Over the moon...
Size: 8,000 BTU
Over the moon with this A/C unit. Plenty of cooling power for my mid-size bedroom. Very quiet (on low fan speed). Reasonable price. Couldn't be happier with my purchase.

If you can't install a window unit, get this portable AC unit
Size: 8,000 BTU
Bought this last summer as a just in case should our central air not be able to keep up with the heat, and our central air died this week and boy was I glad to have this. Out HOA doesn't allow windows units, and this was a well reviewed portable unit. Set it up in about 10 minutes following the clear instructions. They included everything I needed including some insulation strips. Only thing missing was some no residue duct tape to give an extra good seal around the window, but I had some lying around. The unit works great blowing out cold air fast and using the louvers to spread it around. The fan is loud, but certainly no louder than any other portable unit. It kept the bedroom a comfortable temperature even on the hottest of days, and downright chilly at night, just how I like it. I had to use a heavier blanket! While the product overall is great, I think LG could've included an insulated hose sleeve and cut to fit insulation for the window mount, maybe repurposong some of the packing materials for it. These are the two biggest sources of heat getting into a room using this, and that might have helped the unit cool the room down faster using less power. The smartphone app was so easy to use I didn't even touch the included remote control. ... show more

Terrible product and even worse customer service from LG
Size: 8,000 BTU
It works great until it doesn't. When I first got this, it was phenomenal! The air conditioner wasn't super loud and was very efficient. However, after 3 or 4 months, it started to work less and become significantly louder. By month 6 or 7, it was so loud that it was startling to hear it kick on. Around the same time, it was working so inefficient that it was sometimes cooler outside rather than in the room. By month 11 and almost 12 (when the manufacturer warranty was about to expire) i had a "warranty guy" come out and he basically said everything was fine when it clearly wasn't. Now its way past warranty and its just barely over one year old. With my whole experience, I couldn't reccomend LG for their product quality or their customer service. Don't buy this unit or any LG product for that matter. The Amazon one is probably better anyways ... show more

Solid portable AC
Size: 8,000 BTU
I bought one of the "budget" portable ACs which was rated such that it should have been able to handle my cooling task, but it couldn't do that and using it with the remote was an extreme hassle. I sent that one back and bought this one instead. I wanted a portable AC to cool my master bedroom at night because I like to sleep cool and it's extremely inefficient to cool my entire large house to 68° I love the Wi-Fi and scheduling feature; it's miles better than using the stupid remote. Installation was fairly easy but it was a little bit frustrating to install the thing. Also, I would strongly recommend sticking the foam to the window panel rather than the window itself because it made a huge mess of my window since I didn't have the foresight to do that. I have the fan set to high for the white noise while sleeping and make no mistake, it is quite loud on high. It dehumidifies very well, but I also live in a fairly dry climate to begin with, so I can't speak to how it handles a very damp client or how the condensation collection and draining is. Overall it has reduced my electric bill quite a bit since I run this for about 8 hours at night (at approximately 1 kW while the compressor is running) instead of the HVAC (about 4 kW). ... show more

AC Works well but has other drawbacks
Size: 8,000 BTU
I got this as an additional AC unit because my central AC couldn't keep up with the soaring outside summer temperatures summers these days. It was very easy to set up and looks very modern and sleek as well. The actual AC air produced seems very cool and blows out powerfuly. Cools down my apartment well. However the unit is very loud. On the product page it says 49db, but I could not find a way for the AC to function with only 49db (maybe fan only?). When I measured it, the unit was producing 61db on LOW! That's very loud. When on high its even louder. Also when the compressor turns on or off the entire unit shakes and makes a very loud noise. And the app to control it is clunky and sometimes just doesn't work. For example when trying to manually set an up/down vent angle on the app it says "command failed on the product" and doesn't give any more information. However on the same app page you can enable the up/down vent swing and it works correctly. Also the remote and app fight each other and sometimes cancels out your selection. I'd recommend only using 1 of the 2. Also the filter management doesn't work as it resets itself back to 100% sometimes, so I'm not sure when I need to replace the air filter. So in summary, the actual AC functions well and will cool down your apartment nicely. However it is much louder than advertised and the app functions are clunky. ... show more

75 pounds worth of cooling power
Size: 8,000 BTU
Had to get an AC to tolerate heat this summer & opted for LG after conferring with friend who's worked in HVAC for 7 years. Solid unit. Was heavier than I expected, but does perform well (so far) Was lucky and there was no shipping damage apparent when I got this. Make sure to check the bottom drain and properly seat that rubber plug and gently tighten the screw assembly that snugs it into place before operation. Minor thing I've yet to sort is turning the condenser fan on. I get the ON as it says in the manual but when the appliance is powered off it shuts down instead of hearing a fan run. Will update review should things change or I notice excessive leaks or things negative reviews mention. Update: The 10 minute condenser fan setting comes on if you turn unit off by remote. Doing so on the control panel seems to shut down unit immediately, even with this feature on. It cools below the set point exceedingly well during the daytime; but at night seems to creep up above 70. It also seems to keep the rest of the apartment space from going superhot; despite not being open to the main floor most of the time. So far, I'd recommend this unit based on how solid it's performing. No indicator to empty tank yet; and do wish the access point for that was a bit more reachable. A removable tank would be ideal but I'm not sure if LG's engineers can accomplish such a feat. ... show more
