5.0 out of 5 starsGreat unit but you must understand how these units work and buy one size larger than specified
Reviewed in the United States on August 26, 2012
I've had this for almost two months now, having made an "emergency" order during the middle of one of our Summer 2012 heat waves in Chicago when my bedroom window unit finally gave out. It has fully met my expectations, but expectations are the key concept. You must understand certain things about these units before ordering:
1. They are noisy. All the mechanicals are now inside your room, not outside your window. I got used to it and have no trouble sleeping, but I am not a light sleeper. Consider your own sleeping styles.
2. Many of these units require drainage or emptying a water collection tray. This unit does not. It has a great way of evaporating the moisture it collects back out through it's exhaust. I have never had the unit stop due to it being full and it runs 24x7.
3. You must have a way to vent the unit by connecting the hose to the supplied window insert. I had just enough room left above my existing window A/C to insert the supplied frame for the exhaust hose. This configuration takes up space. Plan for the unit and the hose setup to take up room!
4. As many other buyers have pointed out, you cannot compare BTUs of these units with that of window units. I took the advice of others and bought a unit one capacity level ABOVE what I thought I needed and I am very glad I did. If I had bought the unit that said it will cool a room the size of mine, I don't think I would have been satisfied. Yes, they are expensive, but buy big or be unsatisfied.
Installation:
Installation was ridiculously simple. The box was structured such that after cutting the straps, the whole box top and sides lifted right off of the unit. Once out of the box, the pre-affixed wheels made it easy to just wheel it into the bedroom. The hose and window insert were easy to install. There is one design flaw though, inherent in these units. They place the fresh air intake right by the exhaust hose exit in the rear. This means the unit competes with itself to cool the air, because that hose gets HOT!. Simple solution though. Buy insulated duct wrap at the same time you buy the unit and wrap the hose in it from the back of the unit to the window. Or as a temporary measure, wrap the hose in bath towels, especially close to the unit intake, to reduce the heat produced by the exhaust hose.
Operation:
I turned the unit on after plugging in and it fired right up, producing cold air. It's not freezing cold, like older window A/C's, but it is cold. It took about an hour to take the room from 87 and 60% humidity to 76 and about 40% humidity. Like other buyers, I do find the limited movement of the air output louvres to be annoying. You can only move the airflow form side-to-side, not up and down. If you have a high bed, you'll want to consider raising the unit up onto something, preferably something very sturdy. It has three fan levels, but I usually keep it on low. The remote works well, but no light so you may have to use a flashlight at first until you memorize the position of the buttons by just feel.
One thing I haven't tired yet that I do plan on is running it as a fan in the winter. I like to have background noise when I sleep. You can run the unit in fan only mode without the exhaust hose being connected. It's the dehumidify and cool functions that require exhaust to the outside. The fan alone, without the compressor, is actually very quiet but just noisy enough for steady background noise.
Efficiency:
It claims to be energy efficient and uses an environmentally safe refrigerant. I have to say that it does cool well (as long as you understand you probably need one unit size larger than recommended) and it does seem to efficiently evaporate all the moisture it collects out through the exhaust (there is a fan that stays on constantly to ensure this). But when I got my first electric bill after running 24x7, I knew it was efficient. My energy usage declined by about 25% year over year, with this unit plus another window unit running versus two window units. And that was during a month when it was hotter this year than last.
So all in all I am very happy with my purchase. But understand how these units differ form window units and buy one size larger.
