[This review was collected as part of a promotion.] We've had this portable ac about a month now and quite impressed with how quiet it is compared to other window units.

[This review was collected as part of a promotion.] First portable A/C for us and it is wonderful. Cools comfortably a large living room/dining room areas.

DISCLOSURE: I've owned this unit less than a week (my friend owns one as well, which I helped set up) so I can't comment on the long-term reliability, only functionality compared to other units I've owned or used. 【TL;DR】 This is about as good as it gets in portable air-conditioners - and that's quite good. 【INTRO & BACKGROUND】 I've owned several "window shaker" type air-conditioners over the last decade, and one other portable. Window models are slightly more efficient (because the "hot section" sits entirely outside) but are extremely inconvenient to install unless your building is designed with a port for them. Many allow "street noise" through, nevermind being rather noisy themselves. Most portable A/C units use generic "guts" and just replace the outer cosmetic shell. This LG is different, which I'll explain in the pros and cons below. I'm going to start "from the ground up" because LG's design team really hit a home-run with this one. 【FEATURES & PROS+】 • The "smooth gliding caster wheels" are extremely durable, easy-rolling and swiveling - many portables use cheap, "office chair" type wheels that bend, break, and clog with hair. • There's a drain plug centered near the bottom of the unit and connected to a 2-pint water tank. The device evaporates water through the exhaust hose but the tank acts as a buffer if it can't remove enough. The device will shut-down if the tank fills up and will send a warning, including one via the smartphone/tablet app, to empty the tank before resuming operation. • the included vent panels store in a slot built onto the back of the unit - this is a MASSIVE improvement over every other portable on the market where you need extra storage space (or a roll of duct tape) to store accessories • the included window vent panels are thick, reinforced, high quality, non-brittle plastic (ABS or PVC perhaps?) and there are enough of them to cover wide windows. In fact, in my apartments with average windows, there was enough paneling to install in TWO separate windows. I cut an extra port in one of the panels with a Dremel routering jig (see pics) and now I don't have to move the exhaust panel, just the unit. • the exhaust hose points VERTICALLY from the back of the unit - another massive improvement over other brands in which the hose exits horizontally - less clearance is needed, and the hose stores right on the unit • dual-inverter compressor - in short: the compressor motor can run at different speeds which makes it not only more energy efficient but MUCH quieter, especially on start up. Instead of the *CLUNK...RATTLE* on compressor start/stop that gives box units the "window shaker" nickname, this one quietly spools up and down, making it great for bedrooms. • smartphone/tablet app monitoring & control - you can check room temperature, check the unit's status, and fully control it from anywhere in the world. Once connected to the network, the unit can be controlled via app even when you're away from home. (you may need the geeky-kid-next-door to make sure your home network doesn't block this) • app allows for scheduled start and stop, as well as delayed ON/OFF 【QUIRKS & CONS-】 • the remote control is anemic and very sensitive to direction - I've practically given up on it in favour of the smartphone app, and the on-unit control panel (no biggie - I think LG assumed people would use the smart app or panel and the remote was an after-thought) It does stand upright, and comes with a wall bracket, though. • The app is slightly quirky: there's a lot of wasted space that results in having to scroll, and click "expand" tabs. I'd like to see this improved by having all controls on the same screen - simple sliders or radio buttons instead of MASSIVE sections would solve this. • Unit requires a 2.4GHz WiFi network with WPA/WPA2 security (doesn't support WEP, not that you should be using WEP security in 2019). Once connected, the app will find it no matter where you are. (5GHz WiFi or on cellular data) • No ECO/AUTO mode - HOWEVER... the "DRY" mode seems to function exactly as you'd expect an ECO/AUTO mode to: it still uses the compressor to cool the air/dehumidify, but runs the fan on low only, then shuts the entire unit off when the target temperature is reached. 【Conclusion】 Despite the quirks, all of the pros of this unit (smart accessory storage, wheels, low noise level, smartphone monitoring & control anywhere) make it a winner for me, and my friend who owns the same unit. While on my bus commute home, from my smartphone, I can check my apartment temperature, command the air-conditioner to power on, and set a target temperature. I get home and the apartment is habitable. An aside: the smarts and dual-inverter, quiet compressor in this unit are available in LG window models, as well as split systems. If your home has a port for a window type, that might be something to consider. Top marks - this is as good as it gets in portable air-conditioners.

[This review was collected as part of a promotion.] I purchased this unit a few weeks ago from Home Depot and I absolutely love it. The compressor in this AC does not cycle on and off like the other LG units I own -- this makes for a much more pleasant sound environment. The old technology compressors cycle on and off and the two LG LP1215GXR 12,000 BTU units I owned wore out in about a year. I opened both of those units up and the compressor was dead as a doornail. I am not expecting the new inverter unit to have this problem - we shall see. It's expensive compared to the older units. I live in a 4-floor loft so I need to keep a couple of portable AC units running so the large central AC doesn't have to run all the time ($$$). I do like LG ACs and I was about to give up on them but realized I have an old 10,000 BTU unit still running in the garage after 5 years so I was excited to see the new inverter unit and give it a try. One note that will probably mean nothing to anyone reading this review but I rushed to buy this unit after an earthquake here in Los Angeles thinking that maybe my Honda EU2200i generator would run it in case of a power outage. IT DOES! Because the compressor doesn't cycle on and off, my generator runs the AC just fine. I'm very happy about this as now I will have AC in power outages. I am thinking of buying a second unit to replace the garage room unit at some point.

Have used this unit for one summer season (Pacific Northwest) to cool a bedroom. It's effective, cools quite well, construction and fit + finish are good. I chose it because it was touted as the quietest unit in its class, which may be, but when it is cooling it is LOUD—I mean, you-must-use-earplugs-to-sleep loud—even when the fan is on low. Installing the exhaust hose panel vertically is really awkward. If your sliding window has a lip on either side of the rail (as they all do) you cannot pre-assemble the shield per the instructions, because if extended to the proper height, you can't fit the panel into the window frame. Instead you have to collapse the panel, insert into the frame, extend to proper length, set the screws that holds the panel at that length (which because the screws are on the exterior-facing side of the panel means you have to remove the window screen and do this from the outside), and _only then_ can you attach the foam seals on the long sides. Of course, now you've covered the screw heads with the foam so in the fall, to uninstall, you have to first tear off off the foam to expose the screws (ruining the seals so next season you'll have to replace them) and then remove the screws so you can collapse the panel in order to remove the panel from the frame. I can't believe LG considers this acceptable. It's poorly thought out—clearly no one at LG actually tried to install the exhaust panel vertically—honestly I expected better of a LG product. So even though the unit cools well, given its noise level and the lame install/uninstall I don't recommend it, wouldn't buy it again.

[This review was collected as part of a promotion.] Bought this unit to cool down a dental office air compressor and water filtration storage room where everything shut down when the room hit 120⁰. We have not had an issue since installing this unit. Built a custom chimney to exhaust heat to existing ceiling fan. Added a drain hose so condensation runs right to an existing floor drain. Worked like a charm. Rooms stays a lot cooler now and no more issues of shutting down. Highly recommend this machine to anyone in need of dropping temperatures in a specialized room or area.

[This review was collected as part of a promotion.] I am living in Indiana and it is very humid here at times. I am using this air conditioner in my living room which is about 350 square feet. Even on low it cools the whole room very fast and quietly, especially on the low setting. We spent most of the time about 40 minutes to make sure it is tight in the window, getting the unit itself out of the box is a breeze. The hose gets warm after a while just like with any other portable air conditioner unit. Overall it is a great quiet unit. I am happy with it.

I bought this portable AC unit 3 years ago. It was used for only 2 summers and just now it won't work because of a refrigerant issue (error CH 38) which would cost more to fix than buy a new one. That's why these “1 year warranty” products should be avoided at ALL cost. Will NEVER buy an LG product again.

[This review was collected as part of a promotion.] As title says, this unit is a beast in every way... From size, weight and cooling.! After spending a few weeks researching, I purchased 2 of the units from home depot. First thing I noticed was that they are extremely heavy, but the wheels on them help with this unless you need to move it between floors. I installed it onto vertical windows with no issues and found the window kits to be quite well compared to many others. During off season just take away the kit whole and store for next season. Very good cooling, but coming from a place that air conditioners are a part of everyday life, there is no way this unit or any portable unit can cool a 500sq ft room on its own. I would say its good for an avg sized bedroom. Noise level-- you can hear it for sure, but I am a light sleeper and it doesn't bother me. Wifi-- I am heavily invested in home automation but the unit goes offline if not turned on in a day..... Surely something that LG can fix if they read this and want to make this a 5 star product. I mean there is no point in having a smart device that doesn't stay connected to the network. Lastly - - schedule is pretty dumb. Either turn on or turn off 1-7hrs as option. As a smart device it should have a time, days of the week that you can set for the ac to be on or off. Not just when to turn off or turn on "Once" Highly recommend but if lg can fix the 2 above issues it would be great.! Pros

I bought this when I heard it was 44 decibels in sleep mode. I thought it would be perfect until the compressor comes back on. Then it sounds like a jet engine starting up and the blower makes a lot of noise. This is in the middle of the night I had service come out and I am told this is how it works. So now I turn it on low and try to tolerate it. What a waste of extra money for it . Just buy a cheaper one
