran for one year and 10 months and then quit ( in the middle of the covid 19 pandemic if you buy the Dual inverter air conditioner make sure you get an extended warranty
