      Very good job of cooling, tricky installation

      • My Best Buy® MemberMember

      The environment were using the unit in: Our Late 60's condo (top floor) so our ceiling (made of solid concrete & no insulation) becomes radiant as the day progresses. Meaning by 2:00pm the ceiling temperature will radiate 82 to 92 temperatures. Measures by thermometer attached to ceiling concrete (justifing installation of surface insulation in future throughout condo.) South Florida Humidity is generally 75 to 85%. Installation: Unit comes with 5 to 6' accordion hose (when fully expanded made of semi-rigid plastic) There is also a window insert with 2 openings (one for hot air exhaust from the air exchange. So unit brings in air from outside keeps it within the unit and then exhausts the hot air taken from the coils to the outside. (this process occurs fully outside in a wall unit or in the outside box unit of a central AC) The plastic insert has 2 side panels that allow the unit to fit many windows. Unfortunately our's was way too big (again a function of a 60's condo in florida) I was able to use some foam to fill in the gaps until i could go to the store and buy a piece of wood that would bridge the gap and some foam to seal the window (this is going to be there at least for 3 or 4 months and I don't want to have it leak air if i can easily prevent it. So I cut holes for the 2 hoses and attached them to the wood board, the board was already but to length at my big box home improvement store and a little drilling and i had the hole cut out. problem solved and installed. For less extreme environments the included kit will work in many climates. Results: Last week was our first real bit of heat for the summer which ended the week Thursday (low 75 high 87) and Friday (low 74 high 92) and the ceiling radiating down 85 on Thursday and 90 on Friday. With that the unit keep the temperature at 77 all day at desk level (also have a thermometer on the wall next to me) as i look up right now the ceiling is at 90 and my level is at 76. So as a result I can work my 10 hour days and not pass out from the heat! The unit also takes a lot of the water out of the air but I have yet to need to drain the unit. Maybe being somehow vented in the exhaust air exchange? Unit does have a remote control (all the adjustments are done with the remote) which is essential because there are just basic controls on the unit (Unit On/Off & LED On/Off) Presumably to keep little hands from changing the temperatures, etc. As I noted you can TURN OFF the Led light so it won't bother those who are kept awake by other bright LED's in a bedroom (or if you just ind the lights distracting) Cold Air exhausts from the top of the unit in a basic 180* distribution (non oscillating) That Remote can also snap into a inset in the top of the unit just behind the vent at the top. (if you tend to lose remotes) Lastly Energy Impact: This month has been substantially higher than prior month but comparing a full week of use with this unit and being able to reduce usage of the central AC has actually resulted in a slight savings. So overall very happy with this choice. *Note that single hose units will not perform the same*

      OK AC, very poor QC and customer service

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      I got this AC after reading a lot of reviews and online videos. I had to go with a portable AC as the apartment I moved in didn't come with cooling and I did not want to install a window AC as I wasn't sure if my landlord would let me install it. Design and installation The AC itself looks pretty decent, I mean its an AC. First thing I noticed was the weight, it is incredibly heavy which I expected but the wheels don't help much when you're moving it while installing. I have a window which slides side to side (Not up and down). The window is also pretty tall and pretty high up. But the included plastic attachment was pretty easy to install once I cut it to the right size. I only wish the hoses would have been slightly longer for some room for the AC placement on the floor. Function: This is where the nightmare begins! The AC just works whenever it feels like it. Even though the room temperature was 85F and I had set the AC temperature to 61F (which is the lowest it goes), the compressor only comes for only 10 minutes before shutting off. So the room never gets cool. I tried everything for two weeks, moving the AC to a better spot, making sure the hoses were connected correctly etc, nothing worked. I then contacted customer service who gave me the same troubleshooting tips and asked me to measure some temperatures behind the unit and in front of it. I did and sent it to them. Then they inform me that I would have to ship it to their service center and wait for it to be repaired (and also rudely informed me that I would have to pay for the shipping and handling if they didn't find anything wrong with it, great customer service guys!). Well I'm not going to go without an AC for god knows how long they're going to take. Thankfully I found a way to temporarily fix the issue. It seems that the issue I was facing only happens if I used the remote to turn on the AC. It does not happen if I turn it on using the power button on the unit itself. The remote also just goes haywire sometimes and restarts by itself. So for now I'll wait until summer is over to get it repaired. TLDR - Would not purchase another unit from Whynter and would not recommend it to anyone I know because of their customer service and bad quality control.

      Works...for a year


      Pros: Dual Hose, easy to install, easy to pull out filter and clean, easy to use. Cons: Loud (managed to dampen the nose with towels wrapped around the hoses), I had to empty it frequently during the summer (that's to be expected in Texas). Not easy to pull apart and clean. No replacement parts to find online and no real way to fix things yourself if something busts. (The warranty only covers the first few months if you need to send it to Whynter to get repaired. So if you miss the window you're going to have to hand out a lot of money to ship it back to them, maybe the same amount that you spent on the unit itself. The same can be said if you call around and ask someone to inspect and repair the unit.) I bought this originally to keep one specific room in the house cooler than the others. This room is directly in the sun all day long and has three large windows. Originally, the first year the unit worked perfectly fine, even for Texas. However, after one year of year round use this product no longer works like it used to. The air that blows into the room is just kind of cool, not frigid cold like it used to be. I didn't move the product or put it in storage once, so the only thing I think of is that the unit has run out of refrigerant and there's no real way to replace that without professional help and without the proper replacement parts. I'm disappointed that I can't find parts myself and fix it because it's not a bad unit and it did it's job fine for a whole year. It's just unfortunate that after a year the refrigerant is probably all used up and there's no real way to find and buy replacement parts online. It's only logical, in my opinion, that when you put as much money into a product that you should be able to fix it with as little hassle as possible.

      Good Portable AC with good cooling power

      • My Best Buy® MemberMember

      Best buy has the best price for this Whynter AC compared to other online stores, they have free shipping and reward points as well. Unit arrives in 7 days after my order, install it in my small 200 sq feet room. No other portable AC works except this Whynter portable AC. The reason is because this model has the "dual" hose which resolve the "negative" pressure issue of the "single" hose portable AC. Single hose will continue suck in the hot air from anywhere outside your desired cooling area which makes cooling time much longer and the portable AC runs inefficient. When you are the traditional user for the portable AC with the hose to be installed on the window, you should be good and works out of the box.. For my special need, my room doesn't have window so I made two holes on the dry wall and vent out. Make sure you don't connect LONG hose just like me in my first attempt to install, the portable AC will STOP the condenser because the air flow is not strong enough because of the long hoses, I just let the hose vent through the dry wall hole and into the attic without further connect the hose to the soffit, The AC starts working flawlessly and now I have a very comfortable room.

      Cools w/out water build up!!!

      • My Best Buy® MemberMember

      If set properly - ie, do not set to dehumidify! - and is set to cool and fan only, it does NOT build up water - ie, no draining needed. This unit is dual hose and is designed to evaporate the water out of one of the hoses to the outside...awesome. Have been using for a week now and all seems well...excellent cooling and no water to drain! It is fast to start cooling and has a range of suitable controls via remote to adjust to your needs. Be sure to run the fan a while after stopping cooling and before turning off completely so as to evaporate any moisture inside the unit - is a preventative to hinder mold growth inside unit and keep it in shape for a longer life span. I also bought the 4 year extended Geek Squad replacement warranty. Am going to look into putting a mesh screen over the exposed exterior ends of the hoses (the ends sticking out at the window slider) - to prevent bugs or whatever from getting into the hose and unit itself...too bad such a addition (mesh filtration) was not already included (can be purchased as an accessory through Amazon I think).

      Performs well, design is slightly flawed

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      No complaints about performance. Works well and does the job of cooling our upstairs apartment bedroom. It also comes with a well working remote. A couple things I do not like about the design: 1. The casters seem weak because they are plastic. 2. We have a high window and the exhaust is not long enough so I had to place thre entire unit on top of a box. 3. The unit is large and will take a decent amount of space for anyone with a small home. The exhaust tubes are awkward and add to the space eating. 4. It was not in total perfect condition when first opened. There were a couple strange red marks on the body of the unit. Do not know who's fault is, Best Buy or manufacturer? Overall pleased with unit because its helped cool the house but the above design flaws may break the deal for some. I probably would not have bought the unit if I known the issues prior.

      Excellent for a small bedroom

      • My Best Buy® Elite Plus MemberElite Plus Member

      I purchased this to cool my insulated garage. The garage is 20x20 with 8' ceiling, and this unit barely cools it. I understand this unit is mostly designed for a bedroom or living room not a garage but I expected better cooling. If you are expecting this unit to be ultra quiet, forget it! This thing is lound, and doesnt blow air around much. It also draws significantly more electric then what is advertised, with my cheap electric meter I was reading upwards of 1500 watts! I noticed that the cooler outside being provided the lower the wattage, meaning during early morning 1100 watts and during hot afternoon 1500+. I've read from other manufacture that they have to dump water often, but with this unit I've never had to empty any water out! Overall the price to performance with this unit has left me satisfied 4/5.

      Nice looking, not very loud, but will not even cool my 170sq. living room. I ran it for 7 hours. It was about 86 outside, and would only cool my closed off living room to 83. The bottom drain is at floor level, so you can't get anything under it to drain it. The top drain I added a hose to and put a bucket under as there is no where else to drain it to. There is no hole for a hose in the window piece, and I doubt if it would drain uphill as it sits below the window. Not worth the money. I'd like my money refunded.
