Pros: Unit works well to cool down the air and the noise is tolerable.

Update I was impressed with customer service: minimal wait on the phone, courteous service and prompt replacement of the broken parts (read "Cons" below).

Cons: unit is made entirely of plastic so it breaks easily. To illustrate this point: while assembling, a plastic clip that holds the hoses to the window vent unit broke off. After 4 uses, my wife noticed that a clip that held one of the hoses to the unit itself had also broken off. Bottom line: it is flimsy.

A second drawback is that the window vent section does not adjust to the size of the window. (A piece that we thought would be used to adjust to window size is actually a piece used for a patio door.)

A third drawback is that the hoses and window vent section are rather unwieldy to handle. Frequently, while trying to place the vents on the window while coupled to the hoses, the hoses come off easily off the unit so it is difficult to adjust everything correctly. And yes, the hoses have to be coupled because it is seemingly impossible to try to put them on after placing the vent section on the window.

I rarely write extensive product reviews, but I made an exception because this product is in an area of my specialization.

Portable a/c in general

Do not buy a portable a/c unless you really need its roll about feature. You can purchase efficient (EER above 10), small and quiet window units at half the cost of portable units. That being said, you still might opt for a portable unit if you: do not want to leave a window unit installed permanently, do not want to lift a window a/c in and out of a window each season, do not have access to a large enough window for a window a/c, etc.

If you do decide to purchase a portable a/c, only purchase a two hose unit not a one hose. A one hose unit is almost a scam. It uses room air to cool the unit and then expels the air outside through the one hose. You have just paid to cool that room air, and the one hose unit is equivalent to placing a fan in the window blowing out. Hot outside air will be drawn into the room to replace the air being used to cool the unit. As a result, the unit will provide reduced cooling, and it will run inefficiently. A two hose unit, like this one, uses the second hose to draw in outside air to cool the unit instead of using room air. (This is exactly how window a/c's and central a/c's operate.) Consequently, the two hose unit can cool efficiently and at its full Btu/hr rating.

This particular portable a/c

This unit has the all-important two hoses. It is relatively efficient, not too noisy and will cool a nice size room (200 250 sq ft). For a portable a/c, this unit is as good a choice as I found available, but it has its problems. Here are some with which you must deal.

1. Portable is a relative term. This unit weighs ~ 80 lbs; it is only portable on one floor.

2. The unit is rather large and takes considerable room space. The front of the unit will be about two ft into the room which adds to the room space problem.

3. The hoses are large (5 in diameter) and, to my eye, rather unattractive.

4. The manufacturer recommends running the unit using only one hose at outside temperature above 95 F. So, if it gets rather warm outside, it will get warm inside too.

5. The worst feature of the unit is the poorly designed window installation kit. It does not expand to fit the window width. You will need a saw to make it fit, and then it will not fit another size window if you want to move it. The kit will usually need to be adapted further to fit a window. In my case, there is a window sill, and the kit is not high enough for it. I used some wood pieces, wood stain, my saw again, and weather stripping for the installation. In addition, the hose connectors to the unit did not fit. I used a sharp utility knife to increase the opening size of the connector tabs.

The bottom line: with all of its problems, if you need the feature of a portable a/c, this unit is as good as I found in this small size (9000 Btu/hr).

Honest reviews on Sunpentown WA-9040DE 9000 BTU Portable Air Conditioner with Dual

It is hard for me to decide whether to give this review one star or two. Since this is my second unit. I initially received the first one with a crack by the led display so I had to request a return from Amazon. Once I got the return processed, it took over 2 weeks to get a replacement. Once I got the unit, I took it out of the box and did not like what I see. The unit looks old right out of the box. I can clearly see wear and tear by observing the the dust and cowebs on the inside of the window hoses.The unit works but it does not behave like one that I bought new from Amazon. I noticed it is moderately louder and occasionally makes buzzing sound when it is set to 73 degrees. I am not sure if the shipping department sent out the wrong order or thinks that I don't mind a refurbished or returned unit. As I remembered, I paid for a new one and not someone else return. When I first received this, I was thinking about returning the replacement unit but the heat in the house took anyway any motivation to do so. One advice I can give is...if you received a broken unit, I would not advise requesting for a replacement unit. I would request for a refund and reorder again. Learn from my mistake!I would never request for a replacement unit again from Amazon.

Pros:

Worked out of the box

Very quiet

Inexpensive

Outside air intake (sort of)

Broken window adapter replaced under warranty at no cost and little effort

Cons: This item is poorly designed. The manual states that the outside air intake must be detached when the outside temperature exceeds 95 degrees F. to prevent the compressor from overheating (this isn't easily done). Also, the unit mixes room air with the air sucked in from outside. Naturally, this largely defeats the advantage of a dual hose system. Also, the hoses are mounted right behind the cooling coils, which probably disrupts air flow through them. Finally, the parts themselves seem sort of flimsy (particularly the tabs that lock the air hoses to AC).

Other Thoughts: I'm a little disappointed that the thermostat only goes down to 64 degrees. It's worth being aware that the fan seems to run constantly even when the compressor isn't on, and there seems to be a noticeably loud water pump (a guess) that frequently cycles on and off when the humidity is high. Also, this unit comes with casters. You could unscrew them, but there are bolts sticking out past the bottom of the unit.

For the price, I'm satisfied with the air conditioner, but you can probably find better at a higher price point.
