Emerson Quiet Kool SMART Portable Air Conditioner with Remote, Wi-Fi, and Voice Control for Rooms up to 300-Sq. Ft.

I read other reviews talking about how "noisy" this unit is, and I can tell you that's NOT the case for me. We've had 4 different units over the years prior to this one, and this is by far the most quiet! This unit is also the most powerful we've ever owned (14,000 btu's), and it's living up to the expectations! It keeps our entire main floor cool. Our house is about 3,300 sqaure feet, so the main floor is approximately 1,100 sq ft. That's MUCH MORE than the 550 sq ft It's rated for! It's currently 97 degrees outside, and it's a comfortable 71 in here! It's only been a few days so far, but we're more than pleased!

This is a great portable air conditioner! It cools down my 121sqft home office 7-10 degrees after running a while. It has great controls

I have misplaced my window kit and my hose. Where can I buy a replacement?

Exhaust tube is badly designed. It is difficult to connect to the unit and the part that is in the window

Meh. It cools about the same as the window unit that died. The air deflectors DO oscillate moving the hot layer of air from near the ceiling around, giving the sensation of it being cooler. The WiFi and connectivity to my Google Home rocks although the setup was a bit confusing as the included manual says one thing, the app says another and the QR sticker on the device links to a page that says something else yet again. The Google map link within the app does not function, but that is just for device location reference and does not affect geo-fencing (through 3rd party connectivity, the app itself is very spartan). Be aware that this unit is VERY HEAVY. Most consider me to be a pretty big guy and I had a little struggle. I recommend two average people.

item was missing parts looks used

I bought this to augment my central AC on hot days and as a backup if the central failed. What I didnt know is that it draws room air to exhaust for cooling the compressor, which means outside air must be drawn from other places, vents/doors/windows, bringing outside hot air in. Every time I turn it on while my central air is running my thermostat temp begins to rise about 2 degrees every hour, so its useless as an augment to my central air. Im very disappointed and I cant return it because to box was discarded. The description show mention this. Caveat Emptor

It's July in California so it's over 100 degrees today but this unit can't keep up if it gets over 90. (It's over 80 in here and it's set to be 71.) I have a room that is exactly 400 square feet with no dividers. I even insulated the exhaust properly. Plus it's not even quiet. I think it's the vents on top of the unit that vibrate but it makes it really loud you can even feel the noise.
