Great AC. I got this to replace my 14 year old ac that was extremely heavy but still worked. I got tired of dragging it up and down three floors at the beginning and end of ac season here in the northeast. I measured the room and got the correct btu. Easy to install and easy to use functions. Strong fan speed and cools room quickly. I love all the automatic electronic features it has. The only thing that is annoying is when on auto eco mode it constantly turns on and off during the night which disturbs my sleep. So I turn those features off. That’s the reason for 4 star rating instead of 5 star. Noise level same as all the new AC’s today which could be a little quieter but it does put me to sleep.
