    I had a 15000 btu lg that got damaged and quite working bought this 18000 and it doesn’t cool as quick as the 15000 did I’m very disappointed. Our house is only 850 square feet and I thought getting a bigger unit would cool faster but it doesn’t. It’s nice that it’s quiet compared to the other one but that’s it. It was bent up on the inside by the coils but the housing was not bent so had to be bent at the factory not during shipping. After running all afternoon it mad it to 79 degrees in the house when it was 101 outside and now it is 77 in the house and it’s 74 outside. Our 15000 kept it 72 in the entire house I should have just bought the same one again.

    Trouble out of the box

    Once you get this AC working it works well and quietly. Out of the box tho, you had better be crafty. Spent 2 hours setting it up, then turned it on the first time and the fan sounded like something was caught in it. Very slow, and sounded like the actual fan was broken. I called Geek Squad, who were no help aside from "We can have someone pick it up. Someone will call you in 10 business days" So, I popped it out of the case to take a look. It turns out that the O ring that holds the fan to the spindle was never installed properly. The fan literally fell off inside the machine. After messing with it for an hour, I got it to work properly.

    I would purchase again. For a wall unit, it is smooth sounding and not too loud.

    I've only had this baby a month, but, so far, I am extremely happy with it. It cools quickly and efficiently, and hums quietly along while doing so. It also looks unobtrusively good. Highly recommended!

    Good so far but I haven't had it that long so only time will tell. Keeps my living room and dinning room nice and cool. Its also pretty quiet which is a plus. Haven't tried the smart app yet, I just use the remote. I like when it tells me when the filter needs cleaning. It also has an energy saving function. 5 out of 5 so far. Hope it lasts me a while.
