I have a quad level (4 level) home that is 3600 sq ft and has a huge sun room. I bought one of these initially for the sun room years ago and the Ac works very well against the hottest days. A stand up swivel fan helps distribute the air more efficiently. The heater in the sun room kept up until it gets to the forties or below outside because it is not insulated. However my central AC unit died and instead of paying 8k for a new one for the size of my house I bought 3 more of these for less than $1500 and put one on each level. Now I have much more control over the temperature around the house individually. If we are not on that level I barely run that unit. It saves tremendously on the gas replacing the house heat and the electricity replacing the air conditioner. Plus every one can set the house level they are on at the temperature they like and no one is complaining how one level is uncomfortable because we try to get another level just right using the central air system. However a couple things to keep in mind. The units do dehumidify while running so it will generate some water at times that you can have collected in a bucket or as in my sunroom I drilled a hole to the outside an let it continuously feed outside. Also this has to feed the exhaust out a window. It gives off hot air when running the AC and cold air when running the heater. Here is my set up for the 4 units. The finished basement is large and has a separate laundry room. During the summer it stays cool so no unit is down there. It comes to the top floor and is used to keep the kids rooms cool. You can hook it in one bedroom and use a fan to blow it into the other rooms. During the winter this unit is in the basement for heat. Switch the drier to feed the heat inside through a filter I found on Amazon and I adapted this unit to exhaust through the drier vent. The water drains through a plastic hose to the floor drain in the laundry room. I had to get more drier hose for this to reach outside the laundry room and sit in the finished area. One unit each is kept year round in our master bedroom with bathroom and on the 2 middle floors for heat or AC. During the winter the kids rooms use portable ceramic programmable heaters. This set up is saving a lot of money. Also the units have on/off timers that I set while we are gone to go off when no one will be there or come on a couple hours before we get home so each level can be where we want it. These newer units I bought this year barely generate any water. The older one generates a lot more. I highly recommend this product.

UPS driver brought it upstairs. It as easy to set up. The vent tube is amazing! I let it sit unused for 24 hours, so the working fluid would settle. The plug has a button for reset, when pressed, it works. I plugged it into my Ecoflow power station Delta 2000, with solar panel in the window, and the heat pump works fine. It has a nice fan which make a pleasant breeze in the room, cool which cools the temp, heat which heats the temp, and the temp is easy to set. It uses about 1400 watts to work. I don't like the dehumidify, because it cools the air too cold, without me being able to limit it. Now the vent tube is a little tricky so here is my advice. I failed to use the little plastic screw to fasten the two panels of the window covering; I used a metal screw; but it worked. The foam insulation doesn't wrap around the edge of the window covering real well, so you might want to order some foam with a strong adhesive about three or four inches wide, and long enough to all sides of the window panel. Moreover, my bedroom is now wonderful, so much nicer, cool, warm, just right. I love the heat pump. It cost less than some purses you could have bought instead, but it's another example of Chinese expertise in design and manufacture. A big hug to the Chinese people.

I don't usually write reviews, let alone one this detailed, but since this is a high ticket item, I figured I'd put in the review. Hopefully it helps someone else make their decision. To briefly summarize the review below up-front for those that don't want to read it: yes, so far, i recommend this machine. I did a LOT of homework before settling on this unit. This is not my first portable AC unit, so I'm really really picky about the one i did get based on past experience. I don't live on a ground floor, and hauling this thing up and (in the event of a return, down) the stairs is not fun. I wanted something that minimizes that hassle. I read a ton of reviews on so many different companies and machines it felt like i was never going to find the right one. Everybody had such mixed reviews. I spent months looking for the right replacement unit. If i'm going to drop north of $400, because of the cooling capacity i need, it needs to be a really good machine. I needed a unit that would cool most of my apartment, so at least 500sq feet. (it's a poorly insulated/vented NYC apartment in a pre-war building. There's only so much a properly sized unit could do at best, so I'm not expecting miracles.) I didn't want an energy hog, or a machine that sounded like a jet engine. I wanted a company with responsive and good customer service in case things break or the unit arrived damaged. (AC units take a beating in shipping, in my personal experience, so customer service is important) I didn't want a machine that i had to drain or drain frequently (and had hard-to-reach drain ports and a small tank, or worse, leaked). I didn't even want (or need) a machine with a heater. And I definitely didn't want a machine that died after a few months. There are a lot of horror stories out there, and a portable AC unit is not an item that's easy to pack up and return. And then i found this machine, which had glowing reviews, not just here, but a lot of other places, and consistently (not just the most recent reviews). Plus the deal for the unit with the heater was too good to pass up. I bought it. It even arrived a day faster than scheduled. In fairness, i've only had this unit up and running for a few days, however, it is doing really well. It arrived in packaging that was a little worse for wear around the base, and thankfully, the packaging took the brunt of the damage. The unit itself was fine once i unboxed it. It is pretty hefty and bulky, so make sure you have help if you need to get it up stairs. I let it sit for a few days after it arrived to let the coolant settle before turning it on (as you do with refrigerated units). The user manual recommends letting it sit for 4 hours, but I don't think that's enough. Usually 24-48 is standard to let everything settle before hooking it up and powering it on. It's very important to let it sit though, or you will have problems with any AC unit if you turn it on right away without letting the coolant settle. It won't cool and it could damage the motor and internal mechanisms. I feel like that's usually the issue when i read reviews of units not cooling (or not cooling enough, if room size/cooling capacity wasn't the problem) Thankfully, there's no rush because it's winter, but I did want to catch the 60 degree day to just test how it would cool. The only reason I'm giving it four stars instead of 5 was that i had to take a hacksaw to the plastic window extension piece and cut several inches off of it to make it fit, otherwise i wouldn't have been able to get the exhaust tube in because of the overlap. And, also, there's no grated cover for the exhaust hose at the piece, so unless you put your own netting, things can get into the open exhaust hose. (or if there is a grate, it didn't come with the machine) It rolls pretty easily, and is relatively quiet. It is, after all, an AC unit, so it will be fairly audible, even at low speed. That being said, it's quieter than previous units I've owned. Now, because I've only had it for less than a week, I don't know how it does on power consumption, or, obviously long term. I am eager to see how it does in the summer. All i can say is that it keeps the notorious NYC radiator heat at bay really well, for now. It noticeably cooled my living room on that 60 degree day in less than 20 minutes after i turned it on. And I did not wake up in the middle of the night in my own sweat from the radiator heat in my bedroom (sorry, tmi). Those are both wins in my book. Fingers crossed this performance keeps up, because if it does, this is a solid machine.

I purchased one of these Dec 22, 2015 and paid $638.59!! It still runs perfect to this day. I used it it to cool my master bedroom and various rooms in my home during construction and the AC unit had to be removed. Ity saved our lives and sleep and basic comfort. I used it many times when the carpet was cleaned to remove the water and humidity from the air which helped the carpets dry significantly faster. I have a home office that in the difficult months of summer, that room gets baked and is 20 degrees hotter than the balance of the home. This thing is a life saver. Never a single problem ever and its been in seasonal use, mostly, for almost a decade now! It has been a very reliable. I purchased a 2nd unit for my Father in Law as a gift because has no central cooling and there have been extremely hot and humid weather. He would never have purchased himself so we got it for him in August 2016 (price was $499 then). It also has been running reliably since then and it is the ONLY AC he has. It has been a life saver for a Senior Citizen running every summer and during any high humidity times due to storms on the coast in San Diego CA just north of the border. Highly recommend this unit.

**UPDATE I have tried getting in touch with Whynter customer support by phone 4 times, their automated system hung up on me ALL 4 TIMES. I have written 3 emails and have not gotten any response. My unit will not sit level due to one of the casters being damaged in shipping. All I want is a replacement caster since the casters are not a standard size and I can not find a replacement anywhere. While their product seems to work well their customer service is dismal at best. Good luck with any issues. * I ordered two of these units. One arrived damaged, broken caster. I have emailed Whynter with pictures to try and get another caster but they have not responded. I dont want to send the whole unit back I just want a replacement caster. My only other complaint is that the exhaust hose is 5 1/4 inch diameter, not a standard size. Basically this forces you to use their window exhaust setup which is of pretty poor quality. My plan was to cut through the wall to vent to the outside and use a dryer vent cover. Looks like to make that plan happen I am going to need to do some fabrication to make this hose setup work, there is no real way to use a standard 5 inch dryer vent hose with this unit. I am a bit disappointed with the lack of communication and the inability to use something other than their window venting system without a bunch of fab work.

This is the best unit I have found that gives PLENTY of range for average people that enjoy a comfortable sleep at night even all the way to polar bear preference of cool at night. It’s also great for use during the day. I have only really used it at night or when I’m cleaning. If you like a unit that is whisper quiet and gives cold air, then is unit is definitely NOT for you. If you are someone that enjoys the gentle sound of white noise, then this is the PERFECT unit for you! My personal preference is to raise the central a/c up at night to conserve energy and then have my own personal unit. This is a match made in heaven for me since I like to freeze myself out at night and bundle myself up under the covers. We keep our unit all the way down at night and it freezes us out and takes it like a champ doing it. We really like the other best feature of the unit which is the noise from the fan. It’s loud enough to drown out the home theater system on the other side of the wall, much like you would want to have at a hotel or something. We have also used the heat when it gets cold enough and it works perfectly. The a/c fan will stay on in cool mode and will NOT stay on in heat mode. Bottom line: if you like to freeze out at night or use the heat every now and then and love the sound of white noise drowning out all the nearby sound then this unit is for you. It’s been reliable so far except for part of the numbers in the temperature display don’t light up anymore. I have had this unit over 2 years.

Although the unit cools fairly well, it makes too much noise. I was very disappointed as I looked at so many to try and find a quiet one. It's very hard to hear the TV when it's on. Also when it arrived, the box was completely torn off. The delivery company said they're always like that. There was no foam or any protective packaging around it for protection. Just the unit in a box.

I bought an older model of this same portable AC/Heater a few years back when I lived in Oregon and needed to cool and heat a large attic bedroom. I did a lot of research first and found it worked great for both. Works great as a dehumidifier too. When I sold my house I left it for the next tenants. But when I moved to east Texas I found I needed another one to deal with the excessive heat and humidity here... and the cold this coming winter. I bought a 990 SF 1946 house that only has two little window ACs in the bedrooms and one gas wall heater in the main room. So I researched again and found this newer model with the combined hose, which I thought was a great upgrade. I don't really need the wifi technology, but it's a nice feature. You can use it easily either way, plus as a fan to circulate air and remove humidity. This solution again is perfect for my needs! It's attached to my old hung window and is working amazingly well in my large main room. It's super quiet and comfortable now. Having bought it twice now, I highly recommend it - especially if you can't afford an expensive new central HVAC or mini-splits just yet. Durability: Sturdy, strong, and well-built. Noise level: Very quiet - way quieter than my window ACs. Functionality: Works extremely well. Very comfortable now.
