If you can put a regular window AC unit in, then you really shouldn't buy one of these portable things. Full stop. A regular window unit is going to be cheaper for the same cooling power and also a fair bit more efficient because it uses the outdoor air to cool the condenser. It also puts more of the loudest parts of the mechanism outside, which generally helps with noise, at least at the margins.But window units don't work everywhere you might need A/C. For me, this was a purchase for my elderly parents and my parents now can't easily pull a heavy window unit in and out of the window at the end of the season. Where they live, they won't need to run it constantly all summer and so the fact that it is a bit less efficient is somewhat less of an issue.Installation was not particularly hard, but the design of the thing you put in the window and plug the exhaust hose into could definitely be better. I ended up having to get out a saw and cut/shorten one piece to make it fit, which is what they tell you to do in the instructions. Of course, once you cut that adjustment piece to size, that limits the size of future windows you can install the unit into easily. Since this is theoretically something you can roll from room to room, they probably should design a window mount that can adapt easily to almost any size window opening without tools. Instead, they seemed to want something a bit more solid/durable, but far less easy to shift into multiple, different-sized openings. I will say that they do at least give you enough insulating foam pieces and such so that if you are planning to just put it one place and leave it there for the season, you can get a pretty nice seal, even if you are only moderately handy. In most windows, you can likely achieve an installation that is not going to let in bugs, rain, etc. or rattle while the unit runs.I also like the fact that, for a reasonably powerful room AC, it isn't crazy heavy. I think my small window unit from a few years back is considerably heavier. You may still need two people to get it up the stairs, but it wasn't too bad to get it into the location where I wanted to set it up. Note that it does need a level floor, so if you have an older house without level floors, you are going to have to level it. I did that by cutting a small piece of plywood for it to sit on, and leveling that. See the picture for an idea on how to install this properly in an old house with very uneven floors.It is also fairly sleek and nice looking, and I like that the vent on top automatically closes up to keep out dust and make it look better when it is not running. There is only so much you can do for something the size of a dorm fridge with a big white exhaust hose sticking out the back of it, but I thought they did a nice job with the exterior design. The build quality seems good, no weird rattles or shaking, kind of what you'd expect to get from a big, established company like Honeywell.I thought the noise level was somewhat better than I was expecting, and is likely at least tolerable for a bedroom for most people. It is certainly not silent and on the highest fan speed it generates a lot of white noise, but I didn't find it excessively noisy, even when the compressor kicked on. Note that no matter what fan speed you put it on, it has to cycle through several different modes in order to regularly expel the moisture from the coils and so you will hear it flip back and forth between these modes as it runs. That might be distracting if you are sleeping right next to it, so it has a sleep mode that basically lets the temp slowly rise for a while and reduces the cycling to let you get to sleep, and only starts cycling after you are likely asleep. Probably better than nothing, but I'd still put it as far from the head of your bed as possible if you have to sleep in the same room with it. You can also set a time delay to either turn it off after a set number of hours or turn it on after a set number of hours, which is handy if you want to leave it off most of the day and turn it on just before you get home from work, etc.The remote control looks nice and has a big display on it, but its functional design is almost comically poor. The button to change the system mode is located directly below the temp adjustment, meaning that if you are fumbling in the dark to try and make the room cooler half-asleep, you have an excellent chance of turning the mode from A/C to fan only or into the dehumidifier mode instead. Because the buttons are tightly spaced together, I've now accidentally changed the mode, fully awake during the day, more than once. So yes, the remote does work, and all the functions on the main panel are faithfully replicated on the remote, even the ones you will never need or use a remote for. But clearly nobody thought about somebody waking up hot at 2AM and just wanting to knock the temp down 2 degrees in the dark, which strikes me as a kind of a core function for an AC remote control.Overall, I am fairly satisfied with this unit. It seems reasonably well-built, reasonably quiet and powerful enough for my needs. Yes, the remote control is badly designed but I didn't buy it for the remote. I wouldn't buy this for a unit you want to constantly move room to room, unless all the windows you are connecting it to are the same size, and even then I wouldn't be that excited to reinstall it in a new window 2x a day, even if, unlike me, you have level floors everywhere. I think it was a reasonable value for what I paid for it.
