It may be that it's just a defective unit, however when I contacted Amazon.ca to exchange it, I discovered that with this unit, even though UPS was able to ship it to my door, Amazon.ca told me that I had to return it by bringing it to a local post office. Considering the size of the box and a shipping weight of 96 pounds, I may have to find someone with a van or truck to help me get it to the post office. Because of this, I wasn't willing to risk getting another one, just in case the tone is common with this make/model.
It's too bad, because in all other respects, this unit could have worked for us. The compressor is much quieter than another brand we have. The fan also blew the air more upwards than forward, so there was less of a cold draft across our bed. The white noise of a fan and the compressor going on and off is easy enough to get used to. But the constant tone is reminiscent of the off-air tone of a TV station. I couldn't sleep through that either.

Since I have sliding windows, I really couldn't use a window air conditioner. There are casement air conditioners sized to fit sliding windows, but the selection isn't as good. I wasn't really considering a portable air conditioner because I only knew about single hose units and there were too many drawbacks.
The idea of a single vent portable air conditioner is pretty attractive until you consider the thermodynamics of it: all of the heat producing parts are in your house -- which means that you have to cool them too. And even though the gets vented to the outside, that air has to come from somewhere... like that precious cool air that you just made. And all that air being blown out the window has to be replaced, which means hot air is being sucked into your cool room under the doors and through various air leaks. In short, while you're trying to cool the room you're fighting against the heat from the compressor, the cold air you're throwing away, and the hot air that's being sucked in. A single hose air conditioner is the worst way to cool a room short of leaving your refrigerator door open.
*** That's why you *want* a dual hose air conditioner. It solves two of the three big limitations of single hose portable air conditioners: it uses outside air for the condenser (hot side) core airflow, so it doesn't waste your just cooled air, and it isn't replacing that cooled air with hot air. The hot side stays hot and the cool side stays cool. Sure that pesky compressor is still getting hot, but the only way you're going to solve that is to buy a window air conditioner.
So, needless to say I'm quite happy with my purchase. It gives me 1/3 of the cooling of a whole house AC, for less than 1/10 the cost. Granted I can only cool one room at a time, but this means being able to get a good night's sleep rather than being miserable two months a year.
One other technical things I'd like to talk about: drainage. The act of cooling will draw moisture from the air. This unit gives you two options to get rid of it. For low humidity climates, it is designed to drip to a pan at the bottom of the unit. As the hot-side air is drawn over it, the water will evaporate again, pass over the condenser (hot side) coils and be vented to the outside. You *want* this to happen: moisture laden air holds more heat than dry air, and will pull more heat out of the hot side coils. Thus letting the moisture fall to the drip pan at the bottom and evaporate again will cool more efficiently than if you drained it off and let dry air pass over the hot side coils.
However, if too much condensed water accumulates in the drip pan, a float switch shuts off the compressor. Which happens in humid weather.
For mid/high humidity areas, there is a drain port halfway up the unit with a garden hose fitting. There is already plenty of water vapor in the air for heat transfer: no more is needed in the drip pan. Thus you should just drain it: I took a hose fitting and a meter of clear plastic tubing and ran the drain output into a glass jug (see attached photo). In two evening's use, I got about 1.5 gallons out of it. (See other attached photo) That's almost 6 liters of water that was in the air making things muggy. I was amazed over how much water came out of the unit.
The remote is pretty nice. I can leave it on the nightstand and turn on/off the unit without getting out of bed.
One more thing, this particular model is also a heater (actually a heat pump). It can warm your room in winter, providing the outside air is above 45 deg F. It won't work as a heater in Minnesota, but can be used on southern California winter days to take the chill out of a room and where the whole house furnace would be overkill.
Now to deal with some of the objections I've seen in other reviews:
1. Size. It's 12000 BTU/hr, that's bigger than many/most air conditioners, but it is not enough to cool your entire house. It does make 200 sqft into a meat locker though. Most would agree that it should adequately cool 400-550 sqft.
2. Noise. Now that we're all used to whole house AC and climate controlled offices and cars -- where all the moving parts are tucked out of the way -- we forget that all that equipment makes noise. It's not quiet/silent, but it's not too loud either. I usually run mine about 3 hours before bedtime and turn it off. There is a timer so you can run it for an hour or two after you turn in. Even if I had to run it all night, I'd rather sleep with the fan and compressor noise rather than tossing and turning and not sleeping from the heat.
3. Water/dampness. There were a lot of complaints about the unit stopped working in humid weather. That's because the condensate could accumulate in the drip pan and the limit switch would shut off the compressor. The solution would be to drain the moisture from the upper drain port. The second water complaint was that the unit would leave a puddle on the floor. Again the same thing. The drip pan is just that: a pan. If you tip the unit, water will spill. (Don't ask how I found that out.) If you're not on a level surface, you may be spilling before the limit switch shuts off. If you have that much water production, maybe you should be using the upper drain instead.
4. Lights. This would be *MY* biggest complaint. They're pretty bright. In fact they keep me up at night more than the noise. Worse yet, there are no labels explaining what they mean. Which means RTFM if you're wondering what the purple LED means vs the blue one or green one. And you have no idea what the fan speed is or other indicator lights because they're all blue, just different positions for different settings. Not quite enough to drop my rating from 5 stars to 4, but close.

This AC unit is used in my office on the 12th floor of an older office building in downtown Cleveland, Ohio. In the case of this older building the HVAC is less than consistent, but the windows do open. Last summer temperatures in my office reached the high 90s on some days. As we are a business formal firm the sauna-like environment in the office was not conducive to wearing a suit and achieving any reasonable productivity. This year, with this AC unit in use for the past three weeks, the office has remained a comfortable 70F with low humidity - even on the hottest day we have had yet this year (93F).
Noise: 4 out of 5
The fan and compressor on this AC unit are a bit noisy, but I think that the noise level is to be expected as the unit has excellent air flow and cools & dehumidifies my office (about 200 sq ft) quickly while helping cool the rest of the suite (about 875 sq ft) too. With the AC unit running on high I have been able to speak on the telephone two exceptions - only twice have I had to switch the AC unit to a lower fan setting in order to hear the other caller(s) on the telephone. This with the unit about five feet from my desk. I have not had any issues with conducting face to face conversations in my office with the AC unit running on high.
Setup: 2 out of 5
Setup did not go was well as I had hoped. The dual hose system is nice and connects to the AC unit very well. However, the screws provided to connect the hose assemblies to the "window kit" were worthless. The hose assemblies popped out immediately. Also the window kit covers a maximum of 36 inches - my office window opening is 42.5 inches. With a little effort I was able to fix these issues. I used #6 stainless steel bolts, nuts and lock washers (all available at Home Depot) to attach the hose assemblies to the window kit that was supplied with the unit. I also attached a Lexan (Plexiglas) "extension" to the window kit (also with #6 stainless steel hardware) that was supplied with the unit. So the window kit works well now and has retained much of the adjustablity with which it was designed. I recommend stainless steel as the hardware will be exposed to the elements and non-stainless steel hardware will likely rust over time. The hoses are also reasonably flexible so I do not have to keep the unit directly in front of the window I use to vent the unit.
Maintenance: 3 out of 5
Although the hose assemblies are designed to detach easily from the window kit (a feature that was unaffected by my use of the stainless steel hardware) the hoses do not come off easily (or, in my experience, at all). This creates a problem if one wants to inspect or clean the hoses (say if there are insects in the hoses, etc.) as the hoses will not detach from the window kit unless the window kit is dismantled. Also there is a condensate tank in this unit (that was not clear in the description when I bought the unit) that is not easy to empty. The drain plug is all the way at the bottom of the unit at the back with less than an inch of clearance to get a pan (or whatever) under the plug in order to drain the condensate. However, today is the first day I tired to empty the condensate (I did this to see how much condensate the unit had collected - the condensate warning light was not illuminated) and there was hardly any condensate in the tank after three weeks of use. I see from the description of this model on other websites that the dual hose system allows this AC unit to discharge most of the condensate to the outside via the exhaust hose and from my experience that system works very well. So hopefully draining condensate from the tank will not be an issue in the future.
I am pleased with this AC unit and would recommend the unit to others.
