Whynter Portable Air Conditioner 14,000 BTU Dual Hose 500 Sq Ft ARC-14S | Built In Dehumidifier with Auto Drain, Cool, Dehumidify and Fan Modes, Cools and Dehumidifies Rooms with Easy Setup

I just purchased this AC unit 10 days ago and have had it set up for around 5 days. So far it's working great. It wasn't too difficult to set up. Took around 10-15 minutes in total. It cools the room better than two 8,000BTU Honeywell units I had previously working in the same room. It can be a little noisy when it kicks in, but honestly not that bad, and often it's pretty quiet. I like that it comes with a remote and a cover. I was a little surprised they recommended changing the filter every two months. That seems a little excessive unless you have the unit in a place with a lot of dust. The unit is fairly large, so expect that it will take up some space. It also works much better if you have both the intake and exhaust hoses hooked up and vented out of the window. I will say, the plastic slider that you can adjust for the window size was too large for the width of my window, so I had to trim about 2-3 inches off of it. Not a big deal, but if you don't have the tools to do that, it could be an issue. I haven't had any problems with it yet, but again, it's only been 5 days. I'll have to update my review if there are issues in the future.

Update: Now that I've had this for more than a month, I want to set something right. My first review mentions the compressor not activating unless it I set the A/C unit 10 or more degrees lower than the room temp. That was true, however, It turns out that there was a cold air draft hitting the bottom of the unit, tricking the thermostat in to thinking that the room was colder than it actually was. so that was no fault of the A/C unit. I have since corrected that issue and now the unit is spot on accurate. I have a weather station beside the A/C and it confirms that whatever temperature I set the air conditioner to, it keeps the room exactly that temp. I now like this unit more than ever, as the rest of my house can reach 85°-90°, whichever room I have this in, stays as cool as I can tolerate. So, to summarize, I love this unit and absolutely recommend to anyone who needs a portable unit that this is a great option. If the need should arise for another in the future, I will not hesitate to purchase another Whynter Portable Air Conditioner. I've only had this for 3 days but so far it is working wonderfully for my needs. I bought it for my bedroom that is only about 175 square ft. I have central A.C. but it doesn't work very well especially on days >85 degrees. It was simple and quick to install the hoses in the window and it comes with everything one needs for basic installation. The air gets really cold and keeps the room at a comfortable temperature, A little lower than what is considered perfect room temp as I like it cooler on scorching days. A couple things I have learned that may help others are: 1) The vent on top doesn't do anything as far as aiming the air because there is about a 1-2inch gap in front of it. I know that it's like that so when the vent is down, the air can still blow out but it lets all of the air out of that gap and none really blows through the vent. To fix this, I filled that gap with weather stripping and it works perfectly. 2) Since there is a 5° cushion as explained in the manual, to keep my room at 70° - 71° requires me to set the A/C thermostat to 64° - 65° otherwise the compressor won't turn on until my room is really hot to me. and yes, I know that is more than 5° but I've been trying to get the optimal temp and settings for my comfort and have noticed that according to my digital thermometer that the compressor will not activate a lot of the times until my room temp is around 73 -74° and The A/C is set to 64-65°, so it's more like a 9-10° cushion. Finally, the quick start paper that explains how to run the hoses specifically states that to attach the end connectors to the hoses, you must turn clockwise but inside the manual, the exact same diagrams and explanation says to turn counter clockwise. The quick start guide is wrong, you must turn counter clockwise. None of the aforementioned things are what I consider problems just little things I've learned in a couple days and the A/C unit functions well and keeps me cool. Considering the cost, if it lasts several seasons, I will stay happy with my purchase and will definitely recommend. Should anything go wrong, I will update my review.

I bought this unit because our home AC decided to take an unscheduled vacation, and I needed something to keep the master bedroom livable while we sort things out. I have to admit, this thing impressed me. It cooled our master bedroom and bathroom in under two hours, which honestly felt like some kind of wizardry considering the heat outside. The cooling performance is absolutely the star of the show. If your priority is “make this room cold and make it cold NOW,” this unit delivers. That said, I’m giving it 4 stars instead of 5 because this thing is not exactly subtle. It’s big. Like “small roommate who only communicates through fan noise” big. And yes, it’s loud. Not jet-engine loud, but definitely “you will raise the TV volume a few clicks” loud. For a permanent bedroom setup, it’s a bit too bulky for my taste. But for my future use in the garage woodworking shop? It’s going to be perfect. In fact, once it’s surrounded by saws and power tools, it may finally feel like it’s among its people. Overall: excellent cooling power, easy setup, and absolutely worth it if performance matters more than silence or compact size.

[By the way, i add "technical explanations to this review and an additional comment i put in, but i recommend you find the response a much more knowledgeable person than myself added correcting my technical data, as he actually understands the mechanisms involved, and i offer all my "technical" speculations out of total naivete'] New notes, simply after owning unit through summer in los angeles: Unit still works great, as it did after 30 days when i wrote the clumsy verbose review below. the machine works AAA+. [November 2011, still works awesome and has been on, nonstop, since spring. Use it just as a nice fan to bring cool air into room when it's cool outside, also. Handy, if one needs to close the windows to lower street noise, for example, but still wants fresh air coming in. Works amazing for that just as amazingly as it works for cooling. Anybody have one of these units that also comes with the heat pump? i'd be very curious how well that works. i would have bought one but Amazon didn't carry them and i wanted the extra guarantee of buying through Amazon as i was so nervous reading all the terrible reviews about every single portable A/C offered. (though there are very very good reviews also, but the negative reviews made me very nervous. but my unit, yet again, has worked awesomely]. [i think the ducting connections, where the duct snaps onto the machine and at the window, could be designed a bit better, and i hope they improve it, but my machine has been on 100% of the time since i bought it, day and night. Was almost 100 farenheit yesterday and it works great in my big studio apartment] So far this unit works awesome. I will also, below, explain the advantages of a two duct unit, and particularly the advantage of a two duct (hose) unit that has the capability to also act as a single duct a/c. That confused me, and i will explain the crucial significance of this below, and why I believe for myself and many people living in areas where it gets quite hot, having a dual hose unit that has the ability to switch back and forth into operating off only a single hose, sometimes, and a double hose, at others, is a HUGE advantage. Forgive some repetition below, i simply don't have time to edit right now, but thought i'd post this. maybe i'll clean it up later and simplify) it works totally awesome. the duct kit works just fine, doesn't fall out of the window like i think some reviewer said, works great. However, it is the ducting and where the ducts join the fittings in the body of the air conditioner which seem the poorest made part of the c/c and one wonders why they didn't build it with a bit more precision. why in an expensive piece of equipment go a little cheapie at that point, i.e., the fitting of the ducts, which does not fit perfectly, but still has worked functionally perfectly for me? i guess because in one sense this is an expensive piece of equipment, but on the other hand it is not that much money $450 is what i paid, but even at $600 or more, for the amount of equipment in this substantial serious air conditioner. My very high quality Epson inket archival printer cost about $1800 and was worth every penny. This air conditioner looks every bit as complex and substantial to build, so especially at $450 to $650 or so, they probably have to cut costs where they can, as well as "exploit" (in the good and also the bad senses) foreign labor, such as in China. again, it gives "work" and income to China, which is good, but might be reinforcing paying their laborers very low wages and then obviously has heavy impact on our own national labor force... but let me sidestep these issues, simply to say it seems like a lot of equipment for the money. i've noticed a few possible glitches happen in 30 days, but nothing consistent enough to report, and i will try to buy one of the extended warranties Amazon offers through Square Trade. i think that is probably a very very good investment. i hope the warranties are as good as most of their reviewers say. another thing i would say is that it is difficult for consumers like myself to make expensive decisions like this. it involves a lot of fear and stress. like many, i read tons and tons of reviews on all the air conditioners and there are a lot of bad reviews out there for every product, so it makes it all quite scary. in the area of photography, though, an area that i'm much more expert in, i see cameras that i know and use each day, such as my Canon Digital Rebel, getting a tiny percentage of horrible reviews along with the high percentage of good reviews, so i guess we have to find out what are rare malfunctions and what are typical. i've taken about one quarter million exposures with my camera and it works great, and yet there are people that have bought some lemons of the same model, and then others who simply were baffled by operational procedures (easy enough to be baffled), etc. and these latter small percentages give my camera horrible reviews. i am SO happy i never read any reviews before buying my camera as i would have freaked out reading the small percentage of bad reviews. do you see my point? there will always, i guess, be some bad reviews, and i think it is simply stressful figuring out if those people got very very rare lemons, or if those bad reviews mean one should avoid the product. on top of it, to me, it looks like there are a lot of fake good reviews on products written in stereotypical language. so it's confusing, yes? i recommend buying the extended warranty and i'm hoping they are good. anyone who might want to reply to this comment regarding the Square Trade Warranties, i would be interested. planning to buy one within a day or so on this unit. sorry for the consumer digression on these topics. BACK TO THE A/C at hand: so far this Whynter dual hose 14,000btu portable air conditioner works awesome. also it is not some horrible eyesore, but the opposite, it certainly at least appears strongly and aesthetically made. i always wonder about people talking about the aesthetics of these things... makes me suspicious that they are planted raves for a product, but it's worth reporting the machine APPEARS well made and similar in aesthetic impact to my $1800 Epson archival inkjet printer). Oh, REGARDING DUAL DUCTS: i think one thing to know on this, that baffled me: The advantage is that you can draw cooler outside air, or not create a negative pressure, whatever that is... The cooler outside air i understand and i like that. But I think ideally you want the DUAL DUCT UNITS THAT ALSO OPERATE AS A SINGLE DUCT UNIT, meaning you can disconnect the second hose or duct, the one bringing in outside air. (you never would disconnect the "exhaust" duct when air conditioning, as that is getting rid of the hot air produced by the motor(s)...) TO CONTINUE ON THE DUAL DUCT SCENARIO AND WHY HAVING THE OPTION TO OPERATE AS A SINGLE DUCT UNIT IS IMPORTANT: if it is scorching outside, let's say it's 110 degrees farenheit, but that inside the building or house it's 95 degrees farenheit, then you probably want to disconnect the outside air intake duct from the back of the air conditioner and put a cap on it that they provide, and on the duct you've disconnected. Then you are drawing from the cooler inside room air, instead of the superheated outside air. (they tell you to, and it is obvious, to disconnect at the back of the a/c rather than at the window... you can do both if you have two caps). THE POINT: you are then drawing your incoming air in from the room which is only, in this example 95 f. as opposed to the 110 f. inferno outside. thus the machine only needs to cool air that is 95 f., not 110 f. which might be (or likely is) pushing these machines past their limit. they only claim to cool down max temps of 95f, i think on this Whynter, and the parallel Edgestar machine i think says 90 f. i chose the Whynter after much going back and forth). So you try to intake air from wherever it's the coolest air in a high heat scenario. if you get home at the end of the day, and left your a/c off, and it's beginning to cool a bit outside but it's still 95 to 100 degrees inside your house and then your going to cook on the stove on top of that, you want to DEFINITELY be ducting your air in from the OUTSIDE where it has cooled off. is that clear? if not feel free to ask me to clarify through replying to this, as i found it very confusing trying to figure out the pros and cons of two-duct systems as some reviewers fault them for having problems and i think the main problem is that if you are ONLY able to duct from the outside and you run into situations where it is, again, very hot outside (e.g. 95f +) and cooler inside, but you are stuck getting your air from the superheated outdoors. so, i made sure that on this unit, by researching and talking to their techs, that you could definitely disconnect the outside intake duct, and the unit would then take air from inside the room. Some dual duct units advertise this capacity clearly: Saying it will operate on one duct or two. Therefore, this is the obvious advantage of two ducts where you CAN operate off one or two. clear? hope so. good luck everybody. this consumerism stuff is high stress. Whynter 14,000 BTU Dual Hose Portable Air Conditioner (ARC-14S)

For anyone going back and forth trying to decide on a portable, you'll likely be happy with this one. I've had a couple of different brands similar capacities, and this one is the best of them, for a number of reasons: - Dual hose. All portables need to bring air in from outside to make up for the air fed out the exhaust, but with a single-hose setup, the returning air is coming into the room through door and window gaps, direclty compromising the cool air already in the room. When it's fed directly into the unit instead, it's handled more efficiently and allows the cool air in the room to stay cool, giving you faster, more effective results. - Runs quieter than other portables, the quietest one I've owned that's for sure. - Aims air at a high upward angle but can be adjusted lower if desired. If you have vaulted ceilings like I do, this helps cool a room more evenly. - The air coming out is very cold, colder than I've felt from similar units. The difference was immediately noticeable. - Lower power consumption than similar units. It's rated at 11.6A, which may cause trips on a 15A breaker in hot weather, so use a 20A circuit if you can. This will help keep the cord cooler and run more efficiently. Hotter wiring isn't only dangerous, they're more resistive and have to work harder to provide power. Run this unit by itself on a circuit to facilitate this. If you're forced to run an extension cord, do not skimp. Make sure it's rated for at least 15A/1875W and has a three-prong plug, and isn't longer than it needs to be, and no longer than 25 feet. - Auto-evaporates as promised - not a single drop has come out of the drain port yet, which can't be said about previous units I've owned that promised this feature. - Hoses exit vertically from the rear, allowing you to position it closer to a window. Even In my case where my hoses exit closer to the floor through the opening in a pet window insert in a sliding patio door, the hoses bend more naturally to this situation. Some things that could be improved, but by no means a dealbreaker: - Drain port position. If you live in a very humid area where the unit can't completely auto-evaporate and you get water out the drain port, it's positioned at the very bottom of the unit and limits your options for autotomatic drainage with a hose, which cannot angle upward because the water will pool in the hose and not drain effectively, as opposed to units where the port is up higher. Setting a drain pan under the port has limited capacity and forces you to dump the runoff more often. - No intake hose prefilter. At $25, Whynter's solution is an expensive additional purchase for what amounts to a bit of screen mesh embedded in the part you're already getting with the unit. For Less than $10 I bought an entire roll of aluminum patio door mesh and added my own. For another $10 I picked up some welded 1/2" square mesh to protect the exhaust port from outside critters. Additional tips: - Insulate the exhaust hose, either with DeLonghi's insulating sock or a 6-foot piece of R-8 insulated duct sleeving, found at big-box home improvement stores. - Use some duct tape to seal around the exahaust hose where it exits the unit, you will feel hot air coming out. Since it's a dual-hose unit, you don't have to worry about the crevices inherent to the window fixture hardware, but some foam tape along the interface with the window may help keep drafs to a minimum. - Set the temperature at least five degrees lower than your desired cutoff to avoid the unit from entering fan-only mode before you want it to. If your windows get direct sunlight consider a bamboo shade or blackout curtains, or better yet block your windows with foil-lined bubble wrap or foil-lined foam core insulated panels, to help cut down incoming heat.

Update: I had to send it back. Went to Lowes and got a lower BTU window unit. Easier install than getting the hoses set up in my windows with the Wynter. It did the job all summer. It will do, but I have to say, it does not blow air as cold or cool down the room as fast as the Wynter did. I did so much research before making this purchase. I learned way more than I ever wanted to know about portable and window ac units, amps the units pull, amps on a circuit, how to calculate amperage 2 hoses vs 1 hose, etc. This unit was rated highly, not only on Amazon but other websites and YouTube reviews. Long story short, I have the ac set up and running after way too many aggravating considerations, modifications and headaches. Good news is it cools my bedroom addition, that is not well insulated, beautifully. Larger footprint and sound are not an issue for me but it is pretty big and maybe 2x as loud as my air purifier? I like the white noise bc it is loud enough to drown out noises outside of the room, but not so loud I can't get to sleep. Now, the long story and multiple headaches. First hooked it up, kept tripping the breaker. In all my research on the product, I missed that they suggest the unit go on a dedicated circuit. Idk about you but my house is not wired with a bunch of, at least 15 Amp circuits (unit needs 11. something, lets round up to 12 amps) that can be dedicated to one appliance. Doesn't that kind of cancel out or at best, severely limit the portability? So, my not soon enough to be ex husband (Headache number 1) comes over, switches out the breaker to a 20 Amp, turns the unit on, texts me and says it's cooling. Great! Totally worth the headache of having to ask him for help, right? Um, no. I get home and only the fan is on. Turn the ac on, flips the breaker. Meanwhile, my favorite uncle got wind of my issue and is straight freaking out bc just changing out the breaker is a fire hazard. The Headache is all, "if you don't trust my electrician skills...." Not really bruh. You didn't even know how to test the ac my dude. Back to YouTube trying to make sure I don't burn the house down. It most definitely is a fire hazard because a 15a breaker uses 14 guage wire and the 20a uses 12 guage. You can't trust that just bc the wire guage at the breaker is 12 that 12 guage was run all the way to the outlet. So, without my xray vision spectacles, I have no way to know w/o ripping out walls or something. Hazard is because, if the various things plugged into that circuit go to pull more than 20 amps, any section ran and inspected for a 15 amp breaker could catch fire. Apparently, please dont take my word for it. Please consider consulting an actual electrician who probably doesn't want your house to burn down with you in it. Ok, what to do? Headache with his superior electrician skills, says only the bedroom is on that circuit. If I am not running anything else, it will be fine. Ok, make sure nothing else is running in the bedroom. Turn it back on flips the breaker and my son, in the room next to mine, yells out, "are you doing something mom?" Why? His whole pc gaming set up went off when the breaker tripped. Strike 2 for Headache's alleged "electrician skills." What to do? Check outlets and discover 2 of the 3 in my son's room are on the same circut. Locate, purchase, pick up a surge protector with a cord long enough to run all the way across his room to the outlet not on my room's circuit. Get that all set up, try again. Ac runs a while, it's cooling, no breakers are tripping! Perfect time to enjoy a nap in my properly air conditioned room! Settle in, get comfy, about to doze off....ac cuts off. Bad words are said, throw the sheet back go to get up and notice, there is a red light blinking on the unit. Look it up in the manual. Don't I remember something about that being missing from the manual from a review I read? Yep. Not there. Google to the rescue points to the drain tank being full. Why would the drain tank be full on my self-evaporation, no drain needed PORTABLE AC? Back to the manual. 2 possibilities, humidity is too high or loose wire. For humidity issue, disconnect intake hose from window frame so it is using air from the room, in my air conditioned, humidity controlled house. So, wait dual hose is better though, right? No time for that now. Drain the tank (not easy bc the drain is practically on the floor. And, I'm doing this by myself bc, remember, Headache doesn't live here, I hate asking for his help and now he is all weird bc my questions have apparently insulted his "electrician skills."). No worries. I am resourceful, find a collapsible bucket, tilt to drain. Try again. Not extremely humid in here, should be fine. No need to admit defeat to my makeshift, questionable electrician who wanted to know why I got that instead of a window unit and wondered how it drains (still appearing a bit cocky when I assured him I know condensers do whatever it is they do and water has to go somewhere but this unit is self-evaporating). Runs a while, turns off, red light flashing. Did this cycle with draining a few times...got old quick. Ok, not the humidity then. So, loose wire. Manual says contact customer service. Must be pretty common since it is in the troubleshooting guide. Reassured bc there is a warranty. I'll be hot flashing in a nice, cool, refreshing 68° instead of 80° in no time. Sent the email a week ago. No word yet as to what to do. Contact Amazon 3 days in, still in their 30 day return window but it took a hand truck to get in the house and the box is almost as tall as I am. Guess who I have to ask to help if I have to send this thing back? Yup, Headache to the rescue, full of smug, "I told you so," no doubt. Amazon did offer 30% discount, if I keep as is, which doesn't impact the warranty. I elected to wait to see if iI hear back from Wynter. Meanwhile, said self-evaporation, portable, dual hose unit on casters, is atop a strong acrylic storage box I had, with a child's stepstool cramed against it that is somehow keeping it from rolling so I can keep the plug open to drain it and empty the water about every 2 hours. 2 stars because it is running, cooling my room and Headache, the wanna be fire hazard creating electrician, doesn't know it is not evaporating properly...yet. Wynter, please email me. I will plan to update whatever inconvenience happens next. Cannot recommend as is and it pains me to say, but Headache may be right....the window unit may be the better option. At least it drains outside (I guess?).

It used to be my apartment was the same temperature as the outside, no matter what. When it was in the 80s here, that was doable. But as it climbed towards the 90s... and even 100s...! It just was intolerably hot! I added blackout curtains, and that dropped the temp 6 degrees between inside and outside. Now that I’ve got this AC installed, well, you can see for yourself from the picture— 20 degree temperature difference between the outside and inside. When it’s 105 outside, that’s the difference between “I can see the a**hole of the sun” and “I can sort of move around and do things today”. A few things to note: Setup: Yes, it’s fairly difficult to setup the first time. The unit is “portable” in the sense that you can take it with you when you move houses, but I wouldn’t so much recommend moving it from room to room throughout the day. The connectors between the window kit and hose, and hose to AC, are fiddly and difficult to detach and attach. They somehow require far more force and far less force than you’re expecting, and the accordion hoses fall off the exhaust pipes fairly easily. So if you can set it up once and leave it alone, that’s the way to go. The unit also has to be on a hard surface (not carpet), which I didn’t see mentioned anywhere. So putting it in a carpeted bedroom, is not a good idea. I set up a little hard-surface pad for it to stay on in my bedroom, but it’s a thing to note. The window kit is kind of a bear to deal with as another reviewer mentioned; it’s just not user friendly. If I were rating just the window kit alone, that would be 2 star— because it doesn’t have that many size windows it can fit. There’s a certain sweet spot of window opening size that you really can’t fit no matter what, unless you take a saw to it and change the size “manually”. Which then would mean you couldn’t reuse the window kit again if you moved it to another window... You’ll see I ran into that problem when installing it in my bedroom; the “wings” of the window kit were too short to use just one, but too long to use both... so I had to remove the snap-fit tubing for the intake hose, and fill that hole with a towel. Yeah... just some more work needed from the design aspect on the window kit. Size: keep in mind that the unit has to stand out away from the wall and window a little bit, on account of the exhaust and intake hoses needing room to get to the window kit. So if you’re trying to fit it into a tight space, add maybe another 6 inches to the “depth” in your figurings. The instructions say to make the hoses as straight and short as possible on their way to the window, but if I were to do that I’d have to pull the AC way out from the wall, so I elected to let the hoses be curved to get back some floor space. This unit is heavy. It’s about all the weight I can lift at once. The wheels on the bottom do a great job for helping get it from place to place, but if you need to get it up stairs, it’s a two person job for all but the strongest. Cooling: This is where the unit really shines, and what still earned it a 5star from me even despite the design challenges of the window kit. At the end of the day, you just need the AC to do one thing: cool. And I think this thing has great performance, especially for a portable. I don’t have any points of comparison besides central AC, but the Whynter has kept my apartment 20 degrees cooler than the outside, on what I can only hope is the hottest day of the year. This is even having it set up without the optional insulation wrap on the exhaust hose. The exhaust hose does get HOT on its way to the window. Not hot enough any kid would burn their hand, but hot enough I’m sure it’s affecting the overall cooling of the unit. I do plan to add the insulation wrap soon, just to see how it changes it. My apartment isn’t simple to cool, either: it’s very elongated with rooms off a main hallway that runs the length of the house, so the AC has to move all that air from way across the house to get things cool. That being said, the unit does have some limitations in terms of air circulation: I do have an oscillating Holmes fan running In front of it to help boost the air output. That alone helped with a two degree temperature drop. Customer Service: I noticed some other reviews mentioned a hard time getting in contact with Customer Service, but I found them pretty easy to reach and friendly! I thought my unit arrived without an instruction manual, but they helpfully pointed out that it was actually inside the exhaust pipe, which I would never have thought to look into during the first steps of installation. Customer Service was quick to get back to me and met expectations!

Works great to keep the garage cooler than outside during hot desert summers. At first it was blowing intermittent cool and warm air, which caused a bit of concern. We were using both the intake and output Hoses. The air outside was way too hot, so the AC had to work too hard. We ended up reading the instructions and they suggested only using the output hose on extremely hot days. So we removed the input hose and the air cooled instantly by using the cooler air in the garage. We use a stand fan to distribute the cool air more efficiently.It works perfectly. Great buy.

Excelente producto. Funciona muy bien, es silencioso y enfría las habitaciones rápidamente. El proveedor es uno de los mejores con los que he tratado en Amazon: responde de inmediato, resuelve tus dudas y supera las expectativas para garantizar tu satisfacción al 100%. Altamente recomendado.

I had a Danby 11,000 BTU single hose unit. Since it was a single hose unit, it was not very efficient and I saw that by the amount of power it used for cooling. That included creating a gap below the window exhaust kit to allow for the outside air needed by the AC to compensate for the negative room air pressure it would create. And minimize the distance that the outside air had to travel. The Whynter 14,000 BTU has been set up at the bottom of the stairs to blow air up towards the bedrooms. The deflector on top of this unit blows the air high, so it works on getting some cool air upstairs, while at the same time, keeping the main floor cool. It is an open stairway. I have a smaller AC in one of the bedrooms upstairs, but it's not powerful enough to keep the entire upstairs cool. I added a little bit of foam board on the section where the slider is, to complete the seal, as well as foam weather strip tape on the main exhaust plate. I taped over the open screw holes in the window kit and put a towel over the exhaust hose for now to help insulate against heat. I have ordered Reflectix Spiral Duct Wrap, which will replace the towel. To monitor the power, I have a TP-Link HS110 wifi power outlet. The unit is as quiet as I would expect for this kind of unit and a little quieter than the Danby unit we replaced when the compressor is running. I bought the unit when it was at its lowest price this year, which is still higher than other brands. However, having a dual hose unit is really the way to go to prevent negative air pressure, which means the AC will draw outside air from somewhere. It isn't Energy Star, but the power it draws is reasonable for its size. The EER is 11.2. It would be nice if it had an auto fan setting that would have it run low when the compressor isn't running and then speed up once it kicks in. Overall, the Whynter AC units are highly rated and it is well worth it to buy when it is discounted. At $790 without discounts on Amazon.ca, it's too steep, when compared to $453 US, which is roughly $600 CA at current rates. Keep an eye on it being discounted and you will have a good buy. *** Update *** Since my initial review, I have added the Reflectix Spiral Duct Wrap to the exhaust hose and a small piece on the adjustable window slide. I also added two 8 inch x 25 feet of flexible duct with a blower in-between to get air to our master bedroom. I am very impressed, as it is now as cool in the bedroom as it is downstairs. This AC has had no issues with keeping our whole house cool and it's like we have central air in the bedroom, as you don't have the noise of the AC in there. I'm impressed that 14,000 BTU could cover close to 1000 sq ft of living space. Thank you to other reviewers for suggesting the Reflectix and putting a divider between the intake and exhaust on the outside. *** Update 2 *** This summer has been both hot and there has been an air quality statement due to forest fires in the area. So these past few weeks the windows have been closed and the AC has been running 24/7. I purchased the Antimicrobial Filter and used it along with Carbon Filter to keep the air clean in the house. I'm very glad I have this dual hose system, so that it isn't causing a negative pressure in the house. My allergies have been kept in check and the house has been an even temperature. One other thing I discovered is that the AC will come back on with the previous settings when I use the TP-Link Smart Plug to power it off and on. This way I can control it to go off at night and on in the morning when the nights are cool. This was an unexpected bonus.

Product arrived damaged, sold with US plug in 110v and 220V to EU plug adaptor. Product does not work when plugged with the provided adapter. Does not start at all. Requested a refund, waiting for shipping instructions as this is a very heavy product to return.

Context : My previous window AC broke, a 10K BTU that was one of the best in the market at the time I bought it. I was moving in a bigger apartment that wasn't as easy to cool down because of the way the rooms are placed. After a little research to find the best portable AC, I had decided on this one. I've been using it for a few weeks now and I LOVE it. I'm seriously considering getting married to this AC. It's one of my favorite thing I bought this year so far. I was a little worried since I like to look at the stuff I buy, try them in the store and stuff like that, mostly on expensive stuff. And since it's heavy, I didn't know how it would work to return it if there was an issue with it. Also had very bad luck with portable AC in the past. But this one is awesome. The dual hose make it so that you don't loose as much BTU power as with other portable AC. It's very easy to put together, and I didn't even really sealed the area around the smaller slider thingy because I cannot be bother about it, but it still works like a charm nonetheless. And we've been having some heat wave lately, but I feel fine and cool. I mostly let the AC in my by bedroom, and even then, with a fan, I can redirect easily the cold air in the whole apartment. The apartment is ~620 squart feet, I have 9 feet ceilling. I mostly close the bathroom and the hall though, the hall is maybe 12 square feet (very small) and the bathroom around 45 square feet (anyway, once the bathroom is cool, it stays that way for a long while). My previous AC couldn't cool down more than ~350 square feet. Also, I love the fact that it can go lower than 64 F, even thoug the room feels a little hotter than that, it's still very nice and cool for me. So you really don't loose much BTU even if it's a portable AC. As for the noise, it's perfect for me. The cooling device makes as much noise and the fan made on my previous AC. So I sometimes wonder if it's working properly because I think it's only the fan when it's the cooling mode that is full on. And I always put the fan at the highest power too. Also, for me, it's good that it at least makes a little noise because it works as white noise when I sleep, so I don't have to hear the neighbors. The only thing I'm still worried about it the draining, but so far, I didn't have to do it. Thing is, the plastic plug that is on the draining hose on the unit is very very hard to open. Will see when it comes to that, and if I have issue with it, I'll come update this review. TL;DR : buy this portable AC, it's a marvelous device, 10/10 would buy it again

This thing performs. Here's the deal: If you can fit a window AC unit, go that route. THey are way more efficient and they will save you money in the long run. This portable unit (and all other 14,000 BTU portable units) perform close to a 7,000 window unit. Now, as far as a portable unit goes, this one is fantastic! It came with everything it needs and long enough hoses to connect to where I wanted. It does have its flaws. Pros: Cools fast. 1 hour full blast dropped my 400sq. foot bedroom 10 degrees Celsius on a hot day. It works! Multiple speed fan. Great for cutting some noise... and I do mean SOME. Semi-directional vent 2 hose (big plus for the high flow of this unit) Carbon filter (we have smokers all around us in our apartment and the smell stopped with the carbon filter. If you have odd smells around you, pick up an extra one. One filter lasted the hot season). Cons: Loud. When it kicks in during the night, it wakes us up. When the warranty is up, I am taking it apart and seeing if I can sound proof it more. When the compressor kicks in, the fan goes up as well creating an even louder noise difference even with the fan set on 'low.' Then when the compressor shuts off, the fan goes back down to low again creating a large change in noise levels. Almost as bad as the unit turning on. The LCD screen does not dim at all. I have to cover it up with tape. I thought this would tick me off but really, not a big deal. Once the warranty is up, I will be disabling the light. Directional vents are pointed. You get the option of Up, More Up, Even More Up, or Uppest. Forward would have been nice. Negative pressure. This unit pumps a LOT of air (a good thing). Even with the 2nd hose, we were getting some negative pressure. In a sealed room, I was getting headaches until I added a small breath hole in the stripping of my bedroom door. This will not be a problem for most. 1-track response. I contacted Whynter about the LCD screen light, the negative pressure, and the noise. The responded about the Negative pressure and nothing else (a VERY bad habit of companies these days where they read the first item in an email, respond, and ignore the rest). I wrote back to ask about the other issues and never received a response. Their phones are always down. That is not to say there service is bad. In fact, they responded the first and only time within 3 hours of my morning email to them. Bottom Line: This is a unit I would get for a place that does not need silence. It is a very good unit and out performs most every other unit I've seen out there (and I have used many with a south-west exposure on the top floor of a condo building). I tried once, just to see, if it could cool my whole 1000sq foot place. It brought the temps down 2 or 3 degrees but it will not handle that size of a condo. If you are looking for an office AC unit or daytime use only unit, this is your machine!
