Haier ESA405P Energy Star Window Air Conditioner, 5100 BTU

I have a 10 x 10 room and this thing is a powerhouse. The noise is easy to get used to and is as loud as any standing fan. Cools the whole room in about 15 minutes and keeps it at temp. I took apart the box it came in and jammed the styrofoam into the window sill gap and then taped the side window covers it comes with over top and it surprsingly insulated the sides. Being in college I didn't care how it looked. I run it at night and as long as you set it to "stay cool" it won't cut off randomly, but if you leave it on the starting setting it will try to keep turning off to save energy so just set that straight and you're good.

Works well and as intended cools my small room down

Air conditioner is working great keeping a small 2nd level bedroom cool and comfortable. Chose it for its energy star rating and was pleased with the small effect it had on our electric bill.

Do not buy this. Sure, it cools a room okay, but it that's your bedroom, you have no chance of getting any sleep anyway. This thing makes a God-awrful racket... not just a little noise, but a racket. It sounds like an old diesel engine. By far the loudest AC unit I've ever owned. Wish I hadn't bought it.

Not happy at all. Fan on low is too much, this I can take care of. What I can not work around because it is designed tomdo this is when you turn it back on after you turn it off the settings reset to mode and temperature "they" selected.So for instance if I use the fan, turn it off, turn it back on energy efficiency 72degrees comes on. Ok its a pain but to boot, you really can't see where you are at with regard to mode, from across the room. Now you have to got there, which negates why I got one with a remote.Agree with others, not for a bedroom, fan is loud.

It's ok...does a good job, not a great job of cooling down the Master Bedroom. 12x12 shouldn't take too long to cool down, but it took a good hour to bring the temperature of the room from 82 to 75 and then another hour to bring it down to 70.I don't recommend buying this one for larger rooms or to cool down an entire apartment. Won't work.If you want the bedroom cool enough before bed you'll need to start it 1-2 hours before you go to sleep. The timer is a great function and having the remote control is also nice.Definitely not the best AC unit I have purchased but it also is not the worst unit.

Perfect for bedroom sized room. Easy to install and remote is helpful for lazy days! Highly recommend this AC!

Love!! Easy installation, love the temperature control element and it cools our bedroom faster than our central AC.
