Honeywell - 450 Sq. Ft. Portable Air Conditioner - Blue/White

This AC has a slightly louder fan/rattle noise than my previous Denali portable. It functions nearly the same as every one I've owned before - which is to say not as powerful as a window unit, but capable of cooling a single room. I have a work room that gets hotter than the rest of the house and this shaves a few degrees off the temp. I can typically get this room to be 76-79 with central air, then this unit will take it down to 71 from there. If you rely on the portable alone you would not be able to shut it off for any time period if it was over 80 outside, and you will have only a small room to feel comfortable in. If you don't mind the effort/installation/permanent nature of a window unit, you will find those perform better. However, this allowed me to be able to open my window and use a fan instead on nights that were cool outside. As with all portables, the hose and window bracket fit loosely together and I used packaging tape to secure the hose to the unit and bracket. I had to do this with everyone one I've ever owned, so it's not limited to this model.

I purchased this AC for our third bedroom upstairs which is generally warmer than the main level. I bought this model knowing that the BTU of this unit more than covered the size of the room. This is a decent AC and worked really well at night when the temps were in the 70s. But it could not get the room to less than 80 degrees during the day when the outside temps were in the 90s. It probably would have worked better in one of the main level rooms when it doesn't get as hot. Also, be warned that if you are installing the exhaust into a narrow window you will have to do some cutting of the window guard. It's too short to cover the entire window but with the extension it partially covered the hole for the exhaust connection.

This AC isn't quite as powerful as my previous unit but it's much quieter. The auto-evap system appears to work very well. Every time I check the drain ports on the back it appears to be empty. I use this in the bedroom to keep it cool at night. It takes awhile to cool the room so I usually turn it on a half hour before I turn in. I wish you could direct the fan blades. I use a box fan to help circulate the cool air where I want it. Works very well in my case but I wouldn't recommend it for a large room. Installation was mostly easy but I had to carve through one of the window kit sections in order to make it fit.

I live in north central Texas and it gets hot!! My bedroom is a garage conversion and although there is insulation in winter the room is significantly cold and in the summer it gets really warm. I went 4 summers suffering in this hot bedroom trying to make it with a ceiling fan and I never even thought about buying a portable a/c. Thank god i came across the idea of buying one because it is a life saver! My room is pretty big and cools quickly! The size of the a/c is a bit larger than I thought but it doesn't matter because I can stay cool now. I personally don't think the sound is too loud, it's comparable to an air purifier in loudness. Buy this if you are done being hot!

Our A/C broke at our house - we live in Houston,TX so you can imagine how hot and humid it was. The self evaporating system worked flawlessly. During the heat of the day it kept our bedroom at 72 degrees and at night as low as 67 degrees. The noise also isn't as bad as some of the other reviewers complained about. But we are used to having a fan on because even with our ac working it gets hot. So its about as loud as having a small tower fan blowing. Worth every penny. We are extremely satisfied with this product.

I bought this AC just because it said it has a auto evaporation system but it doesn't. i called Bet Buy to return and they said they will not take it back and said to call the company. i just got fed with all the non sense and started to put a bucket under the AC now which looks so odd in my bed room. Best Buy should stop false advertising else they will end up in consumer court one day. Not happy with this purchase at all. Now i am forced to use this stupid product with a bucket underneath. I cant even drain the water out with the hose as there is no opening to my window.

I live in an apartment building that decides when they will switch on the a/c and with weather constantly changing from March - May, I needed something that would keep my home cool and comfortable until they switch over. I have a 960 sq. ft. home and it had kept it comfortably cool on the very warm days. It is not as loud as some of the reviews had mentioned. It is a bit bulky (especially the exhaust hose), but being cool and comfortable is well worth it.

This 10,000btu devise is big and bulky--but that's to be expected for any portable AC and not a reason to deduct stars. The issue was that it won't cool a room about half the size of the square footage in the specs below 74 degrees while it's still hot outside. And I live by the beach where the high regularly only gets to 85. I can't imagine how this would do in a region that reaches triple digits with high humidity. Plan to try the 14,000 btu version to compare.
