Honeywell 9,900 BTU Portable Air Conditioner, Fan, and Dehumidifier, Cools Rooms Up to 450 Square Feet, Includes Full Window Installation Kit and Drain Tube, HM0CESAWK6

Bought this product on Amazon after reading many, many reviews. Shopped for a couple weeks and picked 4 I thought might be a good choice. This was the one with the highest ratings, and they all pretty much said the same thing. The unit was quiet, and it cooled very well. I work nights and sleep during the day and didn't want to run my house AC during peak hours, so I got this unit for my bedroom. My bedroom is barely 200 square feet, and this unit is more than double what I need. So instead of having a smaller unit that runs more and works harder, I got a bigger unit that can easily cool the space I have it in, plus could act as a backup to cool the largest room in my house should my main unit go down. I received the unit and inspected the box, there was no damage other than normal signs from hand-to-hand shipping. I'm a fairly strong guy, about 200 lb so I didn't have a problem getting this in my house. Unpacking is very easy, cut the straps, open the top, take out the accessory tray with remote, vent hose, drainage tube, and instruction manuals, and the main box lifts off the base. The unit has handles on either side so you can grab it to lift out of the base tray it sits in. I put the unit in my bedroom, leaving the plastic and bag on it, letting it sit for well over 24 hours the way you're supposed to with any compressor based cooling system that's been moved around and possibly laid down. The instructions are very simple, only 15 pages in the manual, the user interface is very intuitive. The evaporative feature runs automatically when the unit is in cooling mode, and you can use dehumidification only if you're simply trying to pull humidity out of a room and not cool it. Two things impressed me right off, one, the unit is very, very, very quiet. Even on high mode, it's less than half the noise of my quietest floor fan in my house. Even when the compressor is running in air conditioning mode, it is very very quiet. I set the unit up in my bedroom to test it, and stuck the vent hose out the window so as to not recirculate the hot exhaust air. I turned it on, set the temperature where I wanted it, made sure the door was closed in my bedroom, and turned fans to recirculate the air in the room. The air vent which opens automatically when you turn the machine on, vents out the top of the machine. You can change the angle to have it shoot straight up, or angle it down a little bit to cool a certain area if that's what you want. It brought the temperature down in my room almost two degrees in less than 15 minutes, and was not blowing directly on the thermometer. When the unit reached the preset temperature, the compressor automatically shut off. Once the temperature came back up to the set point, the compressor automatically kicked back on and the unit started cooling once again. This is exactly what you would want in a room air conditioner like this one. However, there are a couple things you need to take into consideration when buying one of these; 1- have realistic expectations. If you live in a small space and mean to cool several small rooms, set up fans to circulate the air. This is not a central air unit and will cool the local area very very well, but without extra fans to distribute the air the cold are will sit in a relatively small area. 2- I believe the temperature sensor is located right next to the exhaust hose which makes no sense to me because that hose gets pretty hot, almost 120 Degrees. It's not hot enough to burn you or damage anything, but it does radiate warm air into the room and since this hose is located at the back of the unit, this is warm air that will pulled back into the unit to be circulated throughout the room, thereby impairing its ability to cool the room as efficiently as possible. My suggestion would be, as other reviewers have said, buy some Mylar tape or mylar blankets to wrap around the hose after you get the hose in the window. Mylar will not radiate heat through its structure, but will reflect it back at the source thereby trapping it inside the hose where it needs to be to be vented out the exhaust hose to the window. 3- other reviewers have also stated that in order to have the warranty honored, you need to register the product right away so that is what I will be doing in a couple days. Go online to the website indicated in the literature to register the product for the one-year warranty. 4- I haven't put a kill-a-watt meter on it yet to see how much it draws, but when it kicks on the light in my room barely dimmed at all which leads me to believe this unit drawers between 8 and 10 amps. I haven't verified it yet, but the fact that the unit will cycle on and off plus the fact it cools very efficiently means it should not make a serious dent in my electric bill which is why I bought it in the first place. 5- have realistic expectations. This is why I gave the unit of five star rating, it does exactly what I needed to do, does it well, and doesn't do anything I don't need it to do. This may cool off a small apartment, or main room in a small house, or a large bedroom, but it is not meant to replace central air conditioning. If you're going to run the unit for long periods of time, read the manual and make sure that all preventative maintenance is done. By this I mean, make sure the air filters are clean as this is Paramount to the unit's performance and lifespan, also make sure that before you shut the unit off you allow the fan to run for about 10 minutes to dry up any humidity that may have accumulated on the evaporator coil. 6- This 10000 BTU unit is overkill, I think this is always a good idea when purchasing one of these. Buying a larger unit than you need will not severely tax it, like it would if you had bought a smaller one to save money, and have it run all the time only to have a shorter life span (and a higher electric bill). This is a good-looking unit with contoured body panels, a little unconventional if you ask me. I would also recommend inspecting the Box before you open the unit to make sure there's no significant damage. Although these units can be transported, they do not like the rough handling they sometimes receive when individual units like this are shipped.

I just received this unit yesterday. Setup was a breeze. The air flow is very strong coming from this unit. I ordered the 10,000 BTU for my one bedroom apt with a kitchen galley. This unit is very stylish and cool looking. Very quiet on fan mode but I think it is a bit loud on air conditioning. Not really bad but I think they can make this unit a bit quieter. To help the noise a bit I put a rug under neath the unit. So far I am very pleased with this unit. Still to early to see how it really runs on cooling. So far it is keeping my apt at the temperature I set. Blows very cold air which surprised me for a mid size unit. I will review again in a month. Update: Had this since last year and still performing well. No problems at all. The only negative is that it drains alot of water. Very humid in the summer where I live. I use a 2 gallon pail with the hose and have to empty at least once a day. Again all depends on how much you run this conditioner. I love the dehumidifer that is on this machine as well. Really takes out the moisture in the air. Just watch your drainage for emptying.Overall very happy with this air conditioner and would recommend buying. Make sure your buying the right size for the area you want to cool. I would buy again.

Upon taking the time out and doing the research this unit does deliver what it promises. We recently moved to a brownstone in Harlem in the spring and have it the master bedroom on top floor. That being said the bedroom faces where the sun rises and as you can imagine the house gets baked through out the entire day. Installing the window hose and over all assembly was a breeze (no pun intended). The unit’s dehumidification mode is superb on those humid days. We typically have the unit always running between the dehumidification mode and AC cool mode with our black out shades and it does cool the room within an hour. We typically start with the AC cool mode before going to bed (about 30 minutes to an hour) and then switch to the dehumidifier for overnight. We also have a dog and with the unit always running our throughout the day so the monthly electric bill wasn’t that high (def an energy saver). The unit paired with black out shades does tremendously help on those really hot days. Now with the dehumidification mode it does really extract the water in the room so having a bucket for the hose to drop into is highly recommended. The AC cool mode does also produce water but nothing compared to the dehumidification mode. We usually empty it twice a day on those hot humid days. As far as the noise level it’s pretty quite, our bedroom does face the street so the noise doesn’t really bother as much but it does fall into the white noise / background noise sound-range if your looking for some type of measurement. The only reason why I’m not giving the 5 stars is the fact that you do have to empty the water bucket but I guess it comes with the territory that’s hot humid nyc summers. For an overall solid performer it’s exactly just that.

1st, I live in Arizona and have a back bedroom that the house AC could never cool down enough when the outside temp got over 90. We debated over a window unit or this portable one and decided we'd like the option of easily moving it if needed (and a much simpler installation). Unit arrived on time and intact. Set up was a breeze, but NOTE: I highly recommend, as have others here, you add weather stripping after you have put up the window attachment; there were a few noticeable gaps the were letting in a decent amount of outside air. I got some of the 1" wide stripping and it easily filled in the spaces. Other than that I think it took me all of 5 minutes from unpacking to turning it on. Once it was running, it took no time at all to cool down the room, about a 20x20 space with high ceilings, much faster than I expected. An important note here regarding noise. It says its quiet, but lets be honest, its as loud as most window units I've heard but that's not such a big deal for me as I like the white noise while sleeping, BUT if you are sensitive to noise, just be ready to deal with some here; I think it's impossible to make a portable AC that's not going to make some noise, so be ready. Haven't had a chance yet to see the units impact on the electric bill, but I am expecting a bump, but for a comfortable night's sleep from June to September, I'm more than happy to pay. So far I highly recommend this if you're looking to cool down even a good size room and don't mind a little extra noise. Can't speak to quality as we've only been running it about a month, but lets hope it holds up as promised.

We used this to cool our master bedroom during the power outages associated with the two major hurricanes that hit this part of Louisiana Summer 2020. We hooked it to our generator. During both outages the temperature in the main part of our home reached the upper 80s. The bedroom stayed around 76 constantly running at 70. Did it keep us cooler than we could of been? Yes. But not like it should with only a 10 degree difference between our living room & smaller bedroom. I grew up using these types of units esp the 10K BTUs window units. I have to say for it only reaching up to the mid 80s in the rest of our home this unit closed off in our bedroom should have worked better. The manual says it comes with a heating function it does not. I was under the assumption that it did. I guess I didn't read the listing or they've changed the listing since I bought this. It is easy to put together but it's really not worth the money when you pay close to $400. A standard window unit at this BTU is close to $200 and most of the time they come with a heat function.

This performance of this unit definitely agrees with the other good reviews. I am using it as backup when it is too humid for my evaporative cooler to work well. I couldn't be happier with my purchase and my GSD really loves it. It is heavy and you may need help getting it into your house if you have to go upstairs or over a rough surface so be ready. You gentlemen will probably be ok but ladies, be prepared just in case. I was able to remove it from the box by cutting the top and one side open. The set up is straight forward and clearly shown in the book. The hose, seals, and inserts for your sliding window are inside the package. Yes the compressor makes a little noise when it kicks on, but I don't think it was overly loud or annoying. Turn up the volume on the TV or sweat-you pick. This unit can also be used as a dehumidifier, a fan, or a heater in addition to the AC feature. If this isn't enough, I would like to mention that the Honeywell is a nice looking unit and is A LOT more attractive than most portable units on the market. It will also be easy to keep the dust off and filters clean. A great choice and just what I needed.

This is our second Honeywell AC. Our first did not have any of there issues. While does cool down our bedroom for now, I’m not sure how it will work when it’s gets in the 90s. There are four things that make us regret purchasing this nearly $400 AC unit. If we still had the box, we WOULD go through the hassle of returning it to Amazon. Here are the problems: 1) When it is in COOL mode it is extremely loud. It has a high-pitched whistle/ringing sound that make it impossible to sleep much less focus while awake. 2) The remote screen is so dark (and does not light up). Its very hard to read what settings you’ve selected. At night we have to turn on a light to see the remote to know if we are choosing the right settings. 3) The direction of the air flow is pre-set and cannot be manually directed toward a specific area without turning the entire unit. 4) There is no drip pan to collect the water so we had to use a cookie sheet right under the valve to drain the water. It was a pain. Overall, the non-stop ringing sound makes this our worst purchase this year. :-(

SW Florida New Review: Use - less than a week. I am a window A/C user for decades. Our window A/C broke causing extensive water damage. "Let's try a new thing." A Honeywell was our choice! Conclusion: Pros: I believe this A/C would work more efficiently with greater consistency of temp, if used in a single-wide open living space. Con: Not perfect for "evenly" cooling two adjoining rooms connected by standard door (as we do have). Our adjustment - Enjoy living areas at perect desired temps throughout days - while dismissing warmer BR temps during day. Make use of blankets while watching TV during "transitioning" time of 3 hours between 9:00 p.m. - Midnight. Enjoy perfect temp for "falling alseep," waking up to turn on bedside as temps rise. . Here's our story. Pros: I am a handicap woman, and this was a SNAP to install. Literally, one end snaps into the unit and the other end snaps into the window plate. Window end "rotates" making "alignment" perfect without struggling to manipulate the hose for perfect alignment. Pros" Vent panel door opens automatically when machine is turned on, and air flows directly in front of machine. I can control air flow up to ceiling or down toward floor. Con: Machine is quite heavy - I won't be moving it around over the carpet. (Though I can "push" it a bit). Con: Machine is really wide / bigger than desired. Visually: Machine looks fine, but again big. The huge plastic, accordion "stretch" hose is n eyesore. Pros-The hose "crimps" back so you can minimize the length of hose to only what is needed. Pros- Because hose "stretches" it provides some control of machine placement. Noise Pros: More quiet than expected - More quiet than the new window fan we replaced it with. It does make "sound" but closer to low, dull, steady "humming," NOT like the noise of parts/motor rumbling, clanking, or "working hard" to put out. Pros: This A/C cools two adjoining rooms. It is positioned in our 25'x11' kitchen/living room and the A/C is positioned to blow air directly into our 14' x 11' master bedroom. Efficiency out put of cool air: Starts to cool immediately. Cons: We're still experimenting Living areas will get substantially colder than bedroom throughout day, if A/C is set and remains between 74-76 degrees (while outside temps mid-high 80s). We'll see when Florida tempts hit 9O - 100 how it performs. Con: Will not provide steady, consistency of preferred temperature throughout both Living area and bedroom (The window A/C did. A big window box fan is needed (in connecting doorway) to draw cooler air from LR into BR. Pro/Con: We have learned to set the A/C down to 70 degrees around 9:00 p.m. to cool down BR for sleep around midnight. This makes the living area "cold" and we need a blanket when watching TV. I've learned that if I leave the A/C set on 70 throughout the "night," the bedroom gets "too" cold and I wake in middle of night. Hmmm. Compromise: I have set a small 10" fan on bedside table. Just before hoping into bed, I turn A/C back up to 72. I can sleep a few hours but start to toss and turn around 5:00 a.m. cause of rising temp. I turn on my little bedside fan to blow directly on me, and I am able to go back to sleep.
