After enduring five hot summers in my new place, I finally decided to get a portable room air conditioner to help beat the heat.

After a little bit of searching, I settled upon this Sharp unit. I liked its clean styling and the easy installation diagrams it featured on the outside of the box. The $50 instant rebate offered at the time also helped -- a lot.

The unit comes with various panels to aid in the outside venting installation. The 5" diameter flexible hose seemed kind of g-normous coming out of the box. But its semi-rigid construction has a built in screw-like segmentation - which makes it easy to hand twist the hose into the a) the unit itself and b) into the window adapter - no tools required. How cool is that?

It took me about 20 minutes to install the window adapter and frame into my outside window (with just a bit of drilling and screwing).

But when I turned the unit on - I couldn't believe 1) how quiet the unit was and 2) how really cold the air was coming out of it. Halleluiah!

My two cats watched curiously as I set the unit up. But they both managed to find favorite spots - downwind - which have now become their preferred nesting places during the day. Who says cats are dumb?

The a/c vents on the front seemed small at first. But they open automatically (to help keep the unit clean) - and their limited size - actually helps to increase the speed of the air flow for greater projection.

I've closed the doors to all of my other rooms - to confine the cool air to the kitchen/dining room and living room. I have no idea how close this area comes to the suggested 400 square foot maximum. My place has built-in air-conditioning, but I'm really looking forward to seeing if I can do without it for the entire summer.

After living with a myriad of room fans - and even an indoor dehumidifier (which was a lot louder and vented its own heat out of the back) - I can already tell this is shaping up to be the most comfortable summer I've yet to experience.

The Sharp portable a/c comes with a hand remote - which is used to control the settings. There is only a power switch and some indicator lights on the unit itself. I use the automatic control - to set a desired temperature - and the unit does the rest. Also, when the programmed temperature is reached - the unit goes to a reduced output mode - with a bit of cool air still coming out. Nice.

But even when the unit is running - it is still a lot quieter than my numerous tower fans and my old room dehumidifier. It's also much, much quieter than my dishwasher. And almost as quiet as my refrigerator when it's going.

I also went outside to see how much air flow was coming out - and it was surprisingly quite a lot. And the exhaust temperature was fairly warm - which indicated to me how much of a heat transfer was actually taking place. Nice.

Since I use my dining table as my desk - when I work at home - having the Sharp portable a/c just yards away makes me as cool as I've always wanted to be - year `round.

Will my overall energy bill go down by having this new Sharp portable a/c unit? I can't see why not - since I'm not cooling my entire place. However, only time will tell.

For now - I couldn't be happier - or more comfortable. I think it's shaping up - to be a really cool summer. If you can afford the up-front cost - it's worth it. Please, don't miss out.

Have you ever purchased something that turned out to be even better than you expected? Of course. Well that's the feeling I have with this quiet and powerful little dynamo. First, rather than repeat the exceptional lead review by Aaryanna, one which echoes my sentiments to a tee, I will add to her exposition by explaining the title of my review. PlasmaClusters! Who knew? Aaryanna had so much to say about the A/C's features she was too tired to talk about the ions. All I wanted was a sturdy and reliable portable A/C for my bedroom. I live in the San Fernando Valley of So. California and right about June 20th to July 1st when the temperature hits 95F for the first time, the daytime temps will seldom dip below 88 again until about, um I don't know, Labor Day. Night temps will mostly stay above 80F and can average 85F for a week at a time. I have a one bedroom apartment with the unit's own built-in wall air-conditioner in the living room only. Last year on the hottest nights I'd set up a three fan series starting at the air-conditioner with a second fan midway to my back bedroom and the final fan around the small corner leading into the bedroom itself. As you might imagine, this jury-rigged little setup was not only inefficient, but required me to run the wall A/C at full blast all night to get even four or five degrees of relief. Not cheap! You can imagine from Aaryanna's review, this A/C marvel is just what the doctor ordered. Now I wonder what took me so long.

What I didn't expect was the patented Sharp Ion Generator. What kind of of little doodad could this be? Fries with that double cheeseburger sir? Just Google Plasmaclusters, wow! This is no gimmick, hence the patent! There are pretty expensive Sharp Ion Generator units sold all over the world that do only one thing and very well at that. They scrub your air of harmful microbes, dirt, and pesky viruses in a patented way that has little to do with all of the other ideas you may have had about ion air cleaning machines. Are you ready for this? There is a "REFRESHER" function which when activated will cleanse the odors of any garments you choose to place in front of the unit, including simply placing the unit in front of your closet and de-odorizing your entire wardrobe. I won't bore you with particulars, that's what Google is for. Check it out.

So, I've got a great air conditioner, a great dehumidifier, a great room air venter, and a first class sleep mode no louder than a good frig. But who knew it was going to be one of the healthiest things I've ever had? I would have paid the same money for the A/C qualities alone. It's as if they threw in the Ion Generator out of their concern for my health! Who knew???

******UPDATE 05/05/2013******

I was pretty happy with the price and how effective it is at cooling the room, but the rattling was really getting to me. This was a refurb for 250.00, so I expected that it may not be perfect. So I took the housing apart to find out why is was soooo noisy. Dismantling was actually very easy. After removing the 2 screws at the bottom front, the front cover slides up and I was able to get to most of the problem area's. All it needed was some new foam buffers where the plastics were touching (very cheap fix).

That probably should have happened at the factory when it was refurbed. For that they loose 1 star.

Still, it is a pretty great unit. I hope I don't need to contact customer support. That looked like it was going to be a pain (automated voice system), I gave up...

Original post:
I live northern New Mexico. Summers get into the high 90's for a couple months, it gets to 100 or just above for a few day per year. Our house was built in the late 50's. The AC unit is for the master BR, an old enclosure of a 2 car garage, with old metal casement roll out windows from the 60's.

As far as installation, it might have been easy if I had modern sliding windows, but I don't. The only part of the included window adapters (which seem pretty well made) that I could use, was the vent port. I opted to remove 1 pane of glass (from a six pane window) to fit a piece of plexi glass with a hole cut for the vent port. It worked perfectly. I have the AC unit right under it, with the hose going straight up to it.

There is a good bit of heat generated that goes through the vent hose to the outside which heats the vent hose up considerably. When sitting close to it, you can feel the hose cancelling out some of the coolers effectiveness. I bought a 6 foot duct sleeve at the home depot for around $6.00 to insulate the hose and that made all the difference (it simply slips over the vent hose like a sleeve, duh. Then some tape or zips to hold it). I can't feel any heat from the hose now (Sharp should probably include that with the cooler).

The cooler does definitely cool the room down with NO trouble. The biggest issue that I have with it is that the plastic housing around the unit can rattles A LOT if it is not positioned just so... I have to mess with it for a bit to get it to stop chattering. I now have it propped up in the back with a 1 in piece of wood to keep it quiet. Other than that it works really well.

I wouldn't really consider it portable. It's just a good alternative to construction to add ducting...

I would recommend this AC unit, but I would not pay $500.00. I paid 250.00 for a referb.

Pros:
1. The unit showed up in two days!
2. Easy installation.
3. Cools effectively.

Cons:
1. I live in California and the weather has been quite warm. The unit's water tank fills up in 2-3 hours which automatically turns air conditioner off. To further compound my challenges with the unit, the only means to drain the water tank is wheel the entire unit outside. This is not an easy task due to the size of the unit. I would have expected a removable water tank at a minimum. Even better, would be a drain hose or other means to remove the water from the unit allowing it to run for longer periods of time required to allow this unit to cool the room. All in all, unless I am open to wheeling the unit outside several times a night to drain the water tank, this unit is ineffective for my requirements. The support line, although I received conflicting responses, indicated I can attach a hose to the water tank drain allowing me to drain the water tank either outside or to an indoor drain.

I used the 2 reviews that were already here to help me buy this product. I was not disappointed. The Midwest is in the middle of a heat wave. I installed this unit around 6 PM and our berdroom cooled down enough to sleep well that night. The next night was even better, as we leave the unit on. We have a second floor bedroom that is above our garage, so there is heat coming from everywhere. We were freezing out the rest of the house using the central A/C, but now have turned that up to 80 degrees, and use this unit in the bedroom.

The unit is very quiet at night. We put the fan on low. It provides a very nice "white noise" which covers up the traffic noise very nicely. The unit works so well, we have to burrow into the covers. Plus the ion generator leaves the room smelling fresh and clean.

Unit is very heavy, so you need to be careful when you get the package. But once it's out of the box, it does have wheels so it does move around easily.

My only complanit is the part that attaches in the window. I had to trim some off the flange, as my window was narrower than the flange, so that weakened it a little. I'm going to build my own and attach the exhaust hose to that as soon as the heat wave is over.

All in all, I highly recomend this unit. We're sleeping better than ever.

People seem to be complaining about the unit not being Strong or Cold enough, but to be honest, I like that its not Ice Cold.
Really cold Air Conditioners tend to dry out my throat and can actually make you sick if you are constantly near the AC.
This one is just the right temp and also you have to realize that for the "very quiet operation" you have to sacrifice some "heavy power".

Pros:
Quiet (Even less than some window units)
Very Solid
Cool modern look
Easy to setup
No more draining, especially for dry western states.

Cons:
Maybe too large for some people & Quite heavy
When the fan is on low I can hear a buzzing sounds that seems to go away after a few mintues.
This is the ION generator which automatically turns on when in fan mode and wish there was an OFF for the ION deal.

Overall great AC unit that should last a very long time.
Enjoy! (and newegg sells it for $399 + free shipping)

Hostages. Deathrow inmates. Mothers-in-law.
These are the types of people that deserve the kind of relief this unit provides on a sweltering day. With temps hovering between 90-95F, you don't exactly have alot of patience for sub-quality.

I dont mind the noise. I could tolerate the weight. I could deal with the laborious draining requirements. What I cannot tolerate, is semi-cool air coming out of $400+ machine turned up to the Max in a 3rd floor apartment.

One Star = the remote works

..and to the people at Sharp,
I'll tell you what my mom told me when she met my first girlfriend..."you can do better!"

Don't buy this thing, ok?

We're on our 4th year of running this and have learned (the hard way) that the level of the floor it sits impacts the way it functions. Our house is old and the floor at the wall is higher than it is 6 inches into the room, and this is enough.
1)when we just sit the machine on this downward-sloping floor, it will flood (and keep operating)
2) being extra careful this year setting it up, used a level for the first time, and the machine filled with water and then stopped.
3) adjust the leveling a bit, to tilt the front down just a bit, it worked fine, and we've been using it for a month with no flooding and emptying.

Hope this helps some of you who already own one. The noise doesn't bother me, and it cools OK.

Seems great until the unit shuts down after 2 hours or less of operation - and this is only end of May! The tank fills up, and the entire bulky unit must be disconnected from the wall plug AND the exhaust hose, wheeled outside (over the front door rail) and emptied. Stupid design. While a removable bucket would be an improvement, emptying the bucket or moving the unit every 2 hours is a waste of money and time. A unit of this cost should self-evaporate through the exhaust pipe or include a pump and hose that exit thru the plastic window fitting. Most of us could live with a clear plastic hose running off to our planters or garden. Why didn't the mfgr think of what people would have to DO to use this?

I got this at costco last august and havd used all options, modes etc. Dehumidify is fantastic but it does a REALLY good job and will indeed fill the water up fast with 1-2 hrs of use a night. If i use a/c instead it lasts much longer! We wheel to the stairs and empty into a small pail by the way but are going to build a platform and put a tub underneath. I stored it over winter anx busted it out midmay and am in love with it all over again. No complaints!!
